This week all about Afrezza How much do you really know about the inhalable Insulet. I had a great conversation with the people who make it Mike Castagna 0:34 For me, it's about using the right product to meet your needs to get you in control. And if you're doing well, great, we're going to avoid the long term complications. But if you're not doing your health, and you gotta really try to find the best set of tools, they're gonna make you successful and fit your lifestyle. Stacey Simms 0:47 That's mankind CEO Mike Castagna. We talked about how Afrezza works misconceptions the worldwide market pediatric studies and lots more. This podcast is not intended as medical advice. If you have those kinds of questions, please contact your health care provider. Welcome to another week of the show. We so glad to have you here we aim to educate and inspire about diabetes with a focus on people who use insulin. And this week, we're talking about the use of the only inhalable insulin, my son was diagnosed with type one right before he turned two, he is 16. My husband has type two diabetes, I don't have diabetes at all. But I have a background in broadcasting. And that is how you get the podcast, I have to say that personally, my family is very interested in Afrezza Benny really would like to try this seat. Of course, as I mentioned in that tease up there, they're looking at pediatrics, he is still under 18. So it's not proof for his age group. But we're watching it really closely. And I have a lot of friends. A lot of bloggers and people in the diabetes community have talked about this for years. And some things have changed. So I wanted to have them on the show and find out more. So a little bit of background for you. If you are brand new to all this, Afrezza was approved in the United States in 2014. And the company that makes it is mankind. For a while it was sold by Santa Fe, but then mankind took it back. It's one of those things where sometimes the business side seems to have gotten more attention than the product itself. So what is Afrezza it is a powder, it comes in cartridges, and you suck it in you inhale it with a special inhaler device. To me, it looks more like a whistle than a traditional inhaler like an asthma inhaler. It's not like a big tube. I'll link up some photos in the show notes. I'll also link up the Afrezza website so you can learn more and see their information. And my guest this week is Dr. Mike Castagna, the CEO of mankind now he has a Doctorate of pharmacy, he worked as a pharmacist behind the counter for CVS at the start of his career. But then he went back to school and he got an MBA from the Wharton School of Business. He's fun to talk to he doesn't mince words, and he truly believes in this product, I do have to tell you that Mike mentions monomeric insulin a couple of times, I'm going to come back after the interview and explain more about that give you a better definition. All you really need to know is that it's faster than how liquid insulin is made. And all of that in just a moment. But first Diabetes Connections is brought to you by Daario. And over the years I find we manage diabetes better when we're thinking less about all the stuff of diabetes tasks. That's why I love partnering with people who take the load off on things like ordering supplies, so I can really focus on Benny, the Dario diabetes success plan is all about you all the strips and lancets you need delivered to your door, one on one coaching so you can meet your milestones, weekly insights into your trends with suggestions on how to succeed, get the diabetes management plan that works with you and for you, Daria is published Studies demonstrate high impact clinical results, find out more go to my dario.com forward slash Diabetes Connections. Mike, thanks for joining me, I'm really excited to catch up. And look, I'm stuttering because I can't believe this is the first time we're talking to you. But thanks for coming on. Oh, thank you, Rodney. I'm super excited before we jump in and start talking about Afrezza Can you give us some perspective kind of dial back because mankind is not. It's not a name that came out of nowhere? There's really important history. Can you kind of talk about that a little bit first? Mike Castagna 4:14 Sure. Mankind comes from our founder named after Al Mann and Al Mann was a true innovator. He started I think 17 companies and everything from the cochlear implant to the pacemaker to insulin pumps that many of us know today as Medtronic used to be called mini med. And Al Mann built the insulin pumps over the 80s and 90s and was very successful and sold that company to Medtronic. And then he took literally $1 billion of his own money and invested in mankind. And he had put this company together through three companies he owned the technology to make Afrezza was really a combination of companies and the reason he was so dedicated as he saw in the pump market, which we now see today on CGM was that the variability in mealtime control was so high and the fluctuations you see that the influence takes about an hour and a half to kick in. And it's hard to get real time control if you can't get a faster acting insulin. And so he set out to make a real time acting insulin, so phrases and hailed as monomeric. And that was really what the magic was in our technology making a dry powder was was free dryness, if you heard of dippin dots ice cream, we have basically large dipping machines in our factory, but we free dry the particles to make a freezer and under stabilize the monomeric form. So when you're inhaling, you're inhaling influenza, as soon as it's in your blood is active, or when you inject it has to hold hexamer and has to break down there were about 45 minutes. And that's how you can make it stabilize an injectable form. But it has to break down and then it starts working. And that's why there's always this lag effect between we see injectable and foam in and help us is very different products were categorized with real time rapid acting, but the name mankind comes from elmen and the guy who probably 60% of people on pumps have their own pumps that he created. So amazing gentlemen, huge contributions to diabetes and millions of people were alive today because of his work and his generosity and roven to take that forward here and kids and frozen inhaled insulin. Stacey Simms 6:06 I mean, never look at dippin dots the same again. Mike Castagna 6:10 I see a large factory of they don't like it, you know, we can always make different types of things don't go well. Stacey Simms 6:15 I love it. Let me ask you to go into a little bit more detail about how someone who uses Afrezza would actually use it. Can you talk a little bit about like a daily routine? Mike Castagna 6:25 Yeah, I mean, I know, you know, well, you're in this disease. I mean, people sometimes graze all day, and they just kind of ride their sugars and take a little bit some along the way or many boluses. And some people you know, eat once or twice a day, or some people, you know, carb restricted and everyone has a different way. And I think that you know, the big thing difference was for the patients that I see is, it's in the moment, meaning you don't have to time your meal and your insulin, when you're going to take it and where you're going to be. As soon as your food arrives. You take your first dose. Stacey Simms 6:50 Most people I know who use Afrezza take a long acting insulin with it. Is that pretty standard for people with type one? Mike Castagna 6:57 Yeah, I'll take one year, right? Yeah, you need a basal insulin of some sort, you know, and, and a meal time was held, we do have some patients on pumps where they will use their punches for their basil, for example, and use a phrase for real time corrections. So you know, the average patient is very different. We have some patients that are type twos, you know not not on any basil, you'll need to be on basil for if you're type two. But if you're type one, you need to basil, long acting insulin, and you need your meal time. And we know the biggest problem in this country is still mealtime control is the number one thing people with diabetes struggle with. And it's a big reason why, you know, six, or seven or eight, you know, eight out of 10 people basically are not a goal on insulin because of the mealtime control. So it's a daily challenge for everybody. Stacey Simms 7:39 Can you talk a little bit about how Afrezza is kind of measured out? Because when we think of mealtime, insulin, everything's a carb ratios. And especially as I mentioned, if you're on an insulin pump, you're you're putting in the carbs that you eat. So how does that work? Mike Castagna 7:51 Yeah, it's funny, I get into many debates with people because, you know, I'm a pharmacist by training, but I'm not the smartest guy. But I couldn't do all the work people do every day to influence sensitivity ratios and carb counting and timing. And all I can tell you is everyone's masks off by 50%, one direction or another. And so we have this false pretense that we're that accurate. And dosing are influenced by down to the half a unit or one unit. And the reality is your angle of injection can decrease, you know, change your absorption by 25%, your site of injection can change absorption, your your stress level can change your impact with your insulin, there's so many things that go into your daily dosing of insulin, that, you know, being that precise, down to the unit is not as accurate as we all think. And I think that's that's one of the misnomers of, you know, the timing is what you really struggle with when you're using injectable insulin, and you just don't know what's going to happen. You know, when people I guess doctors often you know, you don't have to carb count with Afrezza . And they give me funny looks. And the reality is, you know, we've never done a study where you're carb counting to get your dose of insulin, that's, you know, so becomes a four 812 dose linear all the way up to 48 units, it's additive, and you just got to be close enough. And so it's about a two to one ratio, you know, there's no direct pulmonary equivalent to injectable insulin, unfortunately, but, you know, people are taking five units of injectable insulin per meal, they're gonna need about eight units of Afrezza and maybe even 12. And you're gonna figure that out, it's your first meal or two what what the right dose is for you. But you just got to be close enough. And that's a big misunderstanding for people of how accurate the dose has to be. This is the sixth dose cartridge is a big problem. I know plenty of type one patients who take for a 1224 meal, especially they haven't Chinese food or sushi, they just they dose a lot. So I think that's something people have been comfortable, so dramatically different than anything they've ever been trained or taught in their history of living with diabetes. Stacey Simms 9:36 I would assume that a prescription for Afrezza comes with a doctor's visit where someone whether it's someone who works for Afrezza, or the endocrinologist talks to you about how to do this dosing. You said you figure it out, but I've got to assume that you're not just sending people home with this inhalable and say, just test it, I mean, right somebody, you're at a ratio Mike Castagna 9:59 and I think That's the key thing is, you know, having patients understand because it's odorless and tasteless. So you inhale, and you're like, what did I get it? And I'm like, yeah, if you inhaled, and I have the second, it's in your blood, it's in your lungs, it's breath activated. So you can't really, of course, you can try to mess up something. But we have something called Blue Hill, where we can show proper inhalation technique in the office on an iPhone app or an Android. And so you know, we hope that patients are being trained either by our trainers or the doctors offices, and will propagation technique looks like that's number one. And then number two is the right dosing. And as you know, individualized dosing is important and fun. And, again, that's why I say we take a lot of the math out because it's either gonna be a four or an eight, and all of a sudden, you're like, Oh my god, I'm gonna take an eight units, it's a lot it's really not when you're taking inhalation units versus injectable units and that's what people got to get comfortable with if their first or second dose so they really do figure out this meal did this or pizza is going to take longer so pick another dose and now our people do figure it out pretty much within the first week. And then there's one thing actually I want to mention because I often forget this is because injectable insulin is such a long tail it's in your body for four to six hours before it's out and that feeds into your basal rate your long acting and so when people switch over presence pretty much out of your body in a net roughly an hour and a half. Sometimes people need to adjust their basil and that's something to watch out for if you do switch to Afrezza enter you're struggling with with some of the basil rates. Some patients you know I hear people anecdotally you know, we don't want to study their the bump up their basil 10 15% on Lantus. And I've heard patients on to see that because it does have that long tail of down there in front sometimes on the basil. So there are the other metrics patients have to watch out for when they are switching to the product. It's not just the uptime, it's also something that basil where you look at Stacey Simms 11:38 I have a question and I i apologize because it's a it's a bit ridiculous. I'm gonna ask it anyway. Right back to the interview in just a moment. But first Diabetes Connections is brought to you by Gvoke Hypopen. And our endo always told us that if you use insulin, you need to have emergency glucagon on hand as well. Low blood sugars are one thing we're usually able to treat those with fast acting glucose tabs or juice. But a very low blood sugar can be very frightening. Which is why I'm so glad there's a different option for emergency glucagon, it's Gvoke Hypopen. Gvoke Hypopen is pre mixed and ready to go with no visible needle, you pull off the red cap, push the yellow end onto bare skin and hold it for five seconds. That's it, find out more go to Diabetes connections.com and click on the Gvoke logo. Gvoke shouldn't be used in patients with pheochromocytoma or insulinoma. Visit Gvoke glucagon.com slash risk. Now back to my interview with Mike, where I will ask that ridiculous question. You had mentioned it's tasteless, odorless, I recall hearing and I'll have to fact check this. But I recall hearing that years ago dandruff shampoo, they had to add like that tingly feeling because people didn't think it was working like it's totally fake. But people just didn't believe it was a medicated shampoo because it didn't have an unpleasant sensation. Have you thought or talked at all about adding like a flavor or a feeling to so people really know that they got it? Or is that just really bananas? Mike Castagna 13:12 If somebody might company come and talk to you ahead of time? There's somebody internally who wants us to look at like cherry flavor Afrezza especially as they go into pediatrics? And the answer is, look, there's blueberry Metformin because the metformin smells awful and tastes awful, probably. So you know, those things are possible. We've never done them. And to my knowledge in this industry with dry powders, it is a question that came up recently. Is that should we be thinking about the cherry flavor Afrezza or some other flavor? And I think the answer is TBD. We I don't know what the date is on inhaling the food coloring dye or whatever. Yeah. But that's some of the stuff we have to justify that it's safe and effective. And along with FDA would want us to test but they come up recently and another internal discussion. And since you're asking, I think we'll look at it, even if maybe there's a way to even show a placebo, that's a cherry flavor or something right a one time dose to see what it's like. So I don't know. But now, but people like I said, it's sometimes you get a call, like you know, when you take a phrase of one out of four people will get a cough initially. And generally there were the first four weeks that cough goes away 97% of the people. So I always tell people, you're having a cough, like as long as not interrupting your life, it should slowly get to your first refill. And it should be mostly resolved by that your body's getting used to putting a powder in your lungs. But that's uh, you know, when people ask, what's the difference between injectable and inhaled in terms of safety, you know, you're putting a drug powder in for the first time in your body and your body could choose that. And the number one thing that's different, were injectable insulin. You know, you have other other things. You're dealing with injection sites and pump sites and scar tissue and things like that. Stacey Simms 14:48 Does the body actually acclimate to the powder or is it just a question of someone gets better and used to the inhalation sensation? Mike Castagna 14:55 You know, it's it's a good question. I don't know if I have a black and white answer here. bodies give. Yeah, my guess is the body's getting used to putting a dry powder in and just exit and you get used to like weed. You can drink a glass of water before and after and help you minimize it. But it's generally like that's what it feels like it's not a productive call frightening, there's not a call to happens 10 minutes later, it usually happens. We have to inhale. Stacey Simms 15:17 You mentioned BlueHale , can you tell us a little bit more about what that is? Mike Castagna 15:21 Yeah, so BlueHale is to two different things. The first one that we're looking at is with the patient training device. So we can show you whether you had a good emulation or not a good emulation and show you that technique. The second version, actually, you can detect with those you put in the cartridge and hilar. So it has a proprietary software there that we can see what cartridge you put in for the adapter. And it'll tell you on your app, if you took a for a 12 or 16, how much you took in that session. And then we hooked integrate that with the CGM data. So now you can show those response curves on CGM one day and eventually I want to get into AI and predictive analytics. But we're not there yet. But we think that's the magic of what people really want, which is one that I use the thing when you live with diabetes, you just must remember and be that perfect to know exactly what those you did with them. You took it, what meal you were and then I simulated being a patient for a week. And I realized I could remember if I took a four and eight, I take a six or 620 is that 30 minutes or one hour like it was it was amazing. When you just think about life and people are human. They're there. They're human. So they're not keeping track. And they're not that accurate. They're just estimating. And that's when I talked about the dosing of insulin, like we're always estimating everything, we're estimating the time our food is going to come and how long it's going to work. You know, what the carbs are? How much am I gonna eat or drink? Like, it's all accurate? It's all off. None of it's that accurate. That to me is the thing I realized when I was thinking of doing one of those a disease, you don't you think they're perfect. They're not. They're human beings. And that's when I see one out of five doses of injectable insulin are intentionally missed. And the predominant one that's missed is actually lunchtime, which makes sense to wear out in a social environment. They don't want to inject. And by the time they get back, they forget it's probably too late. Or you're already high. Stacey Simms 17:00 What do you mean by intentionally Miss? You mean? Like they people just forget? Mike Castagna 17:03 No, no, they intentionally knew they should take a dose of insulin, but they're in a lunch conversation, or they forgot their insulin in the office. Or they'll have their CGM receiver on the bike, or they essentially don't they miss one of the five doses. So if you're missing 20% of your doses, it's really hard to get in control. And there's all kinds of reasons, but that's intentional omission versus unintentional. Which is I forgotten. Stacey Simms 17:23 I'm curious what the sources on that that's, I mean, I don't doubt it. I'm just curious. Mike Castagna 17:27 Yeah, I couldn't find it. follow up on that. I have your email, I'll look for it. Yeah, no, because I didn't believe it. And then there was a study done with one of the pens coming out that has digital connectivity. And I looked at it and I looked at the data and like, wait, if a person needs three times a day, seven days a week, that's at least 1721 doses, right? And I think the average person is taking like 1212 shots a week. And I'm like, Well, that doesn't make sense. But you realize, you know, again, we're human, people aren't always as compliant as we want, or they don't eat three times a day perfectly are the two big meals, you know, everyone does something different. So having insulin that meets your needs, and your lifestyle, I think is really important in the world. And you know, look, we like our products, obviously, we're here, we love the Afrezza. But But I also just for me, it's about using the right product that meets your needs to get you in control. And if you're doing well, great, you're gonna avoid the long term complications. But if you're not, you own your health, and you got to really try to find the best set of tools that are going to make you successful and fit your lifestyle. And, you know, obviously, we're not doing well when 80% of people on insulin on a boat. I mean, that's that, to me is the number one thing, I look at this country and say, well, despite all the adoption of pumps, and technology and CGM, we still have not made a meaningful difference in percent of people to go. And that's frustrating. Stacey Simms 18:35 Way back in the beginning of this interview, we talked about Chinese food and pizza. And I'm just curious, you know, these are things that are hard to dos for, because they they kind of they come later, you know, what most people listening are very familiar with, and I think probably have their own system for dosing, whether it's an extended bolus or injecting more than once. How would you do something like that on a Friday? Is it a question of you would take what you think when you're eating, and then again, in a bit later, like, how do you account for those high fat foods? Mike Castagna 19:02 Yeah, you know, I'm going to pick on Anthony Hightower, who I know you interviewed before. So I actually met Anthony on a bed over social media. And he had showed me your servers where he ate pizza. So I'll pick on him because I want the public discussion here, sir. He pizza and his sugars are basically flat over the two, three hours post meal. And I said, I'm like, shocked. He's like, this is something people cannot do naturally on the history of injectable insulin, they they always struggle. And when you eat pizza, you're going to struggle not just for hours, but potentially for the next day because just throws everything off. I think in his case, right? I've watched him he took a big dose up front, you know, let's say he's gonna take 12 units of injectable he took 24 units of Afrezza. And then he washed her wasn't an hour, and then an hour she was above where he started. He took another dose, maybe took a four and he has to tap it off. And then an hour later, just thought was too high or not right. But you can always keep your sugars in that kind of control. That's one of the studies we did back in 2018, called this test study was showing that you could do as soon as one hour with no more hyper risk. And that was a big concern of people, how can I do that one hour, well, pretty much hit its peak effect in one hour. So if your servers are still moving in the wrong direction, you can correct them at that point. And so that's where someone on pizza or Chinese food, like, yeah, it's a high dose up front and may manage it through the whole system. Or they may see an hour or two later, they're still high and to take another dose, that they can bring it down at some point. Stacey Simms 20:20 Alright, let's talk about the big questions that people generally have. And that the one I hear the most is, Is it safe? Right? Is it? Is it okay to inhale this stuff into my lungs? Can you talk about the studies that you've done? Mike Castagna 20:32 Yeah, I think if we were able to make inhaled insulin 100 years ago, we'd be scratching our heads those who would inject themselves three times a day. So I think it's just an unfortunate matter of 100 years of difference. But we studied a phrase that probably over 3000 patients 70, some trials $3 billion over 20 years, like, that's how much money time and energy is going into prove the safety and effectiveness of this product. And you know, and I tell people like you know, there is no data to say that it's not safe. We have all the rodent studies, all the CT scans that along looking for fibrosis looking for pulmonary issues, we found nothing. So it doesn't sit in the lung. There's an old product called exubera on the market years ago. And exubera was a sugar based manatal formulation which got absorbed over time into your lungs in a friend this case, the it's got water and human influence. So when we ask about what ingredients are you worried about the human influence, human influence, it's the whole AI base, but it's human influence characteristic, and water is purified. So we know that safe and the other only other carrier in our products SDK p which is a excluded product that is not metabolized in the body, it's just 100% extruded. So you know, there's three ingredients in our product. One is human insulin, one is water, and one is tkp. And SDK p comes out of the system. So I don't I don't think the body is afraid of human insulin. And what are so I think, you know, I always struggle with this topic. Because, you know, what happened is there was some lung cancer cases and Newser, were they there was a couple of our data. But you know, in the seven years since FDA approval, we've seen no safety signals come up in the postmarketing. We have almost 10,000 patients on the presidency. I know people in the drug for 1012 years. And so, you know, we don't see anything that gives us concern. And we're going into kids now, who would have to take the drug for 40 5060 years. So I think it's hard to prove something that you've never seen. But safety comes with time. And I think the good news is product has been approved by the FDA for seven years now. And we've not seeing any safety signals in our database, which we look every year, our rems program ended early by the FDA and and we've continued to show good data and all the studies we've done, we've not seen anything new come up in our anywhere safety issues. So if you're, you know, the populations, I would say if you have COPD, and asthma, this is not the right drug for you. Stacey Simms 22:41 So a dumb question, though. If you have diabetes, and you smoke, can you get an Afrezza? prescription? Mike Castagna 22:48 We would say you should not? Yes, we have a warning for that. Stacey Simms 22:52 Well, I just wanted to be clear that there was an actual warning, it wasn't just a please don't because it's bad for Mike Castagna 22:57 warning. Don't Stacey Simms 23:00 tell me about the study with kids. Because I've got one, I've got a 16 year old who was quite interested in this product. Mike Castagna 23:06 Yeah, no, I just found out Unfortunately, the dagga three year old cousin in the family have just come down with type one. And she will, she'll be four and our studies gonna go down to four years old to 17 years old, when we launch it. So I'm excited, we had to do a study to show that the pharmacokinetics and dynamics of inhaled insulin are similar in kids as it as adults. And so once that study was complete, we we wrote a protocol down to the FDA and said, We'd like to go into the next phase, and now run a larger study head to head against the standard of care. And the FDA has pretty much signed off on that protocol at this point. And we have contracted with a third party to now run that trial. And we'll be having our investigator meeting here in next month. And so hopefully, we'll see our first patient in the four to 17 year old range, probably here in September, October time frame. So super excited, long time to get here took too long from my perspective, but can't wait to help kids. But our founder Outman invested, he became very wealthy when he sold the insulin pump company. And he took $1 billion of his own money and made Afrezza inhaled insulin because he felt the problem with the injectable subcutaneous delivered insulin was it just took too long to work. And you know, somebody has an hour lag effects from food. That's real timing, it's always hard to catch those two even. And so he really wanted to make an inhaled insulin that really mimic a physiologic insulin that you see in the body. And he felt the only way you could get there was through a dry powder, lung delivered instantaneous insulin, you can also get there through an implantable pump. But that didn't work out when they tried that back in the 90s. I recall. So people got infections and things like that. So that would that didn't work. So they really were going to get a in my mind that physiologic inform that's gonna be monomeric stabilized is probably going to happen only through the inhaled route. So we have we have to get comfortable with this from overall efficacy and safety. Otherwise, you're not going to really ever get this control that people are looking for real time. Stacey Simms 24:55 No man, he lived long enough to see Afrezza approved, didn't he? Mike Castagna 24:59 He's All approved. And unfortunately, I'm here because he died on my daughter's birthday. So I was debating whether to come to mankind or not. And I'm very superstitious, the Al Mann pick the day he died. And he died February 25 2016. And then they made decision to join and help save the company and save a frozen kick on the market. Because I think, you know, I saw all these wonderful patients stories online. And I said, these patients like Anthony Hightower is one of them, what they did something that no one else did, they did something we never did in our clinical trials. And so I got to talk to them. And I realized we just didn't dose it properly. So you go back to the development of the product, a lot of the challenges were under dosing because everybody's trying to compare one to one to injectable insulin, and therefore one of underdosing patients, and therefore, they got equal outcomes didn't do any worse than injectable insulin per se. But could they have gotten better outcomes if we dosed improperly? Right? And I think that's, that's the state of we're now trying to generate to show that the kids buddy now be head to head, or if he knows him properly, what happens? Right, and that's we're really focused on right now. Stacey Simms 26:01 Is there anything that you wanted to talk about that I haven't answered? Mike Castagna 26:04 No. I mean, we're only available in the US, we're in the process of going to Europe. So I don't know if you have any. Yeah, we do. Though, so I know, we have patients on a name patient basis in Germany, and UK and Italy. So you know, their governments are actually important a president and pay for it. We're in the middle of filing for Australia. We were approved in Brazil, and we're going to India so so you'll see this more and more around the world. You have listeners in those markets. There's not gonna happen this year. And hopefully, the next year or the following year in some of these markets, we'll be looking at bringing it to more patients in those markets. Stacey Simms 26:37 Well, and just got a big approval here in the United States for Medicare patients. Right. Mike Castagna 26:42 Yeah. So that one, I, you know, we get a lot of questions on that one. And so you know, this market CGM patients were told you need to be injecting yourself, I think four times a day, we couldn't get your CGM. So then doctors were not getting patients Afrezza. And so we were able to ask CMS to change that, and they did to the year but rather haven't done they're not done. And so here we are a year later that that policy is now being updated. I want to thank CMS and all that you're helped make that happen. And I think it helps in people in CGN, because I understand that removes some of the other requirements to get CGM, even an injectable these patients so little mankind was the one who started that process. And then we're able to help a lot more people. So it's great. And we're trying to get Medicare $30 a month insulin. So we have Medicare listeners. And you know, we're trying to make sure we help get patients access that are on Medicare. I think that's important. Stacey Simms 27:33 That doesn't stack up in terms of cost in the United States. Mike Castagna 27:36 Yeah, I mean, you know, fortunately, the billion dollar debacle in this country is drug pricing, as we all know, and as a pharmacist, I know firsthand when people go through an LMS they're on how many co pays are on. And so we really have tried hard to make sure that no patients pay no more than $15. So we have copay card programs, we actually have a free drug programs, they really can't afford it, we'll give it to you for free. If you're going through the prior authorization process, we give it to you for free while you're going through that. So we all want payers and reimbursement to be the excuse of why a patient can't get access to our product, we think that people will do well on our product, we're willing to take that bet that they'll see good results. And if they see good results, the payers will usually pay for it. And it says you may or may not know that there's a monopoly in diabetes between two insulin players, and three payers, who are all working together to make sure there's no competition. You know, that's unfortunate, but they pay to make sure that patients have a difficult time getting Afrezza . And that's always one of my frustrations of competition or diseases. You know, 400 years, we've seen the precise the dispensing from 20 hours a while 95 and let's say miles, hundreds of dollars. You know, for me on the payer side, we want to make sure patients we try to bring it down to about $15 on commercial and Medicare, you know, they generally pay comparable to what they would and some Medicare plans a little bit higher I can you know, that's a hit or miss when you when you go to submit for reimbursement, but we try to do everything we can to make sure people will have access to our product Stacey Simms 28:57 $15 for $15 for commercial patients, no, no, but what is it? What is it for? What do you get for $15? Is it a month? Is it a Mike Castagna 29:05 my week? Yeah, whatever, whatever. You gave two boxes, three boxes, whatever is on that prescription for that month, Stacey Simms 29:10 for the month. Okay, I didn't mean to interrupt you. Mike Castagna 29:12 I don't think I know, I was gonna say I forgot we actually have a cash pay program. And people are paying cash for their insulin. And we do see several 1000 people a month paying cash for injectable insulin, we have influenced savings comm where it's $99 a month for frezza. And you know, can you a bigger box or more doses, you might pay 199 but we tried to make the cash price, you know, roughly $100 a month. If we if you had no insurance, for example. Stacey Simms 29:37 I'm not sure you can answer this question. But I will ask it anyway, is the biggest challenge for you all the failure of exubera? Is it just people not knowing what this is? You know, as you move forward, you know, what is the big challenge to get more people to adopt us? Mike Castagna 29:51 I mean, for me, the biggest challenge are the doctors. We created a program we basically gave it for free to patients for two years for 15 bucks. Like no no priority. Nothing, we just charge you $15. And that didn't change a lot of doctors from jumping on board. And doctors just don't know our data. And so they think this product doesn't have a lot of data behind it. And they don't know our data, they don't know. Like when I would ask a doctor, how fast from the time you inject your bolus, your pump to the time you look on a CGM, that your institute sugars are coming down, and I get in these endocrinologist, I'll get five minutes and mediate and 20 minutes an hour, the answers, I need 90 minutes, 220 minutes, that's the answer. And so they don't even know the pharmacokinetics and pharmacodynamics differences between injectable insulin inhaled, and then you have doctors, right, you know, calling some of these ultra acting drugs faster, we'll look at the package inserts, they're no faster than their old products. And there's a lot of misperceptions out there some of these newer launches of old tracking insulin, and to me they're, they're really not that much different than the predecessor and look at the data, you know, there's not a faster, there's not dramatically faster onset or offset or, you know, a one c lowering or weight gains on very much the same. So, no, I think it's just a matter of doctors trying to really understand the data. Stacey Simms 31:02 Before I let you go, are there any plans in the future to change anything about the way it looks? or different colors? I mean, I know it sounds kind of silly, when you're just trying to get people to adopt the new technology, but from a user standpoint, and look, I know, you've heard all the jokes of my friends who use this will make you can't comment on designers. They don't say anything, they'll make comments like, you know, taking a hit or whatever, right? I mean, it's it's inhaling, it's this little thing that you're, you're inhaling, it looks a certain way. I'm curious if the cosmetics of it are anything that are on your radar, or needs to be improved even? Mike Castagna 31:36 No, I mean, I think when you spend, you know, $3,000,000,000.20 years doing a new drug development or taking 100 year old product and reinventing it, you had to get that right in terms of device design and airflow dynamics and consistency. And those. And I think all that's really important because, you know, misperception that oh, my God, it's going to be less can be more variable than injectable insulin. And the data just doesn't support that statement. And so for us, we have one of the world's most unique installation platforms across the entire pharmaceutical industry, we deliver more power to the lung, the most technologies out there. So that's why you can get consistency, those two those, and you don't have a lot of variabilities, because our technology and our device is called a low velocity inhaler. And what that means is there's a resistor that helps slow the powders as they're coming out of the inhaler. So they get deep into the lungs. And that's why you get that nice absorption curves that we see. And we're most inhalers or high gloss inhalers. So it's just enough sucking air as hard as you can, and hoping you get you know, 20 30% of lung drug into your lungs, and mostly stuck in your teeth to device in the back of your throat. That's most dry powder inhaler technologies out there today. And so that's something unique to us and our technology and our device, they all work really well together, you couldn't just take our powder and put into another inhaler, and or just as well would not work. So yeah, we're pretty happy with the device I we are going to other diseases. So you know, we're we're going down to the FDA with our partner for an approval in October for pulmonary hypertension patients. And we have several other orphan lung areas we're going into to help more patients with lung disorders. So you know, I think that's important, like our, our technology, our inhaler, our platform is gonna be used in more and more patients over the next decade than just diabetes. Stacey Simms 33:13 Well, that's what I was gonna ask is, if it works, so well, you know, will you partner with other medications? That's great to hear. Mike Castagna 33:18 Yeah, you know, we're really busy, we probably have about 10 to 12 formulations of products working on this year and five marone products in the pipeline. And so it's it's a really good time of mankind, we're super excited to be here. And it was a turnaround, the company struggled for many, many years. And we're on our way to success. And I think, firstly, you'll be you'll be hearing more about it. So I know it's been a long time. And maybe you didn't talk to us yet. But hopefully you'll talk to us more and more as we continue to generate new data and more more patients start using it. Stacey Simms 33:45 I'd love to, I'd love to, especially with the kids programs. And like I said, I've got a 16 year old who is very curious about this. And, you know, once once safe and effective. Once we get all that safety stuff in here. It's mom says, you know, I'll definitely I know, I would like to check it out. So I really appreciate you coming on and spending so much time with me and my listeners and explaining all this and we'll definitely talk again. Thanks, Mike.

I also have a transcription as well, sometimes those podcast players don't display the show notes and the links. So if you have any trouble, just go back to Diabetes connections.com. And I just want to say that I did reach out to have Mike or somebody from Afrezza on the show. And you heard him say, you know, it's been a while, um, you know, it just took a while to connect to the right person. Let's just say that, and I will have them back on because lots of good stuff is happening. As you heard. I want to take a second and kind of explain Monomeric insulin and, you know, I'll be honest with you. The scientific points here are really not my strong suit. I'm a communications major, right. So I did what I always do, and I am People who know a lot more than I do to help me explain it. I went to the Facebook group Diabetes Connections as a group. And you know, I said, How do you explain monomeric insulin I know it's faster. And Tim Street, who is just wonderful and runs the diabettech.com page that's like diabetes tech diabetic, and I'll link that up as well. He provided this explanation, which really brought it home for me, and boy, I hope I'm pronouncing everything correctly. So Tim wrote, insulin naturally links its chains together to form stable molecules. Typically it connects two together and then links three of those two chains together. Additionally, to create six This is highly stable and described as hexameric. In order to use these chains, you have to break the molecules apart to single chains, which are monomers. Typically fast acting insulins are stored as dimers, two monomers connected, which are easier to split, then hexamers. by storing the insulin as a single chain, a monomer, the body doesn't have to break the chains to instantly use the insulin molecule it receives. And that is why Afreeza wraps the monomeric form in the capsules, to make it ultra fast. Thank you, Tim, that actually made a lot of sense. I gotta tell you, we have the smartest people and the kindest people in this Facebook group. If you're not there yet, and you want to join, come on in, I highly recommend it. You don't have to be a Tim Street. You don't have to be able to explain these concepts. You do have to be nice. And you do have to not post a lot of drama. I'm very tough on my diabetes groups. I run two of them. They're very nice and friendly places for a reason. But Tim, seriously, thank you so much. That was a great explanation. And I really appreciate it.

I packed up a bag for Benny to bring to the nurse. He brings his daily supplies with him every day in his backpack. But of course, like most people, our nurse has backup supplies for him. So I put those together. He brought them in along with our plan or orders, you know from our endo. And that was it. I haven't set foot in the building. I'm not sure when I will go in or if I will go in probably when you forget something or they run out there. But I've never done less work.

On today's 'BradCast':  Americans are still paying the price for Ronald Reagan's 1987 Executive Order that gave away the taxpayer store to Big Pharma. The CDC recommends that Americans get newly reformulated, bivalent COVID vaccine booster shots before Halloween to lower the risk of infection, hospitalization and long COVID. Updated vaccines are necessary because, despite billions of dollars in taxpayer funding to develop them, private pharmaceutical giants refuse to give up their patent rights to make the vaccines available to the world, giving ample opportunity for new variants to emerge, extending the pandemic and in turn delivering more profits to Big Pharma. ERNEST A. CANNING, legal analyst at The BRAD BLOG, explains how we got here:  from Reagan's 1987 'gift' to wildly profitable pharmaceutical companies and how it enabled the explosion of patent abuse by Big Pharma, to why there are no easy fixes, and what can be done to repair the system. Canning also offers brighter news on a landmark effort in the state of California to cheaply manufacture live-saving insulin to bypass Big Pharma's outrageous prices. Also today:  new developments in the broadening criminal conspiracy investigation by Fulton County, GA District Attorney Fani Willis into Donald Trump's multi-pronged, failed efforts to steal the 2020 Presidential election. The founder and CEO of outdoor gear brand Patagonia announced he has donated the $3 billion for-profit company with the mandate that all of its profits go to combat the climate crisis.

Diabetic patients may someday reduce their insulin injections and lead more normal lives because of new insights gained through irnovative space research in which insulin crystals were grown on the Space Shuttle. Results from a 1994 insulin crystals growth experiment in space are leading to a new understanding of protein insulin. Lack of insulin is the cause of diabetes, a desease that accounts for one-seventh of the nation's health care costs.

This article is from Diabetes , volume 62 . Abstract Obesity is associated with insulin resistance, a major risk factor for type 2 diabetes and cardiovascular disease. However, not all obese individuals are insulin resistant, which confounds our understanding of the mechanistic link between these conditions. We conducted transcriptome analyses on 835 obese subjects with mean BMI of 48.8, on which we have previously reported genetic associations of gene expression. Here, we selected ∼320 nondiabetic (HbA1c

This article is from Diabetology & Metabolic Syndrome , volume 5 . Abstract Aims: Prevalence of Type 2 diabetes mellitus among Sudanese population was found to be 3.4% and associated with high rates of complications and obesity. Different adipocytokines are secreted from adipose tissues, among them adiponectin, which was shown to have insulins ensitizing properties and anti-inflammatory, anti-atherogenic effect. The aim of this study was to characterize type 2 diabetes in Sudanese diabetic subjects and controls in respect to hormones influencing or influenced by glucose metabolism. Methods: 104 type 2 diabetic patients (45 men and 59 women), and 75 matched control subjects (34 men and 41 women) were studied. Fasting serum samples were used to measure adiponectin, leptin, insulin, proinsulin, ghrelin and glucose. Body mass index, insulin/proinsulin ratio and (HOMA) insulin resistance and beta cell function were also calculated. Results: Adiponectin serum concentrations were significantly lower in subjects with type 2 diabetes compared with controls subjects (P = 0.002), comparison between males and females did not reach significant levels in both diabetic (P = 0.06) or controls (P = 0.16) groups. In the diabetic group adiponectin correlated positively with serum glucose, negatively with serum proinsulin and HOMA beta cell function (P = 0.03) respectively and serum ghrelin (P = 0.003), but not with BMI, HOMA insulin resistance, insulin or leptin. In controls serum adiponectin correlated negatively with BMI (P = 0.002) but not with other variables. Conclusions: The findings of this study suggest that, adiponectin concentrations independent on BMI as a measure of adiposity, were mostly linked to insulin sensitivity and not to insulin resistance in Sudanese type 2 diabetic subjects, where race specific regulation mechanisms or different type 2 diabetes phenotype suggested being a major contributory factor in clarification the findings of this study.

This article is from Physiological Reports , volume 1 . Abstract Prolonged food deprivation increases lipid oxidation and utilization, which may contribute to the onset of the insulin resistance associated with fasting. Because insulin resistance promotes the preservation of glucose and oxidation of fat, it has been suggested to be an adaptive response to food deprivation. However, fasting mammals exhibit hypoinsulinemia, suggesting that the insulin resistance-like conditions they experience may actually result from reduced pancreatic sensitivity to glucose/capacity to secrete insulin. To determine whether fasting results in insulin resistance or in pancreatic dysfunction, we infused early- and late-fasted seals (naturally adapted to prolonged fasting) with insulin (0.065 U/kg), and a separate group of late-fasted seals with low (10 pmol/L per kg) or high (100 pmol/L per kg) dosages of glucagon-like peptide-1 (GLP-1) immediately following a glucose bolus (0.5 g/kg), and measured the systemic and cellular responses. Because GLP-1 facilitates glucose-stimulated insulin secretion, these infusions provide a method to assess pancreatic insulin-secreting capacity. Insulin infusions increased the phosphorylation of insulin receptor and Akt in adipose and muscle of early- and late-fasted seals; however, the timing of the signaling response was blunted in adipose of late-fasted seals. Despite the dose-dependent increases in insulin and increased glucose clearance (high dose), both GLP-1 dosages produced increases in plasma cortisol and glucagon, which may have contributed to the glucogenic role of GLP-1. Results suggest that fasting induces adipose-specific insulin resistance in elephant seal pups, while maintaining skeletal muscle insulin sensitivity, and therefore suggests that the onset of insulin resistance in fasting mammals is an evolved response to cope with prolonged food deprivation.

This article is from Drug Design, Development and Therapy , volume 7 . Abstract Background: Insulin-like growth factor II (IGF-II) is a fetal growth protein and an important proangiogenic factor controlled by four promoters (P), of which P2–P4 are inactive in the adult liver. Reactivation and dysregulation of IGF-IIP3 in particular is associated with the attenuation of apoptosis and increased proliferation in a number of liver cancer cell types. Its involvement in experimental liver carcinogenesis makes it a potential target for cancer gene therapy. We designed two IGF-IIP3 specific DNAzymes (DRz1 and DRz2) that target IGF-IIP3 messenger RNA (mRNA) with the aim of reducing IGF-II expression through promoter 3. Methods: IGF-IIP3 mRNA and protein expression levels were assessed using real-time polymerase chain reaction and gel electrophoresis/western blotting after transfection with Lipofectamine® in SMMC-7721, Huh7, and HepG2 cell lines. Cell proliferation was determined via MTT assay; apoptosis was evaluated by fluorescence microscopy and with flow cytometry; procaspase-3 and -9 expression were detected via western blotting; and caspase activity was assayed colorimetrically. Standard procedures were used to calculate means and standard deviations, and P-values below 0.05 were considered to indicate significant differences. Results: DRzs were transfected into hepatocellular carcinoma cells and the results showed that DRz1, in particular, could decrease the expression of IGF-IIP3 by nearly 50%. Furthermore, DRz1 significantly inhibited cell proliferation and induced apoptosis. In addition, the down-regulation of IGF-IIP3 expression was associated with increased caspase-3 and -9 activity in SMMC-7721 cells after 24 hours of transfection. In all experiments, the efficacy of DRz2 to influence IGF-IIP3 levels and associated effects remained second to DRz1. Conclusion: Overall, these results suggest that DRz1-based targeting of IGF-IIP3 mRNA might have antitumorigenic activity and may potentially provide the basis for a novel therapeutic intervention in liver cancer treatment, although further development is required.

This article is from Diabetology & Metabolic Syndrome , volume 6 . Abstract Background: Combination therapy consisting of basal insulin and oral hypoglycemic agents (OHAs) is effective for the treatment of type 2 diabetes (T2DM) that cannot be adequately controlled using OHAs alone. Though basal insulin with metformin or sulfonylurea is an effective therapy, it cannot reduce postprandial glycemia without the risk of hypoglycemia. We examined a two-step regimen consisting of the addition of postprandial hypoglycemic agents (an alpha-glucosidase inhibitor and a glinide) in patients whose T2DM was poorly controlled using basal insulin therapy. Methods: Inpatients between the ages of 30–79 years who had T2DM and an HbA1c level of more than 7.0% were recruited. The patients were treated with once-daily insulin glargine with or without metformin, depending on the patient’s age and renal function. Insulin glargine was titrated to achieve a target fasting glucose level of 70–130 mg/dL as a first step (STEP0). If the 2-hour postprandial glucose (PBG) level was higher than the target of 180 mg/dL, miglitol treatment (150 mg/day) was initiated, with dose adjustments (75–225 mg) allowed depending on abdominal symptoms and the PBG (STEP1). If the PBG of the patients remained higher than the target after 3 days of treatment, mitiglinide (30 mg/day, titrated up to 60 mg) was added (STEP2). We then evaluated the proportion of patients who achieved the target PBG before and after the two-step regimen. Continuous Glucose Monitoring (CGM) was performed throughout the two-step protocol in most of the patients. Results: Of the 16 patients who were recruited (median age, 67.0 [58.0-71.0] years; body mass index, 25.0 [22.0-27.9] kg/m2; HbA1c level at admission, 9.1% [8.35-10.4%]), 1 patient (6.25%) achieved the target PBG at STEP 0 and 14 patients (87.5%) had achieved the target PBG at the end of the treatment protocol (P = 0.002). CGM showed a significant decrease in the glucose level at each step of the protocol. The standard deviations in the CGM glucose levels for 24 hours, MAGE, and M-value also improved. Conclusions: The two-step addition of postprandial hypoglycemic agents to basal insulin therapy is potentially effective and safe for decreasing both the fasting and postprandial glucose levels.

This article is from PLoS ONE , volume 9 . Abstract Background: The trend of lung cancer incidence in Taiwan is unknown, and the association between type 2 diabetes/insulin use and lung cancer is rarely studied. Methods: The trends of lung cancer incidence in 1979–2007 in the Taiwanese general population were calculated. A random sample of 1,000,000 subjects covered by the National Health Insurance in 2005 was recruited. A total of 494,002 men and 502,948 women and without lung cancer were followed for the annual cumulative incidence of lung cancer in 2005, with calculation of the risk ratios between diabetic and non-diabetic subjects. Logistic regression estimated the adjusted odds ratios for risk factors. Results: The trends increased significantly in both sexes (P

This article is from Journal of Neuroinflammation , volume 10 . Abstract Background: Recent studies in experimental animals show that insulin-like growth factor 1 (IGF1) plays a trophic role during development and tissue injury and that microglia are important sources of IGF1. However, little information is available regarding the expression, regulation, and function of IGF1 and related proteins in human brain cells. In the current study, we examined the expression of IGF1 and IGF2 in human microglia in vivo and in vitro. Methods: Expression of IGF1 and IGF2 was examined by immunohistochemistry in post-mortem human brain sections derived from HIV+ and HIV− brains. In primary cultures of human fetal microglia, IGF1 and IGF2 mRNA and protein expression was examined by Q-PCR, ELISA, and Western blot analysis. Additionally, the role of IGF1 and IGF2 in neuroprotection was examined in primary human neuronal glial cultures. Results: Immunohistochemistry of human brain tissues showed that nonparenchymal cells (vessels and meninges), as well as parenchymal microglia and macrophages were positive for IGF1, in both HIV encephalitis and control brains, while IGF2 was undetectable. Cultured microglia expressed IGF1 mRNA and produced pg/ml levels of IGF1 protein; this was significantly suppressed by proinflammatory mediators, such as lipopolysaccharide (LPS), poly(I:C), and IFNγ. The Th2 cytokines IL-4 and IL-13 had no significant effect, but the cAMP analog (dibutyryl cAMP) significantly increased IGF1 production. In contrast, microglial IGF2 mRNA and protein (determined by Western blot) were upregulated by LPS. IGF1 receptor (IGF1R) immunoreactivity was predominantly expressed by neurons, and both IGF1 and IGF2 significantly protected neurons from cytokine (IL-1/IFNγ) induced death. Conclusions: Our study in human brain tissues and cells indicates that microglia are important sources of neurotrophic growth factors IGF1 and IGF2, and that microglial activation phenotypes can influence the growth factor expression. Importantly, our results suggest that chronic neuroinflammation and upregulation of proinflammatory cytokines could lead to neurodegeneration by suppressing the production of microglia-derived neuronal growth factors, such as IGF1.

This article is from Diabetes , volume 62 . Abstract Elevated fasting blood glucose (FBG) is associated with increased risk for the development of type 2 diabetes and cardiovascular-associated mortality. Genome-wide association studies (GWAS) have linked polymorphisms in G6PC2 with variations in FBG and body fat, although not insulin sensitivity or glucose tolerance. G6PC2 encodes an islet-specific, endoplasmic reticulum–resident glucose-6-phosphatase catalytic subunit. A combination of in situ perfused pancreas, in vitro isolated islet, and in vivo analyses were used to explore the function of G6pc2 in mice. G6pc2 deletion had little effect on insulin sensitivity and glucose tolerance, whereas body fat was reduced in female G6pc2 knockout (KO) mice on both a chow and high-fat diet, observations that are all consistent with human GWAS data. G6pc2 deletion resulted in a leftward shift in the dose-response curve for glucose-stimulated insulin secretion (GSIS). As a consequence, under fasting conditions in which plasma insulin levels were identical, blood glucose levels were reduced in G6pc2 KO mice, again consistent with human GWAS data. Glucose-6-phosphatase activity was reduced, whereas basal cytoplasmic calcium levels were elevated in islets isolated from G6pc2 KO mice. These data suggest that G6pc2 represents a novel, negative regulator of basal GSIS that acts by hydrolyzing glucose-6-phosphate, thereby reducing glycolytic flux.

This article is from Experimental & Molecular Medicine , volume 45 . Abstract Glucagon-like peptide-1 (GLP-1) is a potent glucoincretin hormone and an important agent for the treatment of type 2 diabetes. Here we demonstrate that B-cell translocation gene 2 (BTG2) is a crucial regulator in GLP-1-induced insulin gene expression and insulin secretion via upregulation of pancreatic duodenal homeobox-1 (PDX-1) in pancreatic β-cells. GLP-1 treatment significantly increased BTG2, PDX-1 and insulin gene expression in pancreatic β-cells. Notably, adenovirus-mediated overexpression of BTG2 significantly elevated insulin secretion, as well as insulin and PDX-1 gene expression. Physical interaction studies showed that BTG2 is associated with increased PDX-1 occupancy on the insulin gene promoter via a direct interaction with PDX-1. Exendin-4 (Ex-4), a GLP-1 agonist, and GLP-1 in pancreatic β-cells increased insulin secretion through the BTG2–PDX-1–insulin pathway, which was blocked by endogenous BTG2 knockdown using a BTG2 small interfering RNA knockdown system. Finally, we revealed that Ex-4 and GLP-1 significantly elevated insulin secretion via upregulation of the BTG2–PDX-1 axis in pancreatic islets, and this phenomenon was abolished by endogenous BTG2 knockdown. Collectively, our current study provides a novel molecular mechanism by which GLP-1 positively regulates insulin gene expression via BTG2, suggesting that BTG2 has a key function in insulin secretion in pancreatic β-cells.

This article is from Diabetes , volume 62 . Abstract Krüppel-like factor 3 (KLF3) is a transcriptional regulator that we have shown to be involved in the regulation of adipogenesis in vitro. Here, we report that KLF3-null mice are lean and protected from diet-induced obesity and glucose intolerance. On a chow diet, plasma levels of leptin are decreased, and adiponectin is increased. Despite significant reductions in body weight and adiposity, wild-type and knockout animals show equivalent energy intake, expenditure, and excretion. To investigate the molecular events underlying these observations, we used microarray analysis to compare gene expression in Klf3+/+ and Klf3−/− tissues. We found that mRNA expression of Fam132a, which encodes a newly identified insulin-sensitizing adipokine, adipolin, is significantly upregulated in the absence of KLF3. We confirmed that KLF3 binds the Fam132a promoter in vitro and in vivo and that this leads to repression of promoter activity. Further, plasma adipolin levels were significantly increased in Klf3−/− mice compared with wild-type littermates. Boosting levels of adipolin via targeting of KLF3 offers a novel potential therapeutic strategy for the treatment of insulin resistance.

This article is from Frontiers in Physiology , volume 4 . Abstract The insulin/insulin-like growth factor signaling (IIS) pathway is well-established as a critical regulator of growth and metabolic homeostasis across the animal kingdom. Insulin-like peptides (ILPs), the functional analogs of mammalian insulin, were initially discovered in the silkmoth Bombyx mori and subsequently identified in many other insect species. Initial research focused on the role of insulin signaling in metabolism, cell proliferation, development, reproduction and aging. More recently however, increasing attention has been given to the role of insulin in the regulation of neuronal function and behavior. Here we review the role of insulin signaling in two specific insect behaviors: feeding and locomotion.

This article is from Breast Cancer Research : BCR , volume 13 . Abstract Introduction: Recently we reported that insulin receptor substrate 1 (IRS-1), classically an adaptor protein for the insulin-like growth factor type I receptor (IGF-IR), associates with the epidermal growth factor receptor in oestrogen receptor (ER)-positive (ER+) tamoxifen-resistant breast cancer cells. In this study, we examined whether IRS-1 also associates with another erbB receptor family member, erbB3, and what impact this might have on IGF-IR signalling in three ER+ breast cancer cell lines. Methods: Immunoprecipitation and Western blot analysis were utilised to examine the potential association between erbB3 and IRS-1 in MCF-7, T47D and BT-474 cells in the absence and presence of the erbB3/4 ligand heregulin β1 (HRGβ1). Subsequently, the impact of a selective IGF-IR/IR inhibitor 4-anilino-5-bromo-2-[4-(2-hydroxy-3-(N, N-dimethylamino)propoxy)anilino]pyrimidine on this association and HRGβ1 signalling was assessed in these cell lines. Immunohistochemical analysis of a small cohort of ER+ breast cancer patient samples was also performed to determine the potential clinical relevance of this novel interaction. Results: Immunoprecipitation and Western blot analysis revealed an interaction between erbB3 and IRS-1 in MCF-7, T47D and BT-474 cells, with HRGβ1 significantly enhancing this recruitment and promoting IRS-1 phosphorylation at Y612. IRS-1 participates in erbB3 signalling in MCF-7 and T47D cells as IRS-1 knockdown impaired HRGβ1 signalling. Importantly, recruitment of IRS-1 by erbB3 reduced IRS-1 association with IGF-IR in MCF-7 and T47D cells, whilst blockade of IGF-IR-enhanced erbB3-IRS-1 interaction and sensitised both cell lines to HRGβ1, allowing HRGβ1 to override IGF-IR blockade. Consequently, suppression of IRS-1 signalling enhanced the effects of IGF-IR inhibition in these cells. This novel interaction may have clinical relevance, as immunohistochemical analysis of a small ER+ breast tumour series revealed significant positive correlations between phosphorylated IRS-1 Y612 expression and total erbB3, phosphorylated Akt and Ki-67 expression. Conclusions: IRS-1 can be recruited to IGF-IR and erbB3 in ER+ breast cancer cells, and this provides an adaptive resistance mechanism when these receptors are targeted individually. Consequently, cotargeting IGF-IR and either erbB3 or IRS-1 should prove to be a more effective strategy for the treatment of ER+ breast cancer.

This article is from Nutrition & Metabolism , volume 8 . Abstract Background: Diets high in cereal-fiber (HCF) have been shown to improve whole-body insulin sensitivity. In search for potential mechanisms we hypothesized that a supplemented HCF-diet influences the composition of the human gut microbiota and/or biomarkers of colonic carbohydrate fermentation. Methods: We performed a randomized controlled 18-week intervention in group-matched overweight participants. Fecal samples of 69 participants receiving isoenergetic HCF (cereal-fiber 43 g/day), or control (cereal-fiber 14 g/day), or high-protein (HP, 28% of energy-intake, cereal-fiber 14 g/day), or moderately high cereal fiber/protein diets (MIX; protein 23% of energy-intake, cereal-fiber 26 g/day) with comparable fat contents were investigated for diet-induced changes of dominant groups of the gut microbiota, and of fecal short-chain fatty-acids (SCFA) including several of their proposed targets, after 0, 6, and 18-weeks of dietary intervention. In vitro fermentation of the cereal fiber extracts as used in the HCF and MIX diets was analyzed using gas chromatography. Diet-induced effects on whole-body insulin-sensitivity were measured using euglycaemic-hyperinsulinemic clamps and re-calculated in the here investigated subset of n = 69 participants that provided sufficient fecal samples on all study days. Results: Gut microbiota groups and biomarkers of colonic fermentation were comparable between groups at baseline (week 0). No diet-induced differences were detected between groups during this isoenergetic intervention, neither in the full model nor in uncorrected subgroup-analyses. The cereal-fiber extract as used for preparation of the supplements in the HCF and MIX groups did not support in vitro fermentation. Fecal acetate, propionate, and butyrate concentrations remained unchanged, as well as potential targets of increased SCFA, whereas valerate increased after 6-weeks in the HP-group only (p = 0.037). Insulin-sensitivity significantly increased in the HCF-group from week-6 (baseline M-value 3.8 ± 0.4 vs 4.3 ± 0.4 mg·kg-1·min-1, p = 0.015; full model 0-18-weeks, treatment-x-time interaction, p = 0.046). Conclusions: Changes in the composition of the gut microbiota and/or markers of colonic carbohydrate fermentation did not contribute explaining the observed early onset and significant improvement of whole-body insulin sensitivity with the here investigated HCF-diet. Trial registration: This trial was registered at http://www.clinicaltrials.gov as NCT00579657

This article is from Diabetes , volume 61 . Abstract : Cerebral insulin exerts anorexic effects in humans and animals. The underlying mechanisms, however, are not clear. Because insulin physiologically facilitates glucose uptake by most tissues of the body and thereby fosters intracellular energy supply, we hypothesized that intranasal insulin reduces food consumption via enhancement of the neuroenergetic level. In a double-blind, placebo–controlled, within-subject comparison, 15 healthy men (BMI 22.2 ± 0.37 kg/m2) aged 22–28 years were intranasally administered insulin (40 IU) or placebo after an overnight fast. Cerebral energy metabolism was assessed by 31P magnetic resonance spectroscopy. At 100 min after spray administration, participants consumed ad libitum from a test buffet. Our data show that intranasal insulin increases brain energy (i.e., adenosine triphosphate and phosphocreatine levels). Cerebral energy content correlates inversely with subsequent calorie intake in the control condition. Moreover, the neuroenergetic rise upon insulin administration correlates with the consecutive reduction in free-choice calorie consumption. Brain energy levels may therefore constitute a predictive value for food intake. Given that the brain synchronizes food intake behavior in dependence of its current energetic status, a future challenge in obesity treatment may be to therapeutically influence cerebral energy homeostasis. Intranasal insulin, after optimizing its application schema, seems a promising option in this regard.

This article is from Gut , volume 61 . Abstract Background: Obesity is associated with accumulation of macrophages in white adipose tissue (WAT), which contribute to the development of insulin resistance. Germ-free (GF) mice have reduced adiposity and are protected against diet-induced obesity, Objective: To investigate whether the gut microbiota and, specifically, gut-derived lipopolysaccharide (LPS) promote WAT inflammation and contribute to impaired glucose metabolism. Method: Macrophage composition and expression of proinflammatory and anti-inflammatory markers were compared in WAT of GF, conventionally raised and Escherichia coli-monocolonised mice. Additionally, glucose and insulin tolerance in these mice was determined. Results: The presence of a gut microbiota resulted in impaired glucose metabolism and increased macrophage accumulation and polarisation towards the proinflammatory M1 phenotype in WAT. Monocolonisation of GF mice for 4 weeks with E.coli W3110 or the isogenic strain MLK1067 (which expresses LPS with reduced immunogenicity) resulted in impaired glucose and insulin tolerance and promoted M1 polarisation of CD11b cells in WAT. However, colonisation with E.coli W3110 but not MLK1067 promoted macrophage accumulation and upregulation of proinflammatory and anti-inflammatory gene expression as well as JNK phosphorylation. Conclusion: Gut microbiota induced LPS-dependent macrophage accumulation in WAT, whereas impairment of systemic glucose metabolism was not dependent on LPS. These results indicate that macrophage accumulation in WAT does not always correlate with impaired glucose metabolism.

This article is from Journal of Neuroinflammation , volume 11 . Abstract Background: Inhibition of TNFα protects the retina against diabetic-like changes in rodent models. The mechanism by which TNFα induces deleterious retinal changes is not known. Previously, we have shown that TNFα can inhibit normal insulin signal transduction, leading to increased apoptosis in both retinal endothelial cells (REC) and Müller cells. Additionally, β2-adrenergic receptor knockout mice (β2KO) have increased TNFα levels and decreased insulin receptor activity. In this study, we hypothesized that inhibition of TNFα in β2KO mice would increase normal insulin signaling, leading to improved retinal function. Methods: C57BL6 or β2KO mice were left untreated or treated with etanercept (0.3 mg/kg subcutaneously, 3× a week) for 2 months. Electroretinogram analyses were done before treatment was initiated and after two months of treatment with etanercept on all mice. Western blot or ELISA analyses were done on whole retinal lysates from all four groups of mice for TNFα, suppressor of cytokine signaling 3 (SOCS3), insulin receptor, and apoptotic proteins. Results: Etanercept significantly reduced TNFα levels in β2KO mice, leading to increased insulin receptor phosphorylation on tyrosine 1150/1151. SOCS3 levels were increased in β2KO mice, which were reduced after etanercept treatment. Pro-apoptotic proteins were reduced in etanercept-treated β2KO mice. Etanercept improved ERG amplitudes in β2KO mice. Conclusions: Inhibition of TNFα by etanercept protects the retina likely through reduced TNFα-mediated insulin resistance, leading to reduced apoptosis.

This article is from Iranian Journal of Reproductive Medicine , volume 10 . Abstract Background: Polycystic ovary syndrome (PCOS) is the most common endocrine disorder in females of reproductive age. Insulin resistance is a frequent metabolic disturbance in PCOS. Vitamin D deficiency is a common problem. Accumulating evidence suggests that vitamin D has a role on insulin sensitivity so may contribute to reduction of hyperandrogenemia.Objective: The aim was to determine the effects of vitamin D treatment in metabolic components and ovulation evidence in PCOS.Materials and Methods: Fifty one untreated PCOS patients were randomly divided into three groups and treated with calcitriol, metformin, or placebo. Before and 3 months after treatment, ovulation evidence was assessed by ovarian trans abdominal sonography. Plasma fasting glucose, insulin, homeostasis model assessment insulin resistance (HOMA-IR), 25-hydroxyvitamin D, parathyroid hormone and androgen levels were measured before and after treatment. A 75gr glucose test was performed before and after treatment and two set of results was compared.Results: Three patients did not continue this study. Only 11 patient (22.9%) had sufficient vitamin D levels (>30 ng/ml). Metformin caused a significant decrease in weight (p=0.027), insulin level (p=0.043), and insulin resistance (p=0.048). Systolic blood pressure and PTH significantly improved after calcitriol (p=0.029, p=0.009 respectively). An improvement in ovulation was detected after calcitriol and seven patients, without evidence of ovulation before treatment, illustrated ovulation after 3 months. Difference with calcitriol in ovulation was significant versus other two methods (p=0.02).Conclusion: Calcitriol treatment in PCOS may be prior to metformin in ovulation induction.

This article is from Pakistan Journal of Medical Sciences , volume 30 . Abstract Objective: To assess inpatient management of non-critically ill type 2 diabetics with different insulin regimen.Methods: We reviewed the medical records of all non-critically ill type 2 diabetic patients more than 18 years of age in medical department of civil hospital Karachi and Dow University of Health Sciences from January 2011 to December 2012. We collected the data from case records in data collection sheets that fulfill the inclusion criteria and divided the study subjects into three groups according to insulin regimen they received.Results: A total of 416 patients were analyzed out of which 220 were male. Subjects were divided into three groups according to insulin regimen they received. Majority were put on sliding scale of insulin (44.7%), while 33.1% and 22.1% subjects received basal bolus and pre-mixed insulin regimen respectively. Patients treated with basal bolus regimen had greater improvement in glycaemic control with short duration of hospital stay as compared to other two groups. The mean hyperglycaemic events were higher in sliding scale group while mean hypoglycaemic events were higher in basal bolus group.Conclusion: In non-critically ill type 2 diabetic patients the basal bolus regimen is superior to sliding and pre-mixed insulin regimen. Sliding scale should be discouraged in non-critically ill type 2 diabetic patients.

This article is from PLoS ONE , volume 9 . Abstract Estrogen influences memory formation and insulin sensitivity. Meanwhile, glucose utilization directly affects learning and memory, which are modulated by insulin signals. Therefore, this study investigated whether or not the effect of estrogen on memory is associated with the regulatory effect of this hormone on glucose metabolism. The relative expression of estrogen receptor β (ERβ) and glucose transporter type 4 (GLUT4) in the hippocampus of rats were evaluated by western blot. Insulin level was assessed by ELISA and quantitative RT-PCR, and spatial memory was tested by the Morris water maze. Glucose utilization in the hippocampus was measured by 2-NBDG uptake analysis. Results showed that ovariectomy impaired the spatial memory of rats. These impairments are similar as the female rats treated with the ERβ antagonist tamoxifen (TAM). Estrogen blockade by ovariectomy or TAM treatment obviously decreased glucose utilization. This phenomenon was accompanied by decreased insulin level and GLUT4 expression in the hippocampus. The female rats were neutralized with hippocampal insulin with insulin antibody, which also impaired memory and local glucose consumption. These results indicated that estrogen blockade impaired the spatial memory of the female rats. The mechanisms by which estrogen blockade impaired memory partially contributed to the decline in hippocampal insulin signals, which diminished glucose consumption.

This article is from Journal of Nutritional Science , volume 2 . Abstract The effects of Enzamin on obesity-related metabolic disorders in obese db/db mice were examined to explore a novel agent for the prevention of insulin resistance. Db/db mice were treated with water containing Enzamin (0·1 and 1·0 %) for 8 weeks from 6 weeks of age. Enzamin treatment at 1·0 %, but not at 0·1 %, significantly decreased the fasting plasma glucose, serum total cholesterol and TAG levels in db/db mice, without affecting body weight gain and body fat composition. Furthermore, insulin sensitivity and glucose tolerance were improved by the treatment of db/db mice with 1·0 % Enzamin. Immunohistochemical studies and gene expression analysis showed that 1·0 % Enzamin treatment suppressed macrophage accumulation and inflammation in the adipose tissue. In addition, 1·0 % Enzamin treatment increased serum adiponectin in db/db mice. Treatment with 1·0 % Enzamin also significantly suppressed the expression of NADPH oxidase subunits, suggesting an antioxidative effect for Enzamin in the adipose tissue. Furthermore, in vitro experiments demonstrated that the lipopolysaccharide-induced inflammatory reaction was significantly suppressed by Enzamin treatment in macrophages. Enzamin treatment increased the expression of GLUT4 mRNA in muscle, but not GLUT2 mRNA in the liver of db/db mice. Enzamin also increased the mRNA expression of carnitine palmitoyltransferase 1a (CPT1a, muscle isoform) in db/db mice, whereas Enzamin treatment did not affect the mRNA expression of CPT1b (liver isoform) in db/db mice. In conclusion, our data indicate that Enzamin can improve insulin resistance by ameliorating impaired adipocytokine expression, presumably through its anti-inflammatory action, and that Enzamin possesses a potential for preventing the metabolic syndrome.

This article is from BMJ Open , volume 4 . Abstract Introduction: Despite therapeutic advances, many people with type 1 diabetes are still unable to achieve optimal glycaemic control, limited by the occurrence of hypoglycaemia. The objective of the present study is to determine the effectiveness of day and night home closed-loop over the medium term compared with sensor-augmented pump therapy in adults with type 1 diabetes and suboptimal glycaemic control. Methods and analysis: The study will adopt an open label, three-centre, multinational, randomised, two-period crossover study design comparing automated closed-loop glucose control with sensor augmented insulin pump therapy. The study will aim for 30 completed participants. Eligible participants will be adults (≥18 years) with type 1 diabetes treated with insulin pump therapy and suboptimal glycaemic control (glycated haemoglobin (HbA1c) ≥7.5% (58 mmol/mmol) and ≤10% (86 mmol/mmol)). Following a 4-week optimisation period, participants will undergo a 3-month use of automated closed-loop insulin delivery and sensor-augmented pump therapy, with a 4–6 week washout period in between. The order of the interventions will be random. All analysis will be conducted on an intention to treat basis. The primary outcome is the time spent in the target glucose range from 3.9 to 10.0 mmol/L based on continuous glucose monitoring levels during the 3 months free living phase. Secondary outcomes include HbA1c changes; mean glucose and time spent above and below target glucose levels. Further, participants will be invited at baseline, midpoint and study end to participate in semistructured interviews and complete questionnaires to explore usability and acceptance of the technology, impact on quality of life and fear of hypoglycaemia. Ethics and dissemination: Ethical approval has been obtained at all sites. Before screening, all participants will be provided with oral and written information about the trial. The study will be disseminated by peer-review publications and conference presentations. Trial registration number: NCT01961622 (ClinicalTrials.gov).

This article is from PLoS ONE , volume 9 . Abstract Objective: Insulin-like growth factor-1 (IGF-1) has been associated with cardiovascular risk factors and atherosclerosis. The aim of the present study was to evaluate the prognostic value of IGF-1 levels in patients with acute ischemic stroke (AIS). Methods: All patients with first-ever AIS from August 1, 2012 to August 31, 2013 were recruited to participate in the study. Clinical data were collected. The National Institutes of Health Stroke Scale (NIHSS) score was assessed on admission blinded to serum IGF-1 levels. For the assessment of functional outcome at 90 days Modified Rankin Scale (mRS) was used. On admission, serum IGF-1 levels were determined by chemiluminescence immunoassay. The influence of IGF-1 levels on functional outcome and death was assessed by multivariate logistic regression analysis. Results: Patients with an unfavorable outcomes and non-survivors had significantly decreased serum IGF-1 levels on admission (P

This article is from Patient preference and adherence , volume 8 . Abstract Background: Self-monitoring of blood glucose (SMBG) helps to improve glycemic control and empowerment of people with diabetes. It is particularly useful for people with diabetes who are using insulin as it facilitates insulin titration and detection of hypoglycemia. Despite this, the uptake of SMBG remains low in many countries, including Malaysia. Purpose: This study aimed to explore the barriers and facilitators to SMBG, in people with type 2 diabetes using insulin. Patients and methods: Qualitative methodology was employed to explore participants’ experience with SMBG. Semistructured, individual in-depth interviews were conducted on people with type 2 diabetes using insulin who had practiced SMBG, in the primary care clinic of a teaching hospital in Malaysia. Participants were purposively sampled from different age groups, ethnicity, education level, and level of glycemic control (as reflected by the glycated hemoglobin [HbA1c]), to achieve maximum variation in sampling. All interviews were conducted using a topic guide and were audio-recorded, transcribed verbatim, checked, and analyzed using a thematic approach. Results: A total of 15 participants were interviewed, and thematic saturation was reached. The factors that influenced SMBG were mainly related to cost, participants’ emotion, and the SMBG process. The barriers identified included: frustration related to high blood glucose reading; perception that SMBG was only for insulin titration; stigma; fear of needles and pain; cost of test strips and needles; inconvenience; unconducive workplace; and lack of motivation, knowledge, and self-efficacy. The facilitators were: experiencing hypoglycemic symptoms; desire to see the effects of dietary changes; desire to please the physician; and family motivation. Conclusion: Participants’ perceptions of the purpose of SMBG, the emotions associated with SMBG, and the complexity, pain, and cost related to SMBG as well as personal and family motivation are the key factors that health care providers must consider when advising people with diabetes on SMBG.

This article is from Journal of Diabetes and Metabolic Disorders , volume 13 . Abstract Background: Intensive insulin therapy is essential in the maintenance of strict glycemic control among insulin requiring patients with diabetes. However this presents a challenge in the face of the complexities associated with insulin use and also taking into consideration the potential dangers associated with inappropriate use. Insufficient knowledge of insulin use can result in preventable complications, adverse patient outcome, poor adherence to therapy and invariably poor glycemic control. Methods: Insulin requiring diabetes patients (n = 54) attending the 2012 world diabetes day celebration in a Nigerian community were surveyed using a two part questionnaire. Section A elicited information on their demographics characteristics and participation in update courses, and exercise, while section B assessed knowledge of insulin use using the Michigan Diabetes Research and Training Centre's Brief Diabetes Knowledge Test. All participants who had a good grasp of English language or who could understand the contents of the questionnaire when it was explained to them, and were willing to participate in the study were assessed. Descriptive statistics of percentages was computed for the sociodemographic variables, previous education, satisfaction with education, involvement in regular exercise, knowledge of benefit of exercise and correct response to each question in section B. Analysis of variance (ANOVA) and independent t-test was used to determine the influence of sociodemographic variables on insulin use knowledge. Results: Knowledge of insulin use is poor among insulin requiring patients with diabetes, with majority not conversant with such terms as ketoacidosis, insulin reaction and low blood sugar. Furthermore, they did not know how to modify their insulin dosage in relation to diet, exercise and infections (e.g. flu). Better knowledge of insulin use was associated with age, employment status, level of education attained, how frequent one reads/attends update courses and satisfaction with education received. Conclusion: Poor knowledge of the causes and prevention of the ketoacidosis, insulin reaction and hypoglycemia increases their risk of developing them, which will invariably lead to poor adherence to insulin therapy. Therefore this study suggests a methodical, continuous and up-to-date tutelage if proper self management in terms of good glycemic control is to be achieved.

This article is from Diabetology & Metabolic Syndrome , volume 6 . Abstract Aim: Premixed insulin regimens are commonly used for the treatment of patients with type-2 diabetes mellitus (T2DM). However, limited data are available regarding next-step therapy options in cases where premixed insulin fails to provide adequate glycemic control. This 20-week observational study of everyday clinical practice evaluated the efficacy, safety and treatment satisfaction of insulin glargine plus oral anti-diabetic drugs (OADs) in T2DM patients previously treated with premixed insulin. Methods: In this open-label, single-arm, 20-week study, 70 subjects with T2DM inadequately controlled with premixed insulin were switched to insulin glargine plus OADs. Changes in glycaemic control, incidence of hypoglycaemia, treatment satisfaction using the Diabetes Treatment Satisfaction Questionnaire (DTSQ), serum superoxide dismutase (SOD), and serum 8-iso-prostaglandin (8-iso-PG) were evaluated at the start and the end of the study. Results: Over the 20 week treatment period, mean (±SD) HbA1c levels decreased from 8.28 ± 1.24% to 6.83 ± 1.09%, mean (±SD) FBG levels decreased from 7.64 ± 1.36 mmol/L to 5.57 ± 1.21 mmol/L, and 2 h PBG levels decreased from 12.07 ± 1.17 mmol/L to 8.94 ± 1.56 mmol/L, all P

This article is from Open Medicine , volume 2 . Abstract Background: Although evidence-based guidelines for the treatment of type 2 diabetes mellitus provide clear recommendations for initial therapy, evidence on an optimal treatment strategy after secondary failure is unclear. Purpose: To compare the efficacy of add-on therapy using basal insulin versus an additional oral antidiabetic agent in patients with type 2 diabetes and secondary failure. Data sources: We searched the following electronic databases from inception until June 2007: MEDLINE; EMBASE; Cochrane Central Register of Controlled Trials; Web of Science; Scopus; CINAHL; International Pharmaceutical Abstracts; Academic OneFile; PASCAL; Global Health Database; LILACS; HealthSTAR; PubMed. Reference lists of potentially relevant articles and clinical trial databases were searched, pharmaceutical manufacturers were contacted, and grey literature sources were sought. Study selection: Randomized controlled trials (RCTs) involving subjects with type 2 diabetes with secondary failure who were randomly assigned to receive additional basal insulin therapy (insulin glargine, detemir, or NPH [neutral protamine Hagedorn]) versus another oral antidiabetic agent from any class. Data extraction: Two reviewers independently screened articles, extracted data and assessed methodological quality. Our primary outcome was glycemic control measured by change in glycosylated hemoglobin (HbA1C) and the proportion of subjects achieving a HbA1C value of ≤ 7%. Data synthesis: To compare overall efficacy between the 2 treatment strategies, change in HbA1C was pooled across studies using a random-effects model and weighted mean difference (WMD). Eleven RCTs, involving 757 participants with a median age of 56 and a median known duration of diabetes of 11 years, were included in our analysis. Insulin treatment demonstrated a small but statistically significant improvement in HbA1C compared with the use of an additional oral agent as add-on therapy (WMD -0.17; 95% CI [confidence interval] -0.33 to -0.02). Limitations: The use of surrogate outcomes and the short duration of the trials makes it impossible to gain information on long-term patient-oriented outcomes. The overall quality of the studies was low, primarily in view of inadequate blinding. Conclusions: Although add-on therapy using injected insulin shows a slight benefit over an additional oral antidiabetic agent, our results indicate that basal insulin therapy and the use of an oral agent as add-on therapy produce comparable results. Non-therapeutic differences must be considered in the choice of treatment strategies. More high-quality studies with adequate safety data using more aggressive insulin titrations are needed.
