Ozempic Creator Targets Alzheimer's Breakthrough
[MUSIC] Welcome to quick news. This is Ted. The news was published on Monday, November 4th. Today, we'll be diving into a fascinating article about Dr. Lotta Knudsen, the person behind the rise of a Zempic. Now, she's turning her focus towards finding a cure for Alzheimer's. We've got Eric and Kate here with us. Let's get into it. Sure thing, Ted. Samagletide is a drug initially aimed at treating type 2 diabetes, but now it's become quite famous for weight loss as well. It's a GLP1 analog, which means it mimics a hormone that helps you feel full after eating. What's amazing is that it's got a longer duration of action compared to its predecessors, making a big difference in its efficacy. That's right, Eric. But we can't overlook its possible role in treating Alzheimer's. The article spotlights how studies have shown that semaglutide can also reduce cognitive decline in patients with Alzheimer's. The fact that one drug can address both metabolic and neurodegenerative issues is pretty groundbreaking. Absolutely, it's groundbreaking. However, it's still in the experimental stage. We need more concrete evidence before we start celebrating. The article points out that while its potential exists, the actual effectiveness against Alzheimer's isn't definitive. I completely disagree with the need for skepticism, Eric. Just look at the studies. A 53% lower risk of developing dementia in some of them is no small feat. That's significant enough to give us a lot of hope. Those are very interesting points. Kate, could you explain how GLP1 interacts with the brain and what benefits it might have? Sure thing, Ted. GLP1 interacts with hormones in the brain to control appetite, which is a big part of why it helps with weight loss. But more importantly, for Alzheimer's, it also has a role in improving memory function. This makes it crucial for tackling diseases where cognitive decline is a key symptom. I get that, but we still need to exercise caution here. The article mentions that a lot of current research was mostly focused on beta-amyloid proteins, which might not even be the right target. GLP1 is a fresh angle, and it's not yet widely accepted in the scientific community. Consider this, Eric. We know Type 2 diabetes increases the risk of Alzheimer's by 77%. If this GLP1 approach is something that can combat both conditions, then it could be a game changer in every sense. Eric, let's delve into the potential side effects that were mentioned in the article. What are your thoughts on them? The article does bring up some serious concerns. We're talking about severe gastrointestinal issues like stomach paralysis and gallbladder problems. There's also the problem of not knowing if people will regain weight once they stop taking the drugs since there's no long-term data on this yet. Though side effects are pretty rare when you consider the larger picture, Eric. The benefits of these drugs seem to outweigh the risks, especially when we're dealing with a crisis in Alzheimer's. I hear you, but with a class-action lawsuit in the mix, proclaiming this as the ultimate solution might be a bit premature. We must keep our eyes open for all possible implications before wholeheartedly endorsing it. Solid points from both perspectives. Let's switch gears for a moment and get a historical perspective. Do either of you recall a similar medical breakthrough from the past? Absolutely, Ted. The discovery of insulin in the early 20th century was game-changing for diabetes and some agletide is playing a similar role now. Insulin turned lives around just as we've seen ozempic and wagovi do for folks today. Very true. But we should also remember the lessons learned from early insulin use. It had a bunch of unanticipated side effects that took years for researchers to address and refine the treatment. Exactly which is why we need to tread carefully with semagletide. It's still relatively new. We don't yet know all the long-term impacts and rushing things could lead us into murky waters. But unlike early insulin, which really needed refining over the years, these current GLP-1 drugs such as semagletide already show a lot of promise. They're helping not only with diabetes, but also obesity, heart disease, and now there's a potential for Alzheimer's treatment. So are we walking the same path of initial excitement followed by a period of discovering potential pitfalls? Absolutely, Ted. The comparison is spot-on. Just as with early insulin, we might face unforeseen challenges and side effects with semagletide as well. It's essential to maintain a balanced approach and not only ride the wave of optimism. But unlike insulin, the research-backing GLP-1 drugs has been more thorough before they even hit the mainstream. We've learned from past mistakes, and I think we're better prepared this time to handle. I hope you're right, Kate. Still, even Dr. Knudson acknowledges that the effectiveness against Alzheimer's hasn't been proven in its entirety yet. She did say that, but every groundbreaking treatment meets with skepticism in its early days. If we let that fear hold us back, we'd never advance. Eric, could the history of these medical breakthroughs offer any strategies for the future with semagletide? Definitely, Ted. A key lesson is to ensure thorough long-term studies and adopt cautious optimism. History shows us that rushing through these breakthroughs can end in disaster. And at the same time, Ted, just as with insulin, we need to keep advancing and experimenting. The potential benefits for Alzheimer's patients are too significant to ignore. Excellent debate. Moving to the future implications now. What are two possible paths this research into semagletide might take? One possibility is that semagletide might show effectiveness against Alzheimer's, but with significant side effects. While this could advance treatment for the disease, ongoing risks would remain a concern. Geez, Eric, that's so gloomy. Another possible outcome is that semagletide could not only aid Alzheimer's patients, but emerge as a multi-purpose drug tackling several chronic conditions without severe side effects. Imagine the leap forward, that would be. Those are intriguing possibilities. But what if the research hits roadblocks and doesn't progress as hoped, Eric? Well, if the research fails, it may be because of unforeseen long-term side effects or because the drug isn't as effective as early studies suggested. This could represent a setback, but it may also open doors to new research avenues. Failure is part of science, but I think the groundwork laid by Dr. Knudsen is solid. Even if semagletide doesn't work out, the exploration into GLP-1 analogs might lead to other innovative treatments. Eric, how might regulatory policies impact the development of semagletide? Strict regulations could slow progress, ensuring safety, but delaying potential benefits. Agencies like the FDA need to balance risks with the urgent need for effective Alzheimer's treatments. Regulatory bodies should be flexible and adapt to new insights emerging from studies. Expedited approvals might be necessary for promising treatments under compassionate use cases. Kate, how do you think public perception might shape the future of this research? Public enthusiasm can be a game-changer in driving funding and expediting research. However, there's a risk of backlash if expectations aren't met quickly or if significant issues arise. Public perception is really a double-edged sword. High expectations can boost progress, but when outcomes fall short, it can lead to legal disputes and erode trust, as hinted at by the ongoing lawsuits. Fantastic insights from both of you. Clearly, the journey of semagletide as a potential treatment is complex with many possible outcomes. Thanks for this stimulating discussion on Dr. Knudsen's pioneering work and its future
