The video discusses a new class of drugs called GLP-1 receptor agonists, with semaglutide being a key ingredient absorbed by the body to regulate appetite. These drugs, initially developed for diabetes, have shown significant efficacy in aiding weight loss, making them a game changer in obesity treatment. Celebrities and influencers have amplified interest and demand for these drugs due to their notable success stories.

While these drugs are effective, concerns exist about their long-term safety, high cost, and the potential misuse through off-label prescriptions. Patients may also need to use these drugs indefinitely to maintain weight loss, highlighting affordability and sustainability challenges. Despite the drugs' popularity, their use has been contentious, with safety and ethical considerations at the forefront of discussions.

WeGovy, Ozempic or Mounjaro? How a new wave of weight loss drugs could transform the diet industry

Imagine it's lunchtime, and instead of craving this giant bacon double cheeseburger to feel full, all you needed was this little slider. That's the reality for many patients taking a brand new kind of obesity treatment. When I took my first dose the next two days, I felt this satisfied hunger feeling that I. I don't think I'd ever felt for years. Wow. Is this how a normal person maybe can feel around food? The secret behind Wagavi and its predecessor, Ezempec, is an active ingredient called semaglutide, which belongs to a group of drugs called GLP one receptor agonists. They work by imitating a naturally occurring gut hormone that helps regulate appetite in the brain.

Originally developed to treat diabetes, this class of drugs has taken the pharmaceutical world by storm. They're much more effective than drugs we've had before. They're even more effective than lifestyle modifications on their own. We're getting lots of inquiries. Lots of people are desperate to try. Celebrities like Elon Musk and Jeremy Clarkson have helped fuel the excitement, with Hollywood stars and social media influencers touting the effectiveness of these miracle drugs. I lost so much weight so fast that I was like, oh, my God, this is magic. This is amazing. I'm going to start we govee because I am a plus size individual and I don't want to be plus size anymore, and I want to be healthier. I lost 75 pounds in seven months, and I've had a lot of people asking me, how did I do it? So is there a catch?

Well, the long term consequences of these drugs are not yet known, and they're expensive. Plus, there are concerns about them getting into the wrong hands. But despite these issues, GLP ones could transform diet market. And experts argue the revolution has only just begun. The latest report by the World Health Organization showed that obesity has nearly tripled since 1975 and continues to rise. There are more than 1 billion people clinically obese globally, of whom 650 million are adults, 340 million are adolescents, and 39 million are children. This is why analysts believe the obesity treatment market could reach more than $50 billion by the end of the decade.

Peter Verdault is a pharmaceuticals analyst at Citi. Could you see obesity becoming a $50 billion plus market without making ridiculous assumptions? That is a feasible scenario. These medicines are so powerful, they're already displacing traditional weight loss programs. In March 2023, shares in WW International, formerly known as Weight Watchers, surged over 70% in one day after the diet company announced a $132 million acquisition of sequence a subscription service, connecting patients with providers which can prescribe these new weight loss drugs.

This relatively new drug class was originally developed by danish pharmaceuticals giant Novo Nordisk to treat diabetes, and it's been a monumental achievement in diabetes care. But researchers also noticed that patients taking these drugs were losing significant amounts of weight. GLP one is a gut hormone that you and myself produce, and it has multiple effects around the body, so it signals the pancreas to produce insulin when glucose or blood sugars are high. It sends signals to glp receptors in certain parts of your brain, almost an appetite suppressant, it slows down the emptying of your stomach, so it makes you feel full, so you eat less.

Novo Nordisk originally won approval for ezempec to treat diabetes, then went back to the regulators with more data and got approval for wugovi, a higher dosage version, to treat obesity. Studies have shown that patients taking a weekly injection of wagavi achieved 15% weight loss over a two year period, compared to just 2.6% with a placebo. Us pharma giant Eli Lilly is hoping for even better results with its own version in 2023, sold under the brand Mungjaro. We govee really sort of changed the paradigm because this is a high dose GLP one. It's the same molecule that's in Novo's best selling diabetes product, called Azempic, but it is at a higher dose. And this drug is now really sort of changing the paradigm of obesity treatment. You're getting 1517, approaching 20% weight loss with a weekly injection.

Jackie Bannister has struggled with weight for years, and she isn't alone. The prevalence of obesity in adults from high income countries is the highest of any income group. After reading reports about celebrities losing weight with these new drugs, she decided it was worth a shot. I do think a lot of people just will say you're not disciplined enough, which, you know, fair enough. But when you are genuinely feeling hungry, and that's all your brain can focus on, even though you know you've eaten what should be for the day, that gets hard to ignore.

As with any new drug, patients worry about safety and side effects. Doctor Babak Ashrafi is a general practitioner and clinical lead for service expansion at Zava, a digital healthcare service. What about side effects? Are there any of concern to you? The main ones with this group of drugs are gut related, and a few what we call centrally associated side effects. So the gut related ones are things like nausea, vomiting, occasional abdominal pain. And the centrally acting side effects are things like headache and fatigue. Some of the rarer ones that we ask people to look out for include things like pancreatitis. But on the whole, these drugs are relatively safe.

They don't tend to interact with a lot of other drugs, and that's part of the appeal. LP, one drug class, has been on the market for 15 years. There is a well established safety database, so I think it's a pretty safe drug class for sure. So far, Jackie's tolerated the injections well. I've had no negative side effects, which was something that really scared me to begin with. It seems to be doing the job. I'm not quite on the full dose yet that's to come in the future, but so far I seem to be tolerating it really well.

So how are social media influencers and celebrities getting their hands on these drugs if they're intended for those with diabetes or struggling with obesity? The answer lies in a practice called off label prescriptions. This is when a drug is used for a medical condition that it is not approved to treat or given in a different way or in a different dose than intended. The practice is commonly used in cancer treatment. Jackie has been taking Ozempec off label, as Wagavi was only approved for use in the UK's free healthcare system in 2023.

I have yo yoed so much and ever since taking this I've been consistent, which has been awesome mentally and physically, and it's been working. I've lost weight. As the drugs become more popular, concerns about off label prescriptions are on the rise too. Novo understandably can't stop Elon Musk from sending a tweet out to his followers. It's out of their control. What they can do is control their salesforce to make sure that the messaging is all as per label. And we think it's worth noting that Nova have yet to actually do any sort of direct to consumer advertising in the US.

Anyone who brings up TikTok Instagram and puts Wegovi in sees what's going on here. I don't think Novo would condone what's going on in terms of off label promotion. I think there's a fine line between prescribing off label and prescribing totally against the advice of the manufacturer and of all the other organizations that create guidelines. I don't think there'll be a huge issue in terms of people taking it outside of the recommended BMI ranges, at least not legitimately. CNBC's Meg Turrell asked Nova, Nordisk's CEO about the off label use of its drugs. We're always concerned about safety of our medicines, and that's why we really focus on promoting it the right way, getting to physicians and describing how our products should be used.

There's also one big known catch. If a patient stops taking the drugs, they're likely to regain most of the weight lost. This means a patient might end up injecting for life if they want to keep the weight off. How do you feel about the fact that, you know, there's a possibility that if you stop taking the treatment, that you might put some of the weight or all of the weight back on? Yeah, that scares me. And somewhere where I've been as well, I've sat and here lighter. But I think this drug is so new that perhaps, maybe down the line, it might be something where they say it's something you need to take long term.

Wiggavi can cost over $1,000 a month in the US out of pocket. So affordability is a big barrier for these drugs. Analysts do expect these costs to come down over time as more versions enter the market. If insurers and public health institutions can be convinced that the drugs reduce the risk of long term weight related complications like cardiovascular disease, they might be inclined to help foot the bill. There is a very strong or very important study looking at Wegovi in 17,000 non diabetics but obese patients. Its primary aim is to look at the cardiovascular benefit of we go be so, does it reduce the number of strokes and heart attacks?

Now that trial is positive. I think that would add fuel to the fire. It also opens the door is what's going to happen in Medicare? Beyond safety and cost, there is concern that if drugs like these are used by individuals with more modest weight loss goals, it could take the body positivity movement in the wrong direction. The finance community is exuberant about the potential of these drugs. Novo Nordisk's share price has doubled over the last two years, and still healthcare analysts think it could go higher from here.

There's no reason why the GLP one market in diabetes alone could be worth 40 billion plus over time. Then we moved to GLP one and obesity. Novo is the only show in town today. They generated over $2 billion of sales in 2022. Ultimately, this isn't just about one company. While Novo Nordisk has been the leader, Eli Lilly, Pfizer and Moore are all hoping to get a piece of the pie.

With a whole host of promising obesity drugs in the pipeline around the world. Doesn't matter whether it's North America, Europe, Asia, you're seeing phenomenal growth. The current script trends are ridiculous. I absolutely think this is a unique drug class. And that Lilian Novo will probably have two of the biggest selling drugs that we've ever seen across. Diabetes, obesity. I've never seen anything like this in my 20 years, no.
