0:00 novo nordisk just announced their new drug combination cagrisma showed superior weight loss compared to tirzotide in a head to head trial last week we talked about the current landscape of obesity therapies this week that landscape just shifted here's what else is moving first a major commission in the lancet oncology just highlighted profound global inequities in access to0:27 cancer genomics the data and trials are concentrated in high income countries and among people of european ancestry leaving millions without access to precision oncology that could save their lives it's a systemic problem that science alone can't fix second for anyone on a glp-one drug like ozempic or wegovy a new analysis just confirmed a modest increase in the0:52 risk of acute pancreatitis the data from the faers database shows the risk is concentrated in the first six months of treatment the hazard ratio is one point zero six so it's a small but real signal that supports paying close attention to any new pancreatic symptoms when you start these drugs it doesn't change the overall benefit but it1:13 refines our understanding of the risk and finally a new clinical trial just started that points to the future of obesity treatment wave life sciences is testing a new drug wve-seven in combination with tirzepatide the goal isn't just to cause more weight loss but to specifically enhance fat loss while preserving muscle this is a critical next step addressing1:37 one of the biggest concerns with rapid weight loss so let's go deeper into this obesity drug arms race for the past couple of years the story has been about the battle between semaglutide that's novo nordisk's drug in ozempic and wegovy and tirzepatide which is eli lilly's mounjaro and zepbound tirzepatide looked like the winner since it acts on1:56 two receptors gip and glp-one and generally produced more weight loss now novo nordisk has fired back their new top line data on cagrisma is a direct challenge cagrsima is a combination of two drugs in one weekly shot semaglutide the glp-one agonist you already know plus a new compound called cagrelentide cagrelentide mimics a different hormone called amylin so2:21 what does amylin do it works with glp-one to control blood sugar slow stomach emptying and reduce appetite it's a different pathway to the same goal by combining them you get a stronger effect and the results show it in a phase three trial for adults with type two diabetes kagrisima produced 12.4% weight loss tirzepatide in the same trial2:42 produced 9.1% that is a statistically significant win for kagrisima in another trial on people with obesity but not diabetes it delivered twenty one percent weight loss versus a placebo so what does this all add up to you are watching the evolution of obesity medicine in real time we are moving past single hormone mimics to multi hormone combination3:06 therapies first it was glp-one alone then glp-one plus gip now it's glp-one plus amylin each step brings more efficacy but it also brings more complexity remember that pancreatitis signal it's a reminder that these are powerful drugs with real side effects and the research is also starting to unpack why they don't work for everyone a new report in3:33 nature highlights that biological sex genetics and behavior all play a role for example women tend to lose more weight than men on these drugs possibly because estrogen enhances the drug's effects this isn't a one size fits all solution not yet this is exactly why that wave life sciences trial is so important they are targeting a gene called3:55 inhbe to specifically block the storage of visceral fat and preserve muscle mass during weight loss that's the next frontier it's not just about the number on the scale it's about changing body composition in a healthy way this week's developments confirm that the pace of innovation in metabolic medicine is not slowing down it's accelerating the question is no4:22 longer if we can treat obesity effectively with medication the question is becoming how precisely we can tailor that treatment to maximize fat loss preserve healthy tissue and minimize risk for each individual that's the work that starts now
