0:00 the fda just gave accelerated approval to a new breast cancer drug that extends the time before cancer progresses from nine months to sixteen this is more than just another drug approval it's a sign that medicine is shifting from a blunt instrument to a precision tool last week we discussed the rapid pace of change in cancer and obesity0:22 treatments this week we're seeing exactly how that new precision is being deployed the big theme this week is targeting instead of treating a disease based on where it is in the body we're treating it based on what it's doing at a molecular level nowhere is this clearer than in breast cancer september saw the approval of camazestrant the0:44 fourth new oral drug in a class called serds think of these as smart bombs that block estrogen from fueling certain types of breast cancer what's different about this latest approval is how it's used the serena six trial didn't just give the drug to everyone doctors used a simple blood test a liquid biopsy to watch for a specific1:04 mutation called esr1 which helps the cancer resist standard treatment once that mutation appeared they switched the patient to camisestrant the result a median of sixteen months of progression free survival compared to just over nine months for those who stayed on the old therapy this is one of 10 new cancer treatments approved in september alone for everything from1:29 lung and kidney cancer to brain tumors the pattern is clear find the cancer's specific vulnerability then hit it with a drug designed for that exact target and a quick reminder this is general information from the latest research not medical advice for your specific situation always discuss treatment options with your physician this idea of targeting the root cause1:54 is also showing up in longevity research at a conference at harvard just last week the fda gave what one observer called a candid map of the terrain for approving anti aging therapies for the first time the agency is actively exploring how to regulate treatments that target aging itself as a treatable condition this is a foundational shift it's2:16 the difference between patching leaks in an old house and reinforcing the foundation the pathway isn't built yet but the surveyors are officially on the job and we're seeing early hints of what those therapies might look like a new study in mice looked at semaglutide a glp-one agonist used in popular obesity drugs when given to mice late in2:38 life it increased their median lifespan by over twelve percent crucially the data suggests this effect went beyond what you'd expect from just caloric restriction it points to a deeper mechanism that improves health and extends life again this is in mice but it's a powerful signal that drugs developed for one condition might have profound effects on the aging3:05 process itself so let's go back to that cancer therapy because it's the clearest picture of the future the old way was to give a treatment until it failed you'd wait for a scan to show the tumor was growing again and only then would you change course by then you've lost ground the strategy in the serena six trial3:27 is completely different it's a strategy of active surveillance you use a liquid biopsy to monitor the cancer's dna in the bloodstream in near real time you're not waiting for the cancer to grow you're watching for it to evolve the moment it develops a new weapon that esr1 mutation you switch to a drug that neutralizes that specific weapon3:51 it's proactive not reactive and the payoff is an extra seven months before the disease progresses that is a massive gain one not just by a new molecule but by a smarter strategy so what is this all set up the convergence of these fields the tools being perfected in cancer care liquid biopsies biomarker tracking targeted therapies are the4:17 same tools that will define the future of longevity medicine the distinction between treating disease and promoting wellness is going to blur your health management will become less about annual checkups and more about continuous data driven adjustments the goal is no longer just to fight sickness when it appears the goal is to use precise targeted interventions to maintain4:42 health at a high level for as long as possible
