Pending FDA clearance, the company plans a Phase 1/2a study evaluating safety, dosing and early efficacy in advanced pancreatic cancer patients resistant to conventional immunotherapy.Fractyl Health received European approval to begin a first-in-human Phase 1/2 trial of RJVA-001, GLP-1 gene therapy for obesity and type 2 diabetes. The therapy uses endoscopic ultrasound-guided pancreatic delivery to program beta cells to produce GLP-1 in response to meals rather than relying on repeated injections.Ossium Health presented clinical trial data showing successful engraftment using cryopreserved bone marrow collected from deceased organ donors. Researchers believe the banking platform could eventually simplify bone marrow transplantation logistics and expand future immune system renewal applications.Cyclarity shared new progress on therapies targeting 7-ketocholesterol, an oxidized cholesterol molecule linked to plaque instability and chronic arterial inflammation. Rather than slowing plaque growth, the company aims to physically remove toxic cholesterol deposits already embedded within blood vessel walls.Microbiotica reported positive Phase 1b MELODY-1 trial data for MB097, a microbiome therapy containing nine bacterial strains combined with KEYTRUDA in advanced melanoma patients. The therapy showed successful gut engraftment and encouraging signals that microbiome modulation may help overcome immunotherapy resistance.The episode also explored health equity in longevity medicine with Poonam Desai ahead of The Longevity Show. Discussions focused on sex-specific medicine, unequal access to longevity care and the risks of building precision health systems around biased clinical data.----------News & References:‘Rebuilding the human immune system is possible’ → https://longevity.technology/news/rebuilding-the-human-immune-system-is-possible/Fractyl Health to begin EU trials for one-time weight loss gene therapy → https://longevity.technology/news/fractyl-health-to-begin-eu-trials-for-one-time-weight-loss-gene-therapy/Matter Bio takes pancreatic therapy to clinic → https://longevity.technology/news/matter-bio-takes-pancreatic-therapy-to-clinic/New data suggests plaque damage can be cleared → https://longevity.technology/news/new-data-suggests-plaque-damage-can-be-cleared/Microbiome medicine moves past wellness into clinics → https://longevity.technology/news/microbiome-medicine-moves-past-wellness-into-clinics/‘Equity in longevity is the entire ballgame’ → https://longevity.technology/news/equity-in-longevity-is-the-entire-ballgame/
