Welcome back to the BowTiedBiotech Podcast, your weekly rundown of the biggest stories shaping the biotech markets. This week, we’re diving into a flurry of major moves across immunology, inflammation, and aging. Kymera landed two headline-grabbing deals, with Gilead betting up to $2 billion on its protein degradation platform, while Sanofi backed off its lead program but stayed in the game. We’ll break down what this means for STAT6 and the future of targeted protein degradation. Then we unpack Nektar’s rezpeg trial win in eczema and why analysts still aren’t sold. From the collapse of TIGIT, to Amgen’s monthly obesity contender, and a $570M Calico aging deal, to a SPAC-fueled debut for mitochondrial medicine, this week was biotech in full tilt. Let’s get into it.
