Karl Pfleger Explains the Aging Biotech Explosion
On this episode of Longevity by Design, Dr. Gil Blander sits down with Dr. Karl Pfleger, aging biotechnology investor and creator of AgingBiotech.info, to dissect the rapidly evolving field of aging therapeutics. Karl breaks down the sector into two main categories: interventions that slow aging rates versus rejuvenation strategies that repair accumulated damage.
Karl highlights the most promising areas in his investment portfolio, including senolytics for clearing senescent cells and epigenetic reprogramming technologies. He explains why current aging clocks aren't ready for clinical use and discusses the limitations of popular interventions like GLP-1 drugs and fasting protocols. The conversation reveals that 14 Phase 3 clinical trials are currently testing core aging therapeutics.
The discussion covers recent FDA approvals for ATTR treatments and stem cell therapies, signaling the field's maturation. Karl emphasizes that meaningful life extension requires a "divide and conquer" strategy, targeting multiple aging mechanisms simultaneously rather than relying on single interventions. Despite exciting therapeutic developments, he maintains that optimizing diet, exercise, and sleep remains the most impactful strategy for extending healthspan today.
