Impossible Dreams
What if the key to reversing ALS isn't replacing dead neurons, but reawakening the connections between the ones that are still alive? In this groundbreaking episode, host Aaron Lazar sits down with Dr. Stella Sarraf, serial biotech entrepreneur, Forbes 50 Over 50 honoree for Innovation, and founder and CEO of both Spinogenix and Amydis. A PhD chemist turned drug developer, Dr. Sarraf is pioneering first-in-class neuroregenerative therapeutics that work at the synaptic level to restore brain function in ALS, Alzheimer's, schizophrenia, and Fragile X syndrome. Her investigational drug SPG302 has received FDA expanded access authorization to treat 200 ALS patients, and Orphan Drug Designation from the European Medicines Agency. This conversation is both a masterclass in drug development and a deeply personal story of loss and purpose. Dr. Sarraf opens up about losing her father to Parkinson's and her mother to breast cancer, and how those experiences ignited her mission to transform neurology from a field of late diagnosis and limited options into one of early detection and real treatment. She describes the decade-long marathon from lab bench to clinical trial, the mouse that started running circles after treatment, and the impossible dream of turning ALS from a death sentence into a chronic, manageable disease. The impossible dream shines brightest in Dr. Sarraf's patient-first approach to expanded access. Rather than wait years for traditional clinical trial pathways, she fought for FDA authorization to offer SPG302 to ALS patients who wouldn't otherwise qualify, passing costs to patients rather than profits to shareholders. It's the same spirit that drove her to found Amydis: using the eye as a window to the brain to detect neurodegenerative disease proteins like TDP-43 before symptoms appear, potentially catching ALS at the earliest possible stage. Guest Bio: Dr. Stella Sarraf is a visionary biotech entrepreneur and the founder and CEO of Spinogenix and Amydis. Named to Forbes 50 Over 50: Innovation (2025), she holds a PhD in organic chemistry from Columbia University and a BA in biochemistry and molecular biology from UC Berkeley. Dr. Sarraf began her career as a senior research chemist at Merck Research Laboratories, where she developed novel drug synthesis processes for clinical trials. She then spent over a decade in healthcare venture capital at Foresite Capital Management and Prospect Venture Partners, leading diligence on 400+ investment opportunities in therapeutics and diagnostics. In 2013, she founded Amydis to develop ocular tracers for early detection of neurodegenerative disease biomarkers including TDP-43 (present in 97% of ALS patients) and amyloid beta. In 2016, she founded Spinogenix to develop synaptic regenerative therapies. The company's lead drug SPG302 is in clinical trials for ALS, Alzheimer's, and schizophrenia, with FDA expanded access authorization to treat 200 ALS patients. Hall of Fame quarterback Steve Young serves on the Spinogenix board. Dr. Sarraf was born in Iran and is driven by her personal experience losing both parents to neurodegenerative disease.
