PaxMedica Appoints Stefan Schwabe MD, PhD as Chief Medical Officer

Dr. Schwabe brings 30+ years of Clinical Experience in the Pharmaceutical Industry 


TARRYTOWN, NY - (NewMediaWire) - October 24, 2022 - PaxMedica, Inc. (Nasdaq: PXMD), a clinical-stage biopharmaceutical company focused on the development of anti-purinergic drug therapies (“APT”) for the treatment of disorders with intractable neurologic symptoms such as autism spectrum disorder (“ASD”), today announced the appointment of Dr. Stefan Schwabe MD, PhD as Chief Medical Officer.  In this role, Dr. Schwabe will be responsible for overseeing and directing product development activities including pre-clinical, clinical, regulatory and pharmaceutical sciences for PaxMedica’s pipeline products. The initial program underway is targeting antipurinergic drug therapies.  

Howard Weisman, CEO of PaxMedica, commented, “We welcome Stefan to PaxMedica, and look forward to his contributions as Chief Medical Officer.  PaxMedica is entering an important phase as we work to advance our clinical programs and Stefan’s experience and expertise in neurology and drug development will help us build the critical evidence needed to ultimately seek regulatory approval for PAX-101.”

Dr. Schwabe added, “I’m excited to be joining a company committed to developing solutions to disorders with high unmet medical needs through an innovative approach using clinical data to repurpose a well-known compound that has been used for many years to treat a rare fatal infection. The initial clinical data for its possible use in ASD is exciting, supported by a working hypothesis of a putative mechanism of action based on purine-mediated processes.  If successful, this could bring hope to the many individuals and their families that struggle with this spectrum of disorders without any definitive medical treatments. I look forward to working with the enthusiastic and experienced team at PaxMedica.” 

Dr. Schwabe has over 30 years of experience in the pharmaceutical industry. Dr. Schwabe worked in the CNS area at Ciba-Geigy, Novo Nordisk, J&J, Novartis and Sanofi in various capacities in clinical development, medical affairs and project management. Most recently, Dr. Schwabe served as Executive Vice President of Research and Development and Chief Medical Officer of Supernus Pharmaceuticals since 2012. Previously, he was the Chief Operating Officer at DemeRx, a privately held biotech company working in the area of addiction. Dr. Schwabe received a PhD in clinical toxicology from the University of Munich, an MD degree from Ludwig-Maximilians-Universität München, Germany, and a Bachelor of Science in Chemistry from Florida International University and he completed a residency in Neurology from the Medical College of Wisconsin.

About PaxMedica

PaxMedica is a clinical stage biopharmaceutical company focusing on the development of anti-purinergic drug therapies (“APT”) for the treatment of disorders with intractable neurologic symptoms, ranging from neurodevelopmental disorders, including Autism Spectrum Disorder (“ASD”), to Myalgic Encephalomyelitis/Chronic Fatigue Syndrome (“ME/CFS”), a debilitating physical and cognitive disorder believed to be viral in origin and now with rising incidence globally due to the long term effects of SARS-CoV-2 (“COVID-19”). One of PaxMedica’s primary points of focus is the development and testing of its lead compound, PAX-101, an intravenous formulation of suramin, in the treatment of ASD and the advancement of the clinical understanding of using that agent against other disorders such as ME/CFS and Long COVID-19 Syndrome, a clinical diagnosis in individuals who have been previously infected with COVID-19.
