Vor Bio Appoints Jeremy Sokolove, M.D. as Chief Medical Officer

BOSTON, Mass., November 3, 2025 (GLOBE NEWSWIRE) — Vor Bio (Nasdaq: VOR), a clinical-stage biotechnology company transforming the treatment of autoimmune diseases, today announced the appointment of Jeremy Sokolove, M.D., as Chief Medical Officer. Dr. Sokolove brings more than two decades of clinical and translational experience in rheumatology and autoimmune disease research and development to the company’s leadership team.

“We are thrilled to welcome Jeremy to Vor Bio,” said Jean-Paul Kress, M.D., Chief Executive Officer and Chairman of the Board. “His deep clinical expertise as a rheumatologist, coupled with his strong track record in industry and as a thought leader in autoimmune and inflammatory disease clinical research, makes him a perfect fit to drive our clinical strategy. With Jeremy on board, we are more confident than ever in advancing our dual BAFF/APRIL approach toward meaningful impact for patients.”

Most recently, Dr. Sokolove served as Chief Medical Officer In-Residence at Roivant Sciences where he led strategic assessment and in-licensing of novel therapeutic opportunities while providing operational leadership, clinical guidance, and translational expertise across Roivant’s emerging and established portfolio companies. Before that, he was Chief Medical Officer at Odyssey Therapeutics, leading the transition of the company to a clinical-stage biotechnology organization focused on next-generation immunomodulators for autoimmune and inflammatory diseases. Earlier, Dr. Sokolove was Senior Vice President and Head of Clinical Pharmacology and Experimental Medicine at GSK, where he led early and translational development across the specialty pharma portfolio, and previously Head of Immunology Translational Science at AbbVie, directing early-phase clinical programs and building portfolio-wide translational medicine strategy. He began his career on the faculty at Stanford University School of Medicine as a practicing rheumatologist and primary investigator, where his research focused on biomarker discovery and immune-mediated disease mechanisms.

Dr. Sokolove has practiced extensively as an internist and rheumatologist, treating patients and leading clinical research programs focused on autoimmune and inflammatory disorders. He has published extensively in the fields of immunology and rheumatology, contributing to the understanding of immune-mediated disease mechanisms. His academic credentials include board certification in internal medicine and rheumatology, and he holds an MD from the Boston University School of Medicine.

“I am joining Vor Bio because I see strong scientific and clinical potential in the BAFF/APRIL pathways to precisely modulate the core mechanisms underlying autoimmune diseases,” said Dr. Sokolove. “Telitacicept represents a differentiated, near-term opportunity to meaningfully improve outcomes for patients with limited therapeutic options or those who depend on broad immunosuppression. I look forward to working with the team to execute a global clinical development program for Telitacicept that could translate into a therapy that can make a real difference in the lives of patients.”
