— Experienced R&D leader with a track record of advancing innovative therapies from early development to global approval — RESEARCH TRIANGLE PARK, N.C., April 06, 2026 (GLOBE NEWSWIRE) -- BioCryst Pharmaceuticals, Inc. (Nasdaq: BCRX) today announced the appointment of Sandeep M. Menon, MD, PhD, as Chief Research and Development Officer. Building on the commercial success of ORLADEYO ® and the recent acquisition of Astria Therapeutics and the navenibart program, BioCryst is entering a new phase of execution in its strategy to build value through development and commercialization of rare disease therapies. Dr. Menon joins BioCryst from Alnylam Pharmaceuticals, where he served as Chief Development Officer, overseeing global clinical development and safety across a broad portfolio spanning multiple therapeutic areas. Under his leadership, his team read out and secured FDA approval of AMVUTTRA ® (vutrisiran), a novel RNAi therapeutic for ATTR cardiomyopathy, and advanced multiple programs through key clinical milestones. “As BioCryst enters a critical phase, our priority is disciplined drug development and flawless regulatory delivery for innovative therapies that can change patients’ lives. Sandeep brings a proven record of leading complex programs through approval, scaling global R&D organizations, and making tough, value-driven decisions,” said Charlie Gayer, President and Chief Executive Officer of BioCryst. “With navenibart advancing toward a potential BLA and a growing pipeline behind it, his leadership strengthens our ability to sharpen our R&D strategy, balance capital allocation and risk, and create durable long-term value through repeated rare disease launches.” Previously, Dr. Menon spent over a decade at Pfizer in senior R&D leadership roles, most recently as Senior Vice President, Head of Early Clinical Development and Chief Scientific Officer, BioMedicine AI and Digital Sciences. He led large, global development organizations and played a key role in improving R&D success rates across the portfolio. He co-led the clinical development of PAXLOVID™, which progressed from first-in-human dosing to emergency use authorization in nine months, and contributed to the development and approval of multiple therapies across oncology, immunology and rare disease. Earlier in his career, Dr. Menon held clinical development and biostatistics leadership roles at Biogen Idec and Aptiv Solutions (ICON). “BioCryst is at a critical inflection point in its history and I am excited to join as the company enters its next stage of growth,” said Dr. Sandeep Menon, Chief Research and Development Officer of BioCryst. “BioCryst has built a growing rare disease business with strong commercial momentum, a differentiated portfolio, and a clear path to expand it. I look forward to working alongside the team to advance our development programs and deliver medicines that can transform patients’ lives.” Dr. Menon holds a PhD in Biostatistics and an MPH in Epidemiology and Biostatistics from Boston University, an MS in Translational Pharmacology from The Ohio State University, and a medical degree from Karnataka University in India.
