(Nasdaq: ALT), a late clinical-stage biopharmaceutical company developing novel peptide-based therapeutics for liver and cardiometabolic diseases, today announced the appointment of Linda M. Richardson to the role of Chief Commercial Officer, effective September 16, 2025. Ms. Richardson joins the Company with more than 30 years of experience in sales and marketing, commercial, corporate and business development across a range of therapeutic areas, including metabolic disease, hepatology, cardiovascular and addiction medicine. During her career, she has led multiple product launches, built successful commercial franchises and contributed to a variety of business development transactions. “Linda joining Altimmune marks a key strategic addition to our executive team as we approach the initiation of Phase 3 development of pemvidutide in MASH. To add a leader with her pedigree positions Altimmune, and pemvidutide, for future commercial success,” said Vipin K. Garg, Ph.D., President and CEO of Altimmune. “Her deep expertise and strong track record will be instrumental to our strategic business execution and growth.” Ms. Richardson added, “I believe that pemvidutide represents a rare opportunity in the area of hepato-metabolic disease and is differentiated from other marketed and development-stage therapies with significant potential to improve the lives of patients with MASH. Additionally, there are sizeable opportunities in Alcohol Use Disorder and Alcohol-associated Liver Disease where we continue to investigate the potential utility of pemvidutide in these highly prevalent and underserved indications. I am pleased to bring my experience to Altimmune and thrilled to begin leading Altimmune’s commercial-readiness efforts.” Ms. Richardson served as Chief Commercial Officer and Executive Vice President at Intercept Pharmaceuticals, a liver disease company, departing in early 2024 following the Company’s acquisition by Alfasigma. Prior to joining Intercept, she was Chief Strategy and Commercial Officer at Chimerix. Earlier in her career, she held a variety of senior-level marketing and commercial positions, including at Sanofi, where she was Global Commercial Head of Lixisenatide, the Company’s GLP-1 program and Marketing Lead for MULTAQ and AUVI-Q, Reliant Pharmaceuticals, where she launched Lovaza for hypertriglyceridemia, and at GSK. She holds a bachelor’s degree in English from the University of Pennsylvania.
