BOSTON, September 22, 2022 – PepGen Inc. (“PepGen”), a clinical-stage biotechnology company advancing the next generation of oligonucleotide therapies with the goal of transforming the treatment of severe neuromuscular and neurological diseases, today announced the appointment of Habib Joseph Dable to its Board of Directors. Mr. Dable is the former President and Chief Executive Officer of Acceleron Pharma, and brings nearly three decades of experience working with emerging biotech and big pharma companies.


“Habib joins the Board at a pivotal time for PepGen, as we continue to execute our clinical development strategy for PGN-EDO51, our lead candidate in Duchenne muscular dystrophy, and continue to advance our research efforts in myotonic dystrophy type 1,” said James McArthur, Ph.D., President and Chief Executive Officer of PepGen. “His deep experience as an executive and Board member in this industry, and his extensive understanding of the neurology landscape, will add tremendous value to our Board as we advance our programs and continue our corporate development efforts.”


As President and Chief Executive Officer of Acceleron Pharma, Mr. Dable guided Acceleron to a new stage of growth and shareholder value, leading to Acceleron’s first blockbuster launch in 2019 and eventual sale to Merck & Co. in 2021 for over $11 billion. Prior to his role at Acceleron, Mr. Dable worked at Bayer AG where, over the course of his 22-year tenure, he served in roles of increasing responsibility, including Global Head, Neurology and Ophthalmology and President of U.S. Pharmaceuticals. During this time, Mr. Dable led the launch of various blockbuster brands, including EYLEA®, Stivarga®, and Xofigo®. Mr. Dable is also a former Independent Director of Millendo Therapeutics and previously served on the Board of Directors of the Biotechnology Innovation Organization (BIO). He currently serves as an Independent Director at Blueprint Medicines and Albireo Pharma, and is a part-time Venture Partner at RA Capital Management. Mr. Dable received a bachelor’s degree in Business Administration and an MBA from the University of New Brunswick.


Mr. Dable commented, “Leveraging its proprietary Enhanced Delivery Oligonucleotide technology, PepGen has the potential to develop best-in-class therapies for neuromuscular and neurologic diseases such as Duchenne muscular dystrophy. I am delighted to join the Board of Directors and look forward to working with James and the Board to advance PepGen as a leading company developing potentially transformative therapies for people living with these devastating diseases.”


PepGen’s Board Chair, Laurie Keating remarked, “Habib’s broad experience and exemplary successes as CEO of Acceleron and in a variety of key roles at Bayer AG, as well as his specific experience with the development of potential new treatments for genetic muscle disorders, will be invaluable as PepGen continues to advance its innovative pipeline and build a distinctive, innovation-based company. We are thrilled to welcome Habib to our Board and look forward to his contributions to our efforts to bring new disease modifying medicines to patients and families in great need.”
