-Company continues to advance PGN-EDO51 in CONNECT1-EDO51, with the 10 mg/kg cohort now fully enrolled-

BOSTON, December 16, 2024--(BUSINESS WIRE)--PepGen Inc. (Nasdaq: PEPG), 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 that the Company received a clinical hold notice from the U.S. Food and Drug Administration (FDA) regarding its Investigational New Drug (IND) application to initiate the CONNECT2-EDO51 clinical trial in patients with Duchenne muscular dystrophy (DMD). The FDA indicated they will provide an official clinical hold letter to the Company within 30 days.

CONNECT2 is PepGen’s Phase 2 multinational, double-blind placebo-controlled, multiple ascending dose, 25-week clinical trial of PGN-EDO51 in patients with DMD. The study is open in the United Kingdom.

"We intend to work closely with the FDA to address their questions on our application to initiate CONNECT2 as expeditiously as possible," said Paul Streck, MD, MBA, Head of R&D of PepGen. "Our open-label CONNECT1-EDO51 multiple ascending dose study of PGN-EDO51 in boys and young men living with DMD continues as planned in Canada. We have completed enrollment of the 10 mg/kg dose cohort; all four patients in this cohort have received at least one dose."

About PGN-EDO51

PGN-EDO51, PepGen's clinical candidate for the treatment of DMD, utilizes the Company's proprietary Enhanced Delivery Oligonucleotide (EDO) technology to deliver a therapeutic phosphorodiamidate morpholino oligomer (PMO) that is designed to target the root cause of this devastating disease. PGN-EDO51 is designed to skip exon 51 of the dystrophin transcript, an established therapeutic target for approximately 13% of DMD patients, thereby aiming to restore the open reading frame and enabling the production of a truncated, yet functional dystrophin protein. The FDA has granted PGN-EDO51 both Orphan Drug and Rare Pediatric Disease Designations for the treatment of patients with DMD amenable to an exon-51 skipping approach.
