BOSTON, May 11, 2023 (GLOBE NEWSWIRE) -- 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 reported financial results for the first quarter ended March 31, 2023.

“PepGen has had an impressive start to 2023 and anticipates a meaningful year ahead. This progress builds upon the positive results we reported in Q4 2022 from our Phase 1 Healthy Volunteer (HV) clinical trial of PGN-EDO51, which exhibited the highest levels of oligonucleotide delivery and exon skipping in a clinical study following a single dose,” said James McArthur, Ph.D., President and CEO of PepGen. “Looking ahead, we anticipate initiating CONNECT1-EDO51, a Phase 2 study in Canada in the first half of 2023, which we expect will allow us to report dystrophin production, exon skipping and safety data following 4 monthly doses of PGN-EDO51 in 2024.”

Dr. McArthur continued, “We also remain focused on the balance of our Enhanced Delivery Oligonucleotide (EDO) portfolio of candidate therapeutics. Based on the encouraging non-clinical data from PGN-EDODM1, we anticipate initiating the Phase 1 FREEDOM-DM1 study in myotonic dystrophy type 1 (DM1) patients in the first half of 2023. We look forward to continuing to advance our potentially transformative therapeutics to address areas of great unmet need.”

Recent Corporate Highlights

• In March 2023, PepGen gave two oral presentations and presented a poster updating the community on the PGN-EDO51 and PGN-EDODM1 programs and shared previously reported positive PGN-EDO51 Phase 1 clinical data at the 2023 Muscular Dystrophy Association Clinical & Scientific Conference.
• In April 2023, PepGen gave an oral and poster presentation on the preclinical data supporting the development and advancement of PGN-EDODM1 into clinical studies, the design of the proposed Phase 1 clinical trial, FREEDOM-DM1, and preclinical and Phase 1 PGN-EDO51 data at the American Academy of Neurology 2023 Annual Meeting.

Anticipated Upcoming Milestones

• PGN-EDO51: PepGen anticipates initiating CONNECT1-EDO51; an open-label, multiple ascending dose (MAD) Phase 2 study in Canada in the first half of 2023 and CONNECT2-EDO51; a Phase 2 multinational, randomized, double-blind, placebo-controlled MAD study (RCT) in the second half of 2023 in boys and young men living with DMD. Learnings from the open-label study will inform the global RCT, which is designed to support a potential accelerated or conditional approval pathway pending alignment with regulatory authorities.
• PGN-EDODM1: PepGen anticipates initiating, FREEDOM-DM1, a randomized, double-blind, placebo-controlled, single ascending dose (SAD) Phase 1 Study in people living with DM1 in the first half of 2023.
