Gainey McKenna & Egleston Announces A Class Action Lawsuit Has Been Filed Against PepGen Inc. (PEPG)

NEW YORK, June 10, 2025 (GLOBE NEWSWIRE) — Gainey McKenna & Egleston announces that a securities class action lawsuit has been filed in the United States District Court for the Eastern District of New York on behalf of all persons or entities who purchased or otherwise acquired PepGen Inc. (“PepGen” or the “Company”) (NASDAQ: PEPG) securities between March 7, 2024 and March 3, 2025, both dates inclusive (the “Class Period”).

The Complaint alleges that Defendants made false and/or misleading statements and/or failed to disclose that: (i) PGN-EDO51 was less effective and safe than Defendants had led investors to believe; (ii) the CONNECT2 study was dangerous or otherwise deficient for purposes of U.S. Food and Drug Administration (“FDA”) approval; (iii) as a result of all the foregoing, PepGen was likely to halt the CONNECT2 study, and PGN-EDO51’s clinical, regulatory, and commercial prospects were overstated; and (iv) as a result, Defendants’ public statements were materially false and misleading at all relevant times.

On July 30, 2024, PepGen issued a press release announcing purported “positive clinical data from the first dose cohort (5 mg/kg) of PGN-EDO51” in its ongoing CONNECT1 study. Among other results, the Company reported that “PGN-EDO51 achieved a mean absolute dystrophin level of 0.61% of normal and a 0.26% change from baseline after 4 doses, measured at week 13 by Western blot analysis.” However, as subsequently noted by a Stifel analyst, “the magnitude of dystrophin increase was below what [PepGen] anticipated, which is disappointing[.]” Likewise, a Leerink Partners analyst noted that the low dose missed PepGen’s expectations of 1% or greater dystrophin expression.

On this news, PepGen’s stock price fell $5.55 per share, or 32.69%, to close at $11.43 per share on July 31, 2024.
