PepGen Shares Plunge 44% After Mixed Mid-Stage Trial Results
- Disappointing Trial Results: PepGen (PEPG) shares plummeted approximately 44% in after-hours trading following the mid-stage trial results for its lead treatment PGN-EDODM1, which showed no significant improvements in handgrip strength or 10-meter walk/run tests at the 5 mg/kg dose cohort.
- Ongoing Research Plans: Despite the disappointing results, the company plans to continue studying the 10 mg/kg dose cohort, with data expected in H2 2026, indicating the company's ongoing confidence in the drug's potential.
- Divergent Analyst Opinions: While Leerink Partners analyst Joseph Schwartz highlighted the mixed nature of the data, Oppenheimer's Kostas Biliouris argued that the selloff was overdone, maintaining that PGN-EDODM1 still shows positive drug effects and may yield better results at higher doses.
- Market Reaction Analysis: Despite some analysts' optimism regarding the drug, PepGen's stock remains under pressure due to a partial FDA hold on the mid-stage trial, reflecting market sensitivity to clinical data and concerns about the company's future prospects.
