PepGen Shares Fall After FDA Puts Myotonic Dystrophy Trial on Hold

Dow Jones

03/05

By Nicholas G. Miller

Shares of PepGen slid after the Food and Drug Administration put a partial clinical hold on a study of its treatment for Myotonic Dystrophy, a genetic disorder that causes progressive muscle loss and weakness.

The stock fell 19% to $5.50 in Thursday's off-hours trading. It has more than doubled over the past 52 weeks.

The company said the FDA raised questions related to previously- submitted preclinical pharmacology and toxicology studies.

PepGen said it "is committed to working with the FDA to address the Agency's questions as quickly as possible."
