Key Takeaways:

Rosen Law Firm said Monday it is investigating potential securities claims against Disc Medicine Inc. after the company’s stock plunged 22% in a single day on negative regulatory news.
"The Rosen Law Firm is preparing a class action seeking recovery of investor losses," the firm stated in a press release issued May 25.
The investigation centers on allegations that Disc Medicine may have issued misleading business information. On Feb. 13, 2026, the U.S. Food and Drug Administration (FDA) issued a Complete Response Letter (CRL) for the company's bitopertin new drug application, citing uncertainties that required more evidence. Disc Medicine's shares fell 22% on the day of the announcement.
The law firm's action seeks to compensate shareholders who purchased securities and suffered losses. Investors who purchased stock may be entitled to compensation without out-of-pocket fees through a contingency arrangement.
The investigation introduces significant legal and financial risk for Disc Medicine, potentially leading to a costly class-action lawsuit. Investors will be watching for the company's formal response to the allegations and any further updates from the FDA on the bitopertin program.
