A securities fraud class action lawsuit has been filed against Mereo BioPharma Group plc on behalf of investors who bought the company’s American Depositary Shares between June 5, 2023 and December 26, 2025. The complaint alleges the company misrepresented results from the ORBIT and COSMIC Phase 3 trials of setrusumab for Osteogenesis Imperfecta; Mereo later disclosed that neither study met its primary endpoint, after which the ADS price fell more than 87% in one trading day. Investors have until April 6, 2026 to seek appointment as lead plaintiff.
