Event Summary

Faruqi & Faruqi, a national securities law firm, is investigating potential claims against Mereo BioPharma Group plc and is reminding investors of the April 6, 2026 deadline to seek the role of lead plaintiff in a federal securities class action. The lawsuit stems from Mereo BioPharma Group's announcement on December 29, 2025, that two Phase 3 studies of setrusumab failed to meet their primary endpoints of reducing annualized clinical fracture rates. This news led to an 87.64% drop in Mereo BioPharma Group's stock price, closing at $0.28 per share. The complaint alleges that Mereo BioPharma Group and its executives made false and/or misleading statements and/or failed to disclose the true state of the Phase 3 ORBIT and COSMIC programs.
