Mereo BioPharma faces securities class action over setrusumab bone mineral density claims

A securities class action is pending against Mereo, with an alleged class period from June 5, 2023 through December 26, 2025. The complaint alleges the company made repeated statements that setrusumab-driven bone mineral density gains would translate into reduced fracture rates in osteogenesis imperfecta patients. It also alleges Mereo cited Phase 2 results including a 67% reduction in annualized fracture rate, while omitting that the data lacked control-group comparisons needed to establish causation. The suit further alleges management knew the Phase 2 results could not distinguish setrusumab’s effects from changes due to standard of care or placebo effects. A court deadline to apply for lead plaintiff appointment has been set for April 6, 2026.
