During pre-market hours on December 29, 2025, Mereo announced results from two Phase 3 studies for setrusumab, a treatment for conditions impacting bone metabolism.  Neither study achieved statistical significance against the primary endpoints of reduction in annualized clinical fracture rate compared to placebo or bisphosphonates, respectively.  Both studies achieved their secondary endpoints of improvements in bone mineral density against comparators (placebo and bisphosphonates) with strong statistical significance. There was no change in the safety profile observed.
