Description

Wang and co-authors present a 2026 study on a drug candidate for an ultra-rare bone disease, fibrodysplasia ossificans progressiva. In this disease, a mutant receptor makes soft tissue turn to bone after injury or even on its own. The drug, BCX9250, is a small pill that blocks that receptor, called ALK2. The team tested it in binding assays, cells, and mouse models.

The drug bound strongly to both normal and mutant forms of the receptor. In cells carrying the disease mutation, it shut down the false signal that activin A wrongly triggers. Mouse tests covered both new bone growth and its return after removal. BioCryst developed the compound as an oral option for patients.
