Mechanism of action

BMN 111 mimics the action of C-type natriuretic peptide, a naturally occurring hormone that signals through NPR-B receptors in the growth plate cartilage. By activating this pathway, the drug stimulates endochondral ossification and longitudinal bone growth, thereby increasing adult height. This mechanism addresses the underlying pathophysiology of skeletal dysplasias characterized by impaired bone growth.
