Additional Relevant Details The company is discontinuing the development of odanacatib, Merck’s investigational cathepsin K inhibitor for osteoporosis, and will not seek regulatory approval for its use. Merck previously reported a numeric imbalance in adjudicated stroke events in the pivotal Phase 3 fracture outcomes study in postmenopausal women. The company has decided to discontinue development after an independent adjudication and analysis of major adverse cardiovascular events confirmed an increased risk of stroke. The data from the analysis will be presented at the American Society for Bone Mineral Research (ASBMR) in September.
