Amgen and UCB announced that the Food and Drug Administration (FDA) has issued a Complete Response Letter (CLR) for the Biologics License Application (BLA) for Evenity (romosozumab) for the treatment of postmenopausal women with osteoporosis

Data from the Phase 3 placebo-controlled FRAME study were included in the the original BLA submission but the FDA has requested that the safety and efficacy data from the Phase 3 active-comparator ARCH study and the Phase 3 BRIDGE study also be included in the resubmission. 

Evenity, an investigational bone-forming monoclonal antibody, is intended to inhibit sclerostin. This mechanism allows Evenity to quickly increase bone formation and decrease bone resorption at the same time.
