Overview
11 DESCRIPTION Romosozumab-aqqg is a humanized monoclonal antibody (IgG2) produced in a mammalian cell line (Chinese Hamster Ovary) by recombinant DNA technology that binds to and inhibits sclerostin. Romosozumab-aqqg has an approximate molecular weight of 149 kDa. EVENITY (romosozumab-aqqg) injection is supplied as a sterile, preservative-free, clear to opalescent, colorless to light yellow...
Mechanism of Action
12 CLINICAL PHARMACOLOGY 12.1 Mechanism of Action EVENITY inhibits the action of sclerostin, a regulatory factor in bone metabolism. EVENITY increases bone formation and, to a lesser extent, decreases bone resorption. Animal studies showed that romosozumab-aqqg stimulates new bone formation on trabecular and cortical bone surfaces by stimulating osteoblastic activity resulting in increases in trabecular and cortical bone mass and improvements in bone structure and strength [see Nonclinical Toxicology (13.2) and Clinical Studies (14.1) ] . 12.2 Pharmacodynamics In postmenopausal women with osteoporosis, EVENITY increased the bone formation marker procollagen type 1 N-telopeptide (P1NP) with a peak increase from baseline of approximately 145% compared to placebo 2 weeks after initiating...
