Curator's Comment: Description was created based on several sources, including https://www.ncbi.nlm.nih.gov/pubmed/18226527 | https://www.ncbi.nlm.nih.gov/pubmed/27681784

Odanacatib is a potent, selective, and neutral cathepsin K inhibitor, an enzyme involved in bone resorption. Merck & Co was developing odanacatib, a once-weekly, oral Odanacatib, for the treatment of postmenopausal osteoporosis and osteoporosis in men. Merck & Co. has discontinued development of its cathepsin K inhibitor odanacatib, citing an increased risk of cardiovascular events for the osteoporosis drug.

Sample Use Guides

In Vivo Use Guide

Merck is conducting a long-term phase II trial that is assessing four different doses of odanacatib (3mg, 10mg, 25mg and 50mg once-weekly for 2 years) in women with postmenopausal osteoporosis (NCT00112437; EudraCT2005-001511-22). Results from this phase IIb study showed that odanacatib 50mg increased bone mineral density (BMD) from baseline, and was generally safe and well tolerated.

Route of Administration: Oral

In Vitro Use Guide

1 nM odanacatib had suppressive effects on the expression levels of inflammatory cytokines in murine RAW 264.7 cells were cultured in the presence of the receptor activator of NF-kB and lipopolysaccharide
