Odanacatib (MK-0822) (603139-19-1) Description:

Odanacatib, also known as MK-0822, is a selective and reversible inhibitor of cathepsin K (CatK). The cathepsin K inhibitor odanacatib (MK-0822) was shown to increase bone mineral density (BMD) and maintained normal bone strength at the spine in ovariectomized (OVX) rhesus monkeys. Odanacatib increased femoral neck (FN) BMD by 11% and 15% (p < 0.07) and ultimate load by 25% (p < 0.05) and 30% (p < 0.01) versus vehicle. Moreover, Odanacatib stimulated long-term FN and PF periosteal BFR by 3.5-fold and 6-fold with the 30 mg/kg dose versus vehicle, respectively. Odanacatib reduces bone turnover and increases bone mass in the lumbar spine of skeletally mature ovariectomized rhesus monkeys. Odanacatib was more selective than the published Cat K inhibitors balicatib and relacatib. Odanacatib (MK 0822) is currently in Phase II clinical trials.
