Description: Ostarine, aslo known as Enobosarm, and MK-2866 and GTX-024, is selective androgen receptor modulator with anabolic activity. Selective androgen receptor modulator (SARM) GTx-024 is designed to work like testosterone, thus promoting and/or maintaining libido, fertility, prostate growth, and muscle growth and strength. Mimicking testosterone's action, this agent may increase lean body mass, thereby ameliorating muscle wasting in the hypermetabolic state of cancer cachexia.

Additional Information

Ostarine (also known as GTx-024 and MK-2866) is an investigational selective androgen receptor modulator (SARM) from GTX, Inc for treatment of conditions such as muscle wasting and osteoporosis, formerly under development by Merck & Company.  GTx and Merck had clinical development plans to evaluate Ostarine for the treatment of muscle loss in patients with COPD and for the treatment of chronic sarcopenia. They had a goal of initiating an Ostarine Phase II COPD clinical trial in the first quarter of 2010 and an Ostarine Phase IIb chronic sarcopenia clinical trial in 2010.
