Research and Markets: GTX's Ostarine for Cancer Cachexia - a Debilitating Condition in Need of Therapy

DUBLIN--(BUSINESS WIRE)-- Research and Markets ( has announced the addition of the "GTX's Ostarine for cancer cachexia - a debilitating condition in need of therapy" report to their offering.

Ostarine is a small molecule, orally available, selective androgen receptor modulator (SARM) in phase III trials for use in cancer cachexia. GTX believes that Ostarine has the ability to build muscle mass and bone in patients with this debilitating condition. In so doing they hope to improve the ability to tolerate chemotherapy and perhaps even survival (although the latter is not a requirement for approval). The two phase III power trials are targeting a population with non-small cell lung cancer (NSCLC) who are about to begin two slightly different regimens of first-line chemotherapy. This report explores the strengths and weaknesses of the phase II data as it relates to the probability of phase III success, regulatory precedents as well as the market for therapies that target this condition.

Key Topics Covered:


1. Cancer cachexia


1. Preclinical data provide a rationale for use
