Description: Macimorelin, also known as AEZS-130, EP-1572, or JMV1843, is a novel synthetic small molecule, acting as a ghrelin agonist, that is orally active and stimulates the secretion of growth hormone (GH). Based on results of Phase 1 studies, AEZS-130 has potential applications for the treatment of cachexia, a condition frequently associated with severe chronic diseases such as cancer, chronic obstructive pulmonary disease and AIDS. In addition to the therapeutic application, a Phase 3 trial with AEZS-130 as a diagnostic test for growth hormone deficiencies in adults has been completed.

Additional Information

AEZS-130 (EP-1572) is a novel peptidomimetic growth hormone secretagogues (GHS) which represent a new class of pharmacological agents which have the potential to be used in numerous clinical applications. They include treatment for growth retardation in children and cachexia associated with chronic disease such as AIDS and cancer.
Following the successfull Phase 3 trial results in AGHD, for which orphan-drug status had been granted by the FDA in 2007, the Company expects to file a new drug application (NDA) in 2012. (source:
