GTx-027 is a selective androgen receptor modulator (SARM) which was under development for or of potential interest in the treatment of breast cancer and stress urinary incontinence (SUI) but was never marketed.[2][3][1][4][5] It is taken by mouth.[1]

Description

edit

The drug is a nonsteroidal androgen receptor (AR) modulator with mixed agonistic (androgenic) and antagonistic (antiandrogenic) effects.[1][5] It has been found to reduce the growth of androgen receptor-expressing MDA-MB-231 breast cancer cells in vitro.[6][7] In addition, it has been found to increase pelvic floor muscle weight in ovariectomized female rodents.[1][8][4] The drug has been found to increase body weight, lean body mass, and muscle strength in animals as well.[9][10] In terms of chemical structure, GTx-027 is a nonsteroidal arylpropionamide SARM and is an analogue of enobosarm (ostarine; GTx-024).[1][4]

GTx-027 was first described in the scientific literature by 2013.[5][11] It is said to have either not passed preclinical research[1] or to have reached phase 1 clinical trials prior to the discontinuation of its development.[3] The drug was developed by GTx.[2][3]

After 2 weeks, the body weights of the GTx-026-treated mice were greater than those of the vehicle-treated mice, with this difference increasing in magnitude throughout the duration of the study (62% in GTx-026-treated mice vs 31% in vehicle-treated mice; P < 0.001) (Fig. 2B). GTx-026 treatment also increased lean mass (20% vs 60%; P < 0.001) compared with vehicle treatment. Consistent with the increase in lean mass, grip strength also increased in the GTx-026-treated animals (Fig. 2B). These results were reproduced with the other two SARMs, GTx-024 and GTx-027, indicating that these effects are SARM-dependent (Supplementary Material, Fig. S1B).
