This came after the drug major Zydus presented its proposal for the manufacture and marketing of the drug Relugolix 120 mg tablets indicated for the treatment of adult patients with advanced prostate cancer along with bioequivalence (BE) study report and justification for the local clinical trial waiver.

Relugolix is a gonadotropin-releasing hormone (GnRH) receptor antagonist used in the treatment of several hormone-responsive conditions. It was first approved in Japan in 2019, under the brand name Relumina, for the symptomatic treatment of uterine fibroids, and more recently by the United States FDA in 2020, under the brand name Orgovyx, for the treatment of advanced prostate cancer. This branded product was later approved by the European Commission on April 29, 2022. Relugolix has also been studied in the symptomatic treatment of endometriosis.

Relugolix is an oral GnRH receptor antagonist for androgen deprivation therapy in the treatment of advanced prostate cancer. Relugolix is indicated for the treatment of adult patients with advanced prostate cancer. In a combination product with estradiol and norethindrone, relugolix is indicated for the once-daily treatment for the management of heavy menstrual bleeding associated with uterine fibroids in premenopausal women.

The mechanism of action of relugolix is as a Gonadotropin-Releasing Hormone Receptor Antagonist, Cytochrome P450 3A Inducer, Cytochrome P450 2B6 Inducer, and Breast Cancer Resistance Protein Inhibitor, P-Glycoprotein Inhibitor. The physiologic effect of relugolix is by means of Decreased GnRH Secretion.

Earlier, Medical Dialogue Team had reported about the CDSCO Panel granted permission to drug major Zydus to conduct the BE study for the anticancer drug Relugolix.
