Summary

This is a Randomized, Active Controlled, Comparative, Open-Label, Multi-Center, Phase 3 clinical study to compare the efficacy, safety, and pharmacokinetics of leuprolide acetate for injection 3.75mg (depot) of two brands (Luprodex and Lucrin) administered in subjects with advanced adenocarcinoma of the prostate.

Approximately 168 subjects (males )of age above 18 years fulfilling the eligibility criteria will be enrolled. The IP will be given as a monthly dose for two cycles on day 0 and day 28.

The pharmacokinetic analysis will be done for 12 patients receiving Luprodex. The primary and secondary outcomes will be captured on days as per protocol. Adverse events will be noted for safety evaluation.

• Phase: Phase 3
• Accepts Healthy Volunteers?: No

9. Had used any investigational drug, biologic, or device within five half-lives of its physiological action or three months, whichever is longer, before enrollment.

10. Anticipated to need concomitant hormonal, anti-androgen, radiotherapy, chemotherapy, immunotherapy or surgical therapy for prostate cancer throughout the duration of the study.

11. Used over-the-counter (OTC) or alternative medical therapies which has an estrogenic or anti-androgenic effect (e.g., Glycyrrhiza, Dehydroepiandrosterone (DHEA), PC-SPES, saw palmetto) within three months prior to enrollment.

21. Serious intercurrent illnesses or diseases (e.g. hematological, renal, hepatic, respiratory, endocrine, psychiatric) that might interfere with the treatment outlined in the protocol.

22. Receiving anticoagulants or antiplatelet medications and not receiving a stable dose for three months before baseline. Receiving warfarin-derivative anticoagulants with International normalized ratio (INR) outside therapeutic range for the clinical indication for which the anticoagulant has been prescribed.

23. Known hypersensitivity to GnRH, GnRH agonists or any excipients of Leuprolide (leuprorelin).

24. Positive test for HIV, HCV, HbsAg at Screening.
