Study Details

Study Description

Brief 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.

Will be administered subcutaneously once a month for two cycles, on day 0 and on day 28/29

Drug: Leuprolide Acetate 3.75 MG/ML
Leuprolide Acetate/ Leuprorelin is a depot injection administered as a subcutaneous injection once every month.

Outcome Measures

Primary Outcome Measures

  1. Testosterone response rate defined as Testosterone values sustained below castration level (0.5 ng/mL or 50 ng/dL) i.e. all Testosterone values at and after Day 28 until Day 57 must be < 0.5 ng/mL or < 50 ng/dL [From Day 28 to day 57]

Secondary Outcome Measures

  1. Percentage of subjects who have reached castration level of Testosterone at the last visit (Day 57) [Day 57]

  2. Percentage of breakthrough responses defined as a single total serum Testosterone value of >0.5 ng/mL or >50 ng/dL measured after achieving a castration Testosterone level [from Day 28 to Day 57]

  3. Time after first implantation until castration level of Testosterone is achieved [up to Day 28]

  4. Percentage of subjects with Testosterone values sustained below 0.2 ng/mL or 20 ng/dL at and after Day 28 until Day 57 [From Day 28 to Day 57]

  5. Change from baseline in Luteinizing hormone (LH) levels at Day 28 and 57 [from baseline to Day 28 and from baseline to Day 57]

  6. Change from baseline in Follicle Stimulating Hormone (FSH) levels at Day 28 and Day 57 [from baseline to Day 28 and from baseline to Day 57]

  7. Change from baseline in Prostate-specific antigen (PSA) at Day 57 [Day 57]

  8. Mean number of days of maintaining testosterone castration levels (mean number of castration days) [day 28 to day 57]

  9. Mean maximum testosterone concentration during the dosing period after reaching the castration level [Day 28 to Day 57]
