Completed

• Conditions: Prostate carcinoma

• Registration Number: CTRI/2014/01/004325
• Lead Sponsor: Daewoong Pharmaceuticals Co Ltd

Brief Summary

This study is Multicentric, Open-Label, Randomized, Three-Treatment, Parallel, Single-Dose Clinical Bioequivalence Study of Subcutaneous Leuprolide Acetate 11.25 mg (Luphere Depot®)-Test 1 (T1) and Leuprolide Acetate 11.25 mg (Luphere Depot®) –Test 2 (T2) of Daewoong pharmaceuticals Co. Ltd., in comparison with Leuprolide Acetate 11.25 mg (Lucrin Depot®) – Reference (R) of Takeda Pharmaceutical Company Ltd., in Male Prostatic Carcinoma Subjects Undergoing Initial Therapy. xml:namespace prefix = o ns = "urn:schemas-microsoft-com:office:office" /

The Primary objective will be to determine clinical bioequivalence of test drug (T1 & T2) with the active comparator (reference drug). The secondary objective of the study is to monitor the adverse events, to ensure safety and tolerability as assessed by reported adverse events, laboratory, clinical investigations and vital signs in the prostate carcinoma patients.
