Clinical Details

Official title: Pharmacokinetic, Safety and Efficacy Study of a Six-Month Depot Formulation of Leuprolide in Subjects With Prostatic Carcinoma

Study design: Allocation: Non-Randomized, Endpoint Classification: Safety/Efficacy Study, Intervention Model: Single Group Assignment, Masking: Open Label, Primary Purpose: Treatment

Primary outcome: Suppression of serum testosterone (<=50 ng/dL) and maintenance of serum testosterone suppression once suppression is achieved for individual subjects.

Secondary outcome:

Change from baseline in Eastern Cooperative Oncology Group (ECOG) performance status.

Change from baseline in symptom severity (bone pain, pain on urination, urination difficulty).
