Arms & Interventions
Triptorelin pamoate 22.5 mg 6-month formulation
All enrolled participants will receive one intramuscular (i.m.) injection of containing 22.5 mg 6-month formulation triptorelin pamoate on Day 1.
Intervention: Triptorelin pamoate (embonate) salt
Outcomes
Primary Outcomes
Percentage of Participants Who Achieved Castrate Levels of Serum Testosterone on Day 29
Time Frame: Day 29
Blood samples were collected to determine the serum testosterone concentrations using a validated, specific and sensitive liquid chromatography tandem mass spectrometry (LC-MS/MS) method. Achievement of testosterone castration was defined as serum testosterone level \<50 nanograms per deciliter (ng/dL) or 1.735 nanomoles/liter (nmol/L). Percentages are rounded off to the tenth decimal place.
Percentage of Participants Who Maintained the Castrate Levels From Week 8 to Week 24
Time Frame: From Week 8 to Week 24
Blood samples were collected to determine the serum testosterone concentrations using a validated, specific and sensitive LC-MS/MS method. Maintenance of castration was defined as serum testosterone level \<50 ng/dL or 1.735 nmol/L.
Secondary Outcomes
- Number of Participants With Treatment-Emergent Adverse Events (TEAEs), Treatment-Emergent Serious Adverse Events (TESAEs) and Treatment-Emergent Adverse Events of Local Tolerance(From the first dose of study intervention (Day 1) up to end of study visit (Week 24), approximately 169 days)

- Area Under the Plasma Concentration Time Curve From Time 0 to the Visit on Day 169 (AUC0-169) of Triptorelin Pamoate(Pre-dose, 1, 2, 3, 4, 6, 8, 12, 24, 48, 96 and 168 hours post-dose on Day 1, Days 15, 22, 29, 57, 85, 113, 141 and 169)
