What to Expect as a Participant

You will actively receive the study intervention — which may be a drug, biologic, device, or procedure.

Phase 1 is the earliest stage of human testing — safety and dosage are the primary focus. Visits are frequent and medical supervision is intensive. You will be among the first people to receive this treatment.

This trial targets 120 participants in total. It began in 2024-12-04 with a primary completion date of 2025-09-04.

Brief Summary

To investigate the pharmacokinetics of triprerelin acetate for injection and triprerelin acetate (Dufferin ®) for injection of reference preparation in patients with prostate cancer by single intramusculodynamic injection in fasting state, and to evaluate the bioequivalence of the two formulations in fasting state.
