This is a randomized, open-label, active-controlled phase I trial. A total of 23 patients with locally advanced or metastatic prostate cancer who were suitable for endocrine therapy were enrolled into the screening period from D-21 to D-10 (±3d) before administration. Eligible subjects were treated with bicalutamide tablets (Casodex®, 50 mg/day) from D-10 (± 3d) to the end of the trial and randomized in a 1:1 ratio to receive LY01005 3.6 mg or ZOLADEX ® 3.6 mg after completion of pretreatment. All subjects were administered once every 28 days for three doses. Blood samples were collected at the specified time points in the trial protocol to detect PK parameters of goserelin, and PD parameters (serum testosterone, LH and FSH). Safety evaluation (including vital signs, physical examination, laboratory tests, 12 ECG, adverse events, etc.) was conducted as required in the protocol. This study aimed to compare PK/PD and safety of LY01005 and ZOLADEX® in patients with locally advanced or metastatic prostate cancer.
This is a randomized, open-label and parallel phase I study to compare pharmacokinetics (PK), pharmacodynamics (PD) and safety of goserelin acetate sustained-release microspheres for injection (LY01005) and ZOLADEX® following multiple administration in patients with prostate cancer.
