75 participants in 2 patient groups

Androgen Deprivation Therapy with Docetaxel

Experimental group

Description:

All subjects in this arm will receive luteinizing hormone releasing hormone analogue (LHRHa) plus docetaxel and prednisone, as per standard of care. Triptorelin pamoate (Diphereline) 15mg will be used once per 12 weeks. Docetaxel (75 mg/m2 body surface area) will be administered as intravenous drip every 3 weeks for 6 cycles. Robot assisted radical prostatectomy will be followed in 2 weeks when 24-week treatment cycle is finished.

Treatment:

Drug: Prednisone Acetate Tablets

Drug: Docetaxel injection

Drug: Triptorelin Pamoate for Injectable Suspension

ADT alone

Active Comparator group

Description:

All subjects in this arm will receive LHRHa alone for 24 weeks before receiving robot assisted radical prostatectomy. Triptorelin Pamoate 15mg will be administered once per 12 weeks.

Treatment:

Drug: Triptorelin Pamoate for Injectable Suspension
