Groups2
Neither group, or both, names a comparator, so the groups keep ClinicalTrials.gov's order.
| Group | Title | Description | With the outcome | Analysed | ClinicalTrials.gov code |
|---|---|---|---|---|---|
| Group 1 | Arm A (LHRHa, Apalutamide) | Participants receive gonadotropin-releasing hormone analog (leuprolide, goserelin, or triptorelin as determined by treating physician) IM once every 3 months and apalutamide PO QD. Treatment repeats every 28 days for up to 6 cycles in the absence of disease progression or unacceptable toxicity. Beginning no less than 48 hours after completion of therapy, participants undergo radical prostatectomy. | 13 | 32 | OG000 |
| Group 2 | Arm B (LHRHa, Apalutamide, Abiraterone Acetate) | Participants receive gonadotropin-releasing hormone analog and apalutamide as in arm A, abiraterone acetate PO QD, and prednisone PO QD. Treatment repeats every 28 days for up to 6 cycles in the absence of disease progression or unacceptable toxicity. Beginning no less than 48 hours after completion of therapy, participants undergo radical prostatectomy. | 12 | 31 | OG001 |
