Time frame
Assessments every 8 weeks from study day 1 for the first 24 weeks, and then every 12 weeks until disease progression, death, or initiation of subsequent treatment. Total follow-up was up to approximately 3 years.

What was measured

The primary efficacy endpoint is confirmed radiographic ORR by central IRR. ORR is defined as the percentage of patients with a confirmed CR (complete response) or PR (partial response) by mRECIST (modified Response Evaluation Criteria in Solid Tumors) v1.1/PCWG3 (Prostate Cancer Working Group 3) criteria. The confirmed response is defined as a CR or PR on subsequent tumor assessment at least 28 days after first response documentation in the absence of confirmed progression in bone. CR is disappearance of all target and non-target lesions; any pathological lymph nodes (whether target or non-target) must have reduction in short axis to \<10 mm. PR is at least a 30% decrease in the sum of the diameters of target lesions, taking as reference the baseline sum diameters.

Analysis population: IRR Efficacy Population - The IRR efficacy population is defined by measurable disease status at baseline using modified RECIST Version 1.1 criteria per independent radiology review.

Groups in this outcome
