What was measured
PSA response was defined as a ≥ 50% reduction in PSA from baseline to the lowest postbaseline PSA value and required confirmation by a consecutive assessment at least 3 weeks later. Patients were evaluable for PSA response rate if a patient had a PSA level measured at baseline and at least one postbaseline assessment.
Analysis population: Evaluable intent to treat (ITT) population - All patients randomly assigned to treatment with PSA values at baseline and at least one postbaseline assessment.
Groups in this outcome
