What was measured
The PSA response rate was defined as the number of participants who had at least a 50% decrease of the PSA value from the PSA reference value divided by the total number of participants evaluated (percent of participants). PSA reference value was the PSA concentration measured immediately prior to dosing on Day 1. PSA response was assessed using the Recommendations from the National Cancer Institute Prostate-Specific Antigen Working Group. A PSA response had to be confirmed at least 4 weeks after first response. 95% exact CIs were computed using the Clopper and Pearson method.
Analysis population: The PSA evaluable population was analyzed and included all HRPC participants who received complete dose(s) of nivolumab and had a baseline PSA assessment and at least one post baseline PSA assessment. A PSA evaluable participant could not have any major inclusion/exclusion violation, dosing violation, or protocol conduct violation.
Groups in this outcome
0.3 mg/kg Nivolumab
0.3 mg of nivolumab per kg of body weight was administered in a single IV infusion on Day 1 with 10% of the dose infused over 6 minutes and after a 1 hour observation period, the balance was administered over 60 minutes. Eligible participants could be re-treated and receive 2 more doses (1 dose every 4 weeks) at same dose as the single dose if: disease was stable, no drug intolerance was observed, no CR or PR was observed, or they had a positive immunogenicity sample within 4 weeks prior to re-treatment. Those who responded to therapy with a CR or PR were eligible for long-term follow-up until either PD or 2 years elapsed.
1 mg/kg Nivolumab
1 mg of nivolumab per kg of body weight was administered in a single IV infusion over 60 minutes on Day 1. Eligible participants could be re-treated and receive 2 more doses (1 dose every 4 weeks) at same dose as the single dose if: disease was stable, no drug intolerance was observed, no CR or PR was observed, or they had a positive immunogenicity sample within 4 weeks prior to re-treatment. Those who responded to therapy with a CR or PR were eligible for long-term follow-up until either PD or 2 years elapsed.
3 mg/kg Nivolumab
3 mg of nivolumab per kg of body weight was administered in a single IV infusion over 60 minutes on Day 1. Eligible participants could be re-treated and receive 2 more doses (1 dose every 4 weeks) at same dose as the single dose if: disease was stable, no drug intolerance was observed, no CR or PR was observed, or they had a positive immunogenicity sample within 4 weeks prior to re-treatment. Those who responded to therapy with a CR or PR were eligible for long-term follow-up until either PD or 2 years elapsed.
10 mg/kg Nivolumab
10 mg of nivolumab per kg of body weight was administered in a single IV infusion over 60 minutes on Day 1. Eligible participants could be re-treated and receive 2 more doses (1 dose every 4 weeks) at same dose as the single dose if: disease was stable, no drug intolerance was observed, no CR or PR was observed, or they had a positive immunogenicity sample within 4 weeks prior to re-treatment. Those who responded to therapy with a CR or PR were eligible for long-term follow-up until either PD or 2 years elapsed.
