Time frame
Duration of time from study entry to time of progression per RECIST criteria or death due to any cause, whichever occurs first. The interquartile range for follow-up was (6.37 months, 30.62 months). The maximum for follow-up was 37.85 months.

What was measured

Progression free survival (PFS) Note: For arm 2 (dMMR Cohort), the point estimate and the upper limit of the confidence interval are not able to be estimated due to insufficient events.

Analysis population: Randomized population (with determinate MMR status)

Groups in this outcome

(dMMR Cohort): Arm 1: Active Comparator (Placebo, Paclitaxel, Carboplatin)

COMBINATION PHASE: Patients receive placebo IV over 30 minutes on day 1 of each cycle, paclitaxel IV over 3 hours on day 1 of each cycle, and carboplatin IV over 30-60 minutes on day 1 of each cycle. Treatment repeats every 3 weeks for 6 cycles in the absence of disease progression or unacceptable toxicity. Patients with SD or PR who still have measurable disease may continue treatment for up to a total of 10 cycles (if deemed necessary by the treating physician) in the absence of disease progression or unacceptable toxicity. MAINTENANCE PHASE: Patients receive placebo IV over 30 minutes on day 1 of each cycle. Treatment repeats every 6 weeks for up to 14 cycles in the absence of disease progression or unacceptable toxicity.

(dMMR Cohort): Arm 2: Experimental (Pembrolizumab, Paclitaxel, Carboplatin)

COMBINATION PHASE: Patients receive pembrolizumab IV over 30 minutes on day 1 of each cycle, paclitaxel IV over 3 hours on day 1 of each cycle, and carboplatin IV over 30 minutes on day 1 of each cycle. Treatment repeats every 3 weeks for 6 cycles in the absence of disease progression or unacceptable toxicity. Patients with SD or PR who still have measurable disease may continue treatment for up to a total of 10 cycles (if deemed necessary by the treating physician) in the absence of disease progression or unacceptable toxicity. MAINTENANCE PHASE: Patients receive pembrolizumab IV over 30-60 minutes on day 1 of each cycle. Treatment repeats every 6 weeks for up to 14 cycles in the absence of disease progression or unacceptable toxicity.

(pMMR Cohort): Arm 1: Active Comparator (Placebo, Paclitaxel, Carboplatin)

Treatment repeats every 3 weeks for 6 cycles in the absence of disease progression or unacceptable toxicity. Patients with SD or PR who still have measurable disease may continue treatment for up to a total of 10 cycles (if deemed necessary by the treating physician) in the absence of disease progression or unacceptable toxicity. MAINTENANCE PHASE: Patients receive placebo IV over 30 minutes on day 1 of each cycle. Treatment repeats every 6 weeks for up to 14 cycles in the absence of disease progression or unacceptable toxicity.

(pMMR Cohort): Arm 2: Experimental (Pembrolizumab, Paclitaxel, Carboplatin)

COMBINATION PHASE: Patients receive pembrolizumab IV over 30 minutes on day 1 of each cycle, paclitaxel IV over 3 hours on day 1 of each cycle, and carboplatin IV over 30 minutes on day 1 of each cycle. Treatment repeats every 3 weeks for 6 cycles in the absence of disease progression or unacceptable toxicity. Patients with SD or PR who still have measurable disease may continue treatment for up to a total of 10 cycles (if deemed necessary by the treating physician) in the absence of disease progression or unacceptable toxicity.
