Time frame
For the duration of objective response, the interquartile range is (4.24 months, 7.92 months); the maximum is 28.68 months.

What was measured

The time difference between the dates of first response and first progression; patients who do not progress are considered censored. Note: for Arm 2 (dMMR Cohort), the upper limit of the confidence interval is not able to be estimated due to an insufficient number of events.

Analysis population: Randomized patients with objective tumor response

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)

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.

(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. 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.
