Arms & Interventions
Safety Run-in Period: Autogene Cevumeran + Pembrolizumab
Participants will receive at least one cycle of 200 mg pembrolizumab monotherapy by intravenous (IV) infusion followed by 200 mg pembrolizumab IV infusion every 3 weeks (Q3W) plus a recommended dose of autogene cevumeran.
Intervention: Autogene cevumeran
Safety Run-in Period: Autogene Cevumeran + Pembrolizumab
Participants will receive at least one cycle of 200 mg pembrolizumab monotherapy by intravenous (IV) infusion followed by 200 mg pembrolizumab IV infusion every 3 weeks (Q3W) plus a recommended dose of autogene cevumeran.
Intervention: Pembrolizumab
Randomized Period: Arm A: Pembrolizumab
Participants will receive 200 mg pembrolizumab administered by IV infusion Q3W. Participants in Arm A have the option to cross over to combination treatment with autogene cevumeran plus pembrolizumab (Arm B) after confirmed disease progression.
Intervention: Pembrolizumab
Randomized Period: Arm B: Autogene Cevumeran + Pembrolizumab
Participants will receive at least one cycle of 200 mg pembrolizumab monotherapy by IV infusion followed by 200 mg pembrolizumab IV infusion Q3W plus a recommended dose of autogene cevumeran.
Intervention: Autogene cevumeran
Randomized Period: Arm B: Autogene Cevumeran + Pembrolizumab
Participants will receive at least one cycle of 200 mg pembrolizumab monotherapy by IV infusion followed by 200 mg pembrolizumab IV infusion Q3W plus a recommended dose of autogene cevumeran.
Intervention: Pembrolizumab
Outcomes
Primary Outcomes
Progression-free Survival (PFS) According to Response Evaluation Criteria in Solid Tumors, Version 1.1 (RECIST v.1.1) After Randomization
Time Frame: From randomization to PD or death (up to approximately 60 months)
PFS was defined as the time from randomization to the first documented PD as determined by the investigator according to RECIST v1.1 or death from any cause, whichever occurred first. PD was defined as at least a 20% increase in the sum of diameters (SOD) of target lesions, taking as reference the smallest sum on study (nadir), including baseline. In addition to the relative increase of 20%, the sum must also demonstrate an absolute increase of at least 5 millimeters (mm). Kaplan-Meier (KM) method was used to estimate median PFS.
Secondary Outcomes
- Objective Response Rate (ORR) According to RECIST V.1.1 After Randomization(Up to approximately 60 months)
- Overall Survival (OS) After Randomization(From randomization to death (up to approximately 63 months))
- Duration of Response (DOR) According to RECIST V.1.1 After Randomization(Up to approximately 60 months)
- Change From Baseline in Global Health Status (GHS)/Health-related Quality of Life (HRQoL) Score Assessed by European Organisation for Research and Treatment of Cancer 30-Item Quality of Life Questionnaire (EORTC QLQ-C30)(Baseline, Day 1 of Cycles 1 to 34, time of first PD, time to last dose, treatment discontinuation and study drug completion (up to approximately 29 months) (1 cycle = 21 days))
- ORR According to RECIST V.1.1 After Crossover(Up to 54.7 months)
- Number of Participants With Adverse Events (AEs)(Baseline up to 90 days after the final dose of study drug (Safety run-in and randomized stage: up to 32 months; Cross-over stage: up to 24 months))
