Treatment: Other - vibostolimab
Treatment: Other - pembrolizumab
Treatment: Drugs - pemetrexed
Treatment: Drugs - carboplatin
Treatment: Other - pembrolizumab/vibostolimab coformulation
Treatment: Drugs - cisplatin
Treatment: Drugs - etoposide

Experimental: vibostolimab - During an initial dose evaluation phase, participants will receive Dose A, B, C, D, E, or F of vibostolimab on Day 1 of each 21-day infusion cycle (for a maximum of 35 cycles) until the RPTD has been established. The RPTD will be established based on the number of dose limiting toxicities (DLTs) at each dose level. Once the RPTD is established, participants will continue receiving the RPTD of vibostolimab on Day 1 of each 21-day infusion cycle until the 35-cycle limit is reached.

Experimental: vibostolimab + pembrolizumab - During an initial dose evaluation phase, participants will receive Dose A, B, C, D, E, or F of vibostolimab in combination with 200 mg pembrolizumab on Day 1 of each 21-day infusion cycle (for a maximum of 35 cycles) until the RPTD of vibostolimab has been established. The RPTD will be established based on the number of DLTs at each dose level. Once the RPTD of vibostolimab is established, participants will continue receiving the RPTD of vibostolimab in combination with 200 mg pembrolizumab on Day 1 of each 21-day infusion cycle until the 35-cycle limit is reached.

Experimental: Advanced solid tumor cohort - Participants will receive the RPTD of vibostolimab monotherapy or the RPTD of vibostolimab in combination with 200 mg pembrolizumab on Day 1 of each 21-day infusion cycle until the 35-cycle limit is reached.

Experimental: Randomized dose 1 comparison cohort - Participants will be randomized to receive a fixed dose (Dose 1) of vibostolimab in combination with 200 mg pembrolizumab on Day 1 of each 21-day infusion cycle until the 35-cycle limit is reached.

Experimental: Randomized dose 2 comparison cohort - Participants will be randomized to receive a fixed dose (Dose 2) of vibostolimab in combination with 200 mg pembrolizumab on Day 1 of each 21-day infusion cycle until the 35-cycle limit is reached.

Experimental: vibostolimab +pembrolizumab+pemetrexed+carboplatin - Participants will receive a fixed dose of vibostolimab in combination with 200 mg pembrolizumab, 500 mg/m\^2 pemetrexed, and Area Under Curve (AUC) 5 mg/mL/min carboplatin on Day 1 of each 21-day infusion cycle for up to 4 cycles followed by maintenance therapy with a fixed dose of vibostolimab in combination with 200 mg pembrolizumab and 500 mg/m\^2 pemetrexed on Day 1 of each 21-day infusion cycle for up to an additional 31 cycles.

Experimental: vibostolimab Dose 1 Japanese cohort - Japanese participants will be randomized to receive a fixed dose (Dose 1) of vibostolimab in combination with 200 mg pembrolizumab on Day 1 of each 21-day infusion cycle until the 35-cycle limit is reached.

Experimental: vibostolimab Dose 2 Japanese cohort - Japanese participants will be randomized to receive a fixed dose (Dose 2) of vibostolimab in combination with 200 mg pembrolizumab on Day 1 of each 21-day infusion cycle until the 35-cycle limit is reached.

Experimental: pembrolizumab/vibostolimab coformulation - Participants will receive a fixed dose of pembrolizumab/vibostolimab coformulation, consisting of 200 mg of pembrolizumab + 200 mg vibostolimab, on Day 1 of each 21-day infusion cycle for up to 35 cycles.

Experimental: vibostolimab+pembrolizumab+carboplatin OR cisplatin+etoposide - Participants will receive 200 mg vibostolimab in combination with 200 mg pembrolizumab, plus the investigator's choice of Area Under Curve (AUC) 5 mg/mL/min carboplatin OR 75 mg/m\^2 cisplatin on Day 1 of each 21-day cycle plus 100 mg/m\^2/day etoposide on Days 1-3 of each 21-day cycle for up to 4 cycles. Maintenance therapy with 200 mg vibostolimab in combination with 200 mg pembrolizumab on Day 1 of each 21-day cycle will continue for up to an additional 31 cycles. A participant will be allowed to switch from cisplatin to carboplatin in the event of an adverse event (AE), ineligibility for further cisplatin therapy, and/or the investigator considers switching to carboplatin to be in the best interest of the participant.

Experimental: pembrolizumab/vibostolimab coformulation China cohort - Participants from mainland China will receive a fixed dose of pembrolizumab/vibostolimab coformulation, consisting of 200 mg of pembrolizumab + 200 mg vibostolimab, on Day 1 of each 21-day infusion cycle for up to 35 cycles.
