Description of intervention(s) / exposure
Treatment: Other - Pembrolizumab
Treatment: Drugs - Carboplatin
Treatment: Drugs - Paclitaxel
Treatment: Drugs - Docetaxel
Treatment: Other - Sacituzumab Tirumotecan

Experimental: Maintenance Treatment Arm A: Pembrolizumab + Sacituzumab Tirumotecan - During the Induction Phase, participants receive pembrolizumab 200 mg, carboplatin area under the curve (AUC) 5 (mg/mL/min), and paclitaxel 175 mg/m2 or docetaxel 75 mg/m2 on Day 1 of each 3-week cycle for 6 cycles (up to approximately 4 months).

During the Maintenance Treatment Phase, participants receive sac-TMT 4 mg/kg on Days 1, 15, and 29 of each 6-week cycle and pembrolizumab 400 mg on Day 1 of each 6-week cycle for up to 14 cycles (up to approximately 19 months).

Active comparator: Maintenance Treatment Arm B: Pembrolizumab Monotherapy - During the Induction Phase, participants receive pembrolizumab 200 mg, carboplatin AUC 5 (mg/mL/min), and paclitaxel 175 mg/m2 or docetaxel 75 mg/m2 on Day 1 of each 3-week cycle for 6 cycles (up to approximately 4 months).

During the Maintenance Treatment Phase, participants receive pembrolizumab 400 mg on Day 1 of each 6-week cycle for up to 14 cycles (up to approximately 19 months).

Experimental: Subsequent Treatment Arm A: Pembrolizumab + Sacituzumab Tirumotecan - During the Induction Phase, participants receive pembrolizumab 200 mg, carboplatin AUC 5 (mg/mL/min), and paclitaxel 175 mg/m2 or docetaxel 75 mg/m2 on Day 1 of each 3-week cycle for 6 cycles (up to approximately 4 months).

During the Subsequent Treatment Phase, participants receive sac-TMT 4 mg/kg on Days 1, 15, and 29 of each 6-week cycle until discontinuation criteria is met and pembrolizumab 400 mg on Day 1 of each 6-week cycle for up to 14 cycles (up to approximately 19 months).

Active comparator: Subsequent Treatment Arm B: Sacituzumab Tirumotecan Monotherapy - During the Induction Phase, participants receive pembrolizumab 200 mg, carboplatin AUC 5 (mg/mL/min), and paclitaxel 175 mg/m2 or docetaxel 75 mg/m2 on Day 1 of each 3-week cycle for 6 cycles (up to approximately 4 months).

During the Subsequent Treatment Phase, participants receive sac-TMT 4 mg/kg on Days 1, 15, and 29 of each 6-week cycle until discontinuation criteria is met.


Treatment: Other: Pembrolizumab
Intravenous (IV) Infusion

Treatment: Drugs: Carboplatin
During the Induction Phase, participants receive carboplatin AUC 5 (mg/mL/min) on Day 1 of each 3-week cycle for 6 cycles (up to approximately 4 months) via IV infusion.

Treatment: Drugs: Paclitaxel
During the Induction Phase, participants receive paclitaxel 175 mg/m2 on Day 1 of each 3-week cycle for 6 cycles (up to approximately 4 months) via IV infusion.

Treatment: Drugs: Docetaxel
During the Induction Phase, participants may receive docetaxel (in place of paclitaxel) 75 mg/m2 on Day 1 of each 3-week cycle for 6 cycles (up to approximately 4 months) via IV infusion.
