Study Arms:
- Arm A (Atezolizumab + Carboplatin or Cisplatin + Pemetrexed (Type: EXPERIMENTAL): Participants received intravenous (IV) infusion of 1200 milligrams (mg) of atezolizumab on Day 1 every 3 weeks (q3w), IV infusion of 500 milligrams per meter square (mg/m\^2) pemetrexed on Day 1 q3w, and as per investigator's choice either IV infusion of carboplatin on Day 1 q3w with a dose calculated using 'Calvert formula' to obtain area under concentration versus time (AUC) = 6 milligrams per milliliter per minute (mg/mL/min) or IV infusion of 75 mg/m\^2 cisplatin q3w on Day 1 q3w, during induction dosing period of 4 or 6 cycles (Cycle length=21 days). Participants who experienced clinical benefit during the induction phase began maintenance therapy. Participants will receive IV infusion of 1200 mg of atezolizumab and 500 mg/m\^2 of pemetrexed on Day 1 q3w until disease progression in the maintenance period.
- Arm B (Carboplatin or Cisplatin + Pemetrexed) (Type: ACTIVE_COMPARATOR): Participants received IV infusion of 500 mg/m\^2 pemetrexed on Day 1 q3w, and as per investigator's choice of either IV infusion of carboplatin on Day 1 q3w with a dose calculated using 'Calvert formula' to obtain AUC =6 mg/mL/min or IV infusion of 75 mg/m\^2 cisplatin q3w on Day 1 q3w, during induction dosing period for 4 or 6 cycles (Cycle length=21 days). Participants who did not experience disease progression during the induction phase began maintenance therapy. Participants will receive IV infusion of 500 mg/m\^2 of pemetrexed on Day 1 q3w until disease progression in the maintenance period.
