What was measured
Investigator assessed maintenance PFS was defined as the time from Cycle 1 Day 1 of the maintenance phase to the date of the first documentation of PD or death due to any cause, whichever occurs first. It was defined, for participants who proceeded to maintenance phase and who did not have disease progression by investigator during the chemotherapy phase. As per RECIST version 1.1, PD was defined as at least a 20% increase in the sum of diameters of target lesions, taking as reference the smallest sum on study (this included the baseline sum if that is the smallest on study). In addition to the relative increase of 20%, the sum must have also demonstrated an absolute increase of at least 5 mm. The appearance of one or more new lesions was also considered progression. Analysis was performed using Kaplan-Meier method
Analysis population: The analysis set included randomized participants who proceeded to maintenance phase and who did not have PD by investigator assessment during the chemotherapy phase.
Groups in this outcome
Chemotherapy Followed by Avelumab
In chemotherapy phase (CP),based on investigator's decision,participants received either:paclitaxel 175 milligrams per square meter (mg/m2) intravenous (IV) infusion,followed by carboplatin dose at area under curve (AUC) 5 or 6,IV infusion (carboplatin dose (mg) = Target AUC (mg\*min/mL) x (glomerular filtration rate\[GFR\] mL/min + 25),and maximum carboplatin dose = target AUC x (150 mL/min) on Day 1 of Cycles 1 to 6; or Paclitaxel 80 mg/m2 IV infusion over 1 hour on Days 1, 8, and 15, along with carboplatin dose at AUC 5 or 6, IV infusion over 1 hour on Day 1 of Cycle 1 to 6 (1 cycle=21 days). After completion of CP, participants without evidence of disease progression, received avelumab 10 mg/kg, over 1 hour IV infusion,once every 2 weeks on Days 1, 15, and 29 (1 cycle=42 days) in maintenance phase (MP) until confirmed progressive disease,unacceptable toxicity, or withdrawal of consent, or a maximum duration of 24 months. Participants were then followed up to a maximum of 36 months.
Chemotherapy + Avelumab Followed by Avelumab
In CP, based on investigator's decision, participants received either:paclitaxel 175 mg/m2,IV,followed by carboplatin dose at AUC 5 or 6,IV (carboplatin dose \[milligrams\](mg) = Target AUC (mg\*min/mL) x GFR mL/min + 25),and maximum carboplatin dose = target AUC x (150 mL/min) on Day 1 of Cycles 1 to 6;or Paclitaxel 80 mg/m2 IV infusion over 1 hour on Days 1, 8, and 15, along with carboplatin dose at AUC 5 or 6, IV infusion over 1 hour on Day 1 of Cycle 1 to 6 along with Avelumab 10 mg/kg administered as a 1-hour IV infusion once every 3 weeks for Cycle 1 to 6 ( 1 cycle=21 days).After completion of CP, participants without evidence of disease progression, received Avelumab IV, 10 mg/kg, once every 2 weeks on Days 1, 15, and 29 ( 1 cycle=42 days) in MP until confirmed progressive disease (PD), unacceptable toxicity, or withdrawal of consent, or a maximum duration of 24 months. Participants were then followed up to a maximum of 36 months.
Chemotherapy Followed by Observation
In CP, based on investigator's decision, participants received either: paclitaxel 175 mg/m2, IV infusion, followed by carboplatin dose at AUC 5 or 6, IV infusion (carboplatin dose \[milligrams\](mg) = Target AUC \[milligrams\*minute per milliliter\] (mg\*min/mL) x GFR mL/min + 25), and maximum carboplatin dose = target AUC x (150 mL/min) on Day 1 of Cycles 1 to 6; or Paclitaxel 80 mg/m2 IV infusion over 1 hour on Days 1, 8, and 15, along with carboplatin dose at AUC 5 or 6, IV infusion over 1 hour on Day 1 of Cycle 1 to 6. Each cycle was of 21 days (3 weeks). After completion of CP, participants were followed for survival status until death or until study completion, whichever was earlier or a maximum duration of 24 months in observation phase. Participants were then followed up to a maximum of 36 months.
