What was measured

Change from baseline in GHS/QoL score using the EORTC QLQ-C30 will be determined. The EORTC QLQ-C30 is the most widely used cancer-specific, health-related QoL instrument comprised of 30 individual items arranged as both multi-item scales and individual items. Specifically, these items are divided into 5 functional scales (15 items total), 3 symptom scales (7 items total), 6 individual items, and a GHS/QoL scale composed of 2 items: GHS and QoL. The GHS/QoL score measured here refers to only the composite score calculated for the GHS/QoL scale. Both items on the GHS/QoL scale are scored from 1 (very poor GHS/QoL) to 7 (excellent GHS/QoL) and scores for both items are averaged and a linear transformation applied to standardize the overall GHS/QoL score from 0 to 100, with higher overall scores indicating higher GHS/QoL.

Analysis population: All randomized participants who received at least one dose of study treatment and have at least one EORTC-QLQ-C30 Item 30 assessment data available.

Groups in this outcome

NAC + Neoadjuvant/Adjuvant Pembrolizumab

Neoadjuvant: Prior to surgery, participants receive up to 4 cycles (cycle length: 3 weeks) of pembrolizumab \[200 mg, intravenous (IV); given on cycle day 1\] in combination with platinum doublet neoadjuvant chemotherapy (NAC), consisting of cisplatin \[75 mg/m\^2, IV; given on cycle day 1\] and either Gemcitabine \[1000 mg/m\^2, IV; given on cycle days 1 and 8\] or Pemetrexed \[500 mg/m\^2, IV; given on cycle day 1\]. Adjuvant: 4-12 weeks following surgery, participants receive 13 cycles (cycle length: 3 weeks) of pembrolizumab \[200 mg, IV; given on cycle day 1\].

NAC + Neoadjuvant/Adjuvant Placebo

Neoadjuvant: Prior to surgery, participants receive up to 4 cycles (cycle length: 3 weeks) of placebo \[normal saline, IV; given on cycle day 1\] in combination with platinum doublet NAC, consisting of cisplatin \[75 mg/m\^2, IV; given on cycle day 1\] and either Gemcitabine \[1000 mg/m\^2, IV; given on cycle days 1 and 8\] or Pemetrexed \[500 mg/m\^2, IV; given on cycle day 1\]. Adjuvant: 4-12 weeks following surgery, participants receive 13 cycles (cycle length: 3 weeks) of placebo \[normal saline, IV; given on cycle day 1\].
