Time frame
From randomization to the first documented response (CR or PR) and progression (up to approximately 65 months)

What was measured

The time between the first documented response (Complete response (CR) or partial response (PR)) and progression or death, per RECIST 1.1 by blinded independent central review (BICR) assessment. (Based on Kaplan-Meier Estimates) Complete Response (CR): Disappearance of all target lesions. Any pathological lymph nodes (whether target or non-target) must have reduction in short axis to \< 10 mm. Partial Response (PR): At least a 30% decrease in the sum of diameters of target lesions, taking as reference the baseline sum diameters.

Analysis population: All randomized participants and randomized PD-L1 CPS \>= 20 participants with a BOR response of CR or PR

Groups in this outcome

Nivolumab + Ipilimumab

Nivolumab 3 mg/kg IV every 2 weeks + Ipilimumab 1 mg/kg IV every 6 weeks until progression, unacceptable toxicity, or a maximum of 24 months from first nivolumab treatment.

EXTREME Regimen

Cetuximab 400 mg/m2 IV for the initial dose only, then 250 mg/m2 weekly + cisplatin (100mg/m2) or carboplatin (AUC of 5 mg per milliliter per minute) on Day 1 and fluorouracil (1000 mg/m2 per day for 4 days) every 3 weeks for maximum of 6 cycles followed by maintenance cetuximab at 250 mg/m2 weekly (or every 2 weeks, per local prescribing information) until disease progression or unacceptable toxicity; the choice of cisplatin or carboplatin is at the discretion of the investigator.
