What was measured

The OR is defined as the percentage of participants with at least one confirmed investigator-assessed response of CR or PR as assessed by RECIST 1.1 guidelines. The CR is defined as disappearance of all TLs and NTLs, any pathological lymph nodes (target and non-target) must have reduction in short axis \< 10 mm, and no new lesions. The PR is defined as at least a 30% decrease in the SoD of TLs (compared to baseline) and no new lesions. Confirmation of CR and PR is required by a repeat, consecutive assessment no less than 4 weeks from the date of first documentation. Percentage of participants with OR is reported. Participants who had measurable disease at baseline per the site investigator were analyzed for this outcome.

Analysis population: The FAS included all participants randomized at least 2 months before the DCO 11May2022 (i.e. on or before 11Mar2022). Participants who had measurable disease at baseline per the site investigator were analyzed for this outcome.

Groups in this outcome

Monalizumab 750 mg Q2W + Cetuximab 400 mg/m^2

Participants received IV monalizumab 750 mg Q2W and IV cetuximab 400 mg/m\^2 initial dose followed by 250 mg/m\^2 Q1W until disease progression, unacceptable toxicity, withdrawal of consent, or another discontinuation criterion was met.

Placebo Q2W + Cetuximab 400 mg/m^2

Participants receieved IV placebo matched to monalizumab Q2W and IV cetuximab 400 mg/m\^2 initial dose followed by 250 mg/m\^2 Q1W until disease progression, unacceptable toxicity, withdrawal of consent, or another discontinuation criterion was met.

    The analysis was performed using a logistic regression model, with treatment as a covariate and adjusting for HPV Status, WHO/ECOG PS, and number of lines of prior therapy in the R/M setting with 95% CI calculated by profile likelihood.
