Study Endpoints

Primary Endpoints

Incidence of adverse events
Up to 2 years

Evaluated according to National Cancer Institute Common Terminology Criteria for adverse events (NCI CTCAE) version (v)5.0. Will be summarized by cohort and grade using frequencies and relative frequencies.

Objective response rate (ORR)
Up to 2 years

Will be summarized by cohort (with or without CDX 1140) using frequencies and relative frequencies, with the ORR estimated using 90% confidence intervals obtained by Jeffrey's prior method. The final analysis will be performed on all n=80 (40 in each cohort) evaluable patients; and if the p-value is less than or equal to 0.10, then the triplet regimen will be considered superior with respect to response.

Secondary Endpoints

Progression free survival (PFS)
From first day of treatment until disease progression or date of death from any cause, assessed up to 2 years
Overall survival (OS)
From first day of treatment until disease progression or date of death from any cause, assessed up to 2 years
Disease control rate (DCR)
Up to 2 years
