Treatment: Drugs - Brenetafusp
Treatment: Drugs - Nivolumab
Treatment: Drugs - Nivolumab + Relatlimab
Experimental: Arm A: Brenetafusp Low Dose + Nivolumab - Participants receive brenetafusp Low Dose once weekly (QW) for the first 13 weeks, then every 2 weeks (Q2W) through Week 51, and then every 4 weeks (Q4W). Nivolumab is given Q4W.

Association between PFS and Intra-Tumor Immune Cells
Query!
Assessment method [8]
0
0
The potential association between the effect of IMC-F106C on efficacy and intra-tumor environment will be explored. Intra-tumor environment is estimated as the ratio of CD3+ to CD163+ cells and the correlation with PFS will be estimated by the hazard ratio (+/- 95% CI) from a Cox model. This analysis will be restricted to subjects randomized to receive IMC-F106C.
