Trial Review

Did you know?

The ANZCTR now automatically displays published trial results and simplifies the addition of trial documents such as unpublished protocols and statistical analysis plans.

These enhancements will offer a more comprehensive view of trials, regardless of whether their results are positive, negative, or inconclusive.

The safety and scientific validity of this study is the responsibility of the study sponsor and investigators. Listing a study does not mean it has been endorsed by the ANZCTR. Before participating in a study, talk to your health care provider and refer to this information for consumers

Treatment: Other - IMC-F106C
Treatment: Other - Nivolumab
Treatment: Other - Nivolumab + Relatlimab

Experimental: Arm A: IMC-F106C Low Dose + Nivolumab - Participants receive IMC-F106C Low Dose once weekly (QW) for the first 12 weeks, then every 2 weeks (Q2W) through Week 51, and then every 4 weeks (Q4W) until Week 101. Nivolumab is given Q4W until Week 101.
