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The ANZCTR now automatically displays published trial results and simplifies the addition of trial documents such as unpublished protocols and statistical analysis plans.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

Experimental: Arm 3 - Participants will receive alternate formulation of MK-1084 until progressive disease or discontinuation. Dosing regimen may be adjusted based on safety.

Experimental: Arm 4 - Participants will receive MK-1084 daily oral dose plus an intravenous infusion of pembrolizumab (200 mg) once every 21-day cycle for up to 35 cycles (up to \~24 months). Participants will also receive carboplatin (per label) and pemetrexed (per label) once every 21-day cycle for the first 4 cycles.

Experimental: Arm 5 - Participants will receive MK-1084 daily oral dose plus an intravenous infusion of cetuximab (per label) every 2 weeks of each 28-day cycle.

Experimental: Arm 6 - Participants will receive MK-1084 daily oral dose. Additionally, participants receive an intravenous infusion of cetuximab (per label) every 2 weeks of each 28-day cycle, oxaliplatin (per label) for first 6 cycles, and leucovorin (per label) and 5-fluorouracil (per label) once every 14-days.
