Arm | Intervention/treatment |
---|---|
Experimental: avutometinib (VS-6766)+sotorasib
To determine the recommended phase 2 dose (RP2D) for avutometinib (VS 6766) in combination with sotorasib in G12C inhibitor naïve and exposed patients

The RP2D of avutometinib(VS-6766) + sotorasib determined in Part A will be used in Part B dose expansion
Other Names:
|
Experimental: avutometinib (VS-6766)+sotorasib - G12C inhibitor naïve
To determine the efficacy of the RP2D identified from Part A in G12C inhibitor naïve patients
|
Drug: avutometinib (VS-6766) and sotorasib
The RP2D of avutometinib(VS-6766) + sotorasib determined in Part A will be used in Part B dose expansion

To determine the efficacy of the RP2D identified from Part A in G12C inhibitor exposed patients
|
Drug: avutometinib (VS-6766) and sotorasib
The RP2D of avutometinib(VS-6766) + sotorasib determined in Part A will be used in Part B dose expansion
Other Names:
|
- Part A: To determine RP2D for avutometinib(VS-6766) in combination with sotorasib [ Time Frame: From start of treatment to confirmation of RP2D; 28 days ]Assessment of Dose-limiting toxicities (DLTs)
