Brief Summary:
This phase II ComboMATCH treatment trial tests how well AMG 510 (sotorasib) with or without panitumumab works in treating patients with KRAS G12C mutant solid tumors that may have spread from where it first started to nearby tissue, lymph nodes, or distant parts of the body (advanced). Sotorasib is in a class of medications called KRAS inhibitors. It works by blocking the action of the abnormal protein that signals cancer cells to multiply. This helps stop or slow the spread of cancer cells. Panitumumab is in a class of medications called monoclonal antibodies. It works by slowing or stopping the growth of cancer cells. Giving combination panitumumab and sotorasib may kill more tumor cells in patients with advanced solid tumors with KRAS G12C mutation.

Primary Outcome Measures :
  1. Progression-free survival (PFS) (Cohort I) [ Time Frame: From registration to documented disease progression or death from any cause, assessed up to 3 years ]
    PFS will be compared between the arms using a one-sided log rank test with 10% type I error. Cox's proportional hazards model will be used to estimate the PFS hazard ratio between the treatment arms and a two-sided 80% confidence interval will be reported (to correspond to the one-sided 10% type I error). Confidence intervals on most other quantities will use the two-sided 90% level.

  2. Best objective response (Cohort II) [ Time Frame: From the start of the treatment until disease progression/recurrence, assessed up to 3 years ]
    Will be evaluated using the criteria defined by Response Evaluation Criteria in Solid Tumors (RECIST]) version 1.1 for patients with solid tumors.

  3. Overall response rate (ORR) (Cohort II) [ Time Frame: From the time measurement criteria are met for complete response (CR) or partial response (PR) (whichever is first recorded) until the first date that recurrent or progressive disease is objectively documented, assessed up to 3 years ]
    The exact 90% confidence interval on the ORR (determined using the method of Atkinson and Brown) will be reported. If the number of analyzable cases is less than 35, a 5% one-sided test will still be used.


Secondary Outcome Measures :
  1. Overall survival (OS) (Cohort I) [ Time Frame: Up to 3 years ]
    OS distributions by treatment will be estimated and 90% confidence intervals on estimated rates at 6 and 12 months will be reported. The OS hazard ratio will be estimated using Cox proportional hazards model and a 90% confidence interval reported.

  2. ORR (Cohort I) [ Time Frame: Up to 3 years ]
    Will be compared using Fisher's exact test and exact 90% confidence intervals for the rates in each arm will be computed.

  3. Disease control rates (Cohort I) [ Time Frame: From the start of the treatment until the criteria for progression are met, assessed up to 3 years ]
    Will be compared using Fisher's exact test and exact 90% confidence intervals for the rates in each arm will be computed.

  4. PFS (Cohort II) [ Time Frame: At 6 and 12 months, assessed up to 3 years ]
    Will be estimated and 90% confidence intervals on estimated rates will be reported.

  5. OS (Cohort II) [ Time Frame: At 6 and 12 months, assessed up to 3 years ]
    Will be estimated and 90% confidence intervals on estimated rates will be reported.
