简要总结
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.
详细描述
PRIMARY OBJECTIVES:
I. To evaluate the efficacy of the combination of AMG 510 (sotorasib) and panitumumab as compared to AMG 510 (sotorasib) alone in patients with advanced/metastatic KRAS G12C mutated solid tumors (except colorectal carcinoma [CRC] and non-small cell lung carcinoma [NSCLC]) as measured by progression free survival (Cohort 1).
II. To evaluate the efficacy of the combination of AMG 510 (sotorasib) and panitumumab in patients with advanced/metastatic KRAS G12C mutated solid tumors that have progressed on a prior KRAS G12C inhibitor as measured by response rate (Cohort 2).
SECONDARY OBJECTIVES:
I. To evaluate the efficacy of the combination of AMG 510 (sotorasib) and panitumumab as compared to AMG 510 alone in patients with advanced/metastatic KRAS G12C mutated solid tumors (except CRC and NSCLC) as measured by response rate, disease control rate, and overall survival (Cohort 1).

结局指标
主要结局
Progression-free survival (PFS) (Cohort I)
时间窗: 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.
Best objective response (Cohort II)
时间窗: 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) version 1.1 for patients with solid tumors.

Overall response rate (ORR) (Cohort II)
时间窗: From the time measurement criteria are met for complete response or partial response (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.
