Testing the Use of Targeted Treatment (AMG 510) for KRAS G12C Mutated Advanced Non-squamous Non-small Cell Lung Cancer (A Lung-MAP Treatment Trial)

Study Overview
=================
Brief Summary
-----------------
This phase II Lung-MAP treatment trial studies the effect of AMG 510 in treating non-squamous non-small cell lung cancer that is stage IV or has come back (recurrent) and has a specific mutation in the KRAS gene, known as KRAS G12C. Mutations in this gene may cause the cancer to grow. AMG 510, a targeted treatment against the KRAS G12C mutation, may help stop the growth of tumor cells.

Detailed Description
-----------------
PRIMARY OBJECTIVE: I. To evaluate the response rate (confirmed, complete or partial) of AMG 510 in participants with KRAS^G12C mutated stage IV or recurrent non-squamous non-small cell lung cancer (NSCLC). SECONDARY OBJECTIVES: I. To evaluate investigator assessed progression-free survival (IA-PFS) within each cohort. II. To evaluate overall survival (OS) within each cohort. III. To evaluate duration of response (DOR) among responders within each cohort. IV. To evaluate the frequency and severity of toxicities within the full study population (all cohorts combined). TRANSLATIONAL MEDICINE OBJECTIVES: I. To evaluate the association between clinical outcomes (response, IA-PFS, OS) and other co-mutations (e.g., CDKN2A/B/C, ATM, PIK3CA) identified by the Foundation Medicine Inc (FMI) FoundationOne CDx from LUNGMAP, within cohorts and across the full study population of KRAS^G12C positive participants. II. To evaluate the association between clinical outcomes (response, IA-PFS, OS) and PD-L1 total proportion score determined by screening in LUNGMAP, within cohorts and across the full study population of KRAS^G12C positive participants. III. To evaluate the association between clinical outcomes (response, IA-PFS, OS) and Tumor Mutational Burden Score determined by the FMI FoundationOne CDx from LUNGMAP, within cohorts and across the full study population of KRAS^G12C positive participants. IV. To collect, process, and bank cell-free deoxyribonucleic acid (cfDNA) at pre-treatment on cycle 1 day 1, cycle 2 day 1, cycle 3 day 1, and at progression for future development of a proposal to evaluate comprehensive next-generation sequencing of circulating tumor DNA (ctDNA) and association with clinical outcomes. Note: The translational medicine proposal to use these specimens will be submitted as a revision to CTEP for approval, prior to the SWOG Statistical and Data Management Center (SDMC) review of assay results. OUTLINE: Patients receive AMG 510 orally (PO) once daily (QD) on days 1-21. Cycles repeat every 21 days in the absence of disease progression or unacceptable toxicity. After completion of study treatment, patients are followed up every 3 months for 3 years if the disease has not gotten worse at the time of finishing study treatment. If the disease has gotten worse, patients are followed up every 6 months for 2 years, then at the end of the 3 years from the time they go on study.

Eligibility Criteria
-----------------
Inclusion Criteria: Participants must be assigned to S1900E. Assignment to S1900E is determined by the LUNGMAP protocol genomic profiling using the FoundationOne assay. Biomarker eligibility for S1900E is based on the identification of a KRAS^G12C mutation Participants must have confirmed stage IV or recurrent non-squamous non-small cell lung cancer (NSCLC). Mixed histology NSCLC with less than 50% squamous component is allowed Participants must have measurable disease documented by computed tomography (CT) or magnetic resonance imaging (MRI).

Participants with uteri must have agreed to use an effective contraceptive method for at least one month after the last dose of AMG 510. Participants with sperm must have agreed to use an effective contraceptive method for at least 3 months after the last dose of AMG 510. Participants are considered to be of reproductive potential if they have had menses at any time in the preceding 12 consecutive months and no prior oophorectomy and/or hysterectomy. In addition to routine contraceptive methods, effective contraception for participants with uteri also includes heterosexual celibacy and surgery intended to prevent pregnancy (or with a side-effect of pregnancy prevention) defined as a hysterectomy, bilateral oophorectomy or bilateral tubal ligation. Acceptable methods of birth control for participants with sperm include sexual abstinence (refraining from heterosexual intercourse); vasectomy with testing showing there is no sperm in the semen; bilateral tubal ligation or occlusion in the partner; or a condom (the female partner should also consider a form of birth control). However, if at any point a previously celibate participant chooses to become heterosexually active during the time period for use of contraceptive measures outlined in the protocol, he/she is responsible for beginning contraceptive measures
