Targeted Treatment for Advanced Non-Small Cell Lung Cancer That Has Increased Copies of the MET Gene (An Expanded Lung-MAP Treatment Trial)

A Phase II Study of Amivantamab SC (Subcutaneous) in Participants With MET Amplification-Positive Stage IV or Recurrent Non-Small Cell Lung Cancer (LUNG-MAP SUB-STUDY)

This phase II Expanded Lung-MAP treatment trial tests how well amivantamab-subcutaneous (SC) works in treating patients patients with MET amplification non-small cell lung cancer. Amivantamab-SC is a drug that reduces extra copies of the MET gene, a change present in your tumor. Giving amivantamab-SC may lower the chance of the growth or spread of advanced non-small cell lung cancer that has extra copies of the MET gene in the tumor.

PRIMARY OBJECTIVE:

I. To evaluate the objective response rate (ORR) (confirmed and unconfirmed, complete and partial) in participants with MET amplification-positive non-small cell lung cancer (NSCLC) treated with amivantamab-SC within each cohort.

SECONDARY OBJECTIVES:

I. To evaluate progression-free survival (PFS) within each cohort. II. To evaluate overall survival (OS) within each cohort. III. To evaluate the duration of response among responders within each cohort. IV. To evaluate the frequency and severity of toxicities within each cohort and combined across all study participants.

TRANSLATIONAL MEDICINE OBJECTIVES:

I. To collect, process, and bank cell-free deoxyribonucleic acid (cfDNA) prior to treatment on Cycle 1 Day 1, Cycle 3 Day 1, and at first progression for future development of a proposal to evaluate comprehensive next-generation sequencing of circulating tumor deoxyribonucleic acid (ctDNA).

II. To establish a tissue/blood repository from participants with refractory non-small cell lung cancer (NSCLC).

OUTLINE:

Patients receive amivantamab subcutaneously (SC) on days 1, 8, 15, and 22 of cycle 1 and then on days 1 and 15 of subsequent cycles. Cycles repeat every 28 days in the absence of disease progression or unacceptable toxicity. Patients also undergo computerized tomography (CT) or magnetic resonance imaging (MRI) and collection of blood samples throughout the trial.

After completion of study treatment, patients are followed up for up to 3 years.

Inclusion Criteria:

• Participants must have been assigned to S1900J by the Southwest Oncology Group (SWOG) Statistics and Data Management Center (SDMC). Assignment to S1900J is determined by the LUNGMAP protocol
