In part I, 33 patients with metastatic NSCLC with: a) NR-VAF but b) without radiographic progression of disease, will be treated with LAT to determine if ablation to all sites of disease leads to acceptable rates of mean VAF reduction, thus indicating a discernible molecular/clinical response in this subgroup of patients with metastatic disease.

If the appropriate criteria are met in part I,, in part II 60 patients with NR-VAF but without radiographic progression of disease will be randomized to one of two arms: continuation of systemic therapy (standard of care) vs. ablation to all sites of disease (experimental arm), with a primary endpoint of progression free survival.

Local ablative therapy

Participants will undergo ctDNA collection in conjunction with their standard of care therapy.

The purpose of this study is to see whether receiving local ablative therapy (LAT) when minimal residual disease/MRD levels are rising can reduce MRD levels and control metastatic non-small cell lung cancer/NSCLC longer compared to systemic therapy.

A Phase II Adaptive Study of Local Ablative Therapy (LAT) for Patients With Metastatic Non-Small Cell Lung Cancer (NSCLC) Using Minimal Residual Disease (MRD) as an Integral Biomarker

Memorial Sloan Kettering Cancer Center supports the international committee of medical journal editors (ICMJE) and the ethical obligation of responsible sharing of data from clinical trials. The protocol summary, a statistical summary, and informed consent form will be made available on clinicaltrials.gov when required as a condition of Federal awards, other agreements supporting the research and/or as otherwise required. Requests for deidentified individual participant data can be made beginning 12 months after publication and for up to 36 months post publication. Deidentified individual participant data reported in the manuscript will be shared under the terms of a Data Use Agreement and may only be used for approved proposals. Requests may be made to: crdatashare@mskcc.org.

To determine whether Local Ablative Therapy/LAT (ablation to all sites of disease) causes a reduction in mean variant allele frequency/VAF by 6 months after LAT in patients with metastatic NSCLC who have non-responding variant allele frequency/NR-VAF (\<50% reduction in mean VAF) but no radiographic progression of disease. Mean VAF: Mean VAF will be defined by the VAF of each relevant mutation divided by the total number of mutations

PFS will be evaluated through imaging obtained Q3 months +/-2 weeks after enrollment. Progression will be evaluated by RECIST 1.1 guidelines. To determine whether LAT improves PFS in patients with metastatic NSCLC who have NR-VAF but no radiographic progression of disease compared to patients who continue systemic therapy.
