|Stage IV Non-Small Cell Lung Cancer||Drug: Pembrolizumab Radiation: Single Fraction Radiation Therapy||Phase 2|
This is a Phase 2 randomized two arm phase II trial of pembrolizumab alone or sequentially following focal radiation to one of the target lesions, in previously treated patients with stage IV Non-Small Cell Lung Cancer (NSCLC). The primary goal of this trial is to compare the efficacy of focal radiation (RT) to an index lesion as a way of enhancing the anti-tumor immune response to pembrolizumab to that of pembrolizumab alone. The primary efficacy endpoint is overall RECIST-defined response outside the radiation field. To accomplish this goal 66 patients will be randomized 2:1 (stratified by histology (squamous versus non-squamous) and refractory versus non-refractory disease) to radiation plus pembrolizumab or pembrolizumab only, respectively.
Primary Objective: To determine the tumor responses outside the radiation field (abscopal effect) after radiation followed by pembrolizumab in metastatic NSCLC.
- To determine the progression-free and overall survival in patients with NSCLC receiving pembrolizumab, who receive Single Fraction Radiation Therapy (SFRT)
- To determine the safety and toxicity of the combination of SFRT and pembrolizumab
- To examine potential predictive biomarkers in tumor samples and peripheral blood in patients treated with pembrolizumab and SFRT
- To determine the local control of SFRT in the radiated lesion, when SFRT is given with pembrolizumab
- To evaluate the induction of a T-cell response in patients with metastatic NSCLC treated with radiation and the effect of radiation

- Number of patients with each response as measured by RECIST 1.1 [ Time Frame: From first visit to disease progression, up to 24 months after beginning treatment ]The Best Overall Response is the best response recorded from the start of the treatment until disease progression (taking as reference for progressive disease the smallest measurements recorded since the treatment started). The anti-tumor activity will be evaluated as an efficacy endpoints based on radiographic (CT or PET/CT). RECIST 1.1 will be applied for evaluation of tumor response.
- Median time of progression free survival [ Time Frame: From first visit to disease progression, up to 24 months after beginning treatment ]Progression free survival, PFS is defined as the time from initiation of study drug post-SFRT, until the first documented, confirmed progression of disease. PFS will also be measured and report from the initiation of study drug, pre-SFRT.
- Median time of overall survival [ Time Frame: From first visit to disease progression, up to 24 months after beginning treatment ]Overall Survival, OS will be measure from the initiation of study therapy
- Number of patients with local control of disease with SFRT [ Time Frame: From first visit to disease progression, up to 24 months after beginning treatment ]Local Control with SFRT: The target lesion selected for SFRT will be followed for local control. For the purpose of the study, local control will be defined as a complete response, partial response, or stable disease within the planning target volume.
- Duration of local control of disease with SFRT [ Time Frame: From first visit to disease progression, up to 24 months after beginning treatment ]Local Control with SFRT: The target lesion selected for SFRT will be followed for local control. For the purpose of the study, local control will be defined as a complete response, partial response, or stable disease within the planning target volume. The duration of local control will be measured from the time of SBRT treatment fraction.
- Number of patients with pneumonitis [ Time Frame: From first visit to 30 days after disease progression, up to 25 months after beginning treatment ]For patients receiving SFRT to lung lesions, the development of grade 3 or greater pneumonitis that is probably or definitely attributable to either SFRT or pembrolizumab within the follow-up period will be monitored
- Changes in PD-L1 [ Time Frame: From first visit to 30 days post treatment, up to 25 months ]From first visit to disease progression, up to 24 months after beginning treatment

Newly-obtained is defined as a specimen obtained up to 6 weeks (42 days) prior to initiation of treatment on Day 1. Subjects for whom newly-obtained samples cannot be provided (e.g. inaccessible or subject safety concern) may submit an archived specimen only upon agreement from the Sponsor and primary investigator.
- Have a performance status of ≤1 ECOG Performance Scale.
