Study Summary

This is a phase Ib study to evaluate safety and tolerability of dual checkpoint inhibition (DCI) of durvalumab (anti-PD-L1) and tremelimumab (anti-CTLA-4) with SBRT in the treatment of oligometastatic NSCLC. This study will examine the sequential delivery of SBRT to all disease sites followed by combination of durvalumab and tremelimumab for patients for whom the goal is ablating all known sites of disease. The investigators anticipate that for many participants this will be the first line-therapy. Participants who have received prior-platinum-based chemotherapy and/or any line of prior chemotherapy are eligible. Prior immunotherapy treatment is not allowed.

Primary Outcome

Toxicities will be summarized by type and severity in tabular format. Toxicity rates (grade 2, grade 3, grade 4, grade ≥ 2, grade ≥ 3, etc.) will be calculated and reported along the corresponding 95% confidence intervals. The 95% confidence intervals will be constructed using the Wilson score method.
