Stereotactic Body Radiation Therapy, Durvalumab, and Tremelimumab in Treating Patients with Stage IV Non-small Cell Lung Cancer

Trial Status: Active

This phase Ib trial studies the side effects of stereotactic body radiation therapy, durvalumab, and tremelimumab and to see how well they work in treating patients with stage IV non-small cell lung cancer. Stereotactic body radiation therapy uses special equipment to position a patient and deliver radiation to tumors with high precision. This method can kill tumor cells with fewer doses over a shorter period and cause less damage to normal tissue. Immunotherapy with monoclonal antibodies, such as durvalumab and tremelimumab, may help the body’s immune system attack the cancer, and may interfere with the ability of tumor cells to grow and spread. Giving stereotactic body radiation therapy, durvalumab, and tremelimumab may work better in treating patients with non-small cell lung cancer.

I. To determine the safety and tolerability of combined durvalumab and tremelimumab in combination with stereotactic body radiation therapy (SBRT) to all sites of disease in patients with 6 or less extracranial sites of oligometastatic non-small cell lung cancer (NSCLC).


I. To evaluate the potential benefit of SBRT to all metastatic sites combined with durvalumab and tremelimumab with respect to progression free survival (PFS), and overall survival (OS).


I. To determine whether immune response and PD-L1 expression on biopsy sections or circulating tumor cell (CTC)s is increased following SBRT and whether this correlates with tumor response, PFS, and OS.

II. To further understand the effects of treatment, both tumor biopsy and peripheral blood will be obtained before and after treatment.


Patients undergo SBRT for 5 fractions over 14 days. Within 7 days, patients receive tremelimumab intravenously (IV) over 1 hour and durvalumab IV over 1 hour on day 1. Treatment with durvalumab repeats every 4 weeks in the absence of disease progression or unacceptable toxicity.

After completion of study treatment, patients are followed up at 30 days, 2, 3, 4, 6, 8, 10, and 12 months, and then every 6 months thereafter.
