Brief 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.

Drug: Durvalumab
Durvalumab is an FDA-approved immunotherapy for cancer. Durvalumab is a human monoclonal antibody (mAb) of the immunoglobulin G (IgG) 1 kappa subclass that inhibits binding of PD-L1 and is being developed by AstraZeneca/MedImmune for use in the treatment of cancer.
Other Names:
  • 1428935-60-7
  • D10808

Drug: Tremelimumab
Tremelimumab is a monoclonal antibody against CTLA-4. It is an IgG 2 kappa isotype mAb directed against the cytotoxic T-lymphocyte-associated protein 4 (CTLA-4) also known as CD152 (cluster of differentiation 152). This is an immunomodulatory therapy (IMT) that is being developed by AstraZeneca for use in the treatment of cancer.
Other Names:
  • 745013-59-6
  • QEN1X95CIX

Radiation: Stereotactic Body Radiotherapy
SBRT is a highly conformal approach to the delivery of radiation therapy, maximizing radiation dose to the tumor while minimizing dose to nearby normal tissues.
Other Names:
  • SRBT
  • stereotactic ablative radiotherapy
  • SABR




Primary Outcome Measures :
  1. Safety and tolerability of SBRT followed by combined durvalumab and tremelimumab, assessed by CTCAE v4.03 [ Time Frame: Up to 3 years ]
    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.


Secondary Outcome Measures :
  1. Progression Free Survival assessed with RECIST 1.1 tumor assessments [ Time Frame: Up to 4 years ]
    Progression-free survival (PFS) will be defined as the difference (in months) between the date of study enrollment and the date of disease progression or death due to any cause. PFS will be analyzed using the Kaplan-Meier method, and the Brookmeyer-Crowley method will be used to construct the 95% confidence interval for the median PFS. PFS assessed with RECIST 1.1 tumor assessments. The effect of DCI with durvalumab and tremelimumab will be compared against historical controls for a 95% CI and p-value.

  2. Overall Survival assessed with RECIST 1.1 tumor assessments [ Time Frame: Up to 4 years ]
    Overall survival (OS) will be defined as the difference (in months) between the date of study enrollment to the date death due to any cause. OS will be analyzed using the Kaplan-Meier method, and the Brookmeyer-Crowley method will be used to construct the 95% confidence interval for the median OS. The effect of DCI with durvalumab tremelimumab will be compared against historical controls for a 95% CI and p-value.


Other Outcome Measures:
  1. Evaluate immune response [ Time Frame: Up to 4 years ]
    Determine whether immune response on biopsy sections or circulating tumor cells is increased following SBRT. The paired McNemar's test will be used to compare with subjects with an immune response between assessment time point.

  2. Evaluate PD-L1 expression [ Time Frame: Up to 4 years ]
    Determine whether PD-L1 expression on biopsy sections or circulating tumor cells is increased following SBRT. PD-L1 expression will be summarized in terms of means, standard deviation, median and range. Absolute and percentage changes in PD-L1 expression levels between the pre-SBRT versus post-SBRT assessment will be calculated and evaluated using a paired t-test.
