A Phase III, Randomized, Placebo-controlled, Double-blind, Multi-center, International Study of Durvalumab Following Stereotactic Body Radiation Therapy (SBRT) for the Treatment of Patients With Unresected Stage I/II, Lymph-node Negative Non-small Cell Lung Cancer 


To assess the efficacy and safety of durvalumab versus placebo following SoC SBRT in patients with unresected clinical Stage I/II lymph node-negative (T1 to T3N0M0) NSCLC.

Study Arms

  • Experimental: Durvalumab Therapy
  • Placebo Comparator: Placebo Therapy


  • Histologically or cytologically documented Stage I to II NSCLC, with clinical Stage I/II lymph node-negative (T1 to T3N0M0) disease and planned to receive definitive treatment with SBRT. Patients may be medically inoperable or are medically operable and refusing surgery or choosing to have SBRT (Stereotactic Body Radiation Therapy) as definitive therapy
  • Completion of SoC SBRT as definitive treatment prior to randomization
  • World Health Organization (WHO)/Eastern Cooperative Oncology Group (ECOG) PS of 0, 1, or 2
  • Tumor sample required
  • Adequate organ and marrow function required
  • Patients with central or peripheral lesions are eligible
  • Staging studies must be done within 8 weeks before randomization
