7. Study Summary
Lay Summary | : Small cell lung cancer (SCLC), accounting for 10% of all lung cancers (Torre et al., 2015), shows poor outcomes with 7-10 months of median survival in advanced cases (Jett et al., 2013). Despite novel treatment strategies including targeted therapy and immunotherapy for non-small cell lung cancer (NSCLC) have been introduced, the treatment options for SCLC still remain limited. Many clinical trials, which tested the efficacy of molecular targeted agents for SCLC, failed to show clinical benefit compared with conventional platinum-based chemotherapy (Koinis et al., 2016). Nevertheless, recent studies demonstrated that immunotherapy using anti-CTLA-4 or anti-PD1 monoclonal antibody can be novel therapeutic strategies for SCLC (Ott et al., 2015; Reck et al., 2013; SJ et al., 2015). In recent years, many studies have shown that radiation therapy can be a useful treatment as a combining treatment with immunotherapy. The abscopal effect refers to the ability of radiation delivered radiation delivered to a local site to treat the other diseases outside radiation field (Tang et al., 2014). A recent study described that abscopal effect was observed in a malignant melanoma patient treated with CTLA4 antagonist and radiotherapy (Postow et al., 2012). Moreover, an animal study presented that blockade of PD-L1 and ionizing radiation showed synergism (Deng et al., 2014). Based on these emerging evidences, we hypothesized that local radiation therapy can enhance the effect of anti-PD-L1 monoclonal antibody through increasing T-cell effector function against tumors. Atezolizumab, which is a humanized anti-PD-L1 monoclonal antibody, act as an inhibitor the interaction between PD-L1 and PD-1, and eventually restore suppressed T-cell immunity leading elimination of cancer cells. In this study, we will investigate the combining effect of hypofractionated-sublethal dose of radiation therapy followed by anti-PD-L1 monoclonal antibody, atezolizumab, for SCLC patients who are recurrent or refractory for initial platinum-based chemotherapy. |

Arm Description This is a single arm phase II study of sequential hypofractionated radiotherapy followed by atezolizumab in patients with recurrent or refractory SCLC previously treated with platinum-based chemotherapy. A total of 35 eligible patients will be enrolled. All toxicities are graded according to the National Cancer Institute Common Toxicity Criteria Version 4.0. Radiation therapy will be delivered to the largest or most representative lesion among primary and metastatic lesions every other day since D1 of 1st cycle of atezolizumab.

INR and aPTT ≤ 1.5 x ULN This applies only to patients who are not receiving therapeutic anticoagulation; patients receiving therapeutic anticoagulation should be on a stable dose for at least 1 week prior to the first dose of atezolizumab. Creatinine clearance ≥ 30 mL/min Cockcroft-Gault, CKD EPI, or MDRD formulas may be used for creatinine clearance calculation.
