Sequential Hypofractionated Radiotherapy Followed by Anti-PD-L1 Atezolizumab for SCLC

UnknownPhase 2

Sponsor: National Cancer Center, Korea

Conditions: Small Cell Lung Cancer Recurrent

Interventions: Atezolizumab

Countries: South Korea

The investigators hypothesized that local radiation therapy can enhance the effect of anti-PD-L1 monoclonal antibody through priming T-cell effector function against cancer cells. Described as above, The investigators concluded that modest dose of radiation to local site prior to immunotherapy is the best to enhance T-cell-mediated immunity. Accordingly, The investigators 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

Eligibility criteria

Inclusion Criteria:

1. Male or female patient aged 18 years or older
2. Histologically confirmed SCLC and available tumor tissues for PD-L1 staining
3. Progression during or after platinum-based chemotherapy.
4. At least one target tumor lesion that has not been irradiated within the past three months and that can accurately be measured in at least one dimension with longest diameter
5. Life expectancy of at least three months
6. Performance status of 0, 1, 2 on the ECOG criteria
7. Adequate hematologic and end-organ function, Patients may be transfused or receive erythropoietic treatment to meet this criterion.
8. Patient has given written informed consent which must be consistent with the International Conference on Harmonization - Good Clinical Practice (ICH-GCP) and local legislation

Exclusion Criteria:

1. Previous therapy with anti-PD-1 or -PD-L1 inhibitors
2. Persistence of clinically relevant therapy related toxicities from previous chemotherapy and/or radiotherapy
3. Chemotherapy, treatment with tyrosine kinase inhibitors, or radiotherapy (except for brain and extremities) within the past 3 weeks prior to treatment with the trial drug i.e., the minimum time elapsed since the last anticancer therapy and the first radiotherapy must be 3 weeks
4. Treatment with other investigational drugs or treatment in another clinical trial within the past three weeks before start of therapy or concomitantly with this trial
5. Concomitant yellow fever vaccination
6. Active or untreated CNS metastases as determined by CT or MRI evaluation during screening and prior radiographic assessments
7. Spinal cord compression not definitively treated with surgery and/or radiation or previously diagnosed and treated spinal cord compression without evidence that disease has been clinically stable for 2 weeks prior to randomization
8. Leptomeningeal disease
9. Uncontrolled pleural effusion, pericardial effusion, or ascites requiring recurrent drainage procedures
10. Uncontrolled tumor-related pain
11. Uncontrolled hypercalcemia or symptomatic hypercalcemia requiring continued use of bisphosphonate therapy or denosumab
12. Significant cardiovascular diseases (i.e., hypertension not controlled by medical therapy, unstable angina, history of myocardial infarction within the past 12 months, congestive heart failure \> NYHA II, serious cardiac arrhythmia, pericardial effusion)
13. Proteinuria CTCAE grade 2 or greater
14. Significant weight loss (\> 10 %) within the past 6 weeks prior to treatment in the present trial
15. Current peripheral neuropathy ≥ CTCAE(version4.0) Grade 2 except due to trauma
16. Major injuries and/or surgery with incomplete wound healing within the past ten days prior to enrollment
17. Serious infections requiring systemic antibiotic (e.g. antiviral, antimicrobial, antifungal) therapy
18. Active hepatitis C and/or B infection
19. Known human immunodeficiency virus (HIV) seropositivity
20. Serious illness or concomitant non-oncological disease such as neurologic-,psychiatric-, infectious disease or active ulcers (gastro-intestinal tract, skin) or laboratory abnormality that may increase the risk associated with study participation or study drug administration and in the judgment of the investigator would make the patient inappropriate for entry into the study
21. Patients who are sexually active and unwilling to use a medically acceptable method of contraception (e.g. such as implants, injectables, combined oral contraceptives, some intrauterine devices or vasectomized partner for participating females, condoms for participating males) during the trial and for at least 5 months after end of active therapy
22. Pregnancy or breast feeding
23. Psychological, familial, sociological or geographical factors potentially hampering compliance with the study protocol and follow-up schedule
24. Patients unable to comply with the protocol
25. Active alcohol or drug abuse
