Chemotherapy and Immunotherapy in Extensive-Stage Small-Cell Lung Cancer With Thoracic Radiotherapy

"Participants will receive thoracic radiotherapy to a dose of 30 Gray (Gy) in 10 fractions (3 Gy per day) concurrently with cycle 3 or 4 of chemo-immunotherapy (Group 1).~Participants who are unsuitable for concurrent radiotherapy may receive consolidation radiotherapy. Consolidation thoracic radiotherapy will be administered to a dose of 30 Gy in 10 fractions, following 4 cycles of chemo-immunotherapy (Group 2).~Treatment fractions will be delivered daily, where treatment should be completed within 15 days (9-10 fractions a fortnight)."

"The chemotherapy in this study is a standard treatment for extensive-stage small-cell lung cancer (EC-SCLC). The combination of chemotherapy (etoposide + carboplatin or etoposide + cisplatin) which the participant will receive is dependent on what is standard at the treatment centre.~Chemotherapy will be administered via an intravenous infusion every 3 weeks (21 days) for 4 cycles."

"The immunotherapy in this study is a standard treatment for ES-SCLC.~Participants will receive a dose of 1500 mg of Durvalumab via an intravenous infusion every 3 weeks (21 days) for 4 cycles, concurrently with chemotherapy.~A 1500 mg maintenance dose of Durvalumab will administered every 4 weeks after completion of chemotherapy (monotherapy)."
