Brief summary
This is an open-label, single arm Phase II study designed to evaluate the efficacy and safety of thoracic radiotherapy for extensive-stage small-cell lung cancer treated with PD-1/PD-L1 plus etoposide platinum followed by PD-1/PD-L1 maintenance therapy
Detailed description
This study a single arm prospective phase II study. All the enrolled patients will be patients with ES-SCLC who did not have PD (determined as per the RECIST v1.1) after 6 cycle of platinum-based chemotherapy in combination with an anti-PD-1/L1. Then, those enrolled patients would be treated with thoracic radiotherapy concurrently with PD-1/PD-L1 maintenance therapy, and the total maintenance therapy time should at least more than 6 months.
Interventions
RADIATIONthoracic radiotherapy
Four courses of carboplatin/etoposide/anti-PD-1/PD-L1 every 3 weeks All the enrolled patients will be patients with ES-SCLC who did not have PD (determined as per the RECIST v1.1) after 6 cycle of platinum-based chemotherapy in combination with an anti-PD-1/L1. Then, thoracic radiotherapy of 45 Gy/15 fractions. PD-1/PD-L1 maintenance therapy concurrently and after thoracic radiotherapy at least more than 6 months, or until intolerable toxicity, progressive disease leading to a need for other treatment, or until the patient no longer wishes to continue treatment.
