Summary

Immunotherapy combined with chemotherapy has emerged as the standard of care for patients with extensive-stage small cell lung cancer (ES-SCLC). The incorporation of thoracic radiotherapy can enhance treatment efficacy. Currently, the main types of research investigating immunotherapy combined with thoracic radiotherapy for untreated ES-SCLC are concurrent radiotherapy and sequential radiotherapy. The aim of this study is to evaluate the efficacy of adebelizumab in combination with chemotherapy, when administered concurrently with radiotherapy versus sequentially with radiotherapy, as a first-line treatment for ES-SCLC.

First-line Immunotherapy Combined with Chemoradiotherapy for ES-SCLC

Cohort 1: Induction Phase: Patients will receive three cycles of atezolizumab in combination with carboplatin/cisplatin plus etoposide. Concurrent Radiotherapy Phase: the fourth cycle will incorporate concurrent radiotherapy along with atezolizumab and chemotherapy. Maintenance Phase: Atezolizumab monotherapy will be administered until disease progression or intolerance by the patient, with atezolizumab being administered for a maximum duration of 2 years. Cohort 2: Induction Phase: Patients will receive three cycles of atezolizumab in combination with carboplatin/cisplatin plus etoposide. Sequential Radiotherapy Phase: the fourth cycle will receive sequential radiotherapy in combination with atezolizumab.Final，Atezolizumab monotherapy will be continued until disease progression.
