Brief Summary

To observe the efficacy and safety of adebelizumab combined with chemotherapy and sequential adebelizumab combined with radiotherapy in the treatment of newly diagnosed extensive small cell lung cancer.

Detailed Description

This study is a one-arm, multi-center and exploratory study. Eligible patients will receive the following treatment schemes: adebelizumab+carboplatin+etoposide, with one treatment cycle every three weeks. After 4-6 cycles, adebelizumab maintenance therapy combined with concurrent radiotherapy will be given, and conventional radiotherapy will be given to chest lesions (2Gy*(20-30)f), brain (3Gy*10f)/ bone (3Gy*10f)/ adrenal gland. Immunotherapy is suspended during radiotherapy for chest lesions and lymph nodes in mediastinum, and immunotherapy is given 1-2 weeks after radiotherapy. Radiotherapy for other metastatic lesions can be carried out simultaneously with immunotherapy.

Research population: patients with extensive small cell lung cancer diagnosed by histopathology or cytology, both male and female, aged 18-75 years old, who have not received systemic treatment for small cell lung cancer before. 51 patients are planned to be enrolled.

Main research end point： PFS(RECIST v1.1 standard) evaluated by researchers. Secondary end point

Key secondary study endpoints:

The incidence of adverse reactions above grade 3 in patients evaluated according to CTCAE5.0 version 5.0.

Other secondary study endpoints:

Administration regimen: adebelizumab 1200mg, IV, Q3W+ carboplatin AUC 5 d1+ etoposide 100mg/m2 D1, 2, 3; 21 days is a treatment cycle. After 4-6 cycles, patients with imaging evaluation CR/PR/SD (according to tumor RECIST1.1 standard) receive adebelizumab maintenance therapy and radiotherapy at the same time. Patients with imaging evaluation PD (according to tumor RECIST1.1 standard) can receive adebelizumab maintenance therapy combined with radiotherapy according to the clinical practice, or they can change other treatment schemes and continue to follow up.

After the induction treatment, the participants will continue to receive adebelizumab (20mg/kg, IV, Q3W) combined with concurrent radiotherapy (conventional radiotherapy SBRT chest lesions (2Gy*25f), brain (3Gy*10f)/ bone (3Gy*10f)/ suprarenal gland (3Gy*10-15f)/ liver (3YX).
