Summary

This study is an open, single-arm, single-center phase II clinical study, which aims to evaluate the efficacy and safety of adebelizumab combined with irinotecan liposome in the second-line treatment of advanced small cell lung cancer, explore biomarkers to predict the efficacy, and further select the dominant population in immunotherapy. In this study, 46 patients with extensive SCLC who had previously received immunotherapy combined with chemotherapy were enrolled. Subjects who met the enrollment conditions will be given adebelizumab combined with irinotecan liposome at the same time. After 4-6 cycles of treatment, if their condition has not progressed, they will be treated with adebelizumab until the disease progresses, toxicity can not be tolerated or other reasons specified in the scheme can be terminated. Subjects who finish the treatment will enter the follow-up period for safety follow-up and survival follow-up.

Conditions

• Small Cell Lung Cancer

Interventions

Type	Name	Description
DRUG	Adebelizumab combined with irinotecan liposome as second-line therapy	Adebellizumab: intravenous drip, 1200mg, the infusion time is controlled between 30-60 minutes, and the infusion is completed within 2 hours at most. It is administered on the first day of each cycle and repeated once every 3 weeks.Irinotecan liposome: intravenous drip, 80mg/m2, infusion time of 30 minutes, the first dose of each cycle, repeated once every 3 weeks.After 4-6 cycles of adebelizumab combined with irinotecan liposome treatment, the subjects who did not develop the disease continued to use adebelizumab (1200mg, D1, Q3W) for maintenance treatment until the disease progressed, the toxicity was intolerable, the subjects voluntarily asked to withdraw and the researchers judged that the subjects needed to withdraw from the study.
