简要总结
An exploratory phase II trial of immune checkpoint inhibitors (ICIs, anti-PD-1/anti-PD-L1) as second-line treatment with advanced non-small cell lung cancer (NSCLC) who had long-term response to first-line immunotherapy (with or without chemotherapy).
This study aims to evaluate efficacy and safety of ICI rechallenge in long-term responders to prior ICI. Furthermore, it seeks to identify biomarkers capable of predicting the efficacy of immunotherapy and prognosis.
详细描述
This is a multi-center study. The study plans to include a total of 27 advanced NSCLCs who had benefited from first-line immunotherapy over two years before disease progression.
Participants will receive up to 17 cycles of ICI (anti-PD-1 or anti-PD-L1) monotherapy.
Optional ICI monotherapy regimens include: Pembrolizumab 200mg every 3 weeks, or Tislelizumab 200mg every 3 weeks, or Camrelizumab 200mg every 3 weeks, or Toripalimab 240mg every 3 weeks.
The outcomes including efficacy and safety will be examined. Additionally, peripheral blood samples will be collected before treatment, and at the 6th, 12th, and 24th weeks after treatment initiation to explore biomarkers for immunotherapy. Also it is highly recommended to collect pretreatment tumor tissue from patients.

- •Subjects must be willing and able to comply with study visits, treatment plans, laboratory tests, and other study procedures;
- •Female subjects of childbearing potential and male subjects with female partners of childbearing potential must agree to use highly effective contraception during the study and for 180 days after the last dose of the study drug.
