Clinical trials

This is a single-arm, prospective, exploratory phase II clinical study. The study enrolled newly diagnosed stage T1-3N0-1M0 resectable limited-stage small cell lung cancer. Adebrelimab combined with chemotherapy for 4 cycles and apatinib mesylate for 3 cycles. Surgery was performed within 4-8 weeks after the above treatment (the operation was performed 4 weeks after apatinib was discontinued). According to the results of MDT discussion, adebrelimab combined with apatinib mesylate combined with or without radiotherapy was started 4 weeks after surgery. Preoperative prophylactic radiotherapy (PCI) is recommended for patients with preoperative stage N1. Patients with postoperative stage N1 received postoperative thoracic radiotherapy.

This study aims to verify the efficacy and safety of osimertinib in patients with EGFR-sensitive mutation non-small cell lung cancer who progressed after adjuvant targeted therapy following radical surgery. The main questions it aims to answer is: whether EGFR-TKI is effective in the re-treatment of NSCLC after postoperative adjuvant targeted therapy relapse.
