An Exploratory Study of QL1706 Plus Chemotherapy in Perioperative NSCLC

This is a single-center, open-label, single-arm phase II exploratory study evaluating a perioperative regimen of iparomlimab and tuvonralimab (QL1706; a bispecific PD-1/CTLA-4 antibody) combined with platinum-based chemotherapy in patients with resectable or potentially resectable stage IIB-IIIB non-small cell lung cancer (NSCLC) without actionable driver alterations. Approximately 30 eligible participants will receive three 21-day cycles of neoadjuvant QL1706 plus chemotherapy, followed by surgical resection if feasible. After surgery, participants will be followed regularly to assess pathologic response, recurrence, survival outcomes, and safety, including immune-related adverse events. The primary efficacy endpoint is major pathologic response (MPR), defined as ≤10% residual viable tumor in the resected specimen. Secondary endpoints include event-free survival, overall survival, objective response rate, disease control rate, and R0 resection rate. Exploratory analyses will evaluate changes in the tumor immune microenvironment and peripheral immune profiles using tumor tissue and blood samples, including T-cell and B-cell receptor repertoire analyses and multi-omics profiling, with the goal of developing models to predict treatment benefit and immune-related toxicity risk.
