This single-arm, open-label, Phase II study assesses first-line QL1706 (iparomlimab and tuvonralimab, an anti-PD-1/CTLA-4 bispecific antibody) combined with platinum-based chemotherapy to treat patients with treatment-naïve, locally advanced or metastatic, SMARCA4-deficient non-small cell lung cancer (NSCLC).
The main questions it aims to answer are:Evaluate the efficacy and safety of this combination regimen in this specific patient population. Explore correlations between tumor molecular characteristics, the immune microenvironment, and treatment efficacy or toxicity.
Participants must:
Have histologically or cytologically confirmed, treatment-naïve, locally advanced or metastatic non-small cell lung cancer (NSCLC) with SMARCA4 deficiency. Be willing to provide archived or fresh tumor tissue samples. If unavailable, enrollment may proceed per investigator assessment. Have at least one measurable lesion per RECIST v1.1.
