Brief Summary

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 patien...

Detailed Description

SMARCA4-deficient non-small cell lung cancer (NSCLC) represents a highly aggressive molecular subtype, accounting for approximately 5-10% of all NSCLC cases. The majority of patients (over 80%) presen...

Eligibility Criteria

Inclusion

  • Participants must meet all of the following criteria to be eligible for the study:
  • Voluntary participation and provision of signed written informed consent.
  • Age ≥ 18 years.
  • Life expectancy ≥ 3 months.
  • Histologically or cytologically confirmed diagnosis of Stage IIIB-IV lung cancer that is not amenable to curative surgery or radiotherapy.
  • Tumor demonstrates loss of BRG1 protein (encoded by the SMARCA4 gene) as confirmed by immunohistochemistry (IHC).
  • No prior systemic anti-cancer therapy for advanced disease.
  • Eastern Cooperative Oncology Group (ECOG) performance status of 0 or 1.
  • Willingness to provide archived or fresh tumor tissue samples from primary or metastatic lesions. If unavailable, enrollment may be permitted following investigator assessment.
  • At least one measurable lesion as defined by RECIST v1.1.
  • Adequate organ function within the screening period, as evidenced by:
  • 1 Absolute neutrophil count (ANC) ≥ 1.5 × 10\^9/L 10.2 Platelet count ≥ 100 × 10\^9/L 10.3 Hemoglobin ≥ 90 g/L (without transfusion within 14 days) 10.4 Serum creatinine ≤ 1 × ULN OR Creatinine clearance \> 50 mL/min (calculated by Cockcroft-Gault formula) 10.5 AST and ALT ≤ 2.5 × ULN (≤ 5 × ULN for patients with liver metastases) 10.6 Total bilirubin ≤ 1.5 × ULN (except for participants with Gilbert's syndrome) 10.7 TSH, FT3, and FT4 within normal limits (±10%)

Exclusion

  • Participants meeting any of the following criteria will be excluded from the study:
  • Pathological diagnosis containing a small cell component.
  • Symptomatic brain metastases.
  • Leptomeningeal metastases.
  • Recurrence within 6 months after completing prior adjuvant therapy (if applicable).
  • Active, known, or suspected autoimmune disease (with specific exceptions, e.g., vitiligo, type I diabetes, hypothyroidism managed with hormone replacement only).
  • Active tuberculosis (TB) infection or history of active TB within the past year.
  • Comorbidities requiring immunosuppressive medications, including systemic corticosteroids at immunosuppressive doses.
  • Pregnancy or lactation in female participants.
  • Symptomatic interstitial lung disease that could interfere with the detection or management of suspected drug-related pulmonary toxicity.
  • Known HIV infection, active Hepatitis B (HBsAg positive with HBV-DNA \> 10\^3 copies/mL), or active Hepatitis C (HCV antibody positive with detectable HCV-RNA).
  • Significant history of neurological or psychiatric disorders.
  • Treatment with any investigational drug within 4 weeks prior to the first dose of study treatment.
  • Use of Chinese herbal medicines with anti-tumor activity within 2 weeks prior to study treatment initiation.
  • History of another active malignancy within the past 2 years (with specific exceptions for certain early-stage cancers).
  • Significant cardiovascular or cerebrovascular disease history.
  • Uncontrolled thrombotic events within 6 months prior to screening.
  • Administration of a live vaccine within 28 days prior to the first study dose.
  • Major surgery or significant trauma within 4 weeks prior to the first study dose.
  • Conditions that may impair oral drug absorption.
  • Uncontrolled active infection requiring systemic therapy.
  • Known hypersensitivity to any of the study drug components.
  • Any other condition that, in the investigator's judgment, would make the participant unsuitable for participation in the study.
