Recurrent or Metastatic Lung Cancer

This study evaluates the efficacy and safety of Vorolanib as monotherapy for advanced non-small cell lung cancer (NSCLC) patients receiving third-line or higher treatments. It is a single-center, single-arm, prospective Phase II clinical trial. Thirty-two patients who have undergone at least two lines of systemic therapy and exhibited progression or recurrence will receive 300 mg of Vorolanib daily until disease progression, intolerable toxicity, withdrawal of consent, or death. The primary endpoint is the 6-month progression-free survival (PFS) rate. Secondary endpoints include PFS, objective response rate (ORR), disease control rate (DCR), overall survival (OS), and safety. This research aims to expand the clinical applications of Vorolanib in NSCLC, providing a basis for further investigation.
