Brief Summary
This Phase II clinical trial (investigates the efficacy of combining gemcitabine, a chemotherapy agent, with ivonescimab, a bispecific PD-1/VEGF antibody, in patients with advanced non-small cell lung...
Detailed Description
Lung cancer is the most frequently diagnosed cancer worldwide, with approximately 2.5 million new cases and 1.8 million deaths annually. Most cases are diagnosed at an advanced stage, necessitating sy...

A negative serum or urine pregnancy test before starting trial treatment is required for all women of childbearing potential.

- Major blood vessel tumor invasion.
- Minor local procedures (excluding central venous catheterization and port implantation) within 3 days prior to study treatment initiation.
- Unstable angina, myocardial infarction, congestive heart failure (NYHA classification Grade ≥2;27) or vascular disease (e.g., aortic aneurysm at risk of rupture) that required hospitalization within 12 months prior to study treatment initiation, or other cardiac impairment that may affect the safety evaluation of the study drug (e.g., poorly controlled arrhythmias, myocardial ischemia).
- History of esophageal gastric varices, severe ulcers, wounds that do not heal, abdominal fistula, intra-abdominal abscesses, or acute gastrointestinal bleeding within 6 months prior to study treatment initiation.
- History of arterial thromboembolic event, venous thromboembolic event of Grade ≥3 as specified in NCI CTCAE v5.0, transient ischemic attack, cerebrovascular accident, hypertensive crisis, or hypertensive encephalopathy within 6 months prior to study treatment initiation.
- Acute exacerbation of chronic obstructive pulmonary disease within 4 weeks prior to study treatment initiation.
- History of perforation of the gastrointestinal tract and/or fistula, history of gastrointestinal obstruction (including incomplete intestinal obstruction requiring parenteral nutrition), extensive bowel resection (partial colectomy or extensive small bowel resection) within 6 months prior to study treatment initiation.
- Any concomitant drugs contraindicated for use with the trial drugs according to the approved product information or to the Investigator's Brochure (IB).
- Known or suspected hypersensitivity to gemcitabine or ivonescimab or to any component of the trial drugs.
- History of bleeding tendencies or coagulopathy and/or clinically significant bleeding symptoms or risk within 4 weeks prior to registration, including but not limited to:
