Head/Neck Neoplasm Clinical Trial
Official title:
A Phase II/III Randomized Trial of Comparison of Survival Benefit of Administration of PD1/PDL1/CTLA4 Inhibitors Via Neck Artery or Intratumor Versus Vein Infusion for Immunotherapy of HNC
This trial was designed to investigate the survival outcomes, response rates, and safety of patients with advanced Head/Neck Squamous cancer via intra-tumor or intra-artery versus vein infusion of PD1/PDL1/CTLA4 inhibitors.
Head/Neck cancer is a kind of hard-to-treat malignancy worldwide and its overall survival rate is still low. PD1/PDL1/CTLA4 inhibitors are widely used to treat various of cancers now. Delivery of antibody drugs through interventional approaches including intra-tumor or intra-artery, based on the theory of "first pass effect" of drug, can significantly increase the local drug concentration of the tumor, improve the efficacy, and reduce systemic adverse reactions. To the investigator's knowledge, no studies have been developed on the survival benefit of neck artery infusion or intra-tumor injection of immunotherapeutic agents in patients with advanced HNC. This phase II-III clinical trial was designed to compare the effects of PD1/PDL1/CTLA4 inhibitors via IA/IT and IV on the survival benefit of patients with advanced HNC, including ORR, DCR, median survival time, and safety. ;
