IT or IA Infusion of PD1/PDL1/CTLA4 Inhibitors Versus IV for Immunotherapy of Head/Neck Cancers (HNC)

Phase 2

Recruiting

• Conditions: Head/Neck Neoplasm
• Interventions: Drug: PD1/PDL1/CTLA4 inhibitors

• Registration Number: NCT03952065
• Lead Sponsor: Second Affiliated Hospital of Guangzhou Medical University

Brief Summary

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 inhibitor or their combinations.

Detailed Description

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 inhibitor or their combinations via IA/IT and IV on the survival benefit of patients with advanced HNC, including ORR, DCR, median survival time, and safety.

Arm && Interventions

Group	Intervention	Description
PD1/PDL1/CTLA4 inhibitor or their combinations infusion via peripheral vein	PD1/PDL1/CTLA4 inhibitors	Routine peripheral vein infusion of PD1/PDL1/CTLA4 inhibitor or their combinations is performed.
PD1/PDL1/CTLA4 inhibitor or their combinations infusion via neck artery	PD1/PDL1/CTLA4 inhibitors	Interventional technique is used to localize neck artery to infuse the inhibitor or their combinations directly into tumor.
PD1/PDL1/CTLA4 inhibitor or their combinations infusion via intra-tumor penetration	PD1/PDL1/CTLA4 inhibitors	Interventional technique is used to intra-tumor injection of the inhibitor or their combinations directly into tumor.

Primary Outcome Measures

Name	Time	Method
Overall survival	2 years	Overall survival (OS) will be defined as the elapsed time from the enrollment to death from any cause. For surviving patients, follow-up will be censored at the date of last contact (or last date known to be alive). Follow-up for OS will occur every 12 weeks (±1 month) until death or withdrawal of consent from the study.

Secondary Outcome Measures

Name	Time	Method
Progression-free survival	2 years	Progression-free survival (PFS) will be defined as the elapsed time from the first date of study treatment until documented disease progression (as per mRECIST) or death from any cause, whichever is earlier. For patients who remain alive without progression, follow-up time will be censored at the date of last disease assessment.
Adverse event rate	2 years	Adverse event rate will be defined as the rate of patients who developed adverse event.
