Oncolytic Virus Combined With Chemotherapy and Immune Checkpoint Inhibitors in Patients With Initially Unresectable Locally Advanced Esophageal Squamous Cell Carcinoma：An Open-label, Single-arm Phase II Study
Status: Recruiting
Location: See location...
Intervention Type: Biological
Study Type: Interventional
Study Phase: Phase 1/Phase 2
SUMMARY
This clinical trial is designed to evaluate the preliminary efficacy and safety of an oncolytic virus combined with chemotherapy and an immune checkpoint inhibitor in patients with initially unresectable, locally advanced esophageal squamous cell carcinoma (ESCC). The primary endpoints are safety, surgical conversion rate and event-free survival (EFS). Secondary endpoints include overall survival (OS), objective response rate (ORR), and quality of life (QoL). Exploratory endpoints include biomarker analyses such as single-cell sequencing.

Oncolytic Virus: Administered via intratumoral (metastatic lesions in the neck or supraclavicular lymph nodes) injection once every 3 weeks, for a total of two doses, or until disease progression, the occurrence of unacceptable toxicity, or death from any cause, whichever occurs first.Chemotherapy + Immune Checkpoint Inhibitor (ICI): Administered via intravenous infusion once every 3 weeks.
