Safety and Efficacy of Recombinant L-IFN Adenovirus Injection in Relapsed/Refractory Solid Tumors Clinical Study

• Status: Recruiting
• Trial end date: 2023-12-31
• Target enrollment: 0
• Participant gender: All

Summary

This is an open-label, dose escalation study of the safety and tolerability of Recombinant L-IFN adenovirus injection（YSCH-01） when administered via intratumoral injection in patients with advanced solid tumors. The purpose of this study is to assess the safety and tolerability of Recombinant L-IFN adenovirus injectionand to determine the recommended phase 1 dose for further study. The study will also evaluate antitumor activity, objective response rate, pharmacokinetics and virus shedding of Recombinant L-IFN adenovirus injection

• Phase: Early Phase 1
• Accepts Healthy Volunteers?: No
