Summary

This is a single-center, open-label, multi-dose phase I clinical trial evaluating the safety, tolerability, and preliminary efficacy of ZSNeo-DC1.1, a personalized dendritic cell injection, in subjects with recurrent or progressive WHO grade III-IV gliomas post-standard treatment. The subjects are adult GBM patients who have undergone surgical resection for recurrence. After the completion of reoperation, subjects will receive autologous DC vaccine treatments as scheduled. The autologous genetic-modification-free DC cells will be loaded with multiple tumor neoantigen peptides and administered (i.h) to subjects. After 3 injections, the investigator will review subject's tolerance and compliance. The DLT observation period spans from the initial injection to 21 days after the third injection, aligning with the activation of anti-tumor immune response.

About 15 subjects will be enrolled. The study utilizes a fixed dose of 1×10\^7 cells per injection and employs two immunization schedules A or B.

The trial is conducted in two stages:

Dose Confirmation Stage:

Enrollment of six subjects with recurrent or progressive gliomas following standard treatment. Each subject receives six subcutaneous injections of ZSNeo-DC1.1. Utilization of a standard "3+3" design for fixed dose confirmation and exploration of immunization schedules A and B.

Dose Expansion Stage:

Enrollment of at least six subjects with recurrent or progressive gliomas post-standard treatment. Administration of six subcutaneous injections of ZSNeo-DC1.1 to each subject, further investigating the safety and preliminary efficacy of ZSNeo-DC1.1 injection.
