Recurrent High-Grade Gliomas

SRN-101 is designed to destroys tumor cells while simultaneously activating the immune system to fight cancer. This is a first in human, single arm study to evaluate SRN-101 for the treatment of adults with recurrent high-grade glioma (rHGG) who are eligible for resection.

This is an investigator-initiated, Phase I clinical trial. It aims to evaluate the safety, tolerability, dosimetry, and preliminary anti-tumor activity of a novel radiopharmaceutical, \[177Lu\]Lu-DOTA-EB-RGD2, in patients with recurrent high-grade gliomas. Participants will receive the drug either via intravenous infusion or directly into the tumor cavity through a pre-implanted Ommaya reservoir (a subcutaneously placed device that allows direct access to the tumor cavity). The study employs a "3+3" dose-escalation design to determine the maximum tolerated dose (MTD). Adverse events, biodistribution, and tumor response (by MRI) will be assessed. Approximately 24 patients will be enrolled across two major Chinese medical centers: Beijing Tiantan Hospital and Peking Union Medical College Hospital.

This is a draft, ClinicalTrials.gov-style example record for a first-in-human Phase 1 study evaluating locoregional administration of dual-targeting chimeric antigen receptor natural killer (CAR-NK) cells in adults with recurrent or progressive glioblastoma (GBM) or other high-grade glioma (HGG). Participants will undergo tumor antigen profiling for IL13Rα2, EGFR/EGFRvIII, and B7-H3 (CD276). Based on this assessment, each participant will receive the most suitable dual-target CAR construct to reduce antigen-escape risk.
