A Phase I Study of Repeated Neural Stem Cell-Based Virotherapy and Standard Radiation and Chemotherapy for Newly Diagnosed High-Grade Glioma
Northwestern University
Summary
The goal of this clinical trial is to learn about the safety and feasibility of administering repeated doses of neural stem cell (NSC)-conditionally replicative adenovirus (CRAd)-survivin (S)-protomer (p)k7, in persons with newly diagnosed high grade glioma. The main questions it aims to answer are: * whether multiple doses of NSC-CRAd-S-pk7 are safe and feasible * how multiple doses of NSC-CRAd-S-pk7 influence tumor response, overall survival, time to tumor progression, and quality of life. Participants will: * undergo a biopsy to confirm high grade glioma, then receive the first dose of NSC-CRAd-S-pk7 into the brain * about 2 weeks later, undergo surgery to remove the tumor and receive the second dose of NSC-CRAd-S-pk7 into the brain * start chemoradiation about 2 weeks after surgery, then about 2 weeks later, receive the 3rd dose of NSC-CRAd-S-pk7 into the brain * four weeks later, at the end of chemoradiation, receive a fourth dose of NSC-CRAd-S-pk7 into the brain. * after radiation is finished, receive standard of care chemotherapy and tumor-treating fields. Two additional doses of NSC-CRAd-S-pk7 will be given every 4 weeks.
Description
The treatment regimen contains 3 phases: Surgical phase: Patients undergo a biopsy and upon intraoperative confirmation of high grade glioma, NSC-CRAd-S-pk7 dose #1 will be injected into the biopsy site. Patients will undergo resection of the tumor 14 (+/- 3) days later, administration of second dose of the investigational product (NSC-CRAd-S-pk7 dose #2), and implantation of the catheter system. The investigational product will then be given monthly for a total of 6 doses (see below). Radiotherapy phase: After recovery from surgery (usually within 2 weeks), standard chemoradiotherapy will…

Inclusion Criteria: * Diagnosis of a high-grade glioma (WHO grade 3 or grade 4). * Patients must have presumed high grade glioma (WHO grade 3 or 4) based on clinical and radiologic evaluation for registration. * A pathologic confirmation of high grade glioma must be made at the time of stereotactic biopsy prior to NSC-CRAd-S-pk7 injection; if this is not possible, the injection will not be performed and the subject will no longer be eligible for the study). * Tumor must be accessible for injection and must not be located in the brainstem or contained within the ventricular system. * Planning…
