Summary

This trial is testing the side effects and best dose of carboxylesterase-expressing allogeneic neural stem cells given with irinotecan hydrochloride for high-grade gliomas. The hope is that the genetically modified neural stem cells will make the tumor more sensitive to the irinotecan hydrochloride, which may stop the growth of the tumor cells.

Who is the study for?
This trial is for patients with recurrent high-grade brain tumors like glioblastoma or astrocytoma, who have already tried standard treatments. They must be in good enough health to understand the study and undergo surgery, with a life expectancy of at least 3 months. Participants can't join if they've had neural stem cell therapy before, are on certain drugs that affect the treatment, or have infections like HIV.
What is being tested?
The trial tests genetically modified neural stem cells combined with irinotecan hydrochloride against high-grade gliomas. The goal is to see if this combo makes the cancer more sensitive to treatment and stops tumor growth by blocking key enzymes needed by cancer cells.
What are the potential side effects?
Possible side effects include reactions related to immune system activation, such as inflammation in various organs; typical chemotherapy-related issues like nausea and fatigue; blood count changes leading to increased infection risk; and potential allergic reactions.

Experimental Treatment
Group I: Treatment (hCE1m6-NSCs and irinotecan hydrochloride)Experimental Treatment5 Interventions
Patients receive carboxylesterase-expressing allogeneic neural stem cells intracranially over 1.5-4.5 hours on days 1 and 15 (day 1 only for patients at dose level 1) and irinotecan hydrochloride IV over 90 minutes on days 3 and 17. Cycles repeat every 28 days in the absence of disease progression or unacceptable toxicity.
