Study 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.Check my eligibility
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.See study design
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.

Frequently Asked Questions

These questions and answers are submitted by anonymous patients, and have not been verified by our internal team.

Would I qualify to participate in this research program?

"Currently, 18 individuals with glioma aged between 18 and 69 are eligible to apply for this clinical trial. Candidates must fulfill the following conditions: comprehension of written informed consent documents, having a Karnofsky performance status >= 70%, willingness to adhere to study/follow-up procedures, life expectancy > 3 months, histologically confirmed diagnosis of grade II - IV glioma (including but not limited to glioblastoma and anaplastic oligoastrocytoma), imaging evidence indicating recurrence or progression after previous radiation therapy + temozolomide treatment; if enrolling at dose level two or higher there"

Answered by AI

In what conditions are Pharmacological Studies most frequently prescribed?

"Pharmacological Study is a common intervention for treating malignant neoplasms of the pancreas. Additionally, this medication may aid in managing metastasis, gastric cancer, and rhabdomyosarcoma cases."

Answered by AI

To what extent can participating in a Pharmacological Study jeopardize patient safety?

"Our enterprise has assigned Pharmacological Study a score of 1 due to the limited data available surrounding its safety and efficacy as this is an initial-phase trial."

Answered by AI

What are the intended outcomes of this experiment?

"The aim of this 28 day clinical trial is to determine the frequency of adverse reactions as evaluated by the NCI CTCAE v4.0 while also monitoring other secondary objectives, such as patient response based on MRI results, NSC immunogenicity after first and repeat exposures, and ultimately measuring NSC persistence through descriptive statistics and graphical methods."

Answered by AI

Does this experiment have any available spaces for volunteers?

"Unfortunately, according to clinicaltrials.gov this trial is no longer searching for patients. Despite that being the case, it was initially posted on March 7th 2016 and last updated on June 7th 2022. Fortunately, there are still 1,885 other studies actively recruiting right now."

Answered by AI

How many individuals are being enrolled in this experimental study?

"Unfortunately, this trial is not currently open to new participants. It was first announced on March 7th 2016 and last updated on June 7th 2022. Nonetheless, if you are seeking out other medical studies, there are 1622 trials actively searching for glioma patients and 263 Pharmacological Studies welcoming volunteers."

Answered by AI

Could you please provide an overview of any past experimentation regarding Pharmacological Study?

"At present, 263 clinical trials related to Pharmacological Study are in progress with 53 of them being in their third phase. The most numerous concentration of these studies is located in Melbourne, Victoria but there are 8629 locations across the world running research for this particular study."

Answered by AI

Is this trial open to elderly participants?

"Patients of legal age (over 18) and under 69 are eligible for inclusion in this study."
