Carboxylesterase-Expressing Allogeneic Neural Stem Cells and Irinotecan Hydrochloride in Treating Patients With Recurrent High-Grade Gliomas

• Status: Suspended
• Trial end date: 2021-12-31
• Target enrollment: 0
• Participant gender: All

Summary

This phase I trial studies the side effects and best dose of carboxylesterase-expressing allogeneic neural stem cells when given together with irinotecan hydrochloride in treating patients with high-grade gliomas that have come back. Placing genetically modified neural stem cells into brain tumor cells may make the tumor more sensitive to irinotecan hydrochloride. Irinotecan hydrochloride may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth. Giving carboxylesterase-expressing allogeneic neural stem cells and irinotecan hydrochloride may be a better treatment for high-grade gliomas.

Criteria

Inclusion Criteria:

• Patient must be able to understand and be willing to sign a written informed consent document

• Participant must be willing to comply with study and/or follow-up procedures

• Karnofsky performance status >= 70%

• Life expectancy of >= 3 months

• Histologically-confirmed diagnosis of a grade III or IV glioma (including glioblastoma, anaplastic astrocytoma, gliosarcoma, anaplastic oligodendroglioma, or anaplastic oligoastrocytoma), or has a prior, histologically-confirmed, diagnosis of a grade II glioma and now has radiographic findings consistent with a high-grade glioma (grade III or IV)

• Imaging studies show evidence of recurrent tumor(s); if a patient is going to be enrolled to dose level two or higher, the patient must have a component of supratentorial disease (so as to enable placement of a Rickham reservoir/catheter) that is amenable to resection or biopsy

• High-grade glioma has recurred or progressed after prior treatment with brain radiation and temozolomide

• Participant must be in need of a craniotomy for tumor resection or a stereotactic brain biopsy for the purpose of diagnosis or differentiating between tumor progression versus treatment-induced effects following radiation therapy +/- chemotherapy

• Based on the neurosurgeon?s judgment, there is no anticipated physical connection between the post-resection tumor cavity and the cerebral ventricles

• Neurosurgeon finds the prospective participant is able to undergo neurosurgery

• Any number of prior therapies is permitted; from the start of study treatment, the following time periods must have elapsed: 6 weeks from nitrosourea-containing chemotherapy, 4 weeks from non-nitrosourea-containing cytotoxic chemotherapy (except 23 days from last daily dose of temozolomide taken in a 5 of 28 day regimen), and 2 weeks from last dose of a targeted agent (except 4 weeks for bevacizumab); there is no time period requirement for prior radiation therapy

• Any clinically significant toxicity from prior therapy must have improved to grade 0 or grade 1

• Absolute neutrophil count (ANC) >= 1,500 cells/ul

• Platelets > 100,000 cells/ul

• Total bilirubin =< 2.0 mg/dl

• Aspartate aminotransferase (AST) (serum glutamic oxaloacetic transaminase [SGOT]) =< 4 times institutional upper limit of normal

• Serum creatinine =< 1.5 x the institutional upper limit of normal

• Homozygous negative for the UDP glucuronosyltransferase 1 family, polypeptide A1 (UGT 1A1)*28 allele

• Absence anti-human leukocyte antigen (HLA) antibodies specific for HLA class I antigens expressed by the coagulation factor III (thromboplastin, tissue factor) (F3).cytosine deaminase (CD).carboxylesterase (CE) NSCs

• Negative serum pregnancy test (women of childbearing potential only)

• Agreement by females of childbearing potential and sexually active males to use an effective method of contraception while participating in this study; women of childbearing potential must have a negative pregnancy test < 2 weeks prior to registration

Exclusion Criteria:

• Prior therapy with neural stem cells

• Use of cytochrome P450, family 3, subfamily A, polypeptide 4 (CYP3A4) inducers including hepatic enzyme-inducing anticonvulsants (phenytoin, fosphenytoin, carbamazepine, phenobarbital, primidone, oxcarbazepine) within 2 weeks prior to start of study treatment

• Use of moderate to strong CYP3A4 inhibitors within 2 weeks prior to start of study treatment

• Use of drugs known to inhibit UGT1A1, such as atazanir, gemfibrozil, indinavir, or ketoconazole, within 2 weeks prior to start of study treatment

• Co-medication that may interfere with study results; e.g. immuno-suppressive agents other than corticosteroids, such as systemic cyclosporine and tacrolimus; consult principal investigator for questions, including necessary washout period for the specific drug

• Flucytosine within 2 weeks prior to start of study treatment

• Use of herbal medications

• Current use (or planned use during the treatment period) of other investigational agents, or biological, chemotherapy, radiation or other anti-tumor therapy

• Patient has known human immunodeficiency virus (HIV) or hepatitis C infection; baseline testing for HIV or hepatitis C is not required

• Prospective participant is unable to undergo a magnetic resonance imaging (MRI) with contrast agent

• Known chronic or active viral infections of the central nervous system (CNS)

• Clinically significant uncontrolled illness

• Active infection requiring antibiotics

• Diagnosis of Gilbert?s disease

• History of allergic reactions attributed to compounds of similar chemical or biologic composition to irinotecan

• Known sensitivity to any of the products to be administered during dosing

• Any other active malignancy

• Pregnant women and women who are lactating

• Serious medical or psychiatric illness that could, in the investigator?s opinion, potentially interfere with the safety monitoring requirements and completion of treatment according to this protocol

• Prospective participants who, in the opinion of the investigator, may not be able to comply with all study procedures (including compliance issues related to feasibility/logistics)
