Multiple Intracerebral Doses of Neural Stem Cell-Based Virotherapy (NSC-CRAd-S-pk7) for the Treatment of Recurrent High-Grade Gliomas
What this study is about
This phase I trial studies the safety of giving multiple intracerebral doses of NSC-CRAd-S-pk7 to treat patients with glioblastoma at first recurrence. NSC-CRAd-S-pk7 consists of neural stem cells that can target glioblastoma cells and carry a virus, which can kill cancer cells. Giving multiple doses of NSC-CRAd-S-pk7 may kill more tumor cells.

Interventions
BIOLOGICAL
Neural Stem Cells-expressing CRAd-S-pk7
Given intracerebrally
PROCEDURE
Resection
Undergo surgical resection
Primary outcome measures
Incidence of adverse events
Time frame: Up to 30 days post removal of Rickhams
Assessed using the Common Terminology Criteria for Adverse Events version 5.0.
Progression-free survival (PFS)
Time frame: From the time of surgery to the event date of progression, assessed at 6 months]
Will estimate the rate 90% confidence interval (CI) for PFS at 6 months and use Kaplan Meier methods to estimate median PFS for all study participants as well as for the cohorts of glioblastoma (GBM) participants at first recurrence who will be treated with 4 doses of NSC-CRAd-S-pk7 given once a week or every two weeks.
Who can participate
This study lists these criteria on ClinicalTrials.gov. A study coordinator reviews eligibility during screening — this page does not determine whether you qualify.
Inclusion criteria
- Patient must be age \>= 18 years
- Patient has a Karnofsky performance status of \>= 70%
- Patient has a life expectancy of \>= 3 months
- When determining the maximum tolerated number of treatment cycles (MTC): patient has a histologically confirmed diagnosis of a grade 3 or 4 glioma (eg., glioblastoma, grade 4 astrocytoma, grade 3 astrocytoma, grade 3 oligodendroglioma). (This part of the study has been completed).
- When enrolling to Treatment Schedules 4 and 4a: patient has glioblastoma at first recurrence.
- Imaging studies show evidence of recurrent, supratentorial tumor(s).
- Patient's high-grade glioma has recurred or progressed after prior treatment with brain radiation and temozolomide
- The patient must be in need of surgery for tumor resection
- Based on the neurosurgeon's judgment, there is no anticipated physical connection between the post-resection tumor cavity and the cerebral ventricles
- Absolute neutrophil count (ANC) of \>= 1000 cells/mm\^3
- Platelet count \>= 100,000 cells/mm\^3
- Total bilirubin =\< 2.0 mg/dl
- Aspartate aminotransferase (AST) (serum glutamic oxaloacetic transaminase \[SGOT\]) =\< 4 times the institutional upper limit of normal
- Serum creatinine =\< the institutional upper limit of normal
- At least 2 weeks from taking the last dose of a targeted agent
- At least 4 weeks from the last dose of bevacizumab For temozolomide, an interval of 23 days is required from the last dose administered if the patient was recently treated with adjuvant temozolomide, consisting of temozolomide daily for 5 days, repeated every 28 days.
- At least 2 weeks from taking the last dose of a targeted agent.
- At least 4 weeks from the last dose of bevacizumab.
- All significant toxicities from previous anticancer therapy must have stabilized to a new baseline or resolved.
- All participants must have the ability to understand and the willingness to sign a written informed consent.
- The effects of this treatment on a developing fetus are unknown. Therefore, female patients of childbearing potential and sexually-active male patients or who are able to impregnate their partner, must agree to use an effective method of contraception while participating in this study. Patients of childbearing potential must have a negative pregnancy test =\< 2 week prior to registration.
Exclusion criteria
- Patient has multi-focal disease.
- Patient is receiving radiation, chemotherapy, or another investigational agent.
- Patient has had prior therapy with neural stem cells.
- Patient has not recovered from any toxicity (\> grade 1) of prior therapies, except alopecia.
- Patient is unable to undergo a brain MRI.
- Patient has chronic or active viral infections of the central nervous system (CNS).
- Patient has a coagulopathy or bleeding disorder.
- Patient has an uncontrolled illness including ongoing or active infection.
- Patient has another active malignancy.
- Patient is pregnant or breastfeeding.
- A patient has a 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.

Frequently asked questions
What is a clinical trial?
A clinical trial is a research study that tests new medical treatments, drugs, devices, or procedures to determine their safety and effectiveness. Trials are carefully designed and monitored to protect participants while advancing medical knowledge.
Is it safe to participate?
Clinical trials follow strict safety guidelines and ethical standards. Trials must be reviewed and approved, and participants are closely monitored by medical professionals throughout the study. You can withdraw at any time if you choose.
Will I be compensated?
Many clinical trials offer compensation for your time, travel expenses, and inconvenience. The specific compensation varies by study and will be discussed during the screening process. All study-related medical care is typically provided at no cost to participants.
Will I receive a placebo instead of treatment?
When effective treatment exists, participants typically receive either the standard treatment plus the study intervention, or the standard treatment plus placebo. You would not be denied effective care. Placebos are primarily used when no proven treatment is available, or in addition to standard care. Your trial consent form will clearly explain what treatments you may receive.
Can I leave a trial if I change my mind?
Absolutely. Participation in clinical trials is completely voluntary. You have the right to withdraw from the study at any time, for any reason, without penalty or loss of benefits to which you are otherwise entitled.
How long does a clinical trial last?
Trial duration varies widely depending on the study design and purpose. Some trials last just a few weeks, while others may continue for months or years. The study coordinator will provide specific timeline information during your screening call.
