Plain-language summary
This phase I trial is to find out the best dose, possible benefits and/or side effects of engineered natural killer (NK) cells containing deleted TGF-betaR2 and NR3C1 (cord blood \[CB\]-NK-TGF-betaR2-/NR3C1-) in treating patients with glioblastoma that has come back (recurrent). CB-NK-TGF-betaR2-/NR3C1- cells are genetically changed immune cells that may help to control the disease.

Inclusion criteria
. Signed and dated informed consent.
. Male or female participants aged ≥ 12 years on the day of signing informed consent.
. Has histologically confirmed supratentorial World Health Organization grade 4 recurrent astrocytoma to include recurrent IDH WT glioblastoma or gliosarcoma and recurrent IDHmutant grade 4 astrocytoma, and recurrent gliosarcoma with any prior number of recurrences, and who have received prior radiation and temozolomide therapy. Participants will be eligible if the original histology was lower-grade glioma grade 2 or 3 and a subsequent histological diagnosis of recurrent glioblastoma or IDH-mutant grade 4 astrocytoma is made.
. Karnofsky Performance Score (KPS) of \>70 at trial entry. Lansky \>70 at trial entry for patients less than 16.
. Must be at least 12 weeks from receiving conformal radiation, unless RANO criteria for early progression are met.
Questions worth asking your doctor
Bring these to your next appointment. They're a starting point for a shared conversation — not a sign you qualify or a recommendation to enrol.
1Based on my diagnosis and history, is this trial worth exploring for me — or is there a standard treatment we should try first?
2What does this trial's phase tell us about how much is already known about its safety and benefit?
3What would taking part actually involve for me — visits, tests, time, and travel?
4What are the known and possible risks or side effects I should weigh, and how would they be monitored?
5If this trial isn't the right fit, what other options or trials would you suggest I look into?
Generated to help you prepare — always confirm anything about your own eligibility and care with the study team and your doctor.
Questions for the trial coordinator
The trial coordinator is the person who runs the study day to day. These cover the practical side — logistics, costs, and what taking part would actually mean for your life. The study team confirms whether you meet the criteria; these are questions to ask, not a sign you qualify.
1What does taking part actually involve week to week — how many visits, where, and how long does each one take?
2What costs are covered by the study, and what might I have to pay for myself, including travel, parking, or time off work?
3What happens during screening, and what happens if the study team confirms I don't meet the criteria after those tests?
4Who pays for the scans, blood work, and other tests the trial requires — the study, my insurance, or me?
5How will being in the trial affect my regular care, and will my own doctor stay informed and involved?
6Can I leave the trial at any point if I change my mind, and what would happen to my care if I do?
A starting point for the conversation — always confirm anything about your own eligibility, costs, and care with the study team and your doctor.
What they're measuring
1
Incidence of dose-limiting toxicities (DLTs) (Group 1)
. A baseline brain MRI with Advance Brain Tumor Imaging (ABTI) must be obtained no more than 30 days prior to study registration
. Patients having undergone recent surgery are eligible so long as they are at least 3 weeks from resection or at least 1 week from stereotactic biopsy and recovered from any operative or perioperative complications.
. Adequate hematological function defined by white blood cell (WBC) count ≥ 3 x 10°9/L with absolute neutrophil count (ANC) ≥ 1.5 x 10°9/L, lymphocyte count ≥ 0.5 x 10°9/L, platelet count ≥ 100 x 10°/L, and Hgb ≥ 9 g/ dL (in absence of blood transfusion).
Exclusion criteria
. Has received prior therapy with Gliadel or bevacizumab.
. Has received prior interstitial brachytherapy, implanted chemotherapy, or therapeutics delivered by local injection or convection enhanced delivery.
. Is currently participating in or has participated in a study of cancer directed investigational agent or using an investigational device within 4 weeks since last dose of agent administration or device use, or is planning to continue or start treatment with Optune® during participation in this trial.
. Has known severe hypersensitivity to monoclonal antibodies, any history of anaphylaxis, or recent, within 5 months, history of uncontrolled asthma.
. Has a known history of Human Immunodeficiency Virus (HIV) (positive HIV 1/2 antibodies); HTLV1 and/or HTLV2; active Hepatitis B (e.g., HbsAg reactive) or Hepatitis C (e.g., HCV RNA \[qualitative\] is detected). Patients with prior HBV vaccination (anti-HBs positive, HbsAg negative, anti-HBc negative) will NOT be excluded.
. Has a diagnosis of immunodeficiency or is receiving any immunosuppressive therapy within 7 days prior to study registration.
. Has had prior chemotherapy or targeted small molecule therapy within 2 weeks prior to study Day 0.
. Note: Participants with ≤ Grade 2 neuropathy are an exception to this criterion and may qualify for the study.
