ClinConnect Summary

This clinical trial is exploring a new treatment for patients with recurrent glioblastoma and related brain tumors. The researchers are testing specially engineered immune cells called natural killer (NK) cells that have been altered to potentially improve their ability to fight the cancer. The main goals of this study are to find the best dose of these modified cells and to learn about any benefits or side effects they may cause.

To participate in this trial, you must be at least 18 years old and have a confirmed diagnosis of a specific type of recurrent brain tumor (like glioblastoma) after having received prior treatments, including radiation and chemotherapy. You also need to meet certain health requirements to ensure your safety during the trial. If you join, you can expect to receive these engineered NK cells and be closely monitored for how your body responds. It’s important to know that this is an early-stage trial, which means researchers are still learning how effective this treatment might be and what side effects it may cause.

• • 2. Male or female participants aged ≥ 12 years on the day of signing informed consent.
• • 3. Has histologically confirmed supratentorial World Health Organization grade 4 recurrent astrocytoma to include recurrent glioblastoma (IDH-wildtype grade 4 astrocytoma) recurrent IDH-mutant 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.
• • 4. Karnofsky Performance Score (KPS) of \>70 at trial entry. Lansky \>70 at trial entry for patients less than 16.
• • 5. Must be at least 12 weeks from receiving conformal radiation, unless RANO criteria for early progression are met.
• • 6. A baseline brain MRI with Advance Brain Tumor Imaging (ABTI) must be obtained no more than 30 days prior to study registration
• • 7. 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. Patients with non-measurable tumor after resection will NOT be excluded; if they do not experience tumor progression while on trial, response will be labeled as "stable disease" (and not as "complete response").
• • 8. 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).
• • 9. Adequate hepatic function defined by a total bilirubin level ≤ 1.5 x ULN, an AST level ≤ 2.5 x ULN, and an ALT level ≤ 2.5 x ULN, and INR ≤ 1.5
• • 10. Adequate renal function defined creatinine ≥ 1.5 X upper limit of normal (ULN) OR creatinine clearance ≥ 60 mL/min for participant with creatinine levels \> 1.5 X institutional ULN
• • 11. Female participant of childbearing potential should have a negative serum pregnancy test within 14 days (+/-2 working days) of study registration.
• • 12. Female participants of childbearing potential should be willing to use 2 methods of birth control or be surgically sterile, or abstain from heterosexual activity for the course of the study and for 3 months after the last dose of study therapy. Participants of childbearing potential are those who have not been surgically sterilized or have not been free from menses for \> 1 year.
• • 13. Male participants should agree to use 2 methods of highly effective contraception starting with the first dose of study therapy and for 3 months after the last dose of study therapy.
• • 14. For the surgical expansion group (Group 2): there must be at least 1 cm2 of contrast-enhancing disease that is considered resectable by the neurosurgeon.
• • Exclusion Criteria
• • 1. Has received prior therapy with Gliadel or bevacizumab.
• • 2. Has received prior interstitial brachytherapy, implanted chemotherapy, or therapeutics delivered by local injection or convection enhanced delivery.
• • 3. Is currently participating in or has participated in a study of cancer directed investigational agent or using an investigational device 4 weeks since last dose of agent administration, or is planning to continue or start treatment with Optune during participation in this trial.
• • 4. Has known severe hypersensitivity to monoclonal antibodies, any history of anaphylaxis, or recent, within 5 months, history of uncontrolled asthma.
• • 5. 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.
• • 6. Has a diagnosis of immunodeficiency or is receiving any immunosuppressive therapy within 7 days prior to study registration.
• • 7. Has had prior chemotherapy or targeted small molecule therapy within 2 weeks prior to study Day 0.
• • 1. Note: Participants with ≤ Grade 2 neuropathy are an exception to this criterion and may qualify for the study.
• • 2. Note: If participant received major surgery (other than craniotomy), they must have recovered adequately from the toxicity and/or complications from the intervention prior to starting therapy.
• • 8. Has had prior radiation therapy less than 12 weeks prior to study registration, unless RANO criteria for early progression are met.
• • 9. Has had prior therapy with any antibody/drug targeting T cell co-regulatory proteins (immune checkpoints) such as anti-PD-1, anti-PD-L1, or anti-CTLA-4 antibody within the last three months prior to study registration -.
• • 10. Has a known additional malignancy that is progressing or requires active treatment.
• • Exceptions include but are not limited to basal cell carcinoma of the skin, squamous cell carcinoma of the skin, or in situ cervical cancer that has undergone potentially curative therapy. Any exceptions must be discussed with the protocol PI.
• • 11. Has known gliomatous cerebri, extracranial disease, or tumor localized primarily to the brainstem or spinal cord.

Participants with hypothyroidism stable on hormone replacement or Sjogren's syndrome will not be excluded from the study.
