PRIMARY OBJECTIVES:~I. To determine the safety and tolerability of escalating doses of off-the-shelf CB-NK-TGF-betaR2-/NR3C1- in patients with recurrent glioblastoma (GBM), occurrence of dose limiting toxicities (DLTs) and determine the maximum tolerated dose (MTD). (Group 1) II. To evaluate the immunological phenotype and anti-tumor function of NK cells in resected tumor tissue after treatment with CB-NK-TGF-betaR2-/NR3C1- in the surgical expansion group. (Group 2)~SECONDARY OBJECTIVE:~I. To determine response as measured by Response Assessment in Neuro-Oncology (RANO), duration of clinical response, progression free survival (PFS), time to progression (TTP), and overall survival (OS).~EXPLORATORY OBJECTIVES:~I. Monitoring immune responses following CB-NK-TGF-betaR2-/NR3C1- dosing, in vivo persistence and expansion of CB-NK-TGF-betaR2-/NR3C1- during treatment, characterization of immune cell subpopulations in the peripheral blood, serum analysis of immune correlates, alloreactivity characterization, and anti-HLA antibody analysis, and CB-NK-TGF-betaR2-/NR3C1- trafficking in tumor microenvironments in the surgical expansion cohort.~II. Tumor tissue from surgical resection will be further analyzed for immune infiltrates, fibrosis, and tumor microenvironment.~OUTLINE: This is a dose-escalation study followed by a dose-expansion study. Patients are assigned to 1 of 2 groups.~GROUP 1: Patients receive CB-NK-TGF-betaR2-/NR3C1- intratumorally over 5-10 minutes weekly for up to 8 doses in the absence of disease progression or unacceptable toxicity.~GROUP 2: Patients receive CB-NK-TGF-betaR2-/NR3C1- intratumorally over 5-10 minutes on days 0, 7, and 14. Patients undergo standard of care surgical resection on day 15. Beginning 2 weeks after surgery, patients receive CB-NK-TGF-betaR2-/NR3C1- intratumorally over 5-10 minutes weekly for up to 5 doses (total of 8 doses) in the absence of disease progression or unacceptable toxicity.~After completion of study treatment, patients are followed up at 7, 30, and 90 days.
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.
