Engineered NK Cells Containing Deleted TGF-BetaR2 and NR3C1 for the Treatment of Recurrent Glioblastoma
Study Details
Study Description
Brief 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.

Detailed Description
PRIMARY OBJECTIVES:
- 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
SECONDARY OBJECTIVE:
- 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:
-
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.
-
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.

Outcome Measures
Primary Outcome Measures
- Incidence of dose-limiting toxicities (DLTs) (Group 1) [Up to 28 days]
Will determine maximum tolerated dose and safety of escalating doses of cord blood (CB)-(NK) cells patients with recurrent glioblastoma. A DLT is defined as any grade >= 3 adverse event assessed as related to CB-NK cells by the investigator (that is, grade >= 3 adverse drug reaction; grading according to the National Cancer Institute-Common Terminology Criteria for Adverse Events version 4.03.
Secondary Outcome Measures
- Overall survival (OS) [From definitive histological diagnosis until the time of death, assessed up to 90 days post-treatment]
OS will be estimated using the Kaplan-Meier method and the comparison between or among patients' characteristics groups will be evaluated by log-rank test. Cox regression models will be applied to assess the effect of covariates of interest on OS.
- Objective response rate (ORR) [Up to 90 days post-treatment]
ORR will be defined as the proportion of patients with tumor size reduction (partial response and complete response, per Response Assessment in Neuro-Oncology [RANO] criteria). Will be calculated as the ratio of number of patients with response over number of patients treated, and 95% confidence interval of ORR will be estimated.
- Duration of response (DOR) [From the time of initial response until documented tumor progression per RANO criteria, assessed up to 90 days]
- Time to progression (TTP) [From the date of start of treatment until the tumor progression as defined by RANO, assessed up to 90 days post-treatment]
TTP will be estimated using the Kaplan-Meier method and the comparison between or among patients' characteristics groups will be evaluated by log-rank test. Cox regression models will be applied to assess the effect of covariates of interest on TTP.
- Progression-free survival (PFS) [From the start of treatment until the time of first disease progression or relapse (as defined by RANO criteria), or death due to disease, assessed up to 6 months post-treatment]
PFS will be estimated using the Kaplan-Meier method and the comparison between or among patients' characteristics groups will be evaluated by log-rank test. Cox regression models will be applied to assess the effect of covariates of interest on PFS. The point estimate of median PFS and 6-month progression-free survival (PFS6) will be estimated.
