Recurrent Gliosarcoma Clinical Trial
Official title:
A Phase I Clinical Trial With a Window-of-Opportunity Component of Engineered NK Cells Containing Deleted TGF-ßR2 and NR3C1 in Recurrent Glioblastoma
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.

Note: Subjects with = Grade 2 neuropathy are an exception to this criterion and may qualify for the study. b. Note: If subject received major surgery (other than craniotomy), they must have recovered adequately from the toxicity and/or complications from the intervention prior to starting therapy. - Has had prior radiation therapy less than 12 weeks prior to study registration, unless RANO criteria for early progression are met. - 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 - 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. - Has known gliomatous cerebri, extracranial disease, or tumor localized primarily to the brainstem or spinal cord. - Midline shift greater than 0.5 cm or pending herniation - Tumors larger than 5 cm at greatest diameter - Has an active autoimmune disease requiring systemic treatment within the past 3 months or a documented history of clinically severe autoimmune disease, or a syndrome that requires systemic steroids or immunosuppressive agents. Subjects with vitiligo or resolved childhood asthma/atopy would be an exception to this rule. Subjects that require intermittent use of bronchodilators or local steroid injections would not be excluded from the study. Subjects with hypothyroidism stable on hormone replacement or Sjogren's syndrome will not be excluded from the study. - Has evidence of interstitial lung disease or active, non-infectious pneumonitis. - Has an active infection requiring systemic therapy or that in the opinion of the PI may interfere with the subject's participation, assessment of experimental treatment toxicity or increase the subject's risk of side effects. - Has a history or current evidence of any condition, therapy, or laboratory abnormality that might confound the results of the trial, interfere with the subject's participation for the full duration of the trial, or is not in the best interest of the subject to participate in the opinion of the treating investigator. - Has known psychiatric or substance abuse disorders that would interfere with cooperation with the requirements of the trial. - Is pregnant, breastfeeding, or expecting to conceive or father children within the projected duration of the trial, starting with the screening visit and through 3 months after last dose of the study treatment. - Has received a live vaccine within 30 days prior to the first dose of trial treatment. - Has a contraindication for undergoing MRIs. - Has evidence of bleeding diathesis or coagulopathy. - Is on full dose anticoagulants or antiplatelet therapy - Has significant hemorrhage on baseline MRI defined as >1 cm diameter of acute blood. - Has received any organ transplantation, including allogeneic stem-cell transplantation, but with the exception of transplants that do not require immunosuppression (e.g., corneal transplant, hair transplant). - Has multifocal disease. Subject has multifocal GBM, defined as discrete sites of contrast enhancing disease without contiguous T2/FLAIR abnormality that require distinct radiotherapy ports. Satellite lesions that are associated with a contiguous area of T2/FLAIR abnormality as the main lesion(s) and that are encompassed within the same radiotherapy port as the main lesion(s) are permitted. |

|---|---|---|---|---|
| Primary | Incidence of dose-limiting toxicities (DLTs) (Group 1) | 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. | Up to 28 days | |
| Secondary | Overall survival (OS) | 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. | From definitive histological diagnosis until the time of death, assessed up to 90 days post-treatment | |
| Secondary | Objective response rate (ORR) | 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. | Up to 90 days post-treatment | |
| Secondary | Duration of response (DOR) | From the time of initial response until documented tumor progression per RANO criteria, assessed up to 90 days | ||
| Secondary | Time to progression (TTP) | 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. | From the date of start of treatment until the tumor progression as defined by RANO, assessed up to 90 days post-treatment | |
| Secondary | Progression-free survival (PFS) | 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. | 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 |
