Adult Gliosarcoma Clinical Trial
Official title:
Targeting Recurrent Glioblastoma With Anti-CD3 x Anti-EGFR Bispecific Antibody Armed T Cells: A Phase I/II Study
This phase I/II trial studies the side effects and best dose of epidermal growth factor receptor bispecific antibody (EGFRBi)-armed autologous T cells and how well it works in treating patients with glioblastoma that have come back or does not respond to treatment. EGFRBi-armed autologous T cells coated with antibodies (proteins used by the immune system to target and kill foreign objects such as cancer cells) may have great ability to seek out, attach to, and destroy glioblastoma cells.

Inclusion Criteria: - Histologically-confirmed intracranial glioblastoma or gliosarcoma (World Health Organization [WHO] grade IV) with evidence of clinical and radiographic (computed tomography [CT] or MRI brain) tumor progression (need not be biopsy proven) - Patients who have undergone prior resection, radiation therapy, and/or chemotherapy (except bevacizumab) - Karnofsky performance score >= 70 or Eastern Cooperative Oncology Group (ECOG) performance status = 0 or 1 - Patient agrees to undergo a baseline and a follow-up 11C-alpha-methyl-L-tryptophan (AMT)-PET scan during immunotherapy (IMT) - No serious medical or psychiatric illness which prevents informed consent or intensive treatment is allowed - Non pregnant: negative serum test for pregnancy, unless male, prior hysterectomy, tubal ligation, or postmenopausal; (Note: postmenopausal is defined as age > 55 with amenorrhea for > 1 year or age < 55 years with amenorrhea for 2 years and follicle stimulating hormone (FSH) level within postmenopausal range of institutional parameters; patients requiring FSH level to determine menopausal status need not have this performed and may choose to proceed with serum pregnancy testing) - Required initial laboratory data (normal limits per treating institution; minor changes from the indicated laboratory guidelines will be allowed at the discretion of the treating team under special circumstances and reasons for the changes will be documented): - Granulocytes >= 1,000/mm^3 - Absolute lymphocyte count >= 500/mm^3 - Platelet count >= 50,000/ul - Hemoglobin >= 8 gm/dl - Blood urea nitrogen (BUN) =< 1.5 times normal - Serum creatinine < 1.8 mg/dl - Creatinine clearance >= 50 ml/mm (can be calculated utilizing the Cockcroft & Gault equation) - Bilirubin < 1.5 times upper limit of normal - Alanine aminotransferase (ALT) and aspartate aminotransferase (AST) < 5 times upper limit of normal - Alkaline phosphatase < 5 times upper limit of normal - Prothrombin time (PT) or international normalized ratio (INR) and activated partial thromboplastin time (aPTT) < 1.2 times upper limit of normal - Negative human immunodeficiency virus (HIV)-1/2 serology - Negative hepatitis B surface antigen - Negative hepatitis C serology - Left ventricular ejection fraction (LVEF) >= 45% at rest (multi gated acquisition [MUGA] or echocardiogram [ECHO]) - Each patient must be aware of the nature of their disease and must willingly consent to treatment after being informed of alternatives, potential benefits, side effects, and risks - Surgery is done prior to IMT if needed for palliation, tumor debulking, pathological documentation of tumor recurrence; the patients may continue on study therapy even if they do not have measurable disease - No other investigational agents, immunomodulating agents, or cancer chemotherapy are permitted for the duration and 12 months following the study IMT unless there is disease progression; radiotherapy is not permitted; appropriate antibiotics, blood products, antiemetics, fluids, electrolytes and general supportive care are to be used as necessary Exclusion Criteria: - Resective surgery within 2 months prior to the initial pre-treatment AMT-PET scan - Severe increased intracranial pressure, status epilepticus, or other serious complications from the brain tumor, requiring emergency or urgent intervention - Patients with a history of another malignancy within 5 years of study enrollment - Patients with extracranial metastases - Evidence of active bleeding or bleeding diathesis - Patients will be ineligible for treatment on this protocol if (prior to protocol entry): - There is a history of a recent (within one year) myocardial infarction - There is a current or prior history of angina/coronary symptoms requiring medications and/or evidence of depressed left ventricular function (LVEF < 45% by MUGA or ECHO) - There is clinical evidence of congestive heart failure requiring medical management (irrespective of MUGA or ECHO results) |

Other | Persistence of aATC in blood | Will be evaluated whether the infused cells persist in vivo using fluorescence-activated cell sorting analysis for the mouse immunoglobulin G 2 alpha (IgG2a) (OKT3 part of the EGFRBi). | Up to 1 year | No |
Primary | Incidence of toxicity according to the National Cancer Institute Common Terminology Criteria for Adverse Events version 4.0 (Phase I) | Up to 7 days after the last infusion | Yes | |
Primary | Overall survival (OS) (Phase II) | The median OS will be estimated with 95% confidence interval. Kaplan-Meier estimate of OS will be plotted. For quantitative measurements in immune evaluations, will calculate their means, standard deviations, medians, and examine the distributions of these data to ascertain whether normal theory methods are appropriate. Paired t-test or Wilcoxon signed-ranks test will be used for comparative analyses between each post-IMT time point versus pre-IMT. | From study enrollment to death due to any cause, assessed up to 2 years | No |
Secondary | Change in cytokines profiles | Mean, standard deviation, median and examine the distributions of these data will be calculated to ascertain whether normal theory methods are appropriate. Paired t-test or Wilcoxon signed-ranks test will be used for comparative analyses between each post-IMT time point versus pre-IMT. Bonferroni's adjusted p-values will be reported to control type I error rate. In addition, will assess the pattern of changes in the immune responses over time using graphical techniques such as LOWESS curves. | Baseline to up to 1 year | No |
Secondary | Changes in activated T cells | Mean, standard deviation, median and examine the distributions of these data will be calculated to ascertain whether normal theory methods are appropriate. Paired t-test or Wilcoxon signed-ranks test will be used for comparative analyses between each post-IMT time point versus pre-IMT. Bonferroni's adjusted p-values will be reported to control type I error rate. In addition, will assess the pattern of changes in the immune responses over time using graphical techniques such as LOWESS curves. | Baseline to up to 1 year | No |
Secondary | Changes in cytotoxic T-lymphocyte as measured by IFN-gamma EliSpots directed at autologous tumor or GBM cell lines | Mean, standard deviation, median and examine the distributions of these data will be calculated to ascertain whether normal theory methods are appropriate. Paired t-test or Wilcoxon signed-ranks test will be used for comparative analyses between each post-IMT time point versus pre-IMT. Bonferroni's adjusted p-values will be reported to control type I error rate. In addition, will assess the pattern of changes in the immune responses over time using graphical techniques such as LOWESS curves. | Baseline to up to 1 year | No |
Secondary | Changes induced by IMT | Mean, standard deviation, median and examine the distributions of these data will be calculated to ascertain whether normal theory methods are appropriate. Paired t-test or Wilcoxon signed-ranks test will be used for comparative analyses between each post-IMT time point versus pre-IMT. Bonferroni's adjusted p-values will be reported to control type I error rate. In addition, will assess the pattern of changes in the immune responses over time using graphical techniques such as LOWESS curves. | Baseline to up to 1 year | No |
Secondary | Human anti-mouse antibody responses | Serial serum samples will be tested and evaluated for the development of immunoglobulin G (IgG) and IgM anti-mouse antibody responses. | Up to 1 year | No |
Secondary | Peripheral blood measures | Up to 1 year | No |
