Brief Summary:
A study to determine the safety of CSC/ HTS-based combination drug therapy in subjects who have GBM that has recurred or progressed following prior radiation therapy and TMZ.

Condition or disease Intervention/treatment Phase
Glioblastoma Multiforme Drug: Combination Drug Therapy Phase 1

Detailed Description:
This protocol describes a prospective single-center Phase 0/1 open-label study to evaluate the safety and efficacy of a high-throughput drug sensitivity assay to predict targeted therapies for patients who have GBM that has recurred or progressed following prior radiation therapy and TMZ. The underlying hypothesis is that treatment of patients with up to 3 lead candidates identified from individualized CSC/ HTS assays will safely (1) delay disease progression, and (2) increase survival. There is an abundance of literature strongly supporting the importance of a regimen for targeting CSCs and preventing tumor recurrence, as an additional strategy to improve the overall prognosis of cancer patients.

Arm Intervention/treatment
Experimental: Treatment Arm

A Drug Combination Treatment will be determined through High Throughput Screening. The classes of drugs this combination therapy will be comprised from are:

Antineoplastic Anti-infective Antiemetic Antihyperlipidemic Anti-inflammatory Antihistamine Antihypertensive Antidepressant Cardiotonic Alcohol antagonist Diuretic Antipsychotic NMDA receptor antagonist Antidiabetic Immunosuppressant Anticonvulsant Antimethemoglobinemic Sclerosing agent

Drug: Combination Drug Therapy

Up to 3 of 73 possible interventions from the drug classes listed below will be selected based on their potency against CSCs, potential for synergy without cross-reactive toxicities, drug safety profiles, pharmacokinetics, and drug-drug interactions. Those patients that have GBM that has recurred (as defined by RANO (45)), and for whom HTS was successfully completed, will be eligible to continue to the treatment component of the study to receive the drug cocktail comprised from the following drug classes:

Antineoplastic Anti-infective Antiemetic Antihyperlipidemic Anti-inflammatory Antihistamine Antihypertensive Antidepressant Cardiotonic Alcohol antagonist Diuretic Antipsychotic NMDA receptor antagonist Antidiabetic Immunosuppressant Anticonvulsant Antimethemoglobinemic Sclerosing agent





Primary Outcome Measures :
  1. Tumor size [ Time Frame: 1 year ]
  2. Progression free survival [ Time Frame: 1 year ]
  3. Overall response rate [ Time Frame: 1 year ]
  4. Overall survival [ Time Frame: 1 year ]

Ages Eligible for Study:   18 Years and older   (Adult, Older Adult)
Sexes Eligible for Study:   All
Accepts Healthy Volunteers:   No
Criteria

Inclusion Criteria:

Determined at pre-screening:

  • A histological diagnosis of GBM [WHO grade IV].
  • Subjects ≥18 years of age
  • Signed informed consent for tumor collection prior to initiation of any study-specific procedure. The patient or the patient's legal authorized representative must be able to provide written informed consent (ICF) and understand the potential risks and benefits from study enrollment and treatment
  • Patients must have a life expectancy of >12 weeks

Determined at or around surgery, and prior to performing HTS:

  • Patients must have a surgically accessible tumor with the intent for a gross or near total resection of the tumor mass (GBM, WHO grade IV)
  • Collection of sufficient tumor material for processing CSCs

Determined at or around tumor recurrence, and after completion of HTS:

• Disease progression following radiation and TMZ therapy (as defined by RANO criteria (45); Appendix 3). Unlimited relapses are allowed, provided the functional status and other eligibility criteria for enrollment are met

Determined at baseline:

  • Signed informed consent for CSC/HTS based therapy prior to initiation of any study-specific procedure or treatment. The patient or the patient's legal authorized representative must be able to provide written informed consent (ICF) and understand the potential risks and benefits from study enrollment and treatment
  • Patients must have a KPS rating of ≥70 (see Appendix 4: Karnofsky Performance Scale)
  • Patients must have recovered from the toxic effects of prior therapy to < Grade 2 toxicity per NCI CTCAE version 4 (Appendix 6) prior to Day 1 of Cycle 1. The minimum duration required between prior therapy and initiation of study drug treatment is as follows:

    • At least 12 weeks from completion of radiation therapy except if there is unequivocal evidence for tumor recurrence (such as histological confirmation) in which case at least 4 weeks from completion of radiation will suffice
    • 4 weeks from prior cytotoxic chemotherapy
    • 4 weeks from prior experimental drug
    • 6 weeks from nitrosoureas
    • 3 weeks from procarbazine
    • 1 week for non-cytotoxic agents.
  • Subjects must have adequate renal, hepatic and bone marrow function based on screening laboratory assessments. Baseline hematologic studies and chemistry and coagulation profiles must meet the following criteria:
  • Hemoglobin (Hgb)> 8 g/dL
  • Absolute Neutrophil Count (ANC) > 1,000/mm3
  • Platelet count > 100,000/mm3
  • Creatinine < 2 mg/dL
  • Alkaline Phosphatase (ALP), Aspartate Aminotransferase (AST) and Alanine Aminotransferase (ALT) < 3x upper limit of normal (ULN)
  • Patients of childbearing potential must agree to use an adequate method of contraception for the duration of the study, and for 90 days following discontinuation of study drugs
  • Females of childbearing potential must have a negative pregnancy test
  • Patients must be negative for HIV, Hepatitis B and C
  • Patients are cooperative and able to complete all the assessment procedures.

Exclusion Criteria:

  • Any condition, including the presence of clinically significant laboratory abnormalities, which places the subject at unacceptable risk if they were to participate in the study or confounds the ability to interpret data from the study

  • Diseases or conditions that obscure toxicity or dangerously alter drug metabolism
  • Serious intercurrent medical illness (e.g., symptomatic congestive heart failure)

  • Inadequately controlled hypertension (defined as systolic blood pressure >140 mmHg and/or diastolic blood pressure >90 mmHg)
  • Prior history of hypertensive crisis or hypertensive encephalopathy
  • New York Heart Association (NYHA) Grade II or greater congestive heart failure

  • Patient is positive for HIV, Hepatitis B or C
  • Concurrent use of enzyme-inducing anti-epileptic drugs (EIAEDs) Patients must discontinue an EIAED at least two weeks prior to starting study drug
  • Concurrent use of herbal medications
  • Patient is simultaneously participating in another clinical trial during the Phase 1 (treatment phase) of this study.
