Cancer Stem Cell High-Throughput Drug Screening Study

Study Purpose

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.

Recruitment Criteria

Accepts Healthy Volunteers

Healthy volunteers are participants who do not have a disease or condition, or related conditions or symptoms

No
Study Type

An interventional clinical study is where participants are assigned to receive one or more interventions (or no intervention) so that researchers can evaluate the effects of the interventions on biomedical or health-related outcomes.


An observational clinical study is where participants identified as belonging to study groups are assessed for biomedical or health outcomes.


Searching Both is inclusive of interventional and observational studies.

  • - Platelet count > 100,000/mm3.

  • - 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.
  • - Active infection, (including known Acquired Immunodeficiency Syndrome (AIDS) and Hepatitis C) within 3 days prior to the study enrollment.
  • - Diseases or conditions that obscure toxicity or dangerously alter drug metabolism.
  • - Serious intercurrent medical illness (e.g., symptomatic congestive heart failure) - Any serious medical condition, laboratory abnormality, or psychiatric illness that would prevent the subject from providing informed consent unless they have a legal authorized representative that can consent on their behalf.
  • - 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.
  • - History of myocardial infarction or unstable angina within 6 months.
  • - History of stroke or transient ischemic attack within 6 months.
  • - Significant vascular disease (e.g., aortic aneurysm, requiring surgical repair or recent peripheral arterial thrombosis) within 6 months.
  • - History of hemoptysis (≥ 1/2 teaspoon of bright red blood per episode) within 1 month.
  • - Evidence of bleeding diathesis or significant coagulopathy (in the absence of therapeutic anticoagulation).
  • - Grade 2 or higher peripheral neuropathy per NCI CTCAE version 4.
  • - History of abdominal fistula or gastrointestinal (GI) perforation within 6 months.
  • - Serious, non-healing wound, active ulcer, or untreated bone fracture.
  • - Allergies to reagents used in this study.
  • - Women of child bearing age not willing to use a reliable form of contraception.
  • - Pregnancy (positive pregnancy test) or lactation.
  • - 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.
Patients may enroll/consent in the Phase 0 portion of this study for tissue collection and HTS while being treated with standard of care or clinical trial for newly diagnosed GBM prior to recurrence. Inability or unwilling to comply with protocol or study procedures.

Trial Details

Trial ID:

This trial id was obtained from ClinicalTrials.gov, a service of the U.S. National Institutes of Health, providing information on publicly and privately supported clinical studies of human participants with locations in all 50 States and in 196 countries.

NCT02654964
Phase

Phase 1: Studies that emphasize safety and how the drug is metabolized and excreted in humans.

Phase 2: Studies that gather preliminary data on effectiveness (whether the drug works in people who have a certain disease or condition) and additional safety data.

Phase 3: Studies that gather more information about safety and effectiveness by studying different populations and different dosages and by using the drug in combination with other drugs.

Phase 4: Studies occurring after FDA has approved a drug for marketing, efficacy, or optimal use.

Additional Details

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.

Arms & Interventions

Arms

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

Interventions

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
