Disulfiram and Copper Gluconate With Temozolomide in Unmethylated Glioblastoma Multiforme

The safety and scientific validity of this study is the responsibility of the study sponsor and investigators. Listing a study does not mean it has been evaluated by the U.S. Federal Government. Read our disclaimer for details. Identifier: NCT03363659

Brief Summary:
One of Disulfiram antitumor effects suggested in preclinical studies is MGMT (methyl-guanine-methyl-transferase) inhibition. Disulfiram MGMT inhibitory effect is enhanced by addition of Copper. This study evaluates the impact of DSF + Cu combination when added to standard Temozolomide in the treatment of unmethylated GBM patients.

Condition or disease Intervention/treatment Phase
Glioblastoma Glioblastoma Multiforme Drug: Disulfiram Dietary Supplement: Copper gluconate Drug: Temozolomide Phase 2

Detailed Description:
Glioblastoma is the most common malignant primary brain tumor and one of the most devastating cancers. The current standard of care for glioblastoma includes maximal safe resection followed by radiotherapy and temozolomide, which results in a median progression-free survival of less than 7 months, and median overall survival (OS) of less than 15 months. Moreover, patients with unmethylated glioblastoma respond poorly to this current standard treatment. This clinical trial evaluates the potential role of continuous, upfront use of Disulfiram in combination with Copper gluconate in enhancing temozolomide effect in the treatment of unmethylated GBM patients.

Masking: None (Open Label)
Primary Purpose: Treatment
Official Title: A Phase II, Open-Label Study to Evaluate the Safety, Tolerability, and Efficacy of Disulfiram and Copper Gluconate When Added to Standard Temozolomide Treatment in Patients With Newly Diagnosed Resected Unmethylated Glioblastoma Multiforme
Actual Study Start Date : March 28, 2018
Estimated Primary Completion Date : December 31, 2021
Estimated Study Completion Date : December 31, 2022

Arm Intervention/treatment
Experimental: DSF-Cu with temozolomide and radiation
Disulfiram (DSF; oral) / copper gluconate (Cu; oral) dosed at 125 mg / 2 mg, twice daily. Temozolomide will be administered following the standard Stupp protocol at a dose of 75 mg/m2 for 42 days with concurrent radiation therapy. Temozolomide maintenance dose will be 150 mg/m2 once daily on Days 1-5 of every 28-day cycle while DSF-Cu is continued twice daily, as tolerated, for the duration of the Temozolomide adjuvant treatment. Patients demonstrating continued benefit from the adjuvant temozolomide after 6 cycles can continue treatment to a maximum of 12 cycles
Drug: Disulfiram
Disulfiram is taken orally, twice daily.
Other Name: Antabuse

Dietary Supplement: Copper gluconate
Copper gluconate is taken orally, twice daily

Drug: Temozolomide
Temozolomide is taken once daily
Other Name: Temodar, Temodal, Temcad

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

Inclusion Criteria:

  • Age 18 or older
  • Diagnosis of histologically confirmed glioblastoma (WHO grade IV). Subjects with an original histologic diagnosis of low grade glioma or anaplastic glioma (WHO grade II or III) are eligible if a subsequent histological diagnosis of glioblastoma is made
  • Patients whose tumor is determined to be unmethylated
  • Patients with incomplete resection as determined by residual, measurable gadolinium or contrast-enhancing lesion or lesions
  • Recent resection of glioblastoma within 4 weeks of study entry. Patients who have only had a tumor biopsy and who are considered unresectable are eligible (but based on the study accrual this subset of patients with unresectable tumor may be considered for separate analysis)
  • ECOG PS of ≤ 2 (see appendix A)
  • Willing to remain abstinent from consuming alcohol while on DSF
  • No prior radiation or chemotherapy
  • Meets the following laboratory criteria:

    • Absolute neutrophil count ≥ 1,500/mcL
    • Platelets ≥ 100,000/mcL
    • Hemoglobin > 10.0 g/dL (transfusion and/or ESA allowed)
    • Total bilirubin and alkaline phosphatase ≤ 2x institutional upper limit of normal (ULN)
    • Aspartate aminotransferase (AST) and alanine aminotransferase (ALT) < 3 x ULN
    • Blood urea nitrogen (BUN) and creatinine < 1.5 x ULN
  • Able to take oral medication
  • Able to understand and willing to sign an institutional review board (IRB)-approved written informed consent document (legally authorized representative permitted)

Exclusion Criteria:

  • Radiographic evidence of leptomeningeal dissemination, extensive intraparenchymal dissemination, infratentorial tumor, or metastatic disease to sites remote from the supratentorial brain
  • Enrolled in another clinical trial testing a novel therapy or drug
  • Received prior radiation therapy or chemotherapy for glioblastoma
  • History of allergic reaction/hypersensitivity to DSF (without alcohol) or copper.
  • Treatment with the following medications that may interfere with metabolism of DSF: warfarin (unless otherwise chosen by the study PI who will actively adjust Coumadin dose to consistently maintain a safe, therapeutic INR < 3), theophylline, amitriptyline, isoniazid, metronidazole, phenytoin, phenobarbital, chlorzoxazone, halothane, imipramine, chlordiazepoxide, diazepam. (Note: lorazepam and oxazepam are not affected by the P450 system and are not contraindicated with DSF).
  • Active severe hepatic or renal disease
  • Grade 2 or higher peripheral neuropathy or ataxia per NCI CTCAE version 4.0 (2009)
  • History of idiopathic seizure disorder schizophrenia, or psychosis unrelated to glioblastoma, corticosteroid, or anti-epileptic medications
  • History of Wilson's or Gilbert's disease
