Disulfiram for Preventing Treatment Complications in Patients Undergoing CAR T-cell Therapy for Relapsed or Refractory Diffuse Large B-cell Lymphoma

5. november 2026 opdateret af: University of Michigan Rogel Cancer Center

A Single Center, Phase I/II Study of Disulfiram for the Prevention of Immunotoxicity in Patients Undergoing CAR T-Cell Therapy

This phase I/II trial tests the safety, best dose, and effectiveness of disulfiram for preventing treatment complications in patients with large B-cell lymphoma that has come back after a period of improvement (relapsed) or that does not respond to treatment (refractory) and who are undergoing chimeric antigen receptor (CAR) T-cell therapy. Two major complications of CAR T-cell therapy include cytokine release syndrome (CRS) and immune effector cell-associated neurotoxicity syndrome (ICANS). CRS results from inflammation in the body when the immune system responds too aggressively to the modified T cells working to attack cancer cells. ICANS is inflammation of the brain or nerves. CRS is most often a prelude to ICANS, and both of these toxicities currently require immunosuppression for treatment, which can inhibit CAR T-cell response. Disulfiram has been found to impact several biologic pathways that cause CRS. Disulfiram may be safe and effective for reducing the incidence and severity of reactions to CAR T-cell therapy without inhibiting CAR T-cell response.

Patients with Gilbert syndrome or underlying primary malignancy involving the liver with total bilirubin >= 2.5 x ULN (or absolute total bilirubin >= 3 mg/dL) should be excluded. Aspartate aminotransferase (AST): >= 2.5 x ULN, alanine aminotransferase (ALT): >= 2.5 x ULN

    • Parkinson's disease
    • Psychosis
  • Any other significant medical condition (including neurological or psychiatric) which, in the opinion of the investigator, places the participant at an unacceptable risk for treatment-related complications, could interfere with the successful or safe delivery of therapy, or could interfere with evaluation of study intervention or interpretation of participant safety or study results. Including but not limited to:

    • Diabetes with associated autonomic dysfunction
    • Uncontrolled Hypothyroidism
    • Chronic or acute nephritis
    • Hepatic cirrhosis/insufficiency
  • Pregnant or nursing females

  • Current or previous treatment with any other agents explicitly for prophylaxis of CRS or ICANS, including corticosteroids and investigational agents during the study enrollment period. Corticosteroids given for disease treatment should have a washout of at least 5 half-lives prior to cell infusion. Use of prophylactic antiseizure medications is not contraindicated

  • History of, or a concurrent, clinically significant illness, medical condition or laboratory abnormality that, in the investigator's opinion, could affect the conduct of the study

  • Concurrent use of prohibited medications or substances at risk of precipitating a disulfiram reaction

  • Hypersensitivity to disulfiram or to other thiuram derivatives used in pesticides and rubber vulcanization
