Brief Summary:

This clinical trial evaluates the safety, efficacy, and biomarker levels of FDA-approved drug disulfiram in the treatment of adult subjects hospitalized with moderate COVID-19. Disulfiram may limit the hyperinflammatory response associated with COVID-19 and reduce the risk of progression to severe illness.

Subjects will be screened and randomized to receive either daily administration of oral disulfiram or placebo for 14 days. Subjects will be followed up on Day 28.


Condition or disease Intervention/treatment Phase
Covid19 Drug: Disulfiram Drug: Placebo Phase 2

Detailed Description:

COVID-19 is a respiratory disease caused by a novel coronavirus (SARS-CoV-2) and causes substantial morbidity and mortality. There is currently no vaccine to prevent COVID-19 or infection with SARS-CoV-2 or therapeutic agent to treat COVID-19. The ongoing COVID-19 pandemic has demonstrated increased risk to those with an aging immune system. The elderly and those with comorbidities are reported as being the most susceptible to COVID-19, which may be due to a higher basal state of inflammation ("inflammaging") and a primed inflammasome pathway. Disulfiram, an FDA-approved drug for the treatment of alcohol dependence, has a potential for limiting the hyperinflammatory response associated with COVID-19. Specifically, the drug inhibits gasdermin D pore formation, reducing pyroptosis and netosis and could target the root cause of hyperinflammation, weakening the cytokine storm and therefore reducing the risk of progression to severe illness.

This is a stratified, randomized, double-blind, placebo-controlled study of disulfiram in hospitalized subjects over the age of 50 diagnosed with moderate COVID-19. Up to 200 subjects are planned to be enrolled and randomized (1:1) to either receive 500 mg of disulfiram (active product) or placebo, orally (po) or enterally (only in patients that require mechanical ventilation) once daily for fourteen (14) days in addition to standard of care. Stratification will be done at randomization based on age and comorbidities.

Study Type : Interventional  (Clinical Trial)
Actual Enrollment : 140 participants
Allocation: Randomized
Intervention Model: Parallel Assignment
Intervention Model Description:

Subjects will be randomized to receive either the active product (disulfiram) or placebo.

Disulfiram will be dosed 500 mg daily for a total of 14 days of treatment. A matching placebo will be given using the same dosing schedule.

Masking: Quadruple (Participant, Care Provider, Investigator, Outcomes Assessor)
Masking Description: In order to minimize bias due to key baseline characteristics that can impact clinical outcomes, the randomization will be stratified 1:1 to placebo or active product based on age and comorbidities.
Primary Purpose: Treatment
