Inclusion and exclusion lines below are quoted from ClinicalTrials.gov. No match score is shown, because a score needs a person's age, biomarkers, and treatment dates. Confirm the record with the study team.
Rheumatoid arthritis (RA) is a chronic autoimmune disease characterized by persistent joint inflammation and systemic immune activation. Obesity is common among individuals with RA and is associated with increased disease activity, reduced treatment response, and worse functional outcomes. Inflammation in adipose tissue, driven in part by activation of the NLRP3 inflammasome and downstream gasdermin D (GSDMD)-mediated pathways, may contribute to systemic inflammation and RA disease severity. Disulfiram (DSF), an FDA-approved medication for alcohol use disorder, has recently been identified as an inhibitor of GSDMD-mediated inflammatory signaling and pyroptosis. Preclinical studies suggest that DSF reduces inflammasome activation, inflammatory cytokine release, and metabolic dysfunction. This study is a 12-week, randomized, double-blind, placebo-controlled pilot trial designed to evaluate the safety, tolerability, and preliminary efficacy of DSF in overweight and obese adults with active RA despite stable disease-modifying antirheumatic drug (DMARD) therapy. Participants will be randomized to receive either DSF (250 mg daily) or placebo....
