Brief Summary

Purpose of the Clinical Trial: This clinical trial aims to investigate whether dimethyl fumarate can treat adults with newly diagnosed type 1 diabetes and to evaluate the safety profile of dimethyl fumarate. Primary Research Questions: Does dimethyl fumarate protect pancreatic beta-cell function in adults with newly diagnosed type 1 diabetes? What medical issues may arise in individuals taking dimethyl fumarate? Study Design: Researchers will compare dimethyl fumarate with a placebo (an identical substance without active ingredients) to determine whether Dimethyl fumarate can effectively treat type 1 diabetes. Participant Activities: Take dimethyl fumarate or placebo orally twice daily for 24 weeks. Attend on-site visits every 4 weeks during the intervention period and every 12 weeks after the intervention for examinations and assessments. Record symptoms, blood glucose control, islet function, and insulin usage throughout the trial.
