Open-Label Study of Dimethyl Fumarate in Adults With Type 1 Diabetes

This is a non-randomized, parallel-controlled, single-center, open-label clinical trial designed to evaluate the efficacy of dimethyl fumarate in preserving pancreatic beta-cell function in adults with type 1 diabetes, as well as its safety and tolerability in this population. Eligible participants are adults aged 18 to 65 years who meet the ADA 2024 diagnostic criteria for type 1 diabetes, have at least 2 positive islet autoantibodies, and have residual beta-cell function as evidenced by a random C-peptide level of at least 200 pmol/L. A total of 96 participants are planned for enrollment, including 32 in the dimethyl fumarate treatment group and 64 in the standard-treatment control group. Participants in the treatment group will receive dimethyl fumarate enteric-coated capsules in addition to standard insulin therapy for type 1 diabetes. Dimethyl fumarate will be initiated at 120 mg twice daily and increased after 7 days to a maintenance dose of 240 mg twice daily. Participants in the control group will receive standard insulin therapy alone. The intervention period will be 24 weeks, followed by 52 weeks of follow-up. The primary efficacy endpoint is the baseline-adjusted geometric mean area under the serum C-peptide curve during a 2-hour mixed-meal tolerance test at Week 24. Secondary endpoints include measures of beta-cell function at multiple time points, changes in glycated hemoglobin, proportions of participants with good or poor glycemic control, insulin dose requi…
