Two-Drug cocktail may slow type 1 diabetes progression

NCT ID NCT03929601

First seen Feb 28, 2026 · Last updated May 15, 2026 · Updated 9 times

Summary

This study tests whether giving two immune-calming drugs, rituximab followed by abatacept, can help people newly diagnosed with type 1 diabetes keep making their own insulin longer than rituximab alone. About 74 participants aged 8 to 45 will receive the combo or a placebo over 48 months. The goal is to see if the combination better preserves beta-cell function, potentially reducing long-term insulin dependence.
