Imatinib Treatment in Recent Onset Type 1 Diabetes Mellitus

Type 1 diabetes mellitus (T1DM) results from the autoimmune destruction of insulin-producing ß cells. Although exogenous insulin is widely available, it is not possible for affected individuals to consistently achieve euglycemia with current technology, and thus they are at risk for devastating long-term complications. This phase II study is designed to evaluate the safety and efficacy of imatinib mesylate as a novel therapy for new-onset T1DM. Imatinib is a first-in-class tyrosine kinase inhibitor. This study will explore the potential role of short-term therapy with imatinib to induce tolerance and possibly lead to a durable long-term remission of T1DM.

Eligible participants will be randomized to receive either imatinib mesylate or placebo daily. All participants randomized into this study will be seen at a study site for a follow-up evaluation, 2 weeks and 4 weeks after randomization, and every month month thereafter for the first year. Participants will come in for a visit ever 6 months for the second year. At the study visits, participants will undergo assessments of their insulin production, immunologic status, and overall health. Subjects will be followed until the conclusion of the study. The trial is expected to last approximately 2-4 years or until the required amount of information is gathered.
