This study will be a multicenter, double-blind, placebo-controlled, 2:1 random assigned, phase II clinical trial for individuals with recent onset type 1 diabetes. The investigators are conducting a double masked placebo-controlled intention to treat study enrolling persons with new onset T1D with documented continued residual C-peptide production. Within 45 days of screening and a run-in period during which eligibility will be determined and glycemic control optimized, subjects will have a 6-month double-masked treatment period with either DFMO or placebo. After a 6-month wash-out period the durability of effect will be assessed. Subjects will be randomly assigned either 1000mg/m2/day oral DFMO or placebo treatment at a 2:1 ratio.
The goal of this clinical trial is to test a drug known as DFMO in people with Type 1 Diabetes (T1D). The main question[s] it aims to answer are:~Does it reduce stress on the cells that make insulin?~Does it preserve what is left of the body's insulin production? Participants will take either DFMO or a placebo (looks like DFMO but has no active ingredients) two times a day for about 6 months. Participants will have 6 in person visits and 1 phone visit over a period of 12 months. Visits will include blood draws urine collection and other tests.
