Pilot Clinical Trial of Ustekinumab in Patients With New-onset T1D (UST1D)
In type 1 diabetes (T1D), immune defense cells in the body attack and destroy insulin-producing beta cells leaving affected people with a lifelong need for daily insulin injections. Even with insulin injections, blood glucose (sugar) control is imperfect and leads to many health complications and a shortened life span. This is a pilot clinical trial to test the safety of a drug, ustekinumab, in 20 adult subjects with recent-onset T1D. Ustekinumab is currently licensed for use in psoriasis where it has proven to be both highly effective and safe and so the investigators hope to see a similar effect in T1D. This trial will also be used to determine the best dosage and frequency of the drug to be given to people with T1D to help design future studies on the drug's effectiveness. The investigators hope that if the drug can block immune cells soon after the development of diabetes, any remaining insulin-producing cells may be protected, and regenerate, thus producing more insulin so that individuals may be insulin free, or require less insulin.

The investigators will perform an open-label pilot safety study (Phase I/II clinical trial) with a total of 20 adult (18-35 years old) subjects with recent-onset T1D. There will be four study cohorts, which will be recruited sequentially all to the treatment arm: five subjects will be given ustekinumab, 45mg subcutaneously (SC) at 0, 4, 16, 28 and 40weeks, five subjects will be given ustekinumab, 90mg SC at weeks 0, 4, 16, 28 and 40, five subjects will be given 45mg SC at weeks 0, 4 and 16 and five subjects will be given 90mg subcutaneously (SC) at weeks 0, 4 and 16. Recruitment and screening for the pilot study will be completed within the first 6 months. The follow up period is 1 year from the first dose.
