Is this trial a fit for you?

Likely a good fit

Ideal candidates are children or adults with Stage 1b or Stage 2 type 1 diabetes who have at least two diabetes‑related autoantibodies and weigh at least 8 kilograms.

Probably not a fit

People with other types of diabetes, established clinical (Stage 3) type 1 diabetes, or those with uncontrolled cardiovascular disease, recent serious infections, a high risk of venous thromboembolism, lymphoproliferative disease, or malignancy would not be expected to benefit and are excluded.

A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.

What this trial studies

This Phase 3, randomized, placebo‑controlled trial gives at‑risk participants either baricitinib or matching placebo and follows them for up to about five years to see if treatment delays progression to clinical (Stage 3) type 1 diabetes. Eligible participants have Stage 1b or Stage 2 disease with at least two diabetes‑related autoantibodies and weigh at least 8 kilograms. Key exclusions include other types of diabetes, uncontrolled high blood pressure, recent serious infections, cardiovascular events or heart failure, and a history or high risk of venous thromboembolism, lymphoproliferative disease, or malignancy. Study visits occur at several U.S. sites for regular monitoring, laboratory testing, and safety assessments.

Why it matters

Potential benefit: If successful, baricitinib could delay the clinical onset of type 1 diabetes, helping preserve insulin‑producing beta cell function and postponing the need for insulin therapy.

How similar studies have gone: Some immune‑modulating therapies (for example, teplizumab) have shown the ability to delay onset of clinical type 1 diabetes, but using the JAK inhibitor baricitinib for this purpose is relatively novel with limited prior clinical data.
