Can these pills save Insulin-Making cells in newly diagnosed type 1 diabetes?

NCT ID NCT05743244

First seen Jun 27, 2026 · Last updated Jun 27, 2026

Summary

This phase 2 trial tests two oral drugs, abrocitinib and ritlecitinib, in 78 people aged 12-35 who were diagnosed with type 1 diabetes within the last 100 days. The goal is to see if these JAK inhibitors can help preserve the body's ability to produce insulin, measured by a stimulated C-peptide test after 12 months. Participants are randomly assigned to receive one of the drugs or a placebo, and the study is double-blind, meaning neither patients nor doctors know who gets what.

What this could mean

Our plain-language read of the trial. This is informational only — not medical advice or a prediction.

Active substance

Abrocitinib and Ritlecitinib (JAK inhibitor drugs)

What this could lead to

If successful, this could lead to a treatment that helps people with newly diagnosed type 1 diabetes keep making some of their own insulin for longer, reducing the need for injected insulin.

What could go wrong

This is an early phase 2 trial with only 78 people, so results may not apply to everyone. JAK inhibitors can have side effects like increased infection risk, and the drugs may not work as hoped.
