Description
Summary
A multi-center, placebo-controlled, double blind, 1:1:1 randomized control clinical trial testing two different JAK Inhibitors abrocitnib, ritlecitinib, and placebo in subjects with recent onset Stage 3 Type 1 Diabetes within 100 days of diagnosis.
Official Title
A Phase 2 Multi-Center, Randomized, Double-Blind, Placebo-Controlled Study to Evaluate the Safety and Efficacy of Subtype-Selective JAK Inhibitors for Preservation of Pancreatic β Cell Function in Newly Diagnosed Type 1 Diabetes Mellitus
Details
This study has a total sample size of 78 participants. Of that 78, 52 participants will receive active treatment, and a total of 26 participants will receive placebo. Participants will receive 12 months of active treatment with abrocitinib, ritlecitinib, or placebo with up to 12 months of additional follow-up. During the study, participants will undergo frequent assessments of their insulin production, immunologic status, overall health and well-being and diabetes care.

killed influenza vaccination at least 2 weeks prior to the baseline visit (V0) when vaccine for the current or upcoming flu season is available. Enrollment must be delayed at least 4 weeks from administration of a killed vaccine other than influenza and 6 weeks from a live vaccination. Vaccinations should not be given while on study drug and be postponed at least 3 months after the last dose of study drug.

should receive an authorized non-live COVID-19 vaccination series or COVID-19 vaccine at least 2 weeks prior to the baseline visit (V0).
12. If participant is female with reproductive potential, she must have a negative
pregnancy test at screening and be willing to avoid pregnancy using a highly-effective contraceptive method for the duration of the study
13. Males of reproductive age must use a highly-effective contraceptive method during the
treatment phase and for 3 months following last dose of study drug
