Objective
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.
Description
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.

Participate in a study
Here are some general steps to consider when participating in a research study:
-
Step1
Contact the research team
Call or email the research team listed within the specific clinical trial or study to let them know that you're interested. A member of the research team, such as the researcher or study coordinator, will be available to tell you more about the study and to answer any questions or concerns you may have.
-
Step2
Get screened to confirm eligibility
You may be asked to take part in prescreening to make sure you are eligible for a study. The prescreening process ensures it is safe for you to participate. During the prescreening process, you will be asked some questions and you may also be asked to schedule tests or procedures to confirm your eligibility.
-
Step3
Provide your consent to participate
If you are eligible and want to join the clinical trial or study, a member of the research team will ask for your consent to participate. To give consent, you will be asked to read and sign a consent form for the study. This consent form explains the study's purpose, procedures, risks, benefits and provides other important information, such as the study team's contact information.
-
Step4
Participate
If you decide to participate in a clinical trial or study, the research team will keep you informed of the study requirements and what you will need to do to throughout the study. For some trials or studies, your health care provider may work with the research team to ensure there are no conflicts with other medications or treatments.
