Clinical Trial Summary

Type 1 diabetes (T1D) results from the killing of insulin-producing pancreatic beta cells by cells of the immune system. The study aims to slow the progressive, immune-mediated loss of insulin-producing beta cells that occurs after clinical presentation. The investigators have identified a pathway that is important for immune cells to kill beta cells, and a drug that will block this pathway and prevent beta cell death. This drug, baricitinib, is already in clinical use for rheumatoid arthritis, and is currently in clinical trials for other diseases, including childhood autoimmune diseases. It is hypothesized that baricitinib treatment for 48 weeks will preserve beta cell function in children and young adults with recently-diagnosed T1D.

The trial aims to recruit 83 participants aged 10-30 years who have been recently diagnosed with T1D. Two thirds of the participants will be randomly assigned to receive baricitinib, one third will receive placebo. The trial will test if baricitinib can slow the progressive loss of insulin-producing beta cells in these patients. The primary objective is to determine if baricitinib can reduce the loss of meal-stimulated plasma C-peptide, a measure of beta-cell function. Maintaining endogenous insulin in recent-onset T1D improves glucose control and may lead to long-term improvements in glucose and lower rates of serious diabetes complications and death.

11. Treatment with any investigational product within 30 days or 5 half - lives (whichever is longer) prior to baseline visit, or concurrent participation in a clinical trial with an investigational product or device;

12. Experienced any of the following within 12 weeks of screening: myocardial infarction, unstable ischemic heart disease, stroke, or New York Heart Association Stage IV heart failure;

13. Any serious medical condition within the previous 4 weeks which places the participant at an unacceptable risk if he or she were to participate in the study or confounds the ability to interpret data from the study, including, but not limited to, symptomatic cardiovascular, renal, respiratory, hepatic, gastrointestinal, endocrine, haematological and neurological conditions or psychiatric illness/social situations that would limit compliance with study requirements;

14. Have had any major surgery within 8 weeks prior to screening or will require major surgery during the study that, in the opinion of the investigator would pose an unacceptable risk to the participant;

15. History of chronic alcohol abuse or IV drug abuse or other illicit drug abuse within 2 years prior to screening.

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	The primary endpoint of the study is the change from baseline of plasma C-peptide area under the curve (AUC) over 2 hours following a mixed meal.		Measured at 48 weeks post commencement of intervention.
Secondary	Change from baseline in plasma C-peptide AUC over 2 hours following a mixed meal.		Measured at weeks 12, 24, 72 and 96 post commencement of intervention.
Secondary	Change from baseline in mean daily insulin use over 7 consecutive days.		Measured during the 2 weeks prior to the assessment at weeks 12, 24, 48, 72 and 96 post commencement of intervention.
Secondary	Change from baseline in glycosylated haemoglobin (HbA1c) levels.		Measured at weeks 12, 24, 48, 72 and 96 post commencement of intervention.
Secondary	Number of participants with responder status. Responder status is defined as glycosylated haemoglobin (HbA1c) less than or equal to 6.5 percent and mean daily insulin use less than 0.5 international units per kilogram per day (IU/kg/day).		Measured at weeks 12, 24, 48, 72 and 96 post commencement of intervention.
Secondary	Change in estimated C-peptide (CPEST) from baseline. CPEST is calculated based on six variable routine measures: disease duration, BMI, insulin dose, HbA1c, fasting plasma C-peptide and fasting plasma glucose.		Measured at weeks 12, 24, 48, 72 and 96 post commencement of intervention.
Secondary	Continuous glucose monitoring (CGM).		Measured at baseline, 12, 24, 48 and 96 weeks post commencement of intervention.
Secondary	The composite outcome assessing both the frequency, and when relevant, the severity of all adverse events.		Adverse events will be monitored throughout the entire study duration at weeks 0, 2, 4, 8, 12, 16, 20, 24, 36, 48, 72 and 96.
