Secondary outcome [7] 379727 0
The composite outcome assessing both the frequency, and when relevant, the severity of all adverse events.

Baricitinib is associated with an increased risk of infections including pneumonia, herpes zoster, urinary tract infections and cellulitis. Participants will be closely monitored for the development of signs and symptoms of infection during and after treatment with Baricitinib. This involves assessment by the study doctor and study nurse at each study visit as well as via regular telephone calls. Participants can also report any adverse events at any time via telephone contact, or in the participant diary which will be checked at each study visit.

Other possible adverse events include: low lymphocyte counts, low neutrophil counts, low haemoglobin levels, hepatotoxicity, lipid elevations and renal impairment. Such adverse events will be closely monitored via blood sample analysis for each participant at each study visit.
Timepoint [7] 379727 0
Adverse events will be assessed fortnightly from intervention commencement until 96 weeks post-intervention commencement. At each study visit during both the treatment period and the follow up period, blood samples will also be analysed to monitor for certain adverse events. Participants can also make contact at any point during this period to report any adverse events.

Study design
Purpose of the study
Treatment
Allocation to intervention
Randomised controlled trial
Procedure for enrolling a subject and allocating the treatment (allocation concealment procedures)
Allocation concealment performed.

Prior to study initiation, an independent researcher is responsible for generating the randomization schedule. Opaque envelopes numbered 1 through 80 with group name (active or placebo) will be provided to the pharmacists at each one of the study sites who will open them in sequence to assign the treatment. The study pharmacists will conceal the group assignment from study participants, investigators and study staff including the statistician.

Methods used to generate the sequence in which subjects will be randomised (sequence generation)
Stratified block randomization with variable block sizes of 3, 6 or 9 will be used to generate the randomization schedule. Age (less than 21 years, and greater than or equal to 21 years) will be used as a stratification factor.

Statistical methods / analysis
The sample size was selected based on estimates of 2-hour AUC mean C-peptide obtained from prior studies and using standard power calculations for comparison of treated and placebo groups. We propose to enrol 83 participants. Using standard equations for comparison of two means, a sample size of 50 baricitinib treated and 25 placebo treated participants with complete data is needed to provide 80% power to detect 45% increase in mean log(C-peptide+1) (0.306 vs. 0.445, sd of 0.2), in the treated group using a two-sample T-test at 0.05 level of significance (two-sided). With the expected 10% dropout rate the number of participants recruited into the study will be increased to 83 (55 and 28 in the intervention and control arms respectively). Should the number of drop-outs exceed 10%, additional participants may be recruited.

Statistical methods and analysis plan: The primary statistical hypothesis to be assessed is whether residual beta cell function (CPave at 48 weeks) will differ between those treated with baricitinib and placebo. The primary analysis will be performed based on intention to treat (ITT) with sensitivity analysis based on a per protocol basis to confirm the robustness of the findings.

Secondary outcomes will be assessed using ANOVA or Fisher’s exact test for continuous and categorical data respectively.

Safety results will be listed, tabulated using descriptive statistics, and plotted when appropriate.
