Subjects will undergo prescreening for genetic typing and then screening procedures up to 28 days prior to the first dose to determine eligibility. T1D adults between 18 and 45 years of age, inclusive, who are positive for at least one gene encoding for HLA-DQ8 (DQA1\\*0301, DQB1\\*0302) will be enrolled.\n\nEach cohort will include 6 subjects on active drug, and the study will include 6 subjects total on placebo. Each cohort will participate in a 2-week dosing period. Enrollment of the cohorts will be sequentially staggered such that initial safety data after the first four subjects assigned to active treatment complete one week of treatment in each cohort will be reviewed before the next ascending dose cohort is enrolled. The safety reviews will include cumulative safety data for all subjects to that point. Subjects will have 5 scheduled clinic visits: screening, first day of dosing, 1 week after dosing begins, 2 weeks after dosing begins (end of treatment), and 1 week following the final dose. Subjects will self-administer study drug on non-clinic treatment days. Safety assessments will be conducted at all study visits. Insulin use (dose and frequency) will be monitored.\n\nPharmacokinetic (PK) assessments will be evaluated at every visit during the treatment period to characterize the following: single dose PK, trough PK and steady PK. Pharmacodynamic (PD) and immunological assessments will be evaluated before, during and after treatment.'}, 'eligibilityModule': {'sex': 'ALL', 'stdAges': ['ADULT'], 'maximumAge': '45 Years', 'minimumAge': '18 Years', 'healthyVolunteers': False, 'eligibilityCriteria': "Inclusion Criteria:\n\n1.
