Eligibility Criteria

• Age: 12 Years - 35 Years
• Sex: all
• Healthy Volunteers: No
• Age Groups: Child (0-17), Adult (18-64)

You may qualify if:

• Diagnosis of Type 1 Diabetes Mellitus based on American Diabetes Association (ADA) criteria and ≤100 days since diagnosis, defined as the first day of insulin administration (subjects must be able to be randomized within the 100-day period from diagnosis) .
• Adequate glycemic control for \>14 days, defined as 3 consecutive fasting glucose levels by self-administered blood glucose (SMBG) or lab testing at \<130 mg/dL.
• Age at randomization of 12.0 - \<18.0 years (adolescent), 18.0 - \<36.0 years of age (adult) ..
• HbA1c \<10.0% based on point-of-care or local lab measurement.
• Measurement can be repeated every 5-7 days if \>10.0%.
• Presence of antibodies to at least one of the following antigens: GAD-65, IA-2, ZnT8; or insulin, if obtained within 10 days of the onset of exogenous insulin therapy.
• Willingness to wear a continuous glucose monitoring (CGM) device for specified periods of time.
• Written informed consent, including authorization to release health information and assent for adolescent subjects.
• Willingness and ability of subject or adult guardian to comply with all study procedures of the study protocol, including attending all clinic visits.

You may not qualify if:

• Body Mass Index (BMI) \>30 kg/m2 for adults; \>95 percentile BMI-for-age for subjects under 18 years of age.
• Previous immunotherapy for T1D.
• Diagnosis of liver disease or hepatic enzymes, as defined by ALT and/or AST ≥2.5 times the upper limit of normal (ULN).
• Hematology: white blood cells (WBC) \<3 x 109/L; platelets \<100 x 109/L; hemoglobin \<10.0 g/dL. (Low WBC values may be repeated every 3-7 days, and results to be discussed with the Medical Monitor.)
• Serum creatinine \> 1.5 times ULN.
• History of malignancy, except for cancers in remission \>5 years, or basal cell or in situ squamous cell carcinoma of the skin.
• Significant cardiovascular disease (including inadequately controlled hypertension, history of myocardial infarction, angina, use of anti-anginal medicines (e.g., nitroglycerin), or abnormal stress test, which, in the opinion of the Principal Investigator (PI), would interfere with participation in the trial.
• Immunosuppressive therapy (systemic corticosteroids, cyclosporine, azathioprine, or biologics) within 30 days of screening.
• Current or prior (within the last 30 days) use of metformin, sulfonylureas, glinides, thiazolidinediones, GLP1-RAs, DPP-IV inhibitors, pramlintide, or SGLT-2 inhibitors.
• Current use of verapamil or α-methyldopa.
• History of any organ transplant, including islet cell transplant.
• Active autoimmune or immune deficiency disorder other than T1D or well-controlled autoimmune thyroid disease (e.g., sarcoidosis, rheumatoid arthritis, moderate-to-severe psoriasis, inflammatory bowel disease, and other autoimmune conditions that may require treatment with TNF or other biologics), unless approved by the Medical Monitor.
• Thyroid-stimulating hormone (TSH) at screening \>2.5 mIU/L.
• History of adrenal insufficiency.
• Evidence of infection with HBV (as defined by hepatitis B surface antigen (HBsAg)), HCV (anti-HCV antibodies), or HIV.
