Eligibility Criteria
Ages Eligible for Study
Accepts Healthy Volunteers
Description
Inclusion Criteria:
- Willing to provide informed consent or have a parent or legal guardian provide informed consent when the subject is <18 years of age.
- Age greater than or equal to 12 and < 35 years
- At least two or more diabetes-related biochemical autoantibodies (mIAA, GADA, ICA, IA-2A, ZnT8A) present on the same sample. In the absence of other antibodies, ICA and GADA positivity alone will not suffice for eligibility in this trial.
- Weight greater than the 5th percentile for age and sex.
- BMI < 95th and > 5th percentile for age for those under age 18 years and < 30 and > 15 for adults (≥ 18)
ADA Stage 2 criteria* AND at least one of the following high-risk markers (occurring at the same visit) within 7 weeks (52 days) of randomization, defined below (for defining a 2-year 50% risk for progression to Stage 3 T1D):
a. HbA1c ≥ 5.7 and <6.5% b. Index60 ≥ 1.4 i. Index60 = 0.3695 × (log fasting C-peptide [ng/mL]) + 0.0165 × 60-min glucose (mg/dL) - 0.3644 × 60-min C-peptide (ng/mL) c. DPTRS ≥ 7.4 DPTRS = (1.57 x log BMI) - (0.06 x age) + (0.81 x glucose sum from 30 to 120 min/100) - (0.85 x C-peptide sum from 30 to 120 min/10) + (0.48 x log fasting C-peptide)
*Dysglycemia is defined as 2-hr glucose ≥ 140 and <200 mg/dL or fasting glucose ≥ 110 and <126
- All subjects must be CMV and EBV PCR negative within 30 days of randomization and may not have had signs or symptoms of a CMV or EBV-compatible illness lasting longer than 7 days within 30 days of randomization
- Seated blood pressure less than 130/80 mmHg for participants ≥ 18 years. For participants < 18 years seated blood pressure less than 95th percentile for age, sex and height.
- Be at least 4 weeks from last live immunization
- Participants are required to receive non-live influenza vaccination at least 2 weeks prior to randomization when vaccine for the current or upcoming flu season is available.
- Participants are required to receive an authorized non-live COVID-19 vaccination and be fully vaccinated, including eligible boosters at least two weeks prior to randomization. Participants must also have a negative COVID-19 PCR test within 3 days of the first day of treatment.
- Willingness to comply with study directed social distancing and protection from SARS-Cov-2 infection.
- Be willing to forgo vaccines (other than killed influenza) during the 3 months after study drug treatment period (Days 0 and 1)
- Be up to date on all recommended vaccinations based on age of subject*
- With the exception of stage 2 T1D, subjects must be healthy, as defined by absence of any other untreated diagnoses that the protocol committee deems to be a potential confounder.
- If a female participant with reproductive potential, willing to avoid pregnancy (abstinence or adequate contraceptive method) through the completion of the study infusions and up to 3 months after study drug administration and undergo pregnancy testing prior to each study visit.
- Must be residing or have accommodations within 1 hour of the infusion site during the two days of study drug infusions and must be within 1 hour of a medical care facility for 1 day after completion of infusion 2.
Participants must live in a location with rapid access to emergency medical services.
- Adult subjects must be fully immunized. Pediatric subjects who have not completed their primary vaccination schedule must receive all vaccinations allowable per the AAP immunization guidelines for their current age prior to study drug delivery. Any remaining vaccinations should be given and continue per the schedule at least 3 months after study drug is administered.
Exclusion Criteria:
- Immunodeficiency or clinically significant chronic lymphopenia: (Leukopenia (< 3,000 leukocytes /μL), neutropenia (<1,500 neutrophils/μL), lymphopenia (<800 lymphocytes/μL), thrombocytopenia (<100,000 platelets/μL).
- Hemoglobin less than 13.5 g/dL for adult men and less than 12 g/dL for adult females and less than 11 g/dL for participants under age 18
- Active signs or symptoms of acute infection at the time of randomization including SARS-Cov-2.
- Uncontrolled autoimmune thyroid disease and/or celiac disease (participants must be well controlled for the previous 6 months).
- Evidence of prior or current tuberculosis infection as assessed interferon gamma release assay (QuantiFERON).
- Currently pregnant or lactating or anticipate getting pregnant within the study period.
- Require use of other immunosuppressive agents including chronic use of systemic steroids.
- Evidence of current or past HIV or Hepatitis B or current Hepatitis C infection.
- Any complicating medical issues or abnormal clinical laboratory results that may interfere with study conduct, or cause increased risk to include pre-existing cardiac disease, COPD, sickle cell disease, neurological disease, or blood count abnormalities.
- A history of malignancies other than of skin.
- Evidence of liver dysfunction with AST or ALT outside of the reference range.
- Evidence of renal dysfunction with creatinine outside of the reference range.
- Increased bilirubin (total and direct) outside of the normal limit (Participants with documentation of Gilbert's Disease permitted).
- Vaccination with a live virus within the last 4 weeks.
- Current or ongoing use of non-insulin pharmaceuticals that affect glycemic control within 7 days of screening
- Prior treatment with Teplizumab (either in a previous clinical trial or clinically).
- Has participated in a clinical trial for diabetes prevention previously and received active study agent within 3 months of randomization.
- Known allergy to ATG
- Prior treatment with ATG or known allergy to rabbit-derived products
- Prior adverse reactions to heparin.
- Any condition that in the investigator's opinion may adversely affect study participation will be reviewed by the Study Chair to ensure consistency and adjudicate whether or not the subject may compromise the study results
- Any screening/baseline laboratory result not otherwise stated out of normal reference range and/or medical history that may increase the risk of the subject's participation in this trial.
- Previously diagnosed with Stage 3 TID according to ADA criteria76 (see Appendix 3 for Criteria for diagnosis of diabetes)

Arms and Interventions
Participant Group / Arm |
Intervention / Treatment |
---|---|
Experimental: Antithymocyte globulin (ATG)
Antithymocyte globulin (ATG) will be intravenously administered over two days, with a total of 2 infusion periods.
The first infusion is given at baseline visit (day 1), the second is given the next day at baseline visit (day 2).
Body weight at baseline (Day 0- admission for the ATG/placebo infusion) will be used in calculating the doses for all infusions.
The first dose (0.5mg/kg) will be infused over a minimum of 4 hours, and the second dose (2mg/kg) over a minimum of 4 hours with a maximum infusion time for each infusion of 10 hours.
The second dose should be given no less than 12 and no more than 30 hours from the start of the first infusion.
The final prepared product is to be labeled to protect the blind.
Infusions may be administered either in a hospital or outpatient setting at the investigator's or institutions discretion.

Placebo Comparator: Placebo
0.9% Sodium Chloride Injection USP ("Normal" saline) is to be dispensed as the placebo for this study.
The placebo is to be prepared dispensing an infusion bag of 0.9% Sodium Chloride Injection USP ("Normal" saline) with no additives (no ATG, no premedications) and label the product to protect the blind.
The placebo will also be administered over a minimum of 4 hours for the first and second doses with a maximum infusion time of 10 hours.
The second dose of the placebo arm should be given no less than 12 and no more than 30 hours from the start of the first infusion.
Infusions may be administered either in a hospital or outpatient setting at the investigator's or institutions discretion.
