Eligibility Criteria
You may qualify if:
- Willing to provide Informed Consent
- Participants must live in a location with rapid access to emergency medical services
- Age 18-45 years (both inclusive) at the time of signing informed consent
- Must have a diagnosis of T1D for less than 48 months at randomization
- Must have at least one diabetes-related autoantibody present (GAD65A; mIAA, if obtained within 10 days of the onset of insulin therapy; IA-2A; ICA; or ZnT8A)
- Must have stimulated C-peptide levels greater than or equal to 0.2 pmol/ml measured during an MMTT conducted at least 21 days from diagnosis of diabetes and within one month (37 days) of randomization
- Be willing to comply with intensive diabetes management
- HbA1c ≤8.5% at screening
- Subjects who are CMV and/or EBV seronegative at screening must be CMV and/or EBV PCR negative within 37 days of randomization and may not have had signs or symptoms of a CMV and/or EBV compatible illness lasting longer than 7 days within 37 days of randomization
- Be up to date on recommended immunizations
- Be at least 6 weeks from last live immunization
- Be at least 4 weeks from killed vaccine other than flu vaccine
- Participants are required to receive killed influenza vaccination at least 2 weeks prior to randomization when vaccine for the current or upcoming flu season is available
- Be willing and medically acceptable to postpone live vaccines during the treatment period and for 3 months following last dose of study drug
- If participant is female with reproductive potential, she must have a negative pregnancy test at screening and be willing to avoid pregnancy using a highly effective contraceptive method for the 12 months of the study
- +2 more criteria
You may not qualify if:
- One or more screening laboratory values as stated
- Leukocytes \< 3,000/μL
- Neutrophils \<1,500 /μL
- Lymphocytes \<800 /μL
- Platelets \<100,000 /μL
- Haemoglobin \<6.2 mmol/L (10.0 g/dL)
- Potassium \>5.5 mmol/L or \<3.0 mmol/L
- Sodium \>150mmol/L or \< 130mmol/L
- AST or ALT ≥2.5 times the upper limits of normal
- Bilirubin ≥ 1.5 times upper limit of normal
- Glomerular Filtration Rate (eGFR) value of eGFR \< 60 ml/min/1.73 m2 as defined by KDIGO 2012 (43)
- Any other laboratory abnormality that might, in the judgment of the investigator, place the subject at unacceptable risk for participation in this trial
- Current or ongoing use of non-insulin pharmaceuticals that affect glycemic control within prior 7 days of screening
- Use of other immunosuppressive agents including chronic use of systemic steroids. Topical products are acceptable (nasal, conjunctival, skin)
- Have active signs or symptoms of acute infection at the time of randomization
