This multi-center randomized controlled trial will assess the safety and efficacy of ATG followed by either adalimumab or verapamil in preserving insulin secretion 2 years from randomization in persons aged 9 to \<21 with recent-onset stage 3 T1D.

Eligibility criteria

Qualifiers

At least one positive T1D auto-antibody.

If clearly positive (≥20% above local lab's ULN) at screening, repeat antibody testing for central lab is not required.

Insulin auto-antibodies are only considered if exogenous insulin use is <10 days when blood is drawn.

Must have stimulated C-peptide levels ≥0.2 pmol/mL measured during MMTT conducted prior to randomization.

Disqualifiers

Prior treatment with ATG or known allergy to ATG or rabbit-derived products.

Immunodeficient or have clinically significant chronic lymphopenia: Leukopenia (<3,000 leukocytes /μL), neutropenia (<1,500 neutrophils/μL), lymphopenia (<800 lymphocytes/μL).

Thrombocytopenia (<100,000 platelets/μL) or anemia (hemoglobin < 10g/dL).

Leukocytosis (>14,000/mL)
