measure change in glycemic control and prandial insulin independency over 52 weeks with teplizumab compared with placebo, both administered by intravenous (IV) infusion, in participants with recently diagnosed Stage 3 type 1 diabetes (T1D) aged 1 to 25 years, on standard insulin therapy.', 'detailedDescription': 'The study duration for one participant will be approximately 84 weeks (18 months).'},

consent.\n* Participants diagnosed with T1D Stage 3 according to American Diabetes Association 2025 criteria\n* Participants able to be randomized and initiate study drug within 8 weeks (56 days) of the Stage 3 T1D diagnosis\n* Participants must be positive for at least one T1D autoantibody at screening:\n* Glutamic acid decarboxylase (GAD-65),\n* Insulinoma Antigen-2 (IA-2),\n* Zinc-transporter 8 (ZnT8), or\n* Insulin (if obtained not later than 14 days after exogenous insulin therapy initiation).\n* Islet cell cytoplasmic autoantibodies (ICAs)\n* Have random C-peptide level ≥0.2 nmol/L

of contraception for those participating in clinical studies.\n* A female participant is eligible to participate if she is not pregnant, and one of the following conditions applies:\n* Is a woman of nonchildbearing potential (WONCBP) OR\n* Is a woman of childbearing potential (WOCBP) and agrees to use a contraceptive method that is highly effective, with a failure rate of \\<1% during the study intervention period (to be effective before starting the intervention) and for at least 30 days after the last administration of study intervention.\n* A WOCBP must have a negative highly sensitive pregnancy test at screening (serum) and within 24 hours (urine or serum as required by local regulations) before the first administration of study intervention.\n* Lactating woman must interrupt breastfeeding and pump and discard breast milk during and for 20 days after last administration of study intervention.\n* Capable of giving signed informed consent as described in Appendix 1 of the protocol which includes compliance with the requirements and restrictions listed in the informed consent form (ICF) and in the protocol.\n\nNote: For minor participants, a specific ICF must also be signed by the participant's legally authorized representative (LAR).\n\nExclusion Criteria:\n\nParticipants are excluded from the study if any of the following criteria apply:\n\n* Participant has

antipsychotics, diphenylhydantoin, niacin).\n* Participant has previously received teplizumab or other anti-CD3 treatment.\n* Other medications not compatible or interfering with IMP at discretion of Investigator.\n* Current enrollment OR past participation in another investigational study in which an investigational intervention (eg, drug, vaccine, invasive device) was administered within the last 8 weeks or 5 half-lifes, whichever is longer, prior to screening.\n* Participant has any of the following laboratory parameters, at screening prior to first dose:\n* Lymphocyte count:
