Teplizumab in Pediatric Stage 2 Type 1 Diabetes

This is a single-arm, non-randomized, open-label, multicenter study in the U.S. to assess the safety and pharmacokinetics of teplizumab in pediatric participants with Stage 2 type 1 diabetes (T1D) (two T1D-related autoantibodies and dysglycemia) who are 0 to \<8 years of age. Anti-drug antibodies/neutralizing antibodies (ADA/NAb) will also be assessed. Approximately 20 participants will be enrolled. The regimen consists of an intravenous infusion of teplizumab once daily for 14 consecutive days. The study duration for each individual may last up to approximately 26 months. The safety, tolerability, PK, ADA, and T1D clinical feature data will be summarized using descriptive statistics.
