About this study

Researchers are testing teplizumab compared with placebo in people with recently diagnosed stage 3 type 1 diabetes (T1D) aged 1 to 25 years. The trial will last for 1224 days and measure changes in glycemic control and prandial insulin independency over 52 weeks.

Based on ClinicalTrials.gov records.

Endpoints

Primary: For EU countries: Change from baseline in mean 2 hours mixed meal tolerance test (MMTT) stimulated C-peptide concentration, calculated from Area Under the Curve (AUC) in participants 5 years and older, For EU countries: HbA1c change from baseline, For United States (US) and non-European Union (EU) countries: Glycated hemoglobin (HbA1c) change from baseline

Secondary: Change from baseline in Time-in-Range (TIR) (70-180 mg/dL blood glucose) assessed by continuous glucose monitoring (CGM), Change from baseline in mean 2 hours MMTT stimulated C-peptide concentration, calculated from AUC, Incidence of participants with HbA1c ≤6.5% and requiring ≤0.25 IU/kg/day of insulin, Number of participants with treatment emergent adverse events (TEAEs), serious adverse events (SAEs), adverse events of special interest (AESIs) and TEAEs leading to treatment discontinuation, Teplizumab PK parameters: Area under the curve [AUC] and [AUClast], Teplizumab PK parameters: Maximum concentration of teplizumab [Cmax]
