The Biologics License Application (BLA) for teplizumab for the delay or prevention of type 1 diabetes (T1D) in at-risk individuals has been submitted to the Food and Drug Administration (FDA).

The BLA is supported by data from a phase 2 trial that evaluated whether teplizumab, an anti-CD3 monoclonal antibody, could prevent or delay the onset of T1D in at-risk individuals. Relatives of patients with T1D were randomized to receive intravenous infusions of either teplizumab (n=44) or placebo (n=36) for 14 consecutive days; oral glucose tolerance tests were used to assess progression to clinical T1D every 6 months. 

Findings from an extended follow-up showed that treatment with teplizumab significantly delayed progression to clinical T1D by a median of approximately 3 years compared with placebo in this patient population. Additionally, teplizumab treatment was reported to significantly reverse the decline in C-peptide levels.
