Teplizumab therapy for type 1 diabetes mellitus
Teplizumab is a monoclonal antibody that binds to CD3 molecules on the surface of CD4+ and CD8+ T cells, both involved in the destruction of pancreatic beta cells
- Fc receptor-nonbinding anti-CD3 monoclonal antibodies such as Teplizumab have been studied in patients with T1DM
- teplizumab is an Fc receptor-nonbinding anti-CD3 episilon monoclonal antibody
- teplizumab is an Fc receptor-nonbinding anti-CD3 episilon monoclonal antibody
- Herold et al showed that a single course of teplizumab significantly slowed progression to clinical type 1 diabetes in high-risk, nondiabetic relativestives of patients with diabetes who had at least two autoantibodies and abnormal results of an oral glucose-tolerance test at trial entry (1)
- studies have detected an increase in C-peptide levels in early-onset type 1 diabetes patients treated with teplizumab
- this suggests that teplizumab leads to an improvement in beta cell function (2,3)
