Introduction: Type 1 diabetes (T1DM) is an immune-mediated disease induced by antigen-specific T cells infiltrating pancreatic beta cells leading to the progressive loss of endogenous insulin secretion. Areas covered: The identification of specific components of the autoimmune response favoured the implementation of several immunomodulatory therapies including antiCD3 monoclonal antibody (mAb) called otelixizumab. Otelixizumab is a chimeric monoclonal antibody that targets the e-chain of the CD3T-lymphocyte surface receptor that has been developed with the aim of short therapeutic courses capable of inducing a remission of T1DM. Clinical trials have been carried out with otelixizumab to evaluate its safety and efficacy, but despite positive results of Phase I and II studies, the results of Phase III studies have been contradictory. Expert opinion: High doses of otelixizumab have shown beneficial effects on beta cell function whereas a lower dose, which was tested to avoid the adverse effects associated with higher doses, was not effective on beta cells preservation. We believe that otelixizumab is a drug of potential interest for treating new onset T1DM patients and its use in combination with other immunomodulatory agents should be considered as a solution to circumvent adverse effects while maintaining efficacy.

Abstract

Introduction: Type 1 diabetes (T1DM) is an immune-mediated disease induced by antigen-specific T cells infiltrating pancreatic beta cells leading to the progressive loss of endogenous insulin secretion. Areas covered: The identification of specific components of the autoimmune response favoured the implementation of several immunomodulatory therapies including antiCD3 monoclonal antibody (mAb) called otelixizumab. Otelixizumab is a chimeric monoclonal antibody that targets the e-chain of the CD3T-lymphocyte surface receptor that has been developed with the aim of short therapeutic courses capable of inducing a remission of T1DM. Clinical trials have been carried out with otelixizumab to evaluate its safety and efficacy, but despite positive results of Phase I and II studies, the results of Phase III studies have been contradictory. Expert opinion: High doses of otelixizumab have shown beneficial effects on beta cell function whereas a lower dose, which was tested to avoid the adverse effects associated with higher doses, was not effective on beta cells preservation. We believe that otelixizumab is a drug of potential interest for treating new onset T1DM patients and its use in combination with other immunomodulatory agents should be considered as a solution to circumvent adverse effects while maintaining efficacy.
