Abstract
INTRODUCTION
Immunotherapies for type 1 diabetes mellitus (T1D) have been the focus of intense research over the past few decades; nevertheless, the results of clinical trials have not matched expectations. However, thanks to the recent and promising results on T1D prevention, among all the different immune-intervention tested strategies, clinical evidence on anti-CD3 monoclonal antibodies (mAb) deserve particular attention and in-depth evaluation.
AREAS COVERED
In this narrative review, we introduce the role of T-cells and their co-receptor CD3 in the pathogenesis of T1D and examine the potential of anti-CD3 mAbs as a treatment for preventing or curing T1D. We discuss pre-clinical studies, phase II/III clinical trials, testing the anti-CD3 mAb teplizumab in subjects at T1D high risk, and testing teplizumab and otelixizumab in T1D recent onset patients. In this work we discuss the current evidence gathered on anti-CD3 therapy to offer insights on the treatment strengths, limitations and unmet needs.
EXPERT OPINION
Recent phase II clinical trials with teplizumab in recent-onset T1D seem encouraging, but benefits associated with the use of anti-CD3 mAb in recent-onset T1D are still controversial. A better patient selection, based on immunological profiles and specific biomarkers, is crucial to improve clinical outcomes in T1D immunotherapies.
