Teplizumab, sold under the brand name Tzield, is a humanized anti-CD3 monoclonal antibody that is the first approved treatment indicated to delay the onset of stage 3 type 1 diabetes (T1D) in people with stage 2 T1D. [3] [4] [5] The Fc region of this antibody has been engineered to have Fc receptor non-binding (FNB) properties. [6]
A general representation of the method used to produce monoclonal antibodies [1] [2] A monoclonal antibody (mAb, more rarely called moAb) is an antibody produced from a cell lineage made by cloning a unique white blood cell. All subsequent antibodies derived this way trace back to a unique parent cell.
People have had severe infusion-related reactions to pembrolizumab. There have also been severe immune-related adverse effects including lung inflammation (including fatal cases) and inflammation of endocrine organs that caused inflammation of the pituitary gland, of the thyroid (causing both hypothyroidism and hyperthyroidism in different people), and pancreatitis that caused Type 1 diabetes ...
This list of over 500 monoclonal antibodies includes approved and investigational drugs as well as drugs that have been withdrawn from market; consequently, the column Use does not necessarily indicate clinical usage. See the list of FDA-approved therapeutic monoclonal antibodies in the monoclonal antibody therapy page.
The advantage of active monoclonal antibody therapy is the fact that the immune system will produce antibodies long-term, with only a short-term drug administration to induce this response. However, the immune response to certain antigens may be inadequate, especially in the elderly.
People with type 1 diabetes experience diabetic ketoacidosis 1–5 times per 100 person-years, the majority of which result in hospitalization. [94] 13–19% of type 1 diabetes-related deaths are caused by ketoacidosis, [91] making ketoacidosis the leading cause of death in people with type 1 diabetes less than 58 years old. [94]
Newer monoclonal antibodies with the same mechanism of action include otelixizumab, teplizumab and visilizumab. They are being investigated for the treatment of other conditions like Crohn's disease, ulcerative colitis and type 1 diabetes, [1] and for inducing immune tolerance. [2] [3]
Muromonab-CD3 is a murine anti-CD3 monoclonal antibody of the IgG2a type that was previously used to prevent T-cell activation and proliferation by binding the T-cell receptor complex present on all differentiated T cells. As such it was one of the first potent immunosuppressive substances and was administered to control the steroid- and/or ...
