Current and experimental antibody-based therapeutics: insights, breakthroughs, setbacks and future directions

The premise of targeted therapy was born from an intimate understanding of the unique biological pathways and endpoints which are implicated in the development of different disease states and conditions. In addition, the identification of the most appropriate drugs to use for targeted drug therapy has aided in growing interest of the pharmaceutical industry to allocate more resources to monoclonal antibody (mAb) therapeutics. This being the case, it is important to understand antibody based therapeutics, some of the currently Food and Drug Administration (FDA)-approved mAbs in different disease states, as well as the future direction of mAb therapies. In this article, we will provide a critical overview, and discuss a selection of antibody based therapeutics, including their bioengineered structural and functional elements. Furthermore, a segment of the currently FDA-approved mAb antibody therapies, those in research, or in investigation for disease states and conditions ranging from autoimmune disease, inflammatory response, immunosuppression, cancer, including antibody-drug conjugates, immunotherapy, and exciting prospects for antiplatelet and antithrombotic monoclonal antibody therapeutics will be reviewed. Finally, we will discuss our predictions and aspirations for the future directions of mAb-based therapeutic interventions.
