Abciximab Overview

Introduction of Abciximab

Abciximab (also known as abcixifiban or c7E3 Fab), is the Fab fragment of the chimeric human-murine, monoclonal antibody 7E3. It is composed of murine variable regions and human constant regions. Abciximab directed against the intact platelet GPIIb/IIIa (Glycoprotein IIb/IIIa) receptor and inhibits platelet aggregation. The drug was manufactured by Janssen Biologics BV and distributed by Eli Lilly under the trade name ReoPro. This Fab fragment is produced by continuous perfusion in mammalian cell culture and purified from cell culture supernatant by a series of steps including specific viral inactivation and removal procedures, digestion with papain and column chromatography. It was approval by the U.S. Food and Drug Administration early in 1994 mainly used during and after the percutaneous coronary intervention to prevent platelets form sticking together and cardiac ischemic complications in patients undergoing percutaneous coronary intervention or in patients with unstable angina not responding to conventional medical therapy when percutaneous coronary intervention is planned within 24 hours.

Mechanism of Action of Abciximab

The target receptor GPIIb/IIIa, also known as integrin αIIbβ3, is a complex formed via calcium-dependent association of gpIIb and gpIII. GPIIb/IIIa is found on the platelets surface and functions as s receptor for fibrinogen and von Willebrand factor and aids platelet activation. It was found that GPIIb/IIIa is in an inactive conformation in resting platelets, which is unable to bind to its primary ligands. During activation, the confirmation of the extracellular domain of GPIIb/IIIa changes into an active form that is much affinity for its ligands. Activated GPIIb/IIIa is essential for platelet aggregation as it is considered the final step in platelet activation leading to aggregation. Thus, GPIIb/IIIa becomes a target of several drug treatment for platelet aggregation. Abciximab is designed to binds to the intact platelets GPIIb/IIIa receptor, which alters the conformation and blocks access of large molecules to the receptor. In addition, abciximab also prevents effects by vitronectin receptor through binding to this integrin.
