# Pexelizumab

Pexelizumab is a drug designed to reduce side effects of coronary artery bypass grafting and angioplasty, among other types of cardiac surgery. It is a single chain variable fragment of a monoclonal antibody targeted against component 5 of the complement system.

## Current status

Alexion, the developer of pexelizumab, stopped development when the phase 3 trial indicated the heart-attack drug is no better than placebo.
