All of the following are tumor necrosis factor blocking agents, EXCEPT:

Abciximab is a chimeric antibody that binds irreversibly to the GP IIb/IIIa antagonists. Etanercept is a human TNF receptor fusion protein consisting of two molecules of the ligand-binding poion of the TNF receptor (p75) fused to the Fc poion of IgG1. Etanercept binds soluble and membrane-bound TNF, thereby inhibiting the action of TNF. Infliximab is a mouse-human chimeric IgG1 monoclonal antibody that binds to soluble and membrane-bound TNF-. Infliximab is a complement-fixing antibody that induces complement-dependent and cell-mediated lysis when bound to cell-surface-bound TNF-. Adalimumab is a human IgG1 monoclonal antibody that binds soluble and membrane-bound TNF-. Like infliximab, it can mediate complement-induced cytolysis of cells expressing TNF.
