Alexion’s Soliris® (eculizumab) Receives Orphan Drug Designation for the Treatment of Neuromyelitis Optica (NMO)

Structure of eculizumab. Eculizumab was engineered to reduce immunogenicity and eliminate effector function. Human IgG2 and IgG4 heavy-chain sequences were combined to form a hybrid constant region that is unable to bind Fc receptors or to activate the complement cascade. Eculizumab exhibits high affinity for human C5, effectively blocking its cleavage and downstream proinflammatory and cell lytic properties. Reprinted from Rother et al with permission.

Eculizumab (INN and USAN; trade name Soliris) is a humanized monoclonal antibody that is a first-in-class terminal complement inhibitor and the first therapy approved for the treatment of paroxysmal nocturnal hemoglobinuria (PNH), a rare, progressive, and sometimes life-threatening disease characterized by excessive destruction of red blood cells (hemolysis). It costs £400,000 (US$600,000) per year per patient

Eculizumab also is the first agent approved for the treatment of atypical hemolytic uremic syndrome (aHUS), an ultra-rare genetic disease that causes abnormal blood clots to form in small blood vessels throughout the body, leading to kidney failure, damage to other vital organs and premature death.

In clinical trials in patients with PNH, eculizumab was associated with reductions in chronic hemolysis, thromboembolic events, and transfusion requirements, as well as improvements in PNH symptoms, quality of life, and survival.Clinical trials in patients with aHUS demonstrated inhibition of thrombotic microangiopathy (TMA),the formation of blood clots in small blood vessels throughout the body, including normalization of platelets and lactate dehydrogenase (LDH), as well as maintenance or improvement in renal function.

Eculizumab was discovered and developed by Alexion Pharmaceuticals and is manufactured by Alexion. It was approved by the United States Food and Drug Administration (FDA) on March 16, 2007 for the treatment of PNH, and on September 23, 2011 for the treatment of aHUS. It was approved by the European Medicines Agency for the treatment of PNH on June 20, 2007, and on November 24, 2011 for the treatment of aHUS. Eculizumab is currently being investigated as a potential treatment for other severe, ultra-rare disorders.

Structures of resistance-breaking derivatives of established antibiotic classes. Selected compounds are depicted that were recently launched or are currently in development. Ceftobiprole has increased affinity for PBP2a, a member of the target family of penicillin-binding proteins not affected by marketed β-lactams. Tigecycline, iclaprim, telithromycin, and telavancin make contacts to additional binding sites on their established targets or address additional targets. Structural elements responsible for the novel target interactions are marked bold. MCB-3681, TD-1792, and CBR-2092 are hybrid molecules, in which two pharmacophors from different antibiotic classes are attached by linkers. Linkers are marked bold

All antibiotics that have been successfully employed for decades as monotherapeutics in the treatment of bacterial infections rely on mechanisms of bacterial growth inhibition which are by far more complex than inhibition of a single enzyme. Such successful antibiotics have in common that they address several targets in parallel and/or that their targets are encoded by multiple genes. Such multiplicity of targets and of target genes has the advantage that the emergence of spontaneous target-related resistance is a comparatively slow process. Recently registered antibiotics and novel antibiotics in development are discussed in the light of this promising concept of antibacterial polypharmacology.
