Soliris® in Other Diseases

Alexion's research and development pipeline is now focused on investigating the use of Soliris to block complement-mediated inflammation in patients with other rare and severe conditions, including chronic blood cell and clotting disorders, kidney diseases and transplant rejection, and chronic and debilitating neurological disorders.

This focus is supported by a November 2007 article28 in the journal Nature Biotechnology, which noted that careful, rigorous scientific evaluation similar to that used in the development of Soliris in PNH may be applied to the evaluation of this first-in-class complement inhibitor in patients with other uncommon, debilitating and life-threatening diseases.

In kidney disorders, Alexion is initiating clinical trials to evaluate Soliris for the treatment for patients with atypical Hemolytic Uremic Syndrome, or aHUS, a rare disease that can lead to kidney failure or death. Independent investigators have started a study to evaluate Soliris in patients at high risk for kidney transplant rejection. Independent physicians are also evaluating the use of Soliris in patients with Dense Deposit Disease (DDD).

In hematology, Alexion is planning studies of Soliris in patients with Catastrophic Anti-Phospholipid Syndrome (CAPS) and Cold Agglutinin Disease (CAD), two rare blood cell disorders.

In severe neurologic disorders, the first patients with Myasthenia Gravis, a neuromuscular disease, are now being treated with Soliris in a double-blind placebo-controlled trial. Independent investigators have also started to enroll patients in a study to evaluate Soliris for the treatment of Mutlifocal Motor Neuropathy (MMN).
