FDA Orphan Designation for Alexion Drug Candidate

FDA has granted Alexion Pharmaceuticals an orphan drug designation for ALXN1007, a novel anti-inflammatory monoclonal antibody targeting complement protein C5a for treating acute graft-versus-host disease (GVHD). Alexion says it is currently investigating ALXN1007 in patients with acute GVHD in the lower gastrointestinal tract (GI-GVHD), a severe and life-threatening rare autoimmune disease that can occur as a complication of stem cell or bone marrow transplantation. Patients with severe, acute GI-GVHD have a 30% to 40% mortality rate within the first six months post-transplant. A Phase 2 trial is underway in patients with newly diagnosed acute GI-GVHD. More information on this trial is available at www.clinicaltrials.gov under the identifier NCT02245412.
