FDA decision expected by July 5, 2015 PDUFA date
Approximately 8,500 people with cystic fibrosis in the U.S. have two copies of the F508del mutation and are ages 12 and
older
BOSTON–(BUSINESS WIRE)– Vertex Pharmaceuticals Incorporated (Nasdaq: VRTX) today announced that the U.S. Food and Drug Administration’s (FDA) Pulmonary-Allergy Drugs Advisory Committee (PADAC) voted 12 to 1 to recommend that the FDA approve ORKAMBITM (lumacaftor/ivacaftor) for use in people with cystic fibrosis (CF) ages 12 and older who have two copies of the F508del mutation in the CFTR gene. Advisory committees provide the FDA with independent scientific and medical advice on safety, effectiveness and appropriate use of potential new medicines. The FDA is expected to make a decision on the approval of ORKAMBI by July 5, 2015 under the Prescription Drug User Fee Act (PDUFA). The FDA is not bound by the committee’s recommendation but often follows its advice. If approved, ORKAMBI will be the first and only medicine to treat the underlying cause of CF for eligible people with CF ages 12 and older with two copies of the F508del mutation in the CFTR gene. People with two copies of the F508del mutation represent the largest group of people with CF. There are approximately 8,500 people ages 12 and older with two copies of the F508del mutation in the U.S.
“Today’s positive recommendation brings the cystic fibrosis community one step closer to potential approval of the first medicine to treat the underlying cause of this disease for many more people,” said Jeffrey Chodakewitz, M.D., Executive Vice President and Chief Medical Officer at Vertex. “We look forward to continuing to work with the FDA and other regulatory agencies throughout the world to make ORKAMBI available to eligible patients as soon as possible.”
Cystic fibrosis is a rare genetic disease that is caused by defective or missing CFTR proteins resulting from mutations in the CFTR gene. The defective or missing proteins result in poor flow of salt and water into and out of the cell in a number of organs, including the lungs. In people with two copies of the F508del mutation, the CFTR protein is not processed and
trafficked normally within the cell, resulting in little to no CFTR protein at the cell surface.
ORKAMBI is a combination of lumacaftor, which is designed to increase the amount of functional protein at the cell surface by addressing the processing and trafficking defect of the protein, and ivacaftor, which is designed to enhance the function of the CFTR protein once it reaches the cell surface. ORKAMBI is an oral medicine that, if approved, would be taken as fully coformulated tablets that contain both lumacaftor and ivacaftor.
