VERTEX-PHARMA

Vertex Pharmaceuticals Incorporated (Nasdaq: VRTX) today announced that the European Commission has granted extension of the Marketing Authorization for ORKAMBI^® (lumacaftor/ivacaftor), the first medicine to treat the underlying cause of cystic fibrosis (CF) in people with two copies of the F508del mutation, to include children ages 6 through 11. In Europe, there are approximately 3,400 children ages 6 through 11 with two copies of this mutation. Existing reimbursement agreements in countries such as Ireland will enable rapid access to ORKAMBI for these children. In other countries across the European Union, Vertex will now begin the country-by-country reimbursement process.

“The innovative long-term agreements we have reached in countries like Ireland will enable eligible children to have rapid access to ORKAMBI,” said Simon Bedson, Senior Vice President and International General Manager at Vertex. “Where these agreements are not in place, Vertex is committed to working with local authorities so those who could benefit from this medicine are able to do so as quickly as possible.”

The European Commission’s decision is based on data from two Phase 3 studies of ORKAMBI in children with CF ages 6 through 11 who have two copies of the F508del mutation. In 2017, The Lancet Respiratory published 24-week data from one of these studies, which demonstrated statistically significant improvements in lung function (as assessed by the absolute change in lung clearance index, or LCI_2.5 , and predicted forced expiratory volume in one second, or ppFEV₁ ) among children treated with ORKAMBI compared to placebo. Improvements in body mass index (BMI) and the Cystic Fibrosis Questionnaire-Revised (CFQ-R) respiratory domain score were also observed, although they were not statistically significant. Safety data were similar to those observed in an earlier Phase 3 open-label safety study in children ages 6 through 11. The most common adverse events that occurred more frequently among those receiving ORKAMBI compared to placebo were infective pulmonary exacerbation, productive cough, nasal congestion, oropharyngeal pain, abdominal pain upper, headache, upper respiratory tract infection and sputum increased.

“A principal goal of treating CF is slowing the progressive lung damage caused by this life-shortening genetic disease while improving health in the short term,” said Professor Marcus Mall, M.D., Director of the Division of Pediatric Pulmonology & Allergology and the Cystic Fibrosis Center at the Heidelberg University Hospital, Germany. “Studies of ORKAMBI in children ages 6 through 11 have shown improvements in clinically relevant outcomes, like lung function and weight gain.”

About Cystic Fibrosis (CF)

CF is a rare, life-shortening genetic disease affecting approximately 75,000 people across North America, Europe and Australia.

CF is caused by a defective or missing CFTR protein resulting from mutations in the CFTR gene. Children must inherit two defective CFTR genes — one from each parent — to have CF. There are approximately 2,000 known mutations in the CFTR gene. Some of these mutations, which can be determined by a genetic test, or genotyping test, lead to CF by creating non-working or too few CFTR protein at the cell surface. The defective function or absence of CFTR protein results in poor flow of salt and water into and out of the cell in a number of organs. In the lungs, this leads to the buildup of abnormally thick, sticky mucus that can cause chronic lung infections and progressive lung damage in many patients that eventually leads to death. The median age of death is in the mid-to-late 20s.

About ORKAMBI ^®  (lumacaftor/ivacaftor)

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. Patients with two copies of the F508del mutation are easily identified by a simple genetic test.

ORKAMBI is a combination of lumacaftor, which is designed to increase the amount of mature protein at the cell surface by targeting the processing and trafficking defect of the F508del-CFTR protein, and ivacaftor, which is designed to enhance the function of the CFTR protein once it reaches the cell surface. ORKAMBI is available as tablets and is typically taken twice per day.

Collaborative History with Cystic Fibrosis Foundation Therapeutics, Inc. (CFFT)

Vertex initiated its CF research program in 2000 as part of a collaboration with CFFT, the nonprofit drug discovery and development affiliate of the Cystic Fibrosis Foundation. KALYDECO^®  (ivacaftor), ORKAMBI^® (lumacaftor/ivacaftor), tezacaftor, VX-440, VX-152, VX-659 and VX-445 were discovered by Vertex as part of this collaboration.
