GENEVA, Switzerland – July 27, 2012−
Vertex Pharmaceuticals Incorporated (Nasdaq:VRTX) announced today that the European Commission has approved
KALYDECO TM (ivacaftor) for people with cystic fibrosis (CF) ages 6 and older who have at least one copy of the
G551D mutation in the cystic fibrosis transmembrane conductance regulator (CFTR) gene.
KALYDECO is the first medicine to target the underlying cause of the disease in these patients.
Cystic fibrosis is a rare genetic disease caused by defective or missing CFTR proteins resulting
from mutations in the CFTR gene. In people with the G551D mutation, KALYDECO helps the
defective CFTR protein function more normally. An estimated 1,100 people in Europe have the
G551D mutation. The approval of KALYDECO comes two months after the European
Committee for Medicinal Products for Human Use (CHMP) issued a positive opinion and is the
first European approval for Vertex.
“The European approval of KALYDECO is an important step in our commitment to bring
transformative new medicines to people with cystic fibrosis,” said Jeffrey Leiden, M.D., Ph.D.,
Vertex’s Chair, President and Chief Executive Officer. “We’re preparing to supply pharmacies
throughout Europe with KALYDECO and are working closely with national health authorities to
make it available to patients as quickly as possible.”
The European Commission’s decision is based on positive findings from two global Phase 3
studies in which KALYDECO demonstrated significant and sustained improvements in
breathing, weight gain and other measures of disease for people ages 6 and older with this
specific genetic mutation, compared to placebo. In addition, people who took KALYDECO were
55 percent less likely to have pulmonary exacerbations, or periods of worsening in the signs and
symptoms of the disease that often require treatment with antibiotics and hospital visits, than
those who received placebo.
Fewer people in the KALYDECO treatment groups discontinued treatment due to adverse events
than in the placebo groups. The majority of the adverse events associated with KALYDECO
were mild to moderate. Adverse reactions very commonly observed in those taking
KALYDECO (>1/10) included headache; upper respiratory tract infection (common cold)
including sore throat and nasal congestion; rash; diarrhoea; and abdominal pain (stomach ache).
Two patients in the group receiving KALYDECO reported a serious adverse reaction of
abdominal pain.
“Cystic fibrosis is a life-threatening genetic disease that causes devastating effects, particularly
in the lungs, including the build up of thick, sticky mucus which becomes infected and severely
limits normal breathing,” said Stuart Elborn, M.D., KALYDECO investigator and President of
the European Cystic Fibrosis Society. “KALYDECO is one of the most important advances in
the treatment of cystic fibrosis since the discovery of the CF gene in 1989. By treating the
underlying cause of the disease in people with the G551D mutation, KALYDECO helped them
breathe more easily, gain weight and resulted in certain improvements in quality of life.”
“KALYDECO is an exciting new beginning in the treatment of cystic fibrosis, but we’re not
finished,” said Peter Mueller, Ph.D., Chief Scientific Officer and Executive Vice President of
Global Research and Development at Vertex. “The scientists at Vertex, in collaboration with
doctors, patients and advocates around the world, are working hard to develop additional new
medicines to treat the underlying cause of the disease in many more people with cystic fibrosis.”
KALYDECO was discovered as part of a collaboration with Cystic Fibrosis Foundation
Therapeutics, Inc., the nonprofit drug discovery and development affiliate of the Cystic Fibrosis
Foundation.
About KALYDECO
KALYDECO™ (ivacaftor) is the first treatment to target the underlying cause of CF in people
with the G551D mutation in the CFTR gene. Known as a CFTR potentiator, KALYDECO is an
oral medicine that aims to help the CFTR protein function more normally once it reaches the cell
surface, to help hydrate and clear mucus from the airways. KALYDECO (150mg, q12h) was
first approved by the U.S. Food and Drug Administration in January 2012, for use in people with
CF ages 6 and older who have at least one copy of the G551D mutation in the
CFTR gene. Vertex retains worldwide rights to develop and commercialize KALYDECO. KALYDECO is
under Priority Review by the Therapeutic Product Directorate (TPD) of Health Canada, and an
application for review has been submitted to the Therapeutic Goods Administration (TGA) of
Australia.
