Vertex Confirms Wales Offer Accepted for Access to All Licensed Cystic Fibrosis Medicines

Vertex Pharmaceuticals Incorporated (Nasdaq: VRTX) today confirms that NHS Wales has accepted an offer for all currently licensed Vertex cystic fibrosis (CF) medicines and any future indications of these medicines under the same terms as the recently announced agreement with NHS England.

This means that once the contract is finalized, patients with CF in Wales ages 2 years and older who have two copies of the F508del mutation in the cystic fibrosis transmembrane conductance regulator (CFTR) gene can access ORKAMBI ^® (lumacaftor/ivacaftor) and CF patients ages 12 years and older who either have two copies of the F508del mutation or one copy of the F508del mutation and a copy of one of the other 14 licensed mutations can access SYMKEVI^® (tezacaftor/ivacaftor) in combination with ivacaftor in the coming weeks.

The agreement also offers expanded access to KALYDECO ^® (ivacaftor) to include those patients ages 12 months and older who have one of the nine licensed gating mutations.

“Today’s announcement is good news for the approximately 270 eligible cystic fibrosis patients in Wales who will soon have access to CFTR modulators to treat the underlying cause of their disease,” said Ludovic Fenaux, Senior Vice President, Vertex International. “We thank the authorities in Wales for their collaboration in accepting this offer under the same terms as were recently announced in England.”

About CF in the UK
Over 10,000 people in the UK have CF — the second highest number in the world. Over 430 people in Wales have CF. CF is a debilitating, life-shortening inherited condition that causes progressive damage to organs across the body from birth. Currently, there is no cure for CF and half of people in the UK with CF die before they are 32. The daily impact of treatment is significant. It can take up to four or more hours, involving nebulizers, physiotherapy and up to 70 tablets a day. CF accounts for 9,500 hospital admissions and over 100,000 hospital bed days a year. A third of these are used by children under 15.

About ORKAMBI^® (lumacaftor/ivacaftor) and the F508del mutation
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.

Lumacaftor/ivacaftor 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.

About SYMKEVI^® (tezacaftor/ivacaftor) in combination with ivacaftor
Some mutations result in CFTR protein that is not processed or folded normally within the cell, and that generally does not reach the cell surface. Tezacaftor is designed to address the trafficking and processing defect of the CFTR protein to enable it to reach the cell surface and ivacaftor is designed to enhance the function of the CFTR protein once it reaches the cell surface.

SYMKEVI is indicated for people with CF ages 12 and older who either have two copies of the F508del mutation or one copy of the F508del mutation and have one of the following 14 mutations in which the CFTR protein shows residual function: P67L, R117C, L206W, R352Q, A455E, D579G, 711+3A→G, S945L, S977F, R1070W, D1152H, 2789+5G→A, 3272-26A→G, or 3849+10kbC→T.

About KALYDECO^® (ivacaftor)
KALYDECO^® (ivacaftor) is the first medicine to treat the underlying cause of CF in people with specific mutations in the CFTR gene. Known as a CFTR potentiator, ivacaftor is an oral medicine designed to keep CFTR proteins at the cell surface open longer to improve the transport of salt and water across the cell membrane, which helps hydrate and clear mucus from the airways.

KALYDECO is indicated in people ages 12 months and older who have one of the following mutations in the CFTR gene: G551D, G1244E, G1349D, G178R, G551S, S1251N, S1255P, S549N or S549R. KALYDECO is also indicated for the treatment of patients with CF ages 18 years and older who have an R117H mutation in the CFTR gene.
