Vertex Announces Reimbursement Agreement in Australia for TRIKAFTA ® (elexacaftor/tezacaftor/ivacaftor and ivacaftor) for Patients With Cystic Fibrosis Ages 12 Years and Older With at Least One F508del Mutation in the CFTR Gene

Vertex Pharmaceuticals Incorporated (Nasdaq: VRTX) today announced that as of 1 April 2022, TRIKAFTA^® (elexacaftor/tezacaftor/ivacaftor and ivacaftor) will be reimbursed on the Australian Pharmaceutical Benefits Scheme (PBS) for the treatment of cystic fibrosis (CF) in people ages 12 years and older who have at least one F508del mutation in the CFTR gene, the most common CF-causing mutation worldwide.

“Today’s announcement is a significant milestone in ensuring Australians living with CF receive timely and sustainable access to TRIKAFTA,” said Ludovic Fenaux, Senior Vice President, Vertex International. “This is the fourth treatment we have brought to Australians over the last eight years, working tirelessly alongside the CF patient and clinical communities. We thank the Australian Government for recognizing the significant need for TRIKAFTA and the value it brings.”

TRIKAFTA^® (elexacaftor/tezacaftor/ivacaftor and ivacaftor) was approved by the Australian Therapeutic Goods Administration (TGA) in March 2021 based on the results of four global Phase 3 clinical trials, which included multiple Australian trial sites and patients.

CF is a rare, life-shortening, genetic disease affecting approximately 3,500 people in Australia. It is caused by a defective and/or missing CFTRprotein, resulting from mutations in the CFTR gene.Up to 90 percent of people living with CF have at least one F508del mutation.

“As a genetic disease, cystic fibrosis is a prime candidate for precision medicine. Now, with PBS listing of TRIKAFTA, eligible Australians living with CF ages 12 years and older can broadly access a therapy that treats the underlying cause of their disease. Clinicians across Australia will be excited about this most welcome news,” said Professor John Wilson AM, Head, Cystic Fibrosis Service, Alfred Health Australia.

Australia now joins the list of 30 countries where the triple combination therapy is approved and reimbursed including Denmark, Finland, France, Germany, Italy, Ireland, Israel, Poland, Spain, Switzerland and the countries within the U.K.

About Cystic Fibrosis

Cystic fibrosis (CF) is a rare, life-shortening genetic disease affecting more than 83,000 people globally. CF is a progressive, multi-organ disease that affects the lungs, liver, pancreas, GI tract, sinuses, sweat glands and reproductive tract. CF is caused by a defective and/or missing CFTR protein resulting from certain mutations in the CFTR gene. Children must inherit two defective CFTR genes — one from each parent — to have CF, and these mutations can be identified by a genetic test. While there are many different types of CFTR mutations that can cause the disease, the vast majority of people with CF have at least one F508del mutation. CFTR mutations lead to CF by causing the CFTR protein to be defective or by leading to a shortage or absence of CFTR protein at the cell surface. The defective function and/or absence of CFTR protein results in poor flow of salt and water into and out of the cells in a number of organs. In the lungs, this leads to the buildup of abnormally thick, sticky mucus, chronic lung infections and progressive lung damage that eventually leads to death for many patients. The median age of death is in the early 30s.

About TRIKAFTA^® (elexacaftor/tezacaftor/ivacaftor and ivacaftor)

In people with certain types of mutations in the CFTR gene, the CFTR protein is not processed or folded normally within the cell, and this can prevent the CFTR protein from reaching the cell surface and functioning properly. TRIKAFTA^® (elexacaftor/tezacaftor/ivacaftor and ivacaftor) is an oral medicine designed to increase the quantity and function of the CFTR protein at the cell surface. Elexacaftor and tezacaftor work together to increase the amount of mature protein at the cell surface by binding to different sites on the CFTR protein. Ivacaftor, which is known as a CFTR potentiator, is designed to facilitate the ability of CFTR proteins to transport salt and water across the cell membrane. The combined actions of elexacaftor, tezacaftor and ivacaftor help hydrate and clear mucus from the airways.
