Vertex Announces US FDA Approval for Label Extensions of ALYFTREK ® and TRIKAFTA ®, Expanding Availability of These Medicines to ~95% of All People With CF in the United States
BOSTON--( BUSINESS WIRE)-- Vertex Pharmaceuticals Incorporated (Nasdaq: VRTX) today announced the U.S. Food and Drug Administration (FDA) has approved expanded use of ALYFTREK ® (vanzacaftor/tezacaftor/ivacaftor) for the treatment of people with cystic fibrosis (CF) ages 6 and older with a variant in the cystic fibrosis transmembrane conductance regulator (CFTR) gene that is either responsive based on clinical and/or in vitro data or results in production of CFTR protein. Additionally, the U.S. FDA has also expanded the indication statement for TRIKAFTA ® (elexacaftor/tezacaftor/ivacaftor and ivacaftor) in patients ages 2 and older.
This label expansion was supported by clinical and/or in vitro data from 564 variants demonstrating response to ALYFTREK and 521 variants demonstrating response to TRIKAFTA. As such, approximately 800 more people with a clinical diagnosis of CF in the U.S. are now eligible for a medicine that treats the underlying cause of their disease for the first time. This extension means approximately 95% of people with CF in the U.S. are now eligible for treatment with a CFTR modulator.
“This groundbreaking approval represents more than 20 years of innovation in CF, including testing over 600 variants in our laboratory, demonstrating clinical effects in large clinical trials, and studying younger people with CF so they can be treated as early as possible,” said Carmen Bozic, M.D., Executive Vice President, Global Medicines Development and Medical Affairs, and Chief Medical Officer at Vertex. “With this label expansion, any variant that results in production of CFTR protein is now included in the ALYFTREK and TRIKAFTA labels, validating that these medicines can restore CFTR function and provide clinical benefit to patients regardless of where in the CFTR protein a variant is located. We thank the CF community and investigators for their trust and look forward to bringing ALYFTREK and TRIKAFTA to more patients than ever before.”

IMPORTANT SAFETY INFORMATION
WARNING: DRUG-INDUCED LIVER INJURY AND LIVER FAILURE
Elevated transaminases have been observed in patients treated with ALYFTREK.
TRIKAFTA can cause serious and potentially fatal drug-induced liver injury. Cases of liver failure leading to transplantation and death have been reported in both clinical trials and the postmarketing setting in patients with and without a history of liver disease taking TRIKAFTA, a fixed-dose combination drug containing elexacaftor (ELX), tezacaftor (TEZ), and ivacaftor (IVA), the same or similar active ingredients as ALYFTREK. Liver injury has been reported within the first month of therapy and up to 15 months following initiation of TRIKAFTA.
Assess liver function tests (ALT, AST, alkaline phosphatase, and bilirubin) in all patients prior to initiating ALYFTREK or TRIKAFTA, then every month during the first 6 months of treatment, every 3 months for the next 12 months, and at least annually thereafter. Consider more frequent monitoring for patients with a history of liver disease or liver function test (LFT) elevations at baseline.
Interrupt ALYFTREK or TRIKAFTA for significant elevations in LFTs or in the event of signs or symptoms of liver injury. Consider referral to a hepatologist. Follow patients closely with clinical and laboratory monitoring until abnormalities resolve. If resolved, resume treatment only if benefit is expected to outweigh risk. Closer monitoring is advised after resuming treatment.
ALYFTREK or TRIKAFTA should not be used in patients with severe hepatic impairment (Child-Pugh Class C). ALYFTREK or TRIKAFTA is not recommended in patients with moderate hepatic impairment (Child-Pugh Class B). ALYFTREK or TRIKAFTA should only be considered when there is a clear medical need and benefit outweighs risk. If ALYFTREK is used, monitor patients closely. If TRIKAFTA is used, use with caution at a reduced dosage and monitor patients closely.

About Cystic Fibrosis
Cystic fibrosis (CF) is a rare, life-shortening genetic disease affecting more than 112,000 people, including approximately 97,000 people in the United States, Europe, Australia and Canada. 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 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 30s, but with treatment, projected survival is improving.

Today Vertex CF medicines are treating over 75,000 people with CF across more than 60 countries on six continents. This represents approximately 2/3 of the diagnosed people with CF eligible for CFTR modulator therapy.
