FDA approves new breakthrough therapy for cystic fibrosis



The U.S. Food and Drug Administration today approved Trikafta (elexacaftor/ivacaftor/tezacaftor), the first triple combination therapy available to treat patients with the most common cystic fibrosis mutation. Trikafta is approved for patients 12 years and older with cystic fibrosis who have at least one F508del mutation in the cystic fibrosis transmembrane conductance regulator (CFTR) gene, which is estimated to represent 90% of the cystic fibrosis population.

The safety profile of Trikafta is based on data from the 510 cystic fibrosis patients in the two trials. The safety profile was generally similar across all subgroups of patients. Serious adverse drug reactions that occurred more frequently in patients receiving Trikafta compared to placebo were rash and influenza (flu) events. The most common adverse drug reactions included headaches, upper respiratory tract infections, abdominal pains, diarrhea, rashes, increased liver enzymes (alanine aminotransferase and aspartate aminotransferase), nasal congestion, increased blood creatine phosphokinase (an enzyme that can be associated with muscle damage), rhinorrhea (mucus in the nasal cavity), rhinitis (swelling of the mucous membrane of the nose), influenza, sinusitis and increased blood bilirubin (may be caused by problems involving the liver, gallbladder or red blood cells).

The prescribing information for Trikafta includes warnings related to elevated liver function tests (transaminases and bilirubin), use at the same time with other products that are inducers or inhibitors of another liver enzyme called Cytochrome P450 3A4 (CYP3A), and the risk of cataracts. Patients and their caregivers should speak with a health care professional about these risks and any medicines they take before starting treatment.

Patients with cystic fibrosis should speak with a health care professional and have tests performed to understand which gene mutations they have. The presence of at least one F508del mutation should be confirmed using an FDA-cleared genotyping assay prior to treatment. The safety and effectiveness of Trikafta in patients with cystic fibrosis younger than 12 years of age have not been established.
