The Food and Drug Administration announced on Monday (October 21)—months ahead of its expected decision date—that it has approved a new treatment for cystic fibrosis. Trikafta, made by Vertex Pharmaceuticals, is, as its name suggests, a combination of three drugs. It works for 90 percent of patients with cystic fibrosis, and will be priced at $311,000 per year.

Trikafta is a “transformative medication which is going to significantly improve outcomes for people with cystic fibrosis,” Mike Boyle, senior vice president of therapeutics development at the Cystic Fibrosis Foundation, which funded early research toward the drug, tells STAT.

The outlet notes that Trikafta was developed unusually quickly, in part because Vertex opted to test several different three-drug combinations simultaneously (the company already had one-drug and two-drug cystic fibrosis treatments on the market). In trials, the drug increased the amount of air that patients could exhale in one second by 14 percent.
