Cystic Fibrosis Statistics

Cystic fibrosis is genetic, driven by CFTR variants on chromosome 7, yet the latest trial evidence makes the contrast startling with ivacaftor cutting pulmonary exacerbations by 55% and raising BMI, while modulators also nudge lung function and sweat chloride in measurable steps. This page also tracks what that progress costs and affects in real care and real markets, from the near universal lung disease rate of 98% to persistent chronic therapy use around 62% at 12 months and major spending pressures in the NHS and US.

Cystic fibrosis is driven by disease-causing variants in the CFTR gene on chromosome 7, yet nearly all people with CF, about 98%, eventually face lung disease in their lifetimes. At the same time, newer therapies have shifted outcomes in measurable ways, from a 55% reduction in pulmonary exacerbations with ivacaftor to meaningful gains in lung function such as FEV1 improvements of several percentage points. This post pulls together the most current statistics on disease progression, treatment impact, and the real-world costs that sit behind those results.
