Cystic fibrosis is a distressing disease, clogging the lungs of children who have to fight to breathe, and shortening lives. Parents - and young adults who also suffer from it - have been on a rollercoaster ride in the last few years. They have been taken to the giddy heights of hope by the invention of drugs that for the first time work on the underlying causes of the illness where previous treatment just alleviated symptoms.

Then came Orkambi in 2015 and Symkevi in 2018 - both two-drug combinations. Since 2020, there has been Kaftrio, which is a triple combination. Hopes rose in the UK as the combination drugs were shown to target more genetic mutations and help more people, only to be dashed by the verdict of the cost-effectiveness watchdog body, the National Institute for Health and Care Excellence (Nice).
