BACKGROUND: Cystic fibrosis (CF) transmembrane conductance regulator modulators improve lung function, however, effects on cough frequency, physical activity, and sleep have not been assessed in clinical studies.
METHODS: After a 12-week, phase 4 pilot feasibility study, we conducted a 13-week, phase 3b, open-label study in participants with CF aged ≥12 years previously naïve to elexacaftor/tezacaftor/ivacaftor (ELX/TEZ/IVA) to assess the effects of ELX/TEZ/IVA on cough frequency, physical activity, and sleep using wearable cough monitors and actigraphy sensors (VX-445-126).
RESULTS: In study VX-445-126 (N = 81), participants treated with ELX/TEZ/IVA experienced a 91.7% reduction in cough frequency (cough events per day) (95% CI, 89.2% to 93.6%; 241.3 coughs per day at baseline to 20.3 coughs per day) from baseline at the average of week 8 through week 12 (primary endpoint). Total steps per day (secondary endpoint) increased by 638 (95% CI, 298 to 977) at the average of week 8 through week 12. Time spent above sedentary physical activity per day, time spent on moderate-to-vigorous physical activity per day, and total mean activity count per day all increased from baseline at the average of week 8 through week 12 (other efficacy endpoints). While no changes in sleep activity patterns were observed in actigraphy data, patient-reported measures of sleep quality improved (other efficacy endpoints). ELX/TEZ/IVA was generally safe and well-tolerated.
CONCLUSIONS: ELX/TEZ/IVA treatment led to a > 90% reduction in daily cough frequency, with sustained improvements in physical activity and better perceptions of sleep quality.
