Trial Outcomes & Findings for Study of LAU-7b in the Treatment of Cystic Fibrosis in Adults (NCT NCT03265288)
NCT ID: NCT03265288
Last Updated: 2024-10-09
Results Overview
Standardized, serial FEV1 measurements were performed during the trial by the clinical sites using standardized spirometers. All spirometry measurements were centrally read and validated by the spirometry provider, Vitalograph. The outcome measure is presented using the Least Squares Mean at the Week 24 time point and the Least Squares Mean of all post-baseline time points through Week 24 averaged.

This was assessed through administration of the Cystic Fibrosis Questionnaire-Revised (CFQ-R) at four planned times during the trial. The CFQ-R respiratory sub-score (range 0-100) was extracted and analyzed. The Minimum Clinically Important Difference (MCID) for the respiratory sub-score is 4 units. A higher score means a better outcome.

Timeframe: From baseline to 28 weeksPopulation: Only very few subjects got sampled pre- and post-pulmonary exacerbation, rendering this data anecdotic. No outcome measure is presented.
Only in patients who experience a pulmonary exacerbation requiring IV antibiotics, this was to be assessed prior to- and after receiving an IV antibiotic course.

OTHER_PRE_SPECIFIED outcome
Timeframe: Baseline and 28 weeksPopulation: Absolute change from Baseline at Week 24. Intent to treat population (ITT) in subjects volunteering to undergo bone density measurement
This was assessed through Lumbar spine bone mineral density measured on 2 occasions during the trial at Baseline and at Week 28 in a subset of sites and on a voluntary basis. Bone mineral density in g/cm2 is then normalized and expressed as a Z-score distribution according to age and gender. A Z-score of 0 represents the population mean for the age and gender category, a -1 value or +1 value means below or above the population mean bone mineral density for the age and gender category, but considered normal. A -2.5 value indicates secondary osteoporosis, a worse outcome.
