상세 설명

Cystic fibrosis (CF) is a genetic disorder caused by mutations in the gene encoding the cystic fibrosis transmembrane conductance regulator (CFTR) protein. Over 1,900 mutations, categorized into five genotypic or functional classes are implicated in causing CF. Severity of disease varies widely in CF based on CFTR-dependent and independent factors. Progressive obstructive lung disease is the main determinant of morbidity and mortality in CF; therefore it is critical to identify biomarker profiles that reflect and predict this phenotypic variability, and understand their relationship to residual CFTR activity. Emerging CFTR modulator therapies that directly target defective CFTR are being evaluated in pivotal clinical trials and may become available in the next few years. It is not known how partial restoration of CFTR function might impact CF disease progression and disease-related biomarkers. Thus there is urgent need to i) identify and validate biomarkers that might reflect partial restoration of CFTR function and can be used to monitor disease progression, and ii) evaluate the mechanistic effects of CFTR modulators and other relevant therapies in individuals with CF

측정값 설명
기간
Sweat Chloride by Cohort (Part A Only)
기간: For cohort 1, sweat chloride at Day 0 is time frame. For cohorts 2-3, sweat chloride averaged across all 3 visits at days 0, 14 and 90 is time frame.

This is the primary endpoint for Part A per the PROSPECT protocol. Mean sweat chloride was not reported for Part B, as it is not a relevant statistic.

For cohort 1, sweat chloride is from day 0 only. For cohorts 2-3, sweat chloride was averaged from days 0, 14, 90 via a random intercept longitudinal model.
For cohort 1, sweat chloride at Day 0 is time frame. For cohorts 2-3, sweat chloride averaged across all 3 visits at days 0, 14 and 90 is time frame.
6 Month Change in FEV1 Percent Predicted (Part B Only)
기간: Baseline and 6 months
This is the primary endpoint for Part B per the PROSPECT protocol. Change in FEV1 Percent Predicted is only relevant for Part B as it captures changes in lung function post-initiation of Ivacaftor/Lumacaftor.
