1 A Phase 2a, Randomized, Double-Blind, Placebo-Controlled Study of VX-770 to Evaluate Safety, Pharmacokinetics, and Biomarkers of CFTR Activity in Cystic Fibrosis (CF) Subjects With Genotype G551D

The purpose of this study was to evaluate the safety and tolerability of ivacaftor in patients with cystic fibrosis (CF) who were aged 18 years or older and have a G551D mutation in the cystic fibrosis transmembrane conductance regulator (CFTR) gene. Ivacaftor is a potent and selective CFTR potentiator of wild-type, G551D, F508del, and R117H forms of human CFTR protein. Potentiators are pharmacological agents that increase the chloride ion transport properties of the channel in the presence of cyclic AMP-dependent protein kinase A (PKA) activation.

5 A Phase 2, Single-Blind, Placebo-Controlled Study to Evaluate the Effect of VX-770 on Hyperpolarized Helium-3 Magnetic Resonance Imaging in Subjects With Cystic Fibrosis, the G551D Mutation, and FEV1 ≥40% Predicted

Cystic Fibrosis (CF) is caused by mutations in the cystic fibrosis transmembrane conductance regulator (CFTR) gene. The encoded protein, CFTR, is an epithelial chloride ion channel responsible for aiding in the regulation of salt and water absorption and secretion in various tissues. Although the disease affects multiple organs, the leading cause of mortality is the progressive loss of lung function. Obstruction of airways with thick mucus, chronic bacterial infection of the airways, and inflammatory response are all thought to play a role in causing lung damage. Through its function as a chloride channel, CFTR is believed to be integral in epithelial ion and water transport and hence, maintaining the normal hydration of lung secretions. VX-770 (ivacaftor) is a potent and selective potentiator of wild-type, G551D, F508del, and R117H forms of human CFTR. Based on in vitro studies and pharmacologic, pharmacokinetic (PK), and safety profiles, VX-770 has been selected for clinical development as a possible treatment for patients with CF. Hyperpolarized noble gas magnetic resonance imaging (HG-MRI) is a promising new means of assessing lung function by direct imaging of certain non-radioactive isotopes of an inert noble gas, such as helium or xenon. Through this technique, high-resolution 3-dimensional images of lung ventilation can be obtained in both pediatric and adult patients during a single short breath-hold following inhalation of the gas. This is a 2-part study to evaluate the effect of VX-770 on hyperpolarized helium-3 magnetic resonance imaging (3He-MRI), and to evaluate the safety and efficacy of VX-770 in subjects aged 12 years and older with CF who have the G551D-CFTR mutation. Part A is a single-blind, placebo-controlled study that includes 4 weeks of VX-770 treatment and 4 weeks of placebo treatment. Part B is an open-label, 48 week study of long-term effect of VX 770 on hyperpolarized 3He-MRI.

11 Prospective Study of the Phenotypic Expression of Cystic Fibrosis (CF) Screened Positive Newborns With an Atypical Form of CF (DPAM)

The strategy of neonatal screening for Cystic Fibrosis in France relies on Immuno Reactive Trypsinogen (IRT) at day 3/DNA analysis with a CF Elucigen 30 mutations kit/ IRT safety-net at day 21. This strategy has significantly improved the performance of CF neonatal screening (NNS) in terms of positive predictive value and sensitivity but revealed new difficulties. Up to 85-90% of CF patients detected through the NNS program has a classical CF form with a positive sweat test and 2, 1 or no CF causing mutations but the remainder has either 2 CFTR mutations with at least one non-CF causing mutation and a sweat test <60mmol/L or 1, 0 CFTR mutation and an intermediate sweat test value ≥ 30 et < 60mmol/L raising a diagnosis and prognosis dilemma. Meanwhile the vast majority of these cohorts will remain asymptomatic over time, some will develop symptoms prompting clinicians to maintain a rigorous surveillance for the entire atypical cohort, whose modalities vary a lot among centers and countries. This prospective multicenter study with a standardized assessment of a matched cohort with "atypical" CF versus "classical" CF from 6 years of age (60-65 cases in each cohort) is aimed at evaluating pulmonary and nutritional status to, better define the best monitoring follow-up, therapeutic management and familial genetic counseling.

16 Response to CFTR-modulators in Intestinal Organoids of Patients With CF Having at Least One R334W Mutation

In contrary to what is seen in FRT cells, rectal organoids of patients with a R334W mutation do respond to CFTR modulators ivacaftor and lumacaftor. The present study will investigate the response to modulators in organoids of 30 patients with CF and a R334W mutation, to allow further stratificaton for a future clinical trial assessing the clinical effect of ivacaftor/tezacaftor in patients with CF and a R334W mutation.
