Eligibility Criteria

18 Years - undefined (Adult, Older Adult)All SexesDoes not accept healthy volunteers

Inclusion Criteria:

Inclusion criteria at screening visit (Visit 1):

  • Homozygous for the F508del mutation as confirmed by genetic testing
  • Sweat chloride ≥ 60 mmol/L
  • Basal nasal potential difference (NPD) ≤ -30.0 mV (equal to or more electrically negative than -30.0 mV) and total chloride secretion (TCS) ≥ - 5.0 mV for at least one nostril. However, if it is possible to analyze both nostrils, the total chloride secretion (TCS) is to be ≥ - 5.0 mV (equal to or more electrically positive than - 5.0 mV) in both nostrils.

5. Study Description

Brief Summary
The purpose of this study is to demonstrate that Miglustat restores the function of the cystic fibrosis transmembrane conductance regulator (CFTR) in adult patients with cystic fibrosis homozygous for the F508del mutation.
Detailed Description
The aims of this study are: To determine whether Miglustat can restore the function of the CFTR protein in adult patients with cystic fibrosis homozygous for the F508del mutation To evaluate the safety, tolerability and pharmacokinetics of Miglustat in adult patients with cystic fibrosis homozygous for the F508del mutation. To investigate pharmacokinetic-pharmacodynamic of Miglustat in adult patients with cystic fibrosis homozygous for the F508del mutation.
