Does a Nasal Instillation of Miglustat Normalize the Nasal Potential Difference in Cystic Fibrosis Patients ?

Cystic Fibrosis Clinical Trial

Official title:
Does a Nasal Instillation of Miglustat Normalize the Nasal Potential Difference in Cystic Fibrosis Patients Homozygous for the F508del Mutation? A Randomized, Double Blind Placebo-controlled Study.

Clinical Trial Summary

The purpose of this study is to investigate within a short delay the effect of nasal instillation of Miglustat on nasal potential difference in cystic fibrosis patients homozygous for the F508del mutation.

Clinical Trial Description

Miglustat is an inhibitor of α-glucosidases and other enzymes. Oral miglustat is currently marketed in Europa and US for the treatment of Gaucher type 1 patients for whom enzyme replacement treatment is not an option.

Gastro-intestinal side effects are common with this formulation. This medication has been shown to have a beneficial effect both on Cl- an Na+ transports in cystic fibrosis epithelial cells. In addition, a single airway delivery of low-dose Miglustat normalizes nasal potential difference (NPD) in F508del cystic fibrosis mice. NPD abnormalities specific of CF patients are considered to reflect the primary defect of CFTR protein so that any curative treatment is expected to correct them at least partially.

In the field of respiratory pharmacology, it is a general rule that the inhaled route is to be favoured whenever possible : it is usually more effective despite much lower doses and systemic absorption (which also implies lower costs and improved tolerance).

The aim of this study is to investigate the effect of a single local administration of Miglustat on NPD measurements in CF patients homozygous for the F508del mutation. ;
