Révolution dans le traitement de la mucoviscidose [Revolution in the treatment of cystic fibrosis]

Abstract

Cystic Fibrosis is a genetic disorder resulting in the absence or dysfunction of the CFTR protein, a chloride channel present on the surface of epithelia, particularly respiratory. Until recently, treatments only concerned the consequences of the disease. But a new type of molecules called « modulators », is already available to some patients and targets the origin of the disease. « Modulators » are divided into « potentiators », which improve the transport of chloride by the CFTR protein, and « correctors », increasing the amount of CFTR proteins. An oral triple therapy combining a potentiator and two correctors has just been approved in the USA and will treat 85 % of patients. The clinical benefit of « modulators » is remarkable, and these drugs are revolutionizing the treatment of Cystic Fibrosis
