Ataluren for the treatment of cystic fibrosis.

Alleles causing diseases that carry premature termination codons (PTCs) will cause premature cessation of translation, leading to loss of function and consequent disease. Recently, a novel agent, Ataluren, was developed through a high throughput screening program. Ataluren is orally bioavailable and was shown to be effective in Cystic Fibrosis (CF). Phase I and II studies established the safety and dosing regimens for Ataluren. The results of a short study showed modest improvements in pulmonary function and a reduction in quantitative cough assessment. There was improvement in nasal potential difference and nasal epithelial CFTR protein. In a phase III trial this effect was not observed in patients that were concomitantly treated with tobramycin inhalation. Following these positive findings, a multinational Phase III placebo-controlled efficacy trial is currently underway.
