Extension Study of Ataluren (PTC124) in Cystic Fibrosis

2014-08-27 03:13:03 | BioPortfolio

Summary

Cystic fibrosis (CF) is a genetic disorder caused by a mutation in the gene that makes the cystic fibrosis transmembrane conductance regulator (CFTR) protein. A specific type of mutation called a nonsense (premature stop codon) mutation is the cause of CF in approximately 10% of subjects with the disease. Ataluren (PTC124) is an orally delivered investigational drug that has the potential to overcome the effects of the nonsense mutation. This study is a Phase 3 extension trial that will evaluate the long-term safety of ataluren (PTC124) in adult and pediatric patients with nonsense mutation CF, as determined by adverse events and laboratory abnormalities. The study will also assess changes in pulmonary function, CF pulmonary exacerbations, health-related quality of life, antibiotic use for CF-related infections, CF-related disruptions to daily living, body weight, and CF pathophysiology.

Description

This Phase 3, open-label, safety and efficacy study will be performed at sites in North America, Europe, and Israel. The study will enroll up to approximately 208 patients with nonsense mutation CF who participated in a previous Phase 3 study of ataluren (PTC124) (PTC124-GD-009-CF, NCT00803205). Subjects will receive study drug 3 times per day (at breakfast, lunch, and dinner) for approximately 48 weeks (approximately 1 year). Study assessments will be performed at clinic visits every 8 weeks.

Medical and Biotech [MESH] Definitions

An autosomal recessive genetic disease of the EXOCRINE GLANDS. It is caused by mutations in the gene encoding the CYSTIC FIBROSIS TRANSMEMBRANE CONDUCTANCE REGULATOR expressed in several organs including the LUNG, the PANCREAS, the BILIARY SYSTEM, and the SWEAT GLANDS. Cystic fibrosis is characterized by epithelial secretory dysfunction associated with ductal obstruction resulting in AIRWAY OBSTRUCTION; chronic RESPIRATORY INFECTIONS; PANCREATIC INSUFFICIENCY; maldigestion; salt depletion; and HEAT PROSTRATION.

A chloride channel that regulates secretion in many exocrine tissues. Abnormalities in the CFTR gene have been shown to cause cystic fibrosis. (Hum Genet 1994;93(4):364-8)

A strain of mice widely studied as a model for cystic fibrosis. These mice are generated from embryonic stem cells in which the CFTR (cystic fibrosis transmembrane conductance regulator) gene is inactivated by gene targeting. As a result, all mice have one copy of this altered gene in all their tissues. Mice homozygous for the disrupted gene exhibit many features common to young cystic fibrosis patients, including failure to thrive, meconium ileus, and alteration of mucous and serous glands.

A species of STENOTROPHOMONAS, formerly called Xanthomonas maltophilia, which reduces nitrate. It is a cause of hospital-acquired ocular and lung infections, especially in those patients with cystic fibrosis and those who are immunosuppressed.

A rehabilitation therapy for removal of copious mucus secretion from the lung of patients with diseases such as CHRONIC BRONCHITIS; BRONCHIECTASIS; PULMONARY ABSCESS; or CYSTIC FIBROSIS. The patient's head is placed in a downward incline (so the TRACHEA is inferior to the affected area) for 15- to 20-minute sessions.
