Cystic Fibrosis Clinical Trial
Official title:
A Double Blind, Cross-Over Study Comparing Aerosolized Lucinactant and Vehicle on Mucociliary Clearance for Cystic Fibrosis Lung Disease
Mucus clearance is impaired in cystic fibrosis. Inhaled surfactants may reduce adhesive forces between mucus and airway surfaces and improve mucus clearance. This in turn my improve lung health. The investigators propose to measure mucus clearance before and after lucinactant or vehicle administration in patients with cystic fibrosis.
This single-center pilot study is designed as a double-blind, randomized, cross-over clinical trial to evaluate the effects of inhaled lucinactant, an investigational peptide-containing synthetic surfactant (6 ml of 20 mg total phospholipid (TPL)/mL solution x 5 doses) in patients with mild to moderate CF lung disease. Lucinactant and vehicle will be delivered via a 510k approved vibrating mesh nebulizer, the Pari eFlowTM. The study duration corresponds to a 2-10 day screening phase, followed by a 20 day post-randomization phase that consists of two treatment periods (3 days each) and a washout period (14 days). A total of 16 patients will be enrolled and randomly assigned to one of two treatment sequences (Lucinactant followed by vehicle or vehicle followed by lucinactant). The primary outcome will be the rate of MC, as assessed via gamma scintigraphy, post-lucinactant and post vehicle. Secondary outcomes will include the rate of cough clearance (CC), lung clearance index (LCI), absolute change from baseline in FEV1 after 5 doses of study medication, CF-specific quality of life score (via CFQ-R instrument), in vitro assessments of sputum rheology, and various safety parameters. ;
