Cystic Fibrosis Clinical Trial
Official title:
A Phase 1, Open-Label, Randomized, Crossover Study to Assess the Safety and Pharmacokinetics Following Single Doses of Oral and Intravenous Xenleta (Lefamulin) in Adult Patients With Cystic Fibrosis
This study is intended to assess the pharmacokinetic (PK) and safety of a single dose of IV and oral formulations of lefamulin in adults with cystic fibrosis (CF).
Staphylococcus aureus is one of the most common causative pathogens associated with exacerbations of CF. Current treatment guidelines for the management of exacerbations of CF caused by S. aureus recommend the use of unapproved antibacterial agents. Further, many of the recommended treatments can only be administered via the IV route and/or have limitations due to safety and tolerability. Lefamulin is a novel, first-in-class, IV and oral pleuromutilin antimicrobial agent that has been demonstrated to be highly potent against S. aureus, including Methicillin-resistant Staphylococcus aureus (MRSA) and strains obtained from patients with CF. Cystic fibrosis patients have altered drug distribution and elimination kinetics for many antimicrobials relative to patients without CF. While the advent of Cystic fibrosis transmembrane conductance regulator (protein) (CFTR) modulators has resulted in improved lung function and had a positive impact on the quality of life of CF patients, limited data have been published describing the impact of the concomitant use of CFTR modulators and commonly used antibacterial agents. ;
