Official title
A Multicenter, Open-label Study to Determine the Pharmacokinetics, Safety, and Outcomes of Imipenem/Cilastatin/Relebactam During Treatment of Acute Pulmonary Exacerbations in Adolescent and Adult Patients With Cystic Fibrosis
Brief summary
Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.
There is established evidence that patients with Cystic Fibrosis (CF) may have altered antibiotic pharmacokinetics compared with non-CF patients. Imipenem/cilastatin/relebactam is a novel broad spectrum intravenous beta-lactam/beta-lactamase inhibitor combination antibiotic with potent activity against multidrug resistant Gram-negative bacteria, including imipenem non-susceptible Pseudomonas aeruginosa. Relebactam has also been shown to restore imipenem activity in Burkholderia cepacia complex, a group of opportunistic multidrug resistant pathogens that commonly infect patients with CF. This study will determine the pharmacokinetics and tolerability of imipenem/cilastatin/relebactam in 16 adolescent and adult patients with CF acute pulmonary exacerbations at one of seven participating hospitals in the US, with exploratory aim of reporting relative percent increase in FEV1 from pre- to post-treatment and return to baseline FEV1 after treatment with imipenem/cilastatin/relebactam for acute pulmonary exacerbations due to P. aeruginosa in patients with CF. Patients will receive a 10-14 day course of imipenem/cilastatin/relebactam, dosed according to renal function every 6 hours over 30 mins, with or without adjunctive aminoglycoside or fluoroquinolone therapy per local hospital guidelines. Blood will be sampled during one dosing interval at steady-state (i.e. after at least 3 doses) to determine concentrations and pharmacokinetics of imipenem and relebactam. Relative change in pulmonary function will be assessed two weeks after end of therapy. Safety and tolerability will be assessed throughout the duration of the study.
