Pharmacokinetics of Tedizolid Phosphate in Cystic Fibrosis
May 21, 2020 updated by: Paul Beringer, University of Southern California
Steady-State Pharmacokinetics of Tedizolid in Plasma and Sputum of Patients With Cystic Fibrosis
The proposed study is designed to characterize the pharmacokinetics of intravenous and oral tedizolid in patients with Cystic Fibrosis.

Detailed Description
Recent epidemiological studies have demonstrated that the presence of methicillin-resistant Staphylococcus aureus (MRSA) in the airways of patients with CF is associated with more rapid lung function decline and a higher mortality.
Tedizolid is a new antibiotic with potent activity against MRSA.
Tedizolid is currently FDA approved for treatment of skin soft tissue infections with MRSA.
The proposed study is designed to characterize the pharmacokinetics of intravenous and oral tedizolid in patients with CF.

Primary Outcome Measures
Outcome Measure |
Measure Description |
Time Frame |
---|---|---|
Peak Plasma Concentration (Cmax)
Time Frame: 2 days
|
Cmax was calculated using data collected at 0, 0.5, 1, 2, 3, 4, 8, 24, 48 hours post-dose
|
2 days
|
Area Under the Plasma Concentration Versus Time Curve (AUC)
Time Frame: 2 days
|
Area under the curve was calculated using samples collected at baseline (0 h) , 0.5, 1, 2, 3, 4, 8, 24, and 48 hours post-dose and using the equation AUC=Dose*F/CL
|
2 days
|
Time to Peak Plasma Concentration (Tmax)
Time Frame: 2 days
|
Tmax was calculated using data collected at 0, 0.5, 1, 2, 3, 4, 8, 24, 48 hours post-dose
|
2 days
|
Peak Sputum Concentration
Time Frame: 2 days
|
Peak sputum concentration was calculated using data collected at 0, 0.5, 1, 2, 3, 4, 8, 24, 48 hours post-dose.

Area Under the Sputum Concentration Versus Time Curve (AUC)
Time Frame: 2 days
|
AUC was calculated using data collected at 0, 0.5, 1, 2, 3, 4, 8, 24, 48 hours post-dose
|
2 days
|
Time to Peak Sputum Concentration (Tmax)
Time Frame: 2 days
|
Tmax was calculated using data collected at 0, 0.5, 1, 2, 3, 4, 8, 24, 48 hours post-dose.
Tmax was derived from pooled sputum data due to sparse samples and therefore do not have standard deviations.
