  • Ages 18 years and older
  • All sexes
  • No healthy volunteers

Who cannot join

  • Females that are pregnant and/or breastfeeding

About this study

Official title: Population Pharmacokinetics of Cefiderocol During Acute Pulmonary Exacerbations in Adult Patients With Cystic Fibrosis

There is established evidence that adult patients with Cystic Fibrosis (CF) may have altered antibiotic pharmacokinetics compared with non-CF patients. Cefiderocol is a newly approved broad spectrum intravenous siderophore cephalosporin antibiotic, which has potent in vitro activity against multidrug resistant Pseudomonas aeruginosa, Burkholderia cepacia complex, Achromobacter species, and Stenotrophomonas maltophilia, all pathogens implicated in CF pulmonary exacerbations. This study will determine the pharmacokinetics and tolerability of cefiderocol in 12 adult CF patients admitted for a pulmonary exacerbation at one of 4 participating hospitals in the US. Patients will remain on standard of care IV antibiotics and receive 4-6 doses of cefiderocol 2 grams infused over 3 hours every 6-8 hours, depending on kidney function. Blood will be sampled after the final dose to determine concentrations and pharmacokinetics of cefiderocol. Safety and tolerability will be assessed throughout the 2 day study.

Read the detailed description

Participants will receive 4-6 doses of cefiderocol 2 grams every 6-8 hours, in addition to standard intravenous antibiotic therapy selected by the site. Just prior and then after the final dose, a total of nine blood samples will be collected to measure cefiderocol concentrations. Data will be fit to a population pharmacokinetic model. The final model will be utilized in a Monte Carlo simulation to determine the probability of several different dosing regimens retaining concentrations above the minimum inhibitory concentration (MIC) for at least 75% of the dosing interval. These data will be utilized to determine an optimized dosing regimen for adults with CF.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Clearance

    This outcome determines the clearance of cefiderocol over the dosing interval.

    Measured: 0, 1.5, 3, 3.25, 4, 5, 6, and 8 hours after the final dose

  2. Volume of Distribution

    This outcome determines the volume of distribution of cefiderocol over the dosing interval.

    Measured: 0, 1.5, 3, 3.25, 4, 5, 6, and 8 hours after the final dose

Secondary outcomes (1)
  1. Probability of Target Attainment at 4 mcg/mL

    This simulated outcome indicates the likelihood that cefiderocol will retain drug concentrations above the MIC for >/= 75% of the dosing interval at an MIC of 4 mcg/ml when administered as a 2g every 8 hour dose infused over 3 hour in patients up to a creatinine clearance of 120 ml/min. This analysis is conducted via a Monte Carlo simulation using the population pharmacokinetic parameter estimates and dispersion from the 12 participants who contributed pharmacokinetic data to the study

    Measured: 24 hours

Questions about this trial

What is this clinical trial studying?

A Phase 4 study testing Cefiderocol in people with Cystic Fibrosis and Pneumonia, Bacterial, run by Hartford Hospital at 4 sites in United States.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 2 inclusion and 6 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: finished, as of the sponsor's last update on 16 Dec 2024. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 4 sites in United States. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

What does this phase mean?

Phase 4 studies take place after a treatment is approved, to learn more about its long-term benefits and risks in everyday use.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

Are results available for this study?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Clearance (time frame: 0, 1.5, 3, 3.25, 4, 5, 6, and 8 hours after the final dose). The study lists 2 primary outcomes in all. It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 16 Dec 2024.
