About this study

Official title: Colistin Pharmacokinetics in Critically Ill Patients With Acute Kidney Injury AKIN III During Extended Dialysis Using the GENIUS Dialysis System

The emergence of multidrug-resistant bacteria has recently renewed interest in colistin. Data on dosing in critically ill patients undergoing extended dialysis are missing. The aim of this study is to determine the pharmacokinetics of colistin during extended dialysis in critically ill patients and to provide dosing guidelines for this drug.

Read the detailed description

Due to the lack of new antibiotics for the treatment of critically ill patients with multidrug-resistant bacteria, interest in "old" antibiotics like colistin re-emerged. Lastly, colistin is administered more frequently especially in cases of infections due to Pseudomonas aeruginosa, Klebsiella pneumoniae or Acinetobacter baumanii in intensive care units (ICUs) around the world. However, dosing of colistin in critically ill patients undergoing renal replacement therapy is based on scarce data. The aim of this study is to evaluate single and multiple-dose pharmacokinetics of both colistin and its inactive prodrug colistin-methanesulfonate (CMS) in critically ill patients with acute kidney injury (AKI) undergoing extended daily dialysis (EDD).

The investigators perform a prospective clinical pharmacokinetic single- and multiple-dose study in the medical and surgical ICUs of the Hannover Medical School. ICU patients with anuric AKI being treated with EDD and receiving i.v. colistin are studied on day 1 and (if possible) on day 5-9 of treatment. A loading dose of 6 Mio IU colistin ís administered 8 hours prior to the EDD session followed by 3 Mio IU every 8 hours. Colistin Plasma concentration levels as well as dialyzer clearance rates are measured at different time points.

What is being measured

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

  1. Colistin elimination during extended dialysis

    Colistin elimination during extended dialysis is measured on day 1 and day 9 after colistin therapy was started. Colistin elimination is measured by the total eliminated drug amount in the total spent dialysate

    Measured: Participants will be followed for 10 days. Colistin elimination measured by the total drug amount in the collected spent dialysate

Secondary outcomes (3)
  1. Colistin peak concentration during extended daily dialysis C(max)

    Measured: Participants will be followed for 10 days. Colistin concentration is measured at different time points after drug infusion: 0, 0.5, 1, 1.5, 2, 4, 6, 8) on day 1 and day 9 after therapy initiation

  2. Colistin trough Level during extended daily dialysis C(max)

    Measured: Participants will be followed for 10 days. Colistin concentration is measured at different time points after drug infusion: 0, 0.5, 1, 1.5, 2, 4, 6, 8) on day 1 and day 9 after therapy initiation

  3. Colistin dialyzer clearance during extended dialysis

    Measured: Participants will be followed for 10 days. Dialyzer clearance is calculated after 30 and 180 minutes of extended dialysis on day 1 and day 9 after therapy initiation

Questions about this trial

What is this clinical trial studying?

An observational study of Infection Due to Resistant Bacteria and Acute Kidney Injury, run by Hannover Medical School at 1 site in Germany.

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 3 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 24 Aug 2016. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in Germany. 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.

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?

Colistin elimination during extended dialysis (time frame: Participants will be followed for 10 days. Colistin elimination measured by the total drug amount in the collected spent dialysate). It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT02556190, which also lists 1 linked publication.

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 24 Aug 2016.
