About this study

Official title: Pharmacokinetics of Levofloxacin and Capreomycin in MDR-TB Patients

This is an open label observational pharmacokinetic drug study to evaluate Levofloxacine and Capreomycin in patients with Multidrug-Resistant Tuberculosis (MDR-TB).

Read the detailed description

Patients receive MDR-TB treatment with o.a. Levofloxacin and Capreomycin. At least one week after start of treatment, the PK samples samples will be obtained via an intravenous catheter at 0, 1, 2, 3, 4, 7, and 12 hours after intake.

What is being measured

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

  1. AUC/MIC ratio of Levofloxacin

    The primary outcome parameter is the ratio of the in vitro minimum inhibitory concentration (MIC) to the area under the serum concentration-time curve (AUC) over 24 hours (AUC0-24h ), [AUC0-24h /MIC], after administration of Levofloxacin.

    Measured: after day 8 of treatment

  2. Cmax/MIC ratio of Capreomycin

    The primary outcome parameter is the ratio of the in vitro minimum inhibitory concentration (MIC) to the maximum serum concentration, [Cmax/MIC], after administration of Capreomycin.

    Measured: after day 8 of treatment

Secondary outcomes (2)
  1. Volume of Distribution

    Based on the measured drug concentration during the dosing interval and patient characteristics (height, bodyweight and age) the volume of distribution will be calculated

    Measured: after day 8 of treatment

  2. Clearance

    Based on the drug concetrations during the dosing interval and patient characteristics (height, bodyweight, age) the drug clearance will be calculated

    Measured: after day 8 of treatment

Questions about this trial

What is this clinical trial studying?

An observational study of Tuberculosis, run by University Medical Center Groningen at 1 site in Belarus.

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 3 inclusion and 4 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 23 Jun 2014. 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 Belarus. 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?

AUC/MIC ratio of Levofloxacin (time frame: after day 8 of treatment). 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?

On the ClinicalTrials.gov record for NCT02169141, which also lists 2 linked publications.

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 23 Jun 2014.
