About this study

Nine patients will be enrolled in this study. After completion of the meropenem therapy for 3 days in this study, all patients will receive other sensitive antibiotics to eradicate their bacterial infections.

Meropenem pharmacokinetic studies were carried out during administration of the third dose of each regimen (16 to 24 h after the start of each regimen). Blood samples (approximately 5 ml) were obtained by direct venipuncture at the following times: before (time zero) and 10 and 30 min and

1, 1.5, 2, 2.5, 3.5, 4, 4.5, 5, 6, and 8 h after the third dose of each regimen.

The concentrations of meropenem were determined by reverse-phase high-performance liquid chromatography.

Concentration of meropenem in plasma will be simulated in Monte Carlo technique (Computer model) to get PK/PD index (40%T>MIC) and reported to % PTA(Probability Target Attainment) and %CFR (Cumulative Faction Response)

Read the detailed description

Introduction:

Meropenem is a carbapenem antibacterial agent with a broad spectrum of activity against several pathogens. In common with other -lactams, the main pharmacokinetic/pharmacodynamic parameter that correlates with the therapeutic efficacy is the T>MIC, and administration by continuous infusion is the preferred route to maximize this parameter. However, in tropical countries the stability of meropenem is an important consideration when continuous infusion is to be used.

Objective:

The aim of this study was to demonstrate the T>MIC of meropenem when administered by a 3-h infusion compared with that when administered by bolus injection.

Study design:

The study was conducted with nine patients with ventilator-associated pneumonia. Each subject received meropenem in three regimens consecutively: (i) bolus injection of 1 g every 8 h for 24 h; (ii) 3-h infusion of 1 g every 8 h for 24 h; and (iii) 3-h infusion of 2 g every 8 h for 24 h.

Sample collections:

Meropenem pharmacokinetic studies were carried out during administration of the third dose of each regimen (16 to 24 h after the start of each regimen). Blood samples (approximately 5 ml) were obtained by direct venipuncture at the following times: before (time zero) and 10 and 30 min and 1, 1.5, 2, 2.5, 3.5, 4, 4.5, 5, 6, and 8 h after the third dose of each regimen.

Meropenem assay:

The concentrations of meropenem were determined by reverse-phase high-performance liquid chromatography. Cefepime (100 mcg/ml) was used as the internal standard, and the samples were extracted by the method of Ozkan et al.

Clinical data and pathogens collection:

  1. Initial patient demographic data (age, sex, weight, diagnosis, APACHE II scores) will be collected upon enrollment in the study.
  2. The Gram negative bacilli isolated from sputum in 9 patients will be collected and the MIC of the meropenem for pathogens will be determined by E tests upon enrollment in the study.

Duration of study:

Patients will receive meropenem for 3 days

Pharmacokinetic and pharmacodynamic analysis:

Concentration of meropenem in plasma will be simulated in Monte Carlo technique (Computer model) to get PK/PD index (40%T>MIC) and reported to % PTA (Probability Target Attainment) and %CFR (Cumulative Faction Response) Sample Size: Nine patients with VAP will be enrolled in this study.

What is being measured

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

  1. Concentration of meropenem in plasma

    Concentration of doripenem in plasma will be simulated in Monte Carlo technique (Computer model) to get PK/PD index (40%T>MIC) and reported to % PTA (Probability Target Attainment) and %CFR (Cumulative Faction Response).

    Measured: 8 hours profile after 3rd dose of meropenem

Questions about this trial

What is this clinical trial studying?

A Phase 4 study testing Meropenem in people with Ventilator-Associated Pneumonia, run by Sutep Jaruratanasirikul at 1 site in Thailand.

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 1 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 25 Nov 2015. 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 Thailand. 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?

Concentration of meropenem in plasma (time frame: 8 hours profile after 3rd dose of meropenem). 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 25 Nov 2015.
