About this study

Official title: Impact of Body Composition Changes and Cachexia on Bisoprolol and Ramipril Pharmacokinetics and Renal Function Estimation in Patients With Chronic Heart Failure

The purpose of this study is to determine if cachexia and changes in body composition influence pharmacokinetics of bisoprolol and ramipril and the accuracy of equations for renal function estimation.

Read the detailed description

Patients with chronic heart failure on treatment with bisoprolol and/or ramipril will be included. Study will consist of two study visits: baseline visit (V1) and visit which will be performed at least 6 months after baseline (V2). At both visits same procedures will be performed. On the day of the visit, patients will be asked to take their morning dose of bisoprolol and/or ramipril after the withdrawal of the first morning plasma sample. Additional 3 to 5 plasma samples will be taken within 5 hours post bisoprolol and/or ramipril dose in order to determine pharmacokinetic profile of both drugs. Body composition will be measured by bioimpedance and dual-energy X-ray absorptiometry. Renal function will be measured by clearance of intravenously administered iohexol. Biochemical parameters, muscle strength, fatigue and anorexia will be assessed in order to determine presence of cachexia.

Changes in body composition will be correlated with changes in pharmacokinetic parameters of bisoprolol and ramipril. Pharmacokinetic parameters in cachectic patients will be compared to pharmacokinetic parameters in non-cachectic patients. Parameters of body composition will be correlated with the difference between measured and estimated renal function.

What is being measured

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

  1. Pharmacokinetic parameters of bisoprolol and ramipril

    Pharmacokinetic parameters of bisoprolol and ramipril(clearance, volume of distribution, area under concentration-time curve, maximal concentration, time to maximal concentration) will be determined. The relation between pharmacokinetic parameters and body composition/cachexia will be assessed.

    Measured: Baseline and 6 months

Secondary outcomes (3)
  1. Body composition

    Body composition (percentage and amount of body fat, lean body mass, dry lean body mass and body water) will be measured by bioimpedance and dual energy X-ray absorptiometry

    Measured: Baseline and 6 months

  2. Cachexia diagnosis

    Cachexia diagnosis (determination of low body mass index, wasting, biochemical parameters, muscle strength, fatigue and anorexia)

    Measured: Baseline and 6 months

  3. Renal function

    Renal function will be measured by clearance of intravenously applied iohexol. Estimation of renal function will be calculated with different equations based on serum creatinine concentration. Measured and estimated renal function will be compared and the differences related to body composition parameters.

    Measured: Baseline and 6 months

Questions about this trial

What is this clinical trial studying?

An observational study of Chronic Heart Failure and Cachexia, run by The University Clinic of Pulmonary and Allergic Diseases Golnik at 1 site in Slovenia.

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 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: status not confirmed, as of the sponsor's last update on 11 Apr 2013. 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 Slovenia. 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?

Results are not available in the source record.

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

Contact Mitja Lainscak, MD, PhD ((0) 4 256 9483 ext. +386, mitja.lainscak@guest.arnes.si), or a site near the patient. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Pharmacokinetic parameters of bisoprolol and ramipril (time frame: Baseline and 6 months). 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 NCT01829880, 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 11 Apr 2013.
