About this study

Official title: A Pharmacokinetic, Pharmacodynamic, and Safety Evaluation of Tirofiban Using a Single High-Dose Bolus In Subjects With Normal Renal Function and Subjects With Moderate-to-Severe Renal Impairment With Non-Dialysis-Dependent Renal Insufficiency (NDDRI)

The purpose of this study is to evaluate tirofiban concentration in the blood over a period of 24 hours after tirofiban administration. Subjects with varying degrees of renal insufficiency (i.e. kidney function) will be included in the study. Tirofiban is known to be cleared from the blood by the kidneys and so people with kidney problems clear tirofiban to a slower extent compared to people without kidney problems. By comparing the tirofiban concentration profile between subjects with healthy kidney function versus with impaired kidney function, a tirofiban dosing recommendation for subjects with impaired kidney function can be made.

This is a non-randomized, single-center, open-label study. A single dose of tirofiban (25 µg/kg administered intravenously over a 3 min period) will be administered to subjects with normal renal function (>90 mL/min CrCl), moderate (30-59 mL/min CrCl), and severe (<30 mL/min CrCl) renal impairment with non-dialysis-dependent renal insufficiency

Read the detailed description

Tirofiban is cleared from the plasma largely by renal excretion. As a consequence, a dosage adjustment of 50% of the tirofiban label dosing regimen (0.4 μg/kg/min for a period of 30 minutes, followed by an infusion of 0.10 μg/kg/min) is recommended in patients with severe renal impairment (<30 mL/min CrCl), including those who require hemodialysis. The dosage adjustment for the tirofiban high-dose bolus regimen (25 μg/kg bolus followed by a 0.15 μg/kg/min maintenance) for patients with varying degrees of renal insufficiency is however unknown. The purpose of this study is to determine the extent of dosage adjustment for the high-dose bolus regimen for patients with moderate (30-59 mL/min CrCl), and severe (<30 mL/min CrCl) renal insufficiency.

This non-randomized, single-center, open-label study evaluating the pharmacokinetic (PK), pharmacodynamic (PD), and safety profile of a single high-dose IV bolus injection of tirofiban (25 µg/kg). A single dose of tirofiban will be administered to the subjects with normal renal function (>90 mL/min CrCl), moderate (30-59 mL/min CrCl), and severe (<30 mL/min CrCl) renal impairment with non-dialysis-dependent renal insufficiency (NDDRI).

What is being measured

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

  1. An analysis of tirofiban plasma concentration in normal, moderate and severe renal impaired adult subjects following a single high-dose bolus (3 min IV infusion) of tirofiban (25 µg/kg).

    Measured: Subject's participation in this study will last 3 days (confinement of 48 hours).

Secondary outcomes (1)
  1. An analysis of platelet aggregation inhibition in normal, moderate and severe renal impaired adult subjects following a single high-dose bolus (3 min IV infusion) of tirofiban (25 µg/kg).

    Measured: Baseline (prior to administration of tirofiban), 15 minutes, 1 hour, and 6 hours following the end of the tirofiban administration.

Questions about this trial

What is this clinical trial studying?

A Phase 1 study testing Tirofiban in people with Renal Insufficiency, run by Medicure at 1 site 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 3 inclusion and 13 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 27 Mar 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 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 1 studies test a treatment in a small group of people for the first time or in a new way, mainly to check safety and find the right dose.

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?

An analysis of tirofiban plasma concentration in normal, moderate and severe renal impaired adult subjects following a single high-dose bolus (3 min IV infusion) of tirofiban (25 µg/kg). (time frame: Subject's participation in this study will last 3 days (confinement of 48 hours).). 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 27 Mar 2014.
