Tranexamic Acid in Total Hip Arthroplasty. (PORTO)

March 11, 2016 updated by: Centre Hospitalier Universitaire de Saint Etienne

Tranexamic Acid in Total Hip Arthroplasty: Single Preoperative Administration vs Perioperative Administration. A Randomized Control Trial.

The purpose of this study is to compare a single preoperative dose of 1g of tranexamic acid (TXA) versus a preoperative dose of 1g of TXA followed by a continuous infusion of 1g over height hours on blood loss.

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Detailed Description

The purpose of this study is to compare a single preoperative dose of 1g of tranexamic acid (TXA) versus a preoperative dose of 1g of TXA followed by a continuous infusion of 1g over eight hours on blood loss. The efficacy of TXA on blood loss is greatly influenced by the timing of its administration relative to surgery. In total hip arthroplasty, TXA should be started before surgery. However the optimal duration of TXA administration in hip arthroplasty is unknown. Numerous studies have shown that a single preoperative administration of TXA is effective. Yet indirect comparisons indicate a higher efficacy of TXA started before surgery and followed with a continuous infusion or repeated boluses. Our hypothesis is that a single preoperative administration of TXA is not sufficient to maintain therapeutic concentrations of TXA in the postoperative period. In addition a pharmacokinetic/pharmacodynamic study will be performed to identify the contribution of TXA plasma concentration as a predictor of blood loss.

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

14 years and older (Adult, Older Adult)

Accepts Healthy Volunteers

No

Genders Eligible for Study

All

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Calculated volume of blood losses in the peroperative period.
Time Frame: between the beginning of surgery and the fifth day
It requires the sampling of haemoglobin at the beginning of surgery and in the fifth day.
between the beginning of surgery and the fifth day

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Measure Description
Time Frame
the patients' percentage that will receive the transfusion of at least one allogenic globular sediment
Time Frame: between D1 (day of surgery) and D5 (the fourth postoperative day)
the patients' percentage that will receive the transfusion of at least one allogenic globular sediment in the peroperative period.
between D1 (day of surgery) and D5 (the fourth postoperative day)
incidence of symptomatic thrombotic events and death
Time Frame: in 6 weeks
combined criteria of venous events (deep venous thrombosis or pulmonary embolism), arterial events (acute coronary syndrome, stroke or peripheral arterial thrombosis) and death
in 6 weeks
tranexamic acid pharmacokinetic analyses
Time Frame: from the beginning of surgery up to 8 hours
non linear mixt effect model
from the beginning of surgery up to 8 hours

Primary Completion (Actual)

Primary Completion

The date on which the last participant in a clinical study was examined or received an intervention to collect final data for the primary outcome measure. Whether the clinical study ended according to the protocol or was terminated does not affect this date. For clinical studies with more than one primary outcome measure with different completion dates, this term refers to the date on which data collection is completed for all the primary outcome measures. The "anticipated" primary completion date is the date that the researchers think will be the primary completion date for the study.
