A Dose-response Study of Tranexamic Acid in Total Hip Arthroplasty (PRADO)

Dose Study of Tranexamic Acid in Total Hip Replacement to Reduce Post-operative Hemoglobin Loss: A Phase 2 Randomized Double-blind Monocentric Study

A single preoperative dose of tranexamic acid (TXA) reduces blood loss and red blood cell transfusion in primary hip arthroplasty. Numerous regimens have been tested, ranging from 10mg/kg up to 3g. However the optimal dose to administer is unknown.

Study Overview

Detailed Description

This dose-response study is a randomized double blind study with five groups of 30 patients each. Patients will be randomized to placebo, tranexamic acid (TXA) 300 mg, tranexamic acid (TXA) 500 mg, tranexamic acid (TXA) 1000 mg or tranexamic acid (TXA) 3000 mg. In addition a pharmacokinetic/pharmacodynamic study will be performed to identify the contribution of tranexamic acid (TXA) plasma concentration as a predictor of intra and postoperative D-Dimer values.

What is the study measuring?

Primary Outcome Measures

Outcome Measure
Measure Description
Time Frame
haemoglobin decrease in the perioperative period
Time Frame: Day 1 to Day 8
Percentage of haemoglobin change in the perioperative period. It requires the sampling of haemoglobin just before surgery (Day 1) and on the eighth postoperative day
Day 1 to Day 8

Secondary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Tranexamic acid pharmacokinetics
Time Frame: Day 1
For tranexamic acid pharmacokinetics, the outcome measure is the sampling of tranexamic blood concentration.
Day 1
D-Dimer kinetics
Time Frame: Day 1
For tranexamic acid pharmacodynamics, the outcome is the sampling of D-Dimer levels.
Day 1
allogenic red blood cell transfusion
Time Frame: Day 1 to day 8
For allogenic red blood cell transfusion, the outcome measure will be the percentage of patients that will receive the transfusion of at least one allogenic red blood cell unit in the perioperative period.
Day 1 to day 8
severe anaemia
Time Frame: Day 1 to day 8
For severe anaemia (defined as a level of haemoglobin <10 gram by deciliter), the outcome measure will be the percentage of patients that will have at least one value of haemoglobin <10 gram by deciliter in the perioperative period.
Day 1 to day 8
incidence of symptomatic thrombotic events and death
Time Frame: Day 1 to day 8
For the incidence of symptomatic thrombotic events and death, the outcome measure is a combined criteria of venous events (deep venous thrombosis or pulmonary embolism), arterial events (acute coronary syndrome, stroke or peripheral arterial thrombosis) and death.
Day 1 to day 8
occurrence of a seizure
Time Frame: Day 8
The endpoint is a combined criteria endpoint involving either the clinical observation of a generalized tonic-clonic seizure or a partial seizure or an epilepsy confirmed by an electroencephalogram interpreted by a neurologist blinded to the patient's inclusion group.
Day 8
