About this study

Official title: Role of Low Dose Intra-articular Tranexamic Acid in the Reduction of Blood Transfusions in Primary Total Hip and Total Knee Arthroplasty: A Randomized Placebo Controlled Study

This is a randomized, double blinded, controlled trial in patients undergoing elective Total Knee Arthroplasty (TKA) and Total Hip Arthroplasty (THA). The study group will receive intra-articular Tranexamic Acid (TXA) while the control group will receive normal saline placebo.

Read the detailed description

The primary purpose of this study is to determine if intra-articular administration of low dose TXA following THA and TKA results in a clinically relevant reduction in blood loss. The secondary purpose is to determine if there is an increased risk of thromboembolic phenomena with the use of TXA following elective THA and TKA. The primary outcome metric will be - drop in hemoglobin following surgery; secondary metrics include blood loss, transfusion rate, d-dimers, troponin levels, symptomatic deep venous thrombosis (DVT) and pulmonary embolism (PE), vascular events (myocardial infarction, stroke), major and minor bleeding, and death.

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • Tranexamic AcidDrug

    Also called DIN#: 02246365, Sandoz Canada Inc.

    0.5g Tranexamic Acid in 0.9% Sodium Chloride (study group) will be injected into the joint after final closure through a temporary catheter that is brought out through the incision.

  • PlaceboOther

    Also called Sodium Chloride solution

    0.9% Sodium Chloride (placebo group) will be injected into the joint after final closure through a temporary catheter that is brought out through the incision.

Questions about this trial

What is this clinical trial studying?

A Phase 2 study testing Tranexamic Acid in people with Osteoarthritis, run by Orthopaedic Innovation Centre at 1 site in Canada.

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 4 inclusion and 15 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 10 Apr 2017. 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 Canada. 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. Some participants in this study may receive a placebo. 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 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.

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?

Change from Baseline in hemoglobin during hospital stay (time frame: routinely measured post-op day 1 and 3). 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 10 Apr 2017.
