Topical Tranexamic Acid (TXA) in Hip Fractures

August 15, 2019 updated by: Sault Area Hospital

Topical Tranexamic Acid (TXA) in Hip Fractures, A Double-Blind, Randomized Controlled Trial

Mechanisms by which to reduce exposure to allogeneic blood are of financial and clinical benefit in the hip fracture population. Tranexamic acid (TXA) is an inexpensive medication with low complication risk. Its use in the hip fracture population is unproven. The purpose of this study is to evaluate the efficacy and safety of topical tranexamic acid in reduction of peri-operative blood loss in hip fracture surgery.

Study Overview

Status

Status

Indicates the current recruitment status or the expanded access status.
Completed

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 results of this study may dramatically alter the manner in which surgeons manage hip fracture patients in Canada. The use of topical TXA in operatively-treated hip fracture patients has the potential to reduce perioperative blood loss and consequently reduce exposure to allogeneic blood transfusion. This will positively influence post-operative morbidity and mortality, while at the same time substantially reduce hospital length of stay and overall health care costs. The proposed study is felt to have minimal risk, and is a relatively inexpensive study.

Update: An interim analysis was completed in January 2018. The Data Safety Monitoring Committee reviewed the results and recommend the trial continue as planned.

The final data analysis is in process. The abstract will be uploaded upon completion.

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

18 years to 100 years (Adult, Older Adult)

Accepts Healthy Volunteers

No

Genders Eligible for Study

All

Description

Inclusion Criteria:

All of the following criteria must be met to be eligible:

  1. 18 years of age or older
  2. Diagnosis of hip fracture (Intracapsular, Intratrochanteric or Subtrochanteric) requiring surgical repair
  3. Patient/surrogate decision maker provide signed informed consent

Exclusion Criteria:

Participants cannot be included in this study if any of the following criteria apply:

  1. Patient has documented renal failure with glomerular filtration rate of <30ml/min/1.73m2
  2. Documented allergy to tranexamic acid
  3. Current use of hormone replacement therapy
  4. Acquired disturbances of colour vision
  5. Refusal of blood products
  6. Pre-operative use of anticoagulant therapy (Coumadin, heparin < 5 days of surgery, fibrinolytic disorders requiring intraoperative anti-fibrinolytic treatment)
  7. Coagulopathy (pre-operative platelet count <150,000/mm3, International Normalized Ratio (INR) >1.4, prolonged Partial Thromboplastin Time (PTT) >1.4x normal)
  8. Hematuria
  9. Acute coronary syndrome within 6 weeks of fracture
  10. Any history of venous thromboembolism
  11. Any intraoperative surgical/medical/anesthetic complications i.e.: myocardial infarction or neurovascular injury occurring prior to application of the tranexamic acid
  12. Pregnant or lactating
  13. Any major medical or psychiatric disorder that in the opinion of the investigator, might prevent the subject from completely participating in the study or interfere with the interpretation of the study results
  14. Unable/unwilling to provide informed consent

Arms and Interventions

Participant Group / Arm

Participant Group / Arm

A group or subgroup of participants in a clinical trial that receives a specific intervention/treatment, or no intervention, according to the trial's protocol.
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.

Other: Saline Wash

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
Change in hemoglobin

change in hemoglobin levels day 1 and 3 post-op compared to pre-op values and need for allogenic blood transfusion up to 3 days post-op
1 day and 3 days post-surgery

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.

Time Frame: 30 days post-surgery
30 days post-surgery
Reduced risk of thrombotic event
