Expanded access (not trials)

Expanded access
Not a trial. This treatment can be requested outside a study, case by case, for people who qualify.
Expanded access (paused)
Not a trial. The treatment can normally be requested outside a study, but is unavailable right now.
Expanded access (ended)
Not a trial. The treatment could once be requested outside a study, but no longer can.
Approved
The treatment has been approved, so it is available normally rather than through this programme.

Summary

Researchers are testing whether tranexamic acid, a drug used to reduce bleeding, can lower the risk of wound healing problems after total ankle replacement surgery. About 40 patients having ankle replacement will be randomly assigned to receive either tranexamic acid or a saltwater placebo during and after surgery. Neither the patients nor their doctors will know which treatment was given. The study will track wound healing, infections, and additional surgeries for six months to see if a larger trial is feasible and whether the drug might help recovery.

What this could mean

Our plain-language read of the trial. This is informational only, not medical advice or a prediction.

Active substance
tranexamic acid, a drug that helps reduce bleeding
What this could lead to
If it works, tranexamic acid could become a routine addition to ankle replacement surgery to lower the risk of wound problems and repeat operations.
What could go wrong
This is a small pilot study of 40 people, so it may not show a clear benefit or may not be large enough to detect rare side effects. Tranexamic acid can cause allergic reactions or blood clots in some patients.

Copied word for word from the study's registry entry, so the wording is the study team's rather than ours.

Inclusion Criteria: * Patient undergoing either primary or revision ankle replacement surgery * Patient is considered to benefit from surgical management at the treating surgeon's discretion * The patient is willing and able to provide written informed consent * The patient is willing and able to comply with post-operative rehabilitation protocols and all follow-up visits Exclusion Criteria: * Pregnant or breastfeeding patient * Uncontrolled diabetes (HgbA1C \> 8) * Known allergy or contraindication for tranexamic acid use including: presence of coronary stents, cerebrovascular event in the last six months, known thromboembolic disorder, hepatic dysfunction, impaired renal clearance, medications with known drug interactions\*\*\* * Lateral-based ankle replacement system * Patient receiving anticoagulation therapy * Investigator concerns about study compliance * Medically unfit for surgery or anesthetic * Acquired color vision problems that are not genetics * There are potential drug-drug interactions leading to myocardial infarction after coadministration of tranexamic acid with hormonal contraceptives, hydrochlorothiazide, desmopressin, sulbactam-ampicillin, carbazochrome, ranitidine, or nitroglycerin. Therefore, patients on these medications will be excluded.
