Study summary

Tranexamic acid is commonly administered intravenously during cardiac surgery to reduce perioperative bleeding. Oral tranexamic acid may offer a simpler and less costly alternative, but its effectiveness in patients undergoing off-pump coronary artery bypass grafting has not been adequately established.

TRANSCAB is a randomized, double-blind, parallel-group, non-inferiority clinical trial comparing oral and intravenous tranexamic acid in adults undergoing elective off-pump coronary artery bypass grafting. Participants will receive either oral tranexamic acid before surgery with an intravenous placebo at induction, or oral placebo before surgery with intravenous tranexamic acid at induction.

The primary objective is to determine whether oral tranexamic acid is non-inferior to intravenous tranexamic acid for reducing postoperative blood loss. Secondary objectives include comparing transfusion requirements, postoperative hemoglobin levels, reoperation for bleeding, thromboembolic complications, seizures, acute kidney injury, and other postoperative outcomes.

Read the detailed description

Perioperative bleeding remains an important complication of coronary artery bypass surgery and may lead to blood transfusion, reoperation, prolonged hospitalization, and increased postoperative morbidity. Tranexamic acid is an antifibrinolytic drug widely used in cardiac surgery to reduce bleeding and transfusion requirements. It is most commonly administered intravenously, although oral administration may provide adequate systemic exposure while simplifying drug preparation and administration.

TRANSCAB is a monocentric, prospective, randomized, double-blind, placebo-controlled, parallel-group, non-inferiority trial conducted in adult patients undergoing elective off-pump coronary artery bypass grafting.

A total of 160 participants will be randomized in a 1:1 ratio to one of two treatment groups:

  1. Oral tranexamic acid group: four 500 mg tranexamic acid tablets administered approximately 2 hours before surgical incision, together with an intravenous placebo administered at induction or incision according to the study protocol.
  2. Intravenous tranexamic acid group: four matching oral placebo tablets administered approximately 2 hours before surgical incision, together with 1 g intravenous tranexamic acid administered at induction or incision according to the study protocol.

Participants, clinicians involved in perioperative management, outcome assessors, and investigators will remain blinded to treatment allocation. Study treatments will be prepared and dispensed according to the randomization list by the hospital pharmacy.

The primary objective is to assess whether oral tranexamic acid is non-inferior to intravenous tranexamic acid in reducing postoperative blood loss following off-pump coronary artery bypass grafting.

Secondary and safety outcomes will assess perioperative transfusion requirements, postoperative hemoglobin changes, clinically significant bleeding, reoperation for bleeding, thromboembolic events, seizures, acute kidney injury, mortality, duration of intensive care and hospital stay, and other postoperative complications specified in the protocol.

Inclusion criteria

  1. Age 18 years or older.

  4. Written obtained before randomization.
  5. Routine preoperative laboratory results available, including at least and serum creatinine measured within 30 days before surgery.
  6. Available for in-hospital follow-up and Day 30 assessment.

Exclusion criteria

Exclusion Criteria:

  1. Emergency surgery, non-isolated cardiac surgery, or planned on-pump coronary artery bypass grafting.
  2. Inability to provide or comply with the required follow-up.
  3. to tranexamic acid or any of the study products.
  4. or precaution to tranexamic acid according to the applicable product information, including:

    • active arterial or venous thromboembolic disease or active intravascular clotting;
    • history of subarachnoid hemorrhage;
    • acquired defective color vision;
    • clinically relevant seizure disorder or previous tranexamic-acid-associated seizure;
    • disseminated intravascular coagulation without predominant hyperfibrinolysis;
    • active upper urinary tract hematuria with a risk of ureteric obstruction.
  5. Renal function incompatible with the fixed protocol dose, including estimated below 30 mL/min/1.73 m² or dialysis.
  6. Contraindication to either administration route, including inability to swallow tablets, malabsorption precluding oral dosing, or inability to obtain intravenous access.
  7. Pregnancy or breastfeeding.
  8. Participation in another interventional clinical trial that could interfere with study outcomes or safety.
  9. Planned use of another antifibrinolytic agent outside the protocol, including aprotinin or epsilon-aminocaproic acid.
  10. Any new clinical condition identified after randomization but before dosing that, in the investigator's judgment, makes administration of the study treatment unsafe.
  11. Uncontrolled hemodynamic or respiratory instability before administration of the study intervention.
Terms in these criteria, in plain language(7)

Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.

Informed consent

Before you join, the study team explains what taking part involves — its purpose, what happens, the risks and possible benefits — and answers your questions, so you can decide freely. Consent is usually recorded on a form (the informed consent form, ICF) signed by you or, where the law allows, by someone legally authorised to decide for you.

You can keep asking questions during the study, you are told of new information that matters, and you can choose to leave at any time.

Hemoglobin (Hb)

The protein in red blood cells that carries oxygen. A low level is anaemia, which can cause tiredness and breathlessness. Measured in g/dL or g/L (9 g/dL is 90 g/L).

Hypersensitivity

An allergy, or another reaction of the immune system, to a substance. “Hypersensitivity to the study drug” means a known allergic reaction to it — not every side effect a medicine can have.

Excipients

The other ingredients in a medicine besides the active drug, such as fillers, colours or preservatives.

Contraindication

A reason a treatment, test or procedure should not be given to a particular person, such as an allergy, another illness or a medicine they take.

Clinically significant

Judged by the study doctor to matter for your health or for the study. It is a doctor’s decision, so ask the study team if you are unsure whether something counts.

GFR and eGFR (kidney filtering)

GFR (glomerular filtration rate) is how much blood the kidneys filter each minute. It is usually estimated from a blood test — eGFR, by formulas such as CKD-EPI or MDRD — and some studies ask for it to be measured directly instead. Usually given in mL/min/1.73 m².

Check the method, the units and the minimum the study states. A value of 90 or above is in the normal-or-high range, but kidney damage can show in other tests too.

What these dates mean
Start.
When the first participant enrolled; while estimated, when the study expects to open to recruitment.
Primary completion.
When the last participant was examined or treated to collect data for the study's main question, its primary outcome. A study that stopped early gives the date its data collection stopped.
Completion.
When the last participant's last visit took place, for every outcome, secondary ones and side effects included: the end of the study. Often later than primary completion, sometimes the same day.
Actual and Est.
Actual means the registry says the date has happened. Est. (estimated) is a date the sponsor plans or expects. It can still move, and the sponsor is expected to change it to actual once it has passed.
No changes since tracking began. The registry record was last updated on Jul 31, 2026, before this site started recording changes on Sep 25, 2026. Its history is on ClinicalTrials.gov ↗
