About this study
Official title: Intraoperative Tranexamic Acid Infusion in Low Dose Versus in High Dose for Reducing Blood Loss and Its Effect on Postoperative Thromboembolic Complications in Radical Cystectomy Operations
Bladder cancer is one of the most common cancers of the genitourinary tract in adults, and its incidence distinctly increases with age . In almost two-thirds of cases, the disease is superficial at presentation and involves the mucosal and sub mucosal layers or the lamina propria of the bladder, whereas ∼20% to 30% of patients have muscle-invasive tumors. Superficial bladder cancer is treated by transurethral endoscopic resection, which can be followed by endovesical therapy for patients at risk of disease recurrence and progression . In contrast, muscle-invasive bladder cancer is generally treated by radical cystectomy with pelvic lymph node dissection and then creation of urinary diversion to create an alternate route for urine passage, which demonstrates 10-year recurrence-free survival rates of 50% to 59% and overall survival rates of ∼45% .
These major surgeries have a prolonged operative times and are associated with significant risk of complications including high risk of perioperative bleeding and subsequent need for blood transfusion with significant postoperative complications, which are reportedly in the range of 24% to 64% .
Read the detailed description
Among individual surgeons at institutions that perform many procedures, median intraoperative blood loss is between 600 and 1700 mL. The incidence of at least one intraoperative blood transfusion is 9 to 67%, and the postoperative transfusion risk is at least 15%. Among cystectomy patients who receive transfusion, a median of 2 units of blood cells are given. Therefore, it is very important to establish surgical and anesthetic protocols aimed at minimizing intraoperative blood loss and subsequent blood transfusion requirements in order to improve postoperative outcomes.
Venous thromboembolism (VTE) in radical cystectomy can account for up to 22% of total deaths after surgery . In the bladder cancer literature, symptomatic thromboembolic events occur in up to 8.3% of patients , but subclinical deep vein thrombosis (DVT) rates can be as high as 24.4% when examining an ultrasonography (US)-screened population . In fact, undergoing a RC is a significant, independent risk factor on multivariable analysis for developing a deep venous thrombosis.
Lysine analog drugs are synthetic derivatives of the amino acid lysine that reversibly block lysine-binding sites on plasminogen molecules. This action prevents the conversion of plasminogen to plasmin, the active enzyme that degrades fibrin clots. Therefore, lysine analogs decrease the breakdown of clots and are considered anti-fibrinolytics. There are two commonly studied lysine analogs, tranexamic acid and epsilon-aminocaproic acid. Both of these drugs have been shown to decrease blood loss and blood transfusion need during some surgeries without a significant increase in adverse events.

Clinical summary
The research question as the sponsor registered it. This describes what the study plans to test, not what it found.
Bladder cancer is one of the most common cancers of the genitourinary tract in adults, and its incidence distinctly increases with age . In almost two-thirds of cases, the disease is superficial at presentation and involves the mucosal and sub mucosal layers or the lamina propria of the bladder, whereas ∼20% to 30% of patients have muscle-invasive tumors. Superficial bladder cancer is treated by transurethral endoscopic resection, which can be followed by endovesical therapy for patients at risk of disease recurrence and progression . In contrast, muscle-invasive bladder cancer is generally treated by radical cystectomy with pelvic lymph node dissection and then creation of urinary diversion to create an alternate route for urine passage, which demonstrates 10-year recurrence-free survival rates of 50% to 59% and overall survival rates of ∼45% .
These major surgeries have a prolonged operative times and are associated with significant risk of complications including high risk of perioperative bleeding and subsequent need for blood transfusion with significant postoperative complications, which are reportedly in the range of 24% to 64% .

Questions about this trial
What is this clinical trial studying?
A Phase 4 study testing Tranexamic acid and Normal saline in people with Bleeding, run by Assiut University.
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 6 inclusion and 5 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: status not confirmed, as of the sponsor's last update on 3 Sep 2020. Status can change between updates, so confirm with the study contact before making plans.
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 4 studies take place after a treatment is approved, to learn more about its long-term benefits and risks in everyday use.
Not every study follows the same path, and some studies (observational studies, device studies) have no phase.
Are results available for this study?
Results are not available in the source record.
How can a doctor refer a patient or contact the research team?
Contact Mohamed Reda Abdelaziz, Professor (01003919165, mohamed.hassan19@med.au.edu.eg), or a site near the patient. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Effect of low dose and high dose tranexemic acid infusion on Intraoperative blood loss . (time frame: within the first 15 days). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
On the ClinicalTrials.gov record for NCT04537533, which also lists 14 linked publications.
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 3 Sep 2020.
