About this study
Official title: Tranexamic Acid's Effects in Patients Undergoing Laparoscopic Radical Prostatectomy: a Randomized, Double-blind, Placebo-controlled Trial
The study is randomized, placebo-controlled, double-blind clinical trial that aims to check whether tranexamic acid's use in videolaparoscopic radical prostatectomy intraoperative is effective in decrease serum hemoglobin drop and the amount of blood's transfusion.
Read the detailed description
The study aims to check whether tranexamic acid's use in videolaparoscopic radical prostatectomy intraoperative is effective in decrease serum hemoglobin drop and the amount of blood's transfusion.
Therefore it will be a randomized, placebo-controlled, double-blind clinical trial that intends to recruit 122 patients with radical prostatectomy indication who agreed to consent study inclusion.
Patients randomized to intervention group will receive 1,0g of tranexamic acid IV during anesthetic induction, followed by a maintenance dose of 1,0 mg/kg/hour of surgery. Control group will be operated normally.
Data as hemoglobin drop, estimated bleeding volume, need to transfusion, side effects, and presence of lymphocele will be compared between the two groups.

What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
Tranexamic acidDrug
Also called Transamin
Patients with prostate cancer and radical video laparoscopy prostatectomy indication will receive 1,0g of Tranexamic Acid solution IV in bolus 20 minutes before of anesthetic induction, followed by a maintenance hose of 1,0mg/kg/h of surgery.
PlaceboOther
Patients randomized to placebo group will receive physiological saline and will undergo to the radical video laparoscopu prostatectomy normally
| Study group | Role | What they receive |
|---|---|---|
| Tranexamic Acid Group | Experimental | Patients will receive an attack solution of 1,0 g of tranexamic acid 20 minutes before the surgery beginning, followed by a maintence dose of 1,0 mg/kg/h in pump surgery infusion Receives: Drug: Tranexamic acid |
| Placebo Group | Placebo comparator | Patients undergoinf to videolaparoscopic surgery will receive physcological saline as placebo under the same conditions of the tranexamic acid group. Receives: Other: Placebo |
What is being measured
The primary outcome is the main question the study is designed to answer.
Change in serum Hemoglobin levels from preoperative to post operative levels
The serum hemoglobin drop will be evaluated
Measured: Baseline (Before) and 12 and 24 hours after surgery
Secondary outcomes (3)
Estimated volume of bleeding
Total blood loss will be assessed by the volume aspirated during surgery.
Measured: During surgery
Transfusion rate of red blood cell concentrates
The amount of red blood cells concentrate transfused will be evaluated.
Measured: 12 and 24 hours after surgery
Adverse effects tranexamic acid
The adverse effects tranexamic acid administration will be evaluated.
Measured: Up to 30 days after surgery

Questions about this trial
What is this clinical trial studying?
A Phase 3 study testing Tranexamic acid in people with Prostate Cancer, run by Instituto do Cancer do Estado de São Paulo.
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 6 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 18 Apr 2023. 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 3 studies compare the treatment with the current standard treatment or a placebo in a large group, to confirm how well it works and watch for side effects.
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 Caio Brambilla, MD (+554499167029, caiobram@gmail.com), or a site near the patient. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Change in serum Hemoglobin levels from preoperative to post operative levels (time frame: Baseline (Before) and 12 and 24 hours after surgery). 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 NCT05816668, which also lists 33 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 18 Apr 2023.
