What is being measured
The primary outcome is the main question the study is designed to answer.
Number of Participants With One or More Adjudicated Events of Bleeding (Major or Non-major) With Onset Within 24 Hours After Study Drug Administration
Post-treatment events of bleeding were evaluated by a medically-qualified, blinded member of the surgical team (Blinded Safety Assessor), in consultation with the surgeon, to determine if an event was a "suspected, unanticipated adverse event of bleeding" (SUAEB). A SUAEB is an event of bleeding outside the usual boundaries of expectations for a participant (e.g., in amount of blood lost, prolonged duration of bleeding, or other factors) considering the type of procedure as well as participant's specific surgical experience and underlying risk of bleeding. In addition, blinded review of clinical and laboratory databases was performed to identify any event potentially consistent with a SUAEB; these were reviewed by the Blinded Safety Assessor, who determined if any was a SUAEB. All SUAEBs were evaluated by a blinded external Adjudication Committee, which classified each as either: 1) a major bleeding event, 2) a non-major bleeding event, or 3) not an unanticipated event of bleeding.
Measured: Up to 24 hours post study drug administration
Secondary outcomes (7)
Percent Change From Baseline in Activated Partial Thromboplastin Time (aPTT) at 10 and 60 Minutes Post Study Drug Administration
Change from baseline in aPTT is identified in study protocol as the Key Secondary Outcome Measure. Blood samples for determination of aPTT values were obtained at baseline and at 10 and 60 minutes after study drug administration. aPTT is a performance indicator measuring the efficacy of the intrinsic and common blood coagulation (blood clotting) pathways. Higher values of aPTT indicate a reduction in the clotting tendency of blood.
Measured: Baseline, 10 and 60 minutes post study drug administration
Percent Change From Baseline in Prothrombin Time (International Normalized Ratio) (PT[INR]) at 10 and 60 Minutes Post Study Drug Administration
Change from baseline in PT(INR) is identified in study protocol as an Other Secondary Outcome Measure. Blood samples for determination of PT(INR) values were obtained at baseline and at 10 and 60 minutes after study drug administration. PT(INR) is a performance indicator measuring the efficacy of the extrinsic and common blood coagulation (blood clotting) pathways. The INR is the ratio of a participant's prothrombin time to a normal (control) sample, raised to the power of the International Sensitivity Index (ISI) value for the analytical system used (INR = [PT-Test/PT-Normal]^ISI). Higher values of PT(INR) indicate a reduction in the clotting tendency of blood.
Measured: Baseline, 10 and 60 minutes post study drug administration
Number of Participants With One or More Adjudicated Events of Bleeding (Major or Non-major) With Onset Within 14 Days After Study Drug Administration
This Measure is identified in study protocol as an Other Secondary Outcome Measure. Post-treatment events of bleeding were evaluated by a medically-qualified, blinded member of the surgical team (Blinded Safety Assessor), in consultation with the surgeon, to determine if an event was a "suspected, unanticipated adverse event of bleeding" (SUAEB). A SUAEB is an event of bleeding outside the usual boundaries of expectations for a participant considering the type of procedure as well as participant's specific surgical experience and underlying risk of bleeding. In addition, blinded review of clinical and laboratory databases was performed to identify any event potentially consistent with a SUAEB; these were reviewed by the Blinded Safety Assessor, who determined if any was a SUAEB. All SUAEBs were evaluated by a blinded external Adjudication Committee, which classified each as either: 1) a major bleeding event, 2) a non-major bleeding event, or 3) not an unanticipated event of bleeding.
Measured: Up to 14 days post study drug administration
Number of Participants With One or More Adjudicated Major Events of Bleeding With Onset Within 24 Hours After Study Drug Administration
This Measure is identified in study protocol as an Other Secondary Outcome Measure. All SUAEB were evaluated by a blinded external Adjudication Committee. Major bleeding event (MBE) = one or more of the following: 1) Fatal bleeding; 2) Bleeding that is symptomatic and occurs in critical area/organ, in a non-operated joint, or is intramuscular with compartment syndrome; 3) Extrasurgical site bleeding causing a fall in hemoglobin (Hgb) level of 20 g/L (1.24 mmol/L) or more, or leading to transfusion of two or more units of whole blood or red blood cells (RBCs), occurring within 24 hours of the bleeding; 4) Surgical site bleeding requiring second intervention, or bleeding at operated joint that interferes with rehabilitation; or 5) Surgical site bleeding that is unexpected/prolonged and/or causes hemodynamic instability, with fall in Hgb level of at least 20 g/L (1.24 mmol/L) or transfusion of at least two units of whole blood or RBCs, occurring within 24 hours of the bleeding.
Measured: Up to 24 hours post study drug administration
Number of Participants With One or More Adjudicated Major Events of Bleeding With Onset Within 14 Days After Study Drug Administration
This Measure is identified in study protocol as an Other Secondary Outcome Measure. All SUAEB were evaluated by a blinded external Adjudication Committee. MBE = one or more of the following: 1) Fatal bleeding; 2) Bleeding that is symptomatic and occurs in critical area/organ, in a non-operated joint, or is intramuscular with compartment syndrome; 3) Extrasurgical site bleeding causing a fall in Hgb level of 20 g/L (1.24 mmol/L) or more, or leading to transfusion of two or more units of whole blood or RBCs, occurring within 24 hours of the bleeding; 4) Surgical site bleeding requiring second intervention, or bleeding at operated joint that interferes with rehabilitation; or 5) Surgical site bleeding that is unexpected/prolonged and/or causes hemodynamic instability, with fall in Hgb level of at least 20 g/L (1.24 mmol/L) or transfusion of at least two units of whole blood or RBCs, occurring within 24 hours of the bleeding.
Measured: Up to 14 days post study drug administration
Number of Participants With One or More Adjudicated Venous Thromboembolic (VTE) Events With Onset Within 14 Days After Study Drug Administration
This Measure is identified in study protocol as an Other Secondary Outcome Measure. Suspected symptomatic VTE events were evaluated by a blinded external Adjudication Committee. The confirmation of a VTE event was based on determination of a clinically meaningful venous thrombosis (e.g., pulmonary embolism or deep vein thrombosis).
Measured: Up to 14 days post study drug administration
Number of Participants With One or More Adjudicated Events of Anaphylaxis With Onset Within 14 Days After Study Drug Administration
This Measure is identified in study protocol as an Other Secondary Outcome Measure. Anaphylaxis is a serious allergic reaction that is rapid in onset and may cause death. Adverse events suggestive of hypersensitivity which met defined criteria (e.g., serious event) and/or suspected events of anaphylaxis were evaluated by a blinded external Adjudication Committee to determine whether such events met either of the following two criteria for anaphylaxis (Sampson et al. J Allergy Clin Immunol 2006;117:391-7) - 1. Acute onset of an illness with involvement of the skin, mucosal tissue or both, and at least one of the following: a) respiratory compromise, b) reduced blood pressure (BP) or associated symptoms of end-organ dysfunction. 2. Two or more of the following that occur rapidly after exposure to a likely allergen for that participant: a) involvement of the skin-mucosal tissue, b) respiratory compromise, c) reduced BP or associated symptoms, d) persistent gastrointestinal symptoms.
Measured: Up to 14 days post study drug administration

Primary outcome
Number of Participants With One or More Adjudicated Events of Bleeding (Major or Non-major) With Onset Within 24 Hours After Study Drug Administration
Time frame: Up to 24 hours post study drug administration
Post-treatment events of bleeding were evaluated by a medically-qualified, blinded member of the surgical team (Blinded Safety Assessor), in consultation with the surgeon, to determine if an event was a "suspected, unanticipated adverse event of bleeding" (SUAEB). A SUAEB is an event of bleeding outside the usual boundaries of expectations for a participant (e.g., in amount of blood lost, prolonged duration of bleeding, or other factors) considering the type of procedure as well as participant's specific surgical experience and underlying risk of bleeding. In addition, blinded review of clinical and laboratory databases was performed to identify any event potentially consistent with a SUAEB; these were reviewed by the Blinded Safety Assessor, who determined if any was a SUAEB. All SUAEBs were evaluated by a blinded external Adjudication Committee, which classified each as either: 1) a major bleeding event, 2) a non-major bleeding event, or 3) not an unanticipated event of bleeding.

Who may be eligible to take part?
The sponsor lists 10 inclusion and 16 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: finished, as of the sponsor's last update on 12 Feb 2021. 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. 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?
Yes. Results are posted in the registry (first posted 30 Oct 2013). A summary is in the For doctors view, and the full results are on ClinicalTrials.gov.
How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Number of Participants With One or More Adjudicated Events of Bleeding (Major or Non-major) With Onset Within 24 Hours After Study Drug Administration (time frame: Up to 24 hours post study drug administration). 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 NCT01422304, which also lists 1 linked publication.
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 12 Feb 2021.
