Trial Outcomes & Findings for Hip Fracture Study of GSK576428 (Fondaparinux Sodium) (NCT NCT00320424)

NCT ID: NCT00320424

Last Updated: 2018-09-04

Results Overview

Rate (%) was defined as number of events divided by the number of participants evaluated multiplied by 100. Signs and symptoms suggestive of venous thromboembolic events (VTE) included, but were not limited to lower extremity deep vein thrombosis (DVT): erythema, warmth, pain, swelling, tenderness and pulmonary embolism (PE): pleuritic chest pain, dyspnea, cough, hemoptysis, syncope, light-headedness/dizziness, tachypnea, and tachycardia. Intended treatment period started 24±2 hours after surgical closure. Venogram was obtained not later than 2 calendar days after the last study drug administration (between Day 11 and 17). These events were adjudicated by the Central Independent Adjudication Committee of Efficacy (CIACE).

Measure
Fondaparinux Sodium 2.5 mg s.c.
Participants received fondaparinux sodium 2.5 milligrams (mg) by subcutaneous (s.c.) injection for 14 days between Day 2 to Day 11-15. The first injection of the study drug was given 24 ± 2 hours after surgical closure. From Day 3 onwards, the injection of the study drug was given at about the same time every day as far as possible (but more than 12 hours after the first dose on Day 2).

PRIMARY outcome

Timeframe: From the first study drug injection up to Day 17

Population: Full analysis set used which consisted of all participants who were assigned to study drug with the exception of those who did not receive study drug at all and those with no valid efficacy data (example no evaluable venogram).

Rate (%) was defined as number of events divided by the number of participants evaluated multiplied by 100. Signs and symptoms suggestive of venous thromboembolic events (VTE) included, but were not limited to lower extremity deep vein thrombosis (DVT): erythema, warmth, pain, swelling, tenderness and pulmonary embolism (PE): pleuritic chest pain, dyspnea, cough, hemoptysis, syncope, light-headedness/dizziness, tachypnea, and tachycardia. Intended treatment period started 24±2 hours after surgical closure. Venogram was obtained not later than 2 calendar days after the last study drug administration (between Day 11 and 17).

Major bleeding events were defined as clinically unusual bleeding meeting any of the following criteria: fatal bleeding, bleeding including retroperitoneal and intracranial bleeding or bleeding into a critical organ (eye, adrenal gland, pericardium, spine), reoperation due to bleeding/hematoma at the operative site, bleeding leading to a hemoglobin (Hb) fall \>=2 grams per deciliter (g/dL, 1.6 millimoles per liter \[mmol/L\]) within 48 hour of the bleed, bleeding that required a transfusion of red blood cell or whole blood derived from \>=900 millilters (mL) of whole blood within 48 hours of the bleed (excluding the autologous transfusion except for the treatment of bleeding adverse event (AE) and bleeding leading to the bleeding index (BI) \>=2.

An AE was defined as any untoward medical occurrence (MO) in a participant temporally associated with the use of a medicinal product (MP), whether or not considered related to the MP and can therefore be any unfavorable and unintended sign (including an abnormal laboratory finding), symptom, or disease temporally associated with its use. The SAE was any untoward MO that, at any dose, results in death, life threatening, persistent or significant disability/incapacity, results in or prolongs inpatient hospitalization, congenital abnormality or birth defect, that may not be immediately life-threatening or result in death or hospitalization but may jeopardize the participant or may require medical or surgical intervention to prevent one of the other outcomes listed in this definition.
