Hip Fracture Study of GSK576428 (Fondaparinux Sodium)

Rate of Major Bleeding During Treatment Period

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).

Rate of PE During Treatment Period

Rate (%) was defined as number of events divided by the number of participants evaluated multiplied by 100. Signs and symptoms suggestive of VTE included, but were not limited to lower extremity 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 CIACE. It was evaluated from the first study drug injection up to Day 17 or to first venogram, whichever occurred first.

Rate of DVT During Treatment Period

Rate (%) was defined as number of events divided by the number of patients evaluated multiplied by 100. Signs and symptoms suggestive of VTE included, but were not limited to lower extremity DVT: erythema, warmth, pain, swelling, tenderness. 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 CIACE. It was evaluated from the first study drug injection up to Day 17 or to first venogram, whichever occurred first.

Rate of Proximal DVT During Treatment Period

Rate (%) was defined as number of events divided by the number of participants evaluated multiplied by 100. Signs and symptoms suggestive of VTE included, but were not limited to lower extremity DVT: erythema, warmth, pain, swelling, tenderness. 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 CIACE. It was evaluated from the first study drug injection up to Day 17 or to first venogram, whichever occurred first.

Rate of Distal Only DVT During Treatment Period

Rate (%) was defined as number of events divided by the number of participants evaluated multiplied by 100. Signs and symptoms suggestive of VTE included, but were not limited to lower extremity DVT: erythema, warmth, pain, swelling, tenderness. 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 CIACE. It was evaluated from the first study drug injection up to Day 17 or to first venogram, whichever occurred first.

Number of Participants With Major Bleeding During Treatment Period

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. Major bleeding events were adjudicated by the Central Independent Adjudication Committee of Safety (CIACS).

Number of Participants With Minor Bleeding and Any Bleeding (Major and/or Minor Bleeding)

Minor bleeding and any bleeding (major and/or minor bleeding) events were adjudicated by the CIACS. Minor bleeding was defined as clinically overt bleeding not meeting the criteria for major bleeding and considered more than expected in the clinical context. Any bleeding (major and/or minor bleeding) could be recorded may be major and/or minor.

Number of Participants With Adverse Events (AE), Serious Adverse Events (SAE) and Death

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.

Number of Transfused Participants

Blood product transfusions consisted of packed red blood cells or fresh frozen plasma or both. This was done between Day 2 and 2 calendar days after the last injection.

Summary of Units Transfused

Blood product transfusions consisted of packed red blood cells or fresh frozen plasma or both. This was done between Day 2 and 2 calendar days after the last injection.

Rate of Symptomatic DVT

Rate (%) was defined as number of events divided by the number of participants evaluated multiplied by 100. Signs and symptoms suggestive of VTE included, but were not limited to lower extremity DVT: erythema, warmth, pain, swelling, tenderness. 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 CIACE. It was evaluated from the first study drug injection up to Day 17 or to first venogram, whichever occurred first.
