Clinical Trial Summary

Fondaparinux is a parenteral anticoagulant drug approved for the prophylaxis of venous thromboembolism in high risk medical patients. A relevant proportion of these patients have renal insufficiency and/or thrombocytopenia which represent independent risk factors for bleeding. The risk of bleeding may be increased when fondaparinux is administered to patients with a reduced renal function and/or low platelet count. A lower dose of fondaparinux, 1.5 mg daily, has been approved for patients with renal insufficiency defined by a creatinine clearance between 20 and 50 mL/min. However, to our knowledge, there are no clinical studies that have specifically evaluated prophylaxis with fondaparinux in acutely-ill medical patients with a moderate to severe thrombocytopenia. The scope of this study is to evaluate the safety of fondaparinux in high risk hospitalized medical patients with a moderate to severe thrombocytopeniada defined by a platelet count between 100,000/uL and 30,000/uL.

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Major bleeding	Major bleeding will be defined as overt bleeding associated with: a fall in hemoglobin of 2 g/dL or more, or leading to a transfusion of 2 or more units of packed red blood cells or whole blood, or bleeding that occurs in a critical site: intracranial, intra-spinal, intraocular, pericardial, intra-articular, intramuscular with compartment syndrome, retroperitoneal or contributing to death.	Participants will be followed for the duration of hospital stay up to two days following hospital discharge, an expected average of 2 weeks
Secondary	Clinically relevant non-major bleeding	clinically relevant non-major bleeding will be defined as overt bleeding not meeting the criteria for major bleeding but associated with medical intervention, unscheduled contact (visit or telephone call) with a physician, (temporary) cessation of study treatment, or associated with discomfort for the patient such as pain, or impairment of activities of daily life.	Participants will be followed for the duration of hospital stay up to two days following hospital discharge, an expected average of 2 weeks
Secondary	Minor Bleeding	All bleeding events that cannot be classified as major or clinically relevant non-major	Participants will be followed for the duration of hospital stay up to two days following hospital discharge, an expected average of 2 weeks
Secondary	Symptomatic venous thromboembolism	Deep vein thrombosis will be confirmed by compression ultrasonography or venography. Pulmonary embolism will be confirmed by spiral computed tomography or V/Q lung scan	Participants will be followed for the duration of hospital stay up to one month after hospital discharge, an expected average of 5 weeks
