Overview
Brief Summary
The purpose of this study is to evaluate the efficacy and safety of the subcutaneous administration for 45 days of Bemiparin (3,500 UI/day) in cancer patients with a CVC, to prevent CVC-related deep venous thrombosis (CVC-DVT)
Detailed Description
Venous thromboembolism (VTE) is a common complication in patients with cancer principally in association with central vein catheters (CVC). The clinical benefit of antithrombotic prophylaxis for CVC-related VTE in cancer patients remains unclear.The aim of this study is to evaluate the efficacy and safety of the administration of Bemiparin in cancer patients with a central venous catheter (CVC). This study is designed as a multicenter, randomized, double-blind, placebo-controlled study. On the day of CVC insertion, eligible patients are randomly assigned to receive subcutaneously either bemiparin (3,500 UI/day) or placebo by using preloaded syringes for 45 days. The primary efficacy endpoint will be the combined incidence during the double blind treatment period of Clinical or symptomatic CVC-DVT verified objectively (Doppler ultrasonography or phlebography)and subclinical or asymptomatic CVC-DVT confirmed by elective bilateral Doppler ultrasonography performed 45±5 days after randomization.
Investigators
Eligibility Criteria
Inclusion Criteria
- •Patients over 18 years old of either sex who have given their informed consent to participate in the study.
- •Patients with a neoplastic process, with a CVC for the administration of anti-tumoral treatment or any other treatment related to the neoplastic process.
- •Patients with a platelet count above 30,000/mm

Exclusion Criteria
- •Patients with a history of clinically evident hemorrhagic episodes and/or with increased bleeding due to any other homeostatic alteration that contraindicates anticoagulant treatment and/or in the past two months have presented at least one of the following: active hemorrhaging or organic lesions susceptible to bleeding (e.g. active peptic ulcer, hemorrhagic cerebrovascular accident, aneurysms).
- •Major surgery in the past two months.

- •Severe arterial hypertension (systolic blood pressure over 200 mmHg and/or diastolic blood pressure over 120 mmHg).
