Nadroparin for the Initial Treatment of Pulmonary Thromboembolism — NATSPUTE  

Pulmonary Embolism Clinical Trial

Official title:
Efficacy and Safety of Body Weight Adjusted Nadroparin vs Standard Unfractionated Heparin for the Initial Treatment of Pulmonary Thromboembolism：a Multi-Centre, Randomised Controlled Trial in China

Clinical Trial Summary

Low-molecular-weight heparin (LWMH) appears to be at least as effective and safe as standard, unfractionated heparin (UFH)for the treatment of patients with deep vein thrombosis(DVT) and may also be so in patients with pulmonary thromboembolism (PTE). Only limited data are available on the evaluation of body weight adjusted LWMH and standard UFH for the initial treatment of PTE in Chinese population. The aim of this study is to determine whether body weight-adjusted, subcutaneous Nadroparin is as effective and safe as UFH for treatment of patients with objectively documented PTE.

Clinical Trial Description

Low-molecular-weight heparin (LWMH) appears to be at least as effective and safe as standard, unfractionated heparin (UFH)for the treatment of patients with deep vein thrombosis(DVT) and may also be so in patients with pulmonary thromboembolism (PTE). Only limited data are available on the evaluation of body weight adjusted LWMH and standard UFH for the initial treatment of PTE in Chinese population.

The aim of this study is to determine whether body weight-adjusted, subcutaneous Nadroparin is as effective and safe as UFH for treatment of patients with objectively documented PTE.

An open-label, adjudicator-blinded, randomized controlled trial of patients with symptomatic non-massive PTE from 37 major hospitals in China is conducted . Intravenous UFH was administered received an initial bolus dose of 80 IU/kg, followed by a continuous infusion at an initial rate of 18 IU/kg /hour. The dose was subsequently adjusted by activated partial thromboplastin time (APTT) monitoring. LMWH (nadroparin) was administered subcutaneously at a dose of 86 anti-factor Xa IU/kg every 12 hours.

Both treatments were overlapped with at least 3 months of warfarin therapy. Main outcome measures were combined end point of clinical effect, image improvement,Recurrent venous thromboembolism(VTE), major bleeding, and death within 14 days and 3 months of randomization. ;
