Nadroparin for the Initial Treatment of Pulmonary Thromboembolism

Status Completed

Clinical Trial Summary

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. ;

Clinical trials are conducted in a series of steps, called phases - each phase is designed to answer a separate research question.

Phase 1: Researchers test a new drug or treatment in a small group of people for the first time to evaluate its safety, determine a safe dosage range, and identify side effects.
Phase 2: The drug or treatment is given to a larger group of people to see if it is effective and to further evaluate its safety.
Phase 3: The drug or treatment is given to large groups of people to confirm its effectiveness, monitor side effects, compare it to commonly used treatments, and collect information that will allow the drug or treatment to be used safely.
Phase 4: Studies are done after the drug or treatment has been marketed to gather information on the drug's effect in various populations and any side effects associated with long-term use.
