SPORTIF III trial

SPORTIF III study, 2003	TRC2637
	download pdf: ximelagatran \| antithrombotics for atrial fibrillation

Treatments

Studied treatment

ximelagatran 36 mg twice daily

Control treatment

warfarin standard dose (target INR 2-3)

Concomittant treatment

Aspirin

Remarks

Aspirin was used concurrently for at least half the period on study drug by 13% patients assigned to ximelagatran and 10% on warfarin(p=0.01).

Treatments description

INR obtained(mean)

2.5

Patients

One or more stroke risk factor in addition to AF.High risk patients with non valvular atrial fibrillation.

Inclusion criteria

Age >18,Persistent or paroxysmal AF verified by at least 2 ECG,One or more stroke risk factors in addition to AF(hypertension,age>75,previous stroke TIA or systemic embolism,left ventricular dysfunction,age>65+coronary artery disease,age >65+diabete mellitus)

Exclusion criteria

Mitral stenosis,Transient AF caused by reversible disorder,Stroke within the previous 30 days or TIA within 3 days,Condition associated with increased risk of bleeding,Active infective endocarditis,Current atrial myxoma or left ventricular thrombus,Admission for acute coronary syndrome or percutaeous coronary intervention within 30 days,Requirement for chronic anticoagulation treatment for disorders other than AF,planned cardioversion,Planned major surgery,treatment with platelet inhibitor drugs other than aspirin 100mg/day or less within 10 days or fibrinolytic agents within 30 days before randomisation,Regular use of NSAI drugs,Renal insuffiency,Active liver disease or persistent elevationof liver enzymes,Childbearing potential,pregnancy or lactation,Drug addiction alcohol abuse or both,Anaemia or thrombopenia

Method and design

Randomized effectives	1704 / 1703 (studied vs. control)
Design	Parallel groups
Blinding	Open
Follow-up duration	17.4 months
Lost to follow-up	4.1%
Number of centre	259
Geographic area	europe,asia,australasia
Primary endpoint	All stroke or systemic embolism
Remarks	Premature termination of study treatment was the result of study endpoint (4% warfarin group,3% ximelegatran) and adverse effects(4% warfarin group,8% ximelegatran group:this difference is related to elevation of liver enzymes in some patients treated with ximelegatran). The trial was a non inferiority trial but the primary analysis was only by intention to treat.
Withdrawals (T1/T0)	18% / 14%
