Study designOpen-label, randomised, two-armed, parallel-group, multi-centre trial
Primary study designInterventional
Secondary study designRandomised controlled trial
Study setting(s)Not specified
Study typeTreatment
Scientific titleEffectiveness of dalteparin therapy as intervention in recurrent pregnancy loss
Study acronymETHIGII
Study objectivesThis study aims at analysing if the rate of pregnancy losses before the 24th week of gestation can be reduced by dalteparin (low molecular heparin) treatment.
Ethics approval(s)Ethics Commission of the Friedrich Schiller University Jena, Faculty of Medicine (Ethikkommission der Friedrich-Schiller-Universität Jena, Medizinischen Fakultät), approval received on October, 26th, 2006 (reference number: 1837-08/06).
Health condition(s) or problem(s) studiedPregnant women with a history of recurrent pregnancy loss
InterventionPatients will be randomised between:
1. Dalteparin 5000 IE daily and multivitamin two tablets daily
2. Multivitamin two tablets daily
Treatment duration: up to the 24th week of gestation
Intervention typeSupplement
Primary outcome measureOngoing intact pregnancy at 24 weeks of gestation
Secondary outcome measures1. Live birth
2. Late pregnancy complication, defined as at least one of the following:
a. preterm delivery (before 37 weeks of gestation)
b. placenta insufficiency
c. intrauterine growth restriction less than fifth percentile
d. preeclampsia
e. abruptio placentae
3. Foetus with structural anomalies
4. Symptomatic thromboembolic events
5. Side effects of dalteparin therapy (e.g. thrombocytopenia, osteoporosis, haemorrhage)
Overall study start date13/11/2006
Completion date13/01/2011
