Study information

Primary study design	Interventional
Study design	Open-label, randomised, two-armed, parallel-group, multi-centre trial
Secondary study design	Randomised controlled trial
Scientific title	Effectiveness of dalteparin therapy as intervention in recurrent pregnancy loss
Study acronym	ETHIGII
Study objectives	This 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) studied	Pregnant women with a history of recurrent pregnancy loss
Intervention	Patients 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 type	Supplement
Primary outcome measure(s)	Ongoing intact pregnancy at 24 weeks of gestation
Key secondary outcome measure(s)	1. 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)
Completion date	13/01/2011
