Vaginal pessaries will be identical externally but will contain either placebo or 200 mg of natural progesterone (Laboratorios Effik, Madrid, Spain). The treatment will be applied from the 20th week until the 34th week (or until delivery if it occurred earlier). Control visits will be performed at 24, 28, 32 and 34 weeks. Pregnancies will be managed according to each local protocol. An external statistical analysis will be performed on intention to treat basis.\n\nMain outcome measure: Preterm birth rate (\\<37 weeks). Secondary outcome measures: very preterm birth rate (\\<32 weeks); cervical length measured by vaginal ultrasound at each control visit; need for tocolytic treatments; rate of preterm premature rupture of membranes; and perinatal morbidity and mortality.\n\nEstimated period of study: 2006-2008.'}, 'eligibilityModule': {'sex': 'FEMALE', 'stdAges': ['ADULT', 'OLDER_ADULT'], 'minimumAge': '18 Years', 'healthyVolunteers': True, 'eligibilityCriteria': 'Inclusion Criteria:\n\n* Bichorionic biamniotic twin pregnant women\n* = or \\> 18 years old\n\nExclusion Criteria:\n\n* Single pregnancy or monochorionic twin pregnancy or triplets\n* Chronic hepatic pathology, previous alterations in hepatic analysis during anti-contraceptive treatment; or gestational cholestasis in in previous pregnancies.Basal alterations in hepatic analysis profile.\n* Profylactic cerclage until week 14.\n* Basal alterations in renal analysis profile\n* Local allergy to micronized natural progesterone\n* Genital pathology not allowing for correct absorption of medication\n* Fetal anomoly diagnosed after sonograph week 12 and/or 20.\n* Smokers of more than 10 cigarettes/day\n* Consumers of illegal substances'}, 'identificationModule': {'nctId': 'NCT00480402', 'briefTitle': 'Natural Progesterone and Preterm Birth in Twins', 'organization': {'class': 'OTHER', 'fullName': 'Instituto Valenciano de Infertilidad, IVI VALENCIA'}, 'officialTitle': 'Eficacia de Los Suplementos de Progesterona Natural en la prevención Del Parto pretérmino Gemelar', 'orgStudyIdInfo': {'id': 'VLC-VS-0405-507-23'}}, 'armsInterventionsModule': {'armGroups': [{'type': 'EXPERIMENTAL', 'label': '400 mg Progesterone', 'description': 'Approximately one third of the bichorionic biamniotic twin pregnant women randomized to the 400 mg Progesterone Group vaginal pessaries arm.', 'interventionNames': ['Drug: 400 mg Progesterone']}, {'type': 'EXPERIMENTAL', 'label': '200 mg Progesterone Group', 'description': 'Approximately one third of the bichorionic biamniotic twin pregnant women randomized to the 200 mg Progesterone Group vaginal pessaries arm.', 'interventionNames': ['Drug: 200 mg of Progesterone']}, {'type': 'ACTIVE_COMPARATOR', 'label': 'Placebo', 'description': 'Approximately one third of the bichoronic biamniotic twin pregnant women were randomized to the placebo vaginal pessaries arm.', 'interventionNames': ['Drug: Placebo']}], 'interventions': [{'name': '200 mg of Progesterone', 'type': 'DRUG', 'description': 'Administration of 200 mg of Progesterone', 'armGroupLabels': ['200 mg Progesterone Group']}, {'name': '400 mg Progesterone', 'type': 'DRUG', 'description': 'Administration of 400 mg Progesterone', 'armGroupLabels': ['400 mg Progesterone']}, {'name': 'Placebo', 'type': 'DRUG', 'description': 'Administration of a Placebo', 'armGroupLabels': ['Placebo']}]}, 'contactsLocationsModule': {'locations': [{'zip': '46015', 'city': 'Valencia', 'state': 'Valencia', 'country': 'Spain', 'facility': 'Instituto Valenciano de la Infertilidad', 'geoPoint': {'lat': 39.47391, 'lon': -0.37966}}], 'overallOfficials': [{'name': 'Vicente Serra, MDPhD', 'role': 'STUDY_DIRECTOR', 'affiliation': 'Instituto Valenciano de la Infertilidad'}]}, 'sponsorCollaboratorsModule': {'leadSponsor': {'name': 'Instituto Valenciano de Infertilidad, IVI VALENCIA', 'class': 'OTHER'}}}}
