Women at increased risk for preterm delivery.\n2. A subpopulation, among those receiving the active drug, who may respond to progesterone.\n\nIf fFN and/or E3 identify a population of patients who respond to progesterone, these diagnostic tests may define women who may or may not be good candidates for progesterone therapy.', 'detailedDescription': "Preterm birth occurs in approximately 12% of all pregnancies in the United States and is the leading cause of neonatal morbidity and mortality. Despite extensive efforts the preterm birth rate has risen 25% in the United States over the last two decades. Women with multi-fetal pregnancies are at especially high risk of preterm birth. About half of twin pregnancies and almost all triplet pregnancies result in preterm birth. Thus, women with multi-fetal gestations appear to be a group that would benefit most from a screening intervention to determine those pregnancies at greatest risk for preterm birth. Currently, two biochemical, diagnostic tests for preterm birth are approved by the FDA: fetal fibronectin and salivary estriol testing. Recent studies have shown that weekly administration of 17-alpha-hydroxyprogesterone significantly reduced preterm delivery in singleton pregnancies. The proposed study will assist in the assessment of women who will benefit most from progesterone injections by clarifying it's mechanism of action through the evaluation of serial fFN and E3 samples in a subset of women currently enrolled in a multi-center trial evaluating 17-alpha-hydroxyprogesterone caproate in twin and triplet pregnancies.\n\nThis is a prospective observational study following the results of serial fetal fibronectin and salivary estriol samples in a subpopulation of women with twin pregnancies currently enrolled in a primary trial of weekly injections of 17-alpha-hydroxyprogesterone caproate versus placebo injections. Subjects will be recruited from a large perinatology practice consisting of four outpatient clinics in the Phoenix metropolitan area."}, 'eligibilityModule': {'sex': 'FEMALE', 'stdAges': ['ADULT'], 'maximumAge': '60 Years', 'minimumAge': '18 Years', 'samplingMethod': 'NON_PROBABILITY_SAMPLE', 'studyPopulation': 'Pregnant women (Twins or Triplets) already enrolled in the Obstetrix Clinical Trial " Progesterone for prevention of PTB in twin and triplet pregnancies"', 'healthyVolunteers': False, 'eligibilityCriteria': 'Inclusion Criteria:\n\n1.
