Live birth after 24 weeks of gestation

Other Outcome Measures
- Adverse events [Through study completion, up to 11 months]
Treatment emergent adverse events frequency and severity
- Neonatal assessments [Birth of infant until 28 days]
Incidence of any malformation or any significant morbidity during the neonatal period
- Ages and Stages Questionnaires® (ASQ-3™) 6 and 12 month Questionnaire [6 and 12 months after term]
Screening questionnaire composed of 30 questions completed by the parent. Questions are divided into five areas: communication, gross motor, fine motor, problem solving and personal-social. Parents respond yes, sometimes and not yet to questions, these are converted to points 10, 5 and 0 for scoring and are totalled for each developmental area. These 5 area scores are compared with empirically derived cutoff points.
