Research Excerpts

Overview

Atosiban appears to be effective in delaying preterm birth with a favourable maternal safety profile. There are persisting concerns about the lack of impact on perinatal mortality and morbidity. Atosiban is an effective and safe drug for the acute treatment of preterm labor with minimal side effects.

Effects

Atosiban has been shown to be an effective tocolytic agent with a low rate of side effects during 24 to 33 weeks of gestation. Atosiban is a competitive oxytocin and vasopressin antagonist.

Length of Neonatal Hospital Stay

The length of stay was collected from medical records and was calculated as the days between the delivery date and time and discharge date and time. Log of length of stay was calculated as treatment plus GA at randomization plus established progesterone use based on Analysis of covariance (ANCOVA) model. The p-value was calculated using t-test method. Neonatal ITT Population comprised of all neonates whose mothers were the randomized participants who have been exposed to study treatment, that is, mothers from the ITT Population. (NCT02292771)

Number of Participants With Births Prior to 37 0/7 Weeks Gestation

Gestational age (GA) at birth (weeks) is defined as the GA when the baby is born. Participants were considered to have delivered prior to 37 0/7 weeks, that is preterm , if the GA at birth is less than 37 0/7 weeks.

Time to Delivery From the Start of Investigational Product (IP) Administration

Time to delivery is the number of days from the first dose of study treatment until delivery. The time to delivery was calculated as the days between the delivery and start time of the study treatment infusion using the formula: Time to delivery (days) = (date and time of delivery minus date and time of start of infusion) divided by (24 multiplied by 60). The adjusted mean number of days to delivery along with standard error has been presented. Maternal intent-to-treat (ITT) Population comprised of all mothers randomly assigned to treatment who have been exposed to study treatment irrespective of their compliance to the planned course of treatment.

Neonatal APGAR Scores

APGAR is a quick test to assess the health of new born children. The test is performed at 1 and 5 minutes after birth. APGAR scale is determined by evaluating the new born on five categories (appearance, pulse, grimace, activity and respiration) on a scale from zero to two, then summing up the five values obtained. APGAR score ranges from 0 to 10 where a score of 7 and above is normal. The mean and standard deviation of APGAR scores at one minute and at five minutes of birth has been presented.Only those participants with data available at the specified data points were analyzed.

Number of Infants With a Child Behavior Checklist for Ages 1.5 to 5 Years (CBCL/1.5 to 5) Score Above the 97th Percentile for a Subset of Prespecified Questions That Relate to Attention and Hyperactivity Problems

"The CBCL/1.5 to 5 questionnaire is a parent-completed questionnaire used for assessing behavioral problems and social competencies. It included approximately 100 items that described specific kinds of behavioral, emotional, and social problems that characterized preschool children between the ages of 1.5 and 5 years. Each question could be answered as not true scored as0,somewhat or sometimes true scored as1or very true or often true scored as 2. There were 6 questions related to attention and hyperactivity problems. The responses to those 6 questions were summed (ranged 0 to 12). Total score of 0 to 9 indicated normal, 10 indicated borderline and 11 to 12 indicated significant attention and hyperactivity problems. Scores above the 97th percentile are in the significant range of clinical concern. Number of infants with CBCL/1.5 to 5 score above 97th percentile for subset of pre-specified questions related to attention and hyperactivity problems at 24 months is reported." (NCT02292784)

Number of Infants With Ages and Stages Questionnaire-3 (ASQ-3) Score in the Black Zone for Any Domain at 18 Months

The ASQ-3 included 6 questions in each area, designed to assess 5 areas of development: communication skills, gross motor skills, fine motor skills, problem solving skills, and personal social skills. Parents answered either yes (10 points), sometimes (5 points) or not yet (0 points) to each question to complete ASQ-3. At 18 months, the pre-defined cut-off score for communication was 13.06, gross motor was 37.38, fine motor was 34.32, problem solving was 25.74 and personal social skills was 27.19. Total score was derived by taking mean of all 5 components. Any infant who scored below the cut-off, a score more than or equal to 2 standard deviations below the mean score (that is Black zone in the score chart) in any of the 5 areas of the ASQ-3 was to be referred to a developmental specialist for a formal neurodevelopmental assessment. Number of infants with ASQ-3 scores for any domains in the black zone at 18 months is presented. (NCT02292784)

Number of Infants and Children With Newly Diagnosed Congenital Anomalies (After 28 Days Post Estimated Date of Delivery)

A congenital anomaly is a condition present at birth that results from malformation, deformation, or disruption in 1 or more parts of the body, a chromosomal abnormality, or a known clinical syndrome. Congenital anomaly serious adverse events (SAEs) were examined by the birth defect evaluator. Events were coded per centers for disease control and prevention (CDC) Metropolitan Atlanta congenital defects program (MACDP) criteria and/or European surveillance of congenital anomalies (EUROCAT) criteria. Predefined defect codes specified whether the defect was face and neck, a cleft lip or palate, cardiovascular, respiratory, upper gastrointestinal, female genitalia, male genitalia, renal and urinary system, other musculoskeletal defects, skin, a chromosome anomaly, other organ systems, or a specified syndrome. Number of infants and children with newly diagnosed congenital anomalies reported up to 1 year of chronological age and reported after 1 year of chronological age are presented. (NCT02292784)

Number of Infants Indicated as Needing Further Evaluation After Completion of the Modified Checklist for Autism in Toddlers- Revised With Follow-up (M-CHAT-R/F)

"The M-CHAT-R/F is a parent-reported autism screening tool designed to identify children 16 to 30 months of age who received a more thorough assessment for possible early signs of autism spectrum disorder (ASD) or developmental delay. The M-CHAT-R/F consisted of 20 questions that were answered with either yes, scored as 0 or no, scored as 1. Total scores (ranged 0 to 20) on the M-CHAT-R/F between 0 and 2 indicated a low risk, scores between 3 and 7 indicated a medium risk and triggered administration of the follow-up questionnaire, and scores between 8 and 20 indicated a high risk.

It scaled scores for cognitive, language (receptive and expressive), motor (fine and gross motor). The language and motor areas each have a composite score, with a mean of 100, a SD of 15 and a range of 40 to 160. Scores lower than 70 indicated moderate or severe impairment.
