    Recruitment
    Recruitment details
    		 ZINN was a randomized, double-blind, double-dummy multicenter study to compare efficacy and safety of retosiban versus atosiban in female participants aged 12 to 45 years with an uncomplicated singleton pregnancy in preterm labor with intact membranes between 24 0/7 and 33 6/7 weeks gestation.

    Pre-assignment
    Screening details
    		 From 330 planned participants 100 were enrolled and 97 were randomized to receive either retosiban or atosiban intravenous (IV) infusion in a ratio of 1:1. Two participants randomized to retosiban and 1 participant randomized to atosiban did not receive the study treatment as they were not eligible. The study was terminated early due to feasibility

    		 Time to delivery from the start of investigational product (IP) administration
    End point description
    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.

    End point description
    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.

    Substantial protocol amendments (globally)
    Were there any global substantial amendments to the protocol? Yes
    Date
    Amendment
    29 Jan 2015
    Amendment No. 1 The following changes are reflected in the Country-Specific Protocol Amendment for Applicable Sites in France: Inclusion criteria 1 and 2 were amended to specify that subjects must be at least 18 years of age to participate in Study 200721, and subjects who participate in Study 200721 must also agree to participate in Study 200722, a separate infant follow-up study. Text was revised throughout to reflect the change in the subject age criterion and the requirement to enroll in the infant follow-up study. Section 9.2 was updated to clarify that the study would be conducted using the current version of the Declaration of Helsinki. Finally, an appendix was added that categorizes laboratory samples into those supporting study conduct and those that may be analyzed at a later date.
    29 Jan 2015
    Amendment No. 2 The following changes are reflected in the Country-Specific Protocol Amendment for Applicable United Kingdom Sites: The text from Section 5.3 has been clarified. The intent of the language remains the same, but the clarification confirms there is no requirement for the investigator to discuss unblinding with the PPD medical monitor in order to rapidly unblind treatment for a study subject if needed. In addition, Section 9.2 was updated to clarify that the study would be conducted using the current version of the Declaration of Helsinki
    04 Feb 2015
    Amendment No. 3 The following changes are reflected in the Country-Specific Protocol Amendment for Applicable Swedish Sites: An appendix was added to list the medications considered strong, moderate, and weak CYP3A4 (cytochrome P450 3A4 enzyme) inhibitors and inducers.
    22 Aug 2016
    Amendment No. 4: Clarified the methods for documenting Screening GA. Clarified that co-morbid conditions would exclude a subject with known or suspected maternal Zika infection. Revised guidance regarding adequate treatment response and defined inadequate treatment response. Added procedures to be followed for managing dose interruptions; and allowed pessary use if started before the current episode of preterm labor. Revised the requirements for continuous fetal heart rate monitoring to a minimum of 6 hours from the start of the infusion or from the start of a dose increase, provided the heart rate pattern was consistently reassuring. Clarified that confirmation of uterine contraction eligibility criterion must occur within 60 minutes before study drug dosing. Removed the follow-up amniotic fluid index (AFI) by abdominal ultrasound as a fetal safety endpoint. Removed the requirement for an ultrasound for AFI determination within 12 hours of completion of study treatment. Revised the method used for adjusting multiplicity of the key secondary endpoints from a stepwise Holm’s test to a sequential testing method.
    21 Dec 2016
    Amendment No. 5: Remove the screening urine drug and alcohol tests. Remove requirement that investigator confirm uterine contraction rate and cervical dilation after randomization and just before study drug administration. Add that after randomization and prior to study drug administration investigators will re-assess that tocolytic therapy is still indicated, according to their medical discretion. Clarify that an abdominal ultrasound to assess fetal growth is needed at Screening or before retreatment unless the most recent ultrasound is within 3 weeks (21 days) before the date of randomization or the date of retreatment. Update the list of maternal drug-related events to clarify the reporting process for events of subsequent preterm labor and hospitalization for delivery that are not worse than expected. Add that the amniotic fluid index should be measured using the 4-quadrant method. Remove changes detailed in the country-specific amendment for sites in France (dated 29 Jan 2015). Incorporate other administrative changes.
