Clinical trials

The European Union Clinical Trials Register   allows you to search for protocol and results information on:
  • interventional clinical trials that were approved in the European Union (EU)/European Economic Area (EEA) under the Clinical Trials Directive 2001/20/EC
  • clinical trials conducted outside the EU/EEA that are linked to European paediatric-medicine development

  • EU/EEA interventional clinical trials approved under or transitioned to the Clinical Trial Regulation 536/2014 are publicly accessible through the
    Clinical Trials Information System (CTIS).

    The EU Clinical Trials Register currently displays   43843   clinical trials with a EudraCT protocol, of which   7282   are clinical trials conducted with subjects less than 18 years old.   The register also displays information on   18700   older paediatric trials (in scope of Article 45 of the Paediatric Regulation (EC) No 1901/2006).

    Phase 1 trials conducted solely on adults and that are not part of an agreed paediatric investigation plan (PIP) are not publicly available (see Frequently Asked Questions ).  
    Examples: Cancer AND drug name. Pneumonia AND sponsor name.

    E.2.3Trial contains a sub-study No
    E.3Principal inclusion criteria
    subject will be eligible for inclusion in this study only if all of the following criteria apply:
    1. Signed and dated written informed consent is required prior to a subject’s participation in the study and the performance of any protocol-specific procedures.
    At sites where enrollment of adolescents is allowed, adolescents aged 12 to 17 years must provide written agreement to participate in the study in accordance with applicable regulatory and country or state requirements.
    Subjects will also be asked to sign a release for medical records at the time of consenting to allow access to both the maternal and neonatal records including information about delivery and infant care as well as information collected prior to the consent having been signed NOTE: Prescreening alone does not necessarily require consent as this activity may be accomplished in the absence of study-specific procedures or assessments. In many cases, standard care and standard medical triage will provide sufficient information or evidence as to whether or not the subject is eligible for the study
    2. Females aged 12 to 45 years, with an uncomplicated, singleton pregnancy and intact membranes in spontaneous preterm Labour (NOTE: Since local laws, customs, and institutional practice vary globally, investigator discretion in the enrollment of pediatric subjects is permitted, expect in Italy)
    Italian Subjects: In Italy, the age restriction for study enrollment is 18 to 45 years.

    3. Gestational age between 240/7 and 336/7 weeks as determined by (1) known fertilization date, either in vitro fertilization or intrauterine insemination or (2) a best estimated due date confirmed or established by the earliest ultrasound performed before 240/7 weeks gestation.

    In situations where prenatal ultrasound records are not available at the time the subject presents, the investigator may enroll the subject using the GA based on a verbal history from the subject with the intent of getting confirmation from the medical records or from the subject's primary care obstetrician as soon as possible.

    4. Females must be diagnosed with preterm labor according to both of the following criteria (a and b):
    a. Regular uterine contractions, confirmed by tocodynamometry, at a rate of ≥4 contractions of at least 30 seconds’ duration during a 30-minute interval. Where tocodynamometry is not technically feasible, assessment by manual palpation will be permitted and must be documented.


    b. At least 1 of the following:

    i. Cervical dilation ≥2 cm and ≤4 cm by digital cervical examination OR
    ii. If <2 cm dilation by the required initial digital cervical examination, a cervical change (2 examinations must be documented) consistent with 1 of the following:
    -An absolute increase of at least 25% effacement (e.g. a change in effacement from 50% to 75%) by digital examination or a 10-mm decrease in cervical length by transvaginal ultrasound.
    -A 1-cm increase in cervical dilation by digital cervical examination

    5. Current or past tocolytic treatment as follows:
    a. Subjects in whom tocolytic treatment has not been initiated prior to consent are eligible for the study
    b. Transferred or referred subjects for whom parenteral magnesium sulfate treatment has been started before Screening are eligible provided they meet all eligibility criteria
    c. Subjects receiving a prohibited tocolytic in this study are eligible only if the treatment is stopped before randomization and provided they meet all eligibility criteria
    d. Subjects with a historical failure of a tocolytic treatment in a previous episode of preterm labor during the current pregnancy are eligible provided they meet all eligibility criteria
    E.4Principal exclusion criteria
    A subject will not be eligible for inclusion in this study if any of the following criteria
    1. Fever with a temperature >100.4°F (38°C) for more than 1 hour or ≥101°F (38.3°C) in the 24 hours prior to the start of study treatment
    2. Women with maternal-fetal conditions that potentially necessitate the need for delivery, such as pre-eclampsia or fetal compromise
    3. A fetus with any diagnosis, condition, treatment, or other factor that in the opinion of the investigator has the potential to affect or confound assessments of efficacy or safety (e.g., nonreassuring fetal status, intrauterine growth restriction, major
    congenital anomaly)
    4. Preterm premature rupture of membranes
    5. Women with any confirmed or suspected contraindication to prolongation of pregnancy, such as placental abruption, chorioamnionitis, or placenta previa
    6. Evidence of polyhydramnios (amniotic fluid index [AFI] >25 cm) or oligohydramnios (AFI <5 cm).
    7. Women with co-morbid medical or obstetric conditions that in the opinion of the investigator have the potential to complicate the pregnancy course and outcomes, such as uncontrolled hypertension or uncontrolled diabetes (if known, history of glycosylated hemoglobin
    >8% at any time during pregnancy), known or suspected maternal Zika infection during gestation (see SPM for details), or compromise the safety of the subject, such as underlying cardiovascular disorder (specifically ischemic cardiac disease, congenital heart disease, pulmonary hypertension, valvular heart disease, arrhythmias, and cardiomyopathy)
    8. Women with a history of substance abuse during the pregnancy or dependency that may have the potential to complicate the pregnancy outcome
    9. Women with any diagnosis, condition, treatment, or other factor that, in the opinion of the investigator, has the potential to affect or confound assessments of efficacy or safety
    10. Current active liver or biliary disease (with the exception of Gilbert’s syndrome or asymptomatic gallstones or otherwise stable chronic liver disease per investigator assessment)
    Stable chronic liver disease should generally be defined by the absence of ascites, encephalopathy, coagulopathy, hypoalbuminemia, esophageal or gastric varices, or persistent jaundice, or cirrhosis
    Chronic stable hepatitis B and C (e.g., presence of hepatitis B surface antigen (or positive hepatitis C antibody test result at Screening or within 3 months prior to first dose of study treatment) are acceptable if subject otherwise meets entry criteria
    11. History of sensitivity to any of the IPs or components thereof or a history of drug or other allergy that, in the opinion of the investigator or PPD medical monitor, contraindicates the subject’s participation
