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   43871   clinical trials with a EudraCT protocol, of which   7290   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.

    General information about the trial
    Main objective of the trial
    To explore the pharmacodynamic (PD) effects, and specifically on occurrence and timing of ovulation with pregnancy risk, of ellaOne taken after pills of combined oral contraception (COC) were missed for three consecutive days during the first week of COC use and were resumed either on the day of ellaOne intake or five days later.
    Protection of trial subjects
    Subjects had to be withdrawn from study medication under the following circumstances: • Pregnancy (every attempt must be made to follow up subjects who become pregnant to determine the outcome of the pregnancy), • Serious intercurrent problems requiring admission to the critical care unit or surgery, • Subject unable to comply with study visits or requirements, • Suspected unexpected serious adverse reaction to study medication, • Subject withdraws informed consent, • Liver enzymes levels above three times the upper limit of normal at D1 or D15 of the EXP period, • Upon discretion of the investigator in the event of a protocol violation (inclusion/ exclusion criteria).

    Recruitment
    Recruitment details
    The screening period was performed within a maximum of 28 days before start of Baseline period. The Baseline period was performed after all screening assessments are checked by the investigator. The Baseline period was from D1 to D28. The randomization was performed at D29 (= V2: D1: 1st day of the Experimental period)

    Pre-assignment
    Screening details
    The women screened had a BMI <30.0 kg/m2, relied on a COC as their primary method of contraception for at least 2 cycles before they enter the baseline (B) period and were willing to continue with a COC for at least 1 cycle after end of experimental (EXP) period, must not be at risk of pregnancy and were willing to use condoms during the study.

    Protocol dated on 07 December 2017 included additional specific: - Monitoring of Liver function test : Laboratory safety parameters (ALAT, ASAT, GGT, ALP, total bilirubin) were measured in addition to the screening, the following visits, on Day 1 and Day 15 of the Experimental period and at End-of-Study visit. - Exclusion criteria related to liver function and global study termination rules: Subjects presenting with any of the following were not to be included in the study: Liver enzymes levels at the screening visit above three times the upper limit of normal or any other anomalies in safety labs recognized as clinically significant by the investigator.

    08 Nov 2017
    Following reports of liver injuries cases observed with chronic use of Esmya (UPA 5 mg indicated for pre-operative treatment as well as intermittent treatment of moderate to severe symptoms of uterine fibroids in adult women of reproductive age), the BfArM addressed HRA Pharma on 8 Nov 2017 a request for hearing before ordering withdrawal, revocation or suspension of approval of the clinical trial. BfArM also asked to stop recruiting any patients until clarification was made to what extent do these events influence the benefit-risk (B/R) assessment of ellaOne use and what measure should be taken to ensure safety of the patient. No patient had yet entered the study at time of BfArM request. Concomitantly an Article 20 safety referral procedure (EMEA/H/A-20/1460/C/2041/0043) was triggered by the EU Commission to review B/R of Esmya taking into consideration reports of liver injuries. Since no signal of liver injury were detected during the clinical development of UPA 30 mg in the emergency contraception indication and in post-marketing surveillance, HRA Pharma considered that the events reported with Esmya were not relevant for the single 30 mg dose administration and did not impact the B/R assessment of the ongoing trial. HRA suggested the BfArM to reconsider the suspension of this clinical trial and proposed revisions to the protocol (see section substantial protocol amendments, protocol dated 07 Dec 2017). This was considered acceptable by the BfArM who issued an authorisation letter on 18 Dec 2017. At the end of Article 20 safety referral procedure for Esmya, the EMA confirmed that “No cases of serious liver injury have been reported with ellaOne and there are no such concerns with this medicine at this time”.
