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   44339   clinical trials with a EudraCT protocol, of which   7369   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.1 Medical condition or disease under investigation
    E.1.1Medical condition(s) being investigated
    Polycystic ovary syndrome.
    MedDRA Classification
    E.1.3Condition being studied is a rare disease No
    E.2 Objective of the trial
    E.2.1Main objective of the trial
    The prinicpal research objective is to determine if the administration of the drug metformin to women with polycystic ovary syndrome who are undergoing IVF treatment following the short GnRH antagonist treatment protocol reduces the incidence of moderate to severe ovarian hyperstimulation syndrome (OHHS) (i.e. Does metformin reduce the risk of OHSS in this group?).
    E.2.2Secondary objectives of the trial
    The secondary objectives of the study are to determine if metformin co-treatment would also improve other IVF outcomes: 1. Does metformin co-treatment lead to more favourable stimulation characteristics, including lower total dose of FSH required for stimulation, number and qulaity of eggs produced, duration of stimulation? 2. Does metformin co-treatment improve the biochemical markers of polycystic ovary syndrome and ovarian hyperstimulation syndrome? 3. Does metformin co-treatment improve the number and quality of embryos developed in the IVF cycle? 4. Does metformin co-treatment improve the chances of getting pregnant with IVF treatment?
    E.2.3Trial contains a sub-study No
    E.3Principal inclusion criteria
    Women who will be invited to take part in this study would be subject to following inclusion criteria: •Women with a known diagnosis of PCOS (as defined by the Rotterdam ESHRE/ASRM sponsored PCOS consensus workshop group, 2004) •Women must have a normal follicular stimulating hormone (FSH) •Women must be 20-39 years of age •Women must have a BMI ≤ 35 •Pre-treatment inclusion criteria would include: oSerum testosterone < 5.0 nmol/l oNormal prolactin oNormal thyroid function tests oNormal renal, liver & haematological indices
    E.4Principal exclusion criteria
    Women who do not conform to the above criteria would be excluded from the study In addition to the above these specific exclusion criteria would apply: •Women on other oral-antidiabetic agents or blood-glucose lowering preparations. •Women taking phenprocoumon •Women taking antivirals such as didanosine, stavudine, tenofovir. •Women taking cimetidine •Women taking ketofen •Women who have radiological examinations using contrast media within the preceding 48 hours. •Women with renal or hepatic impairment •Women who have had a recent myocardial infarct •Women with known vitamin B12 deficiency
    E.5 End points
    E.5.1Primary end point(s)
    The aim of the proposed study would be to compare the stimulation characteristics, biochemical profiles and IVF-ET outcomes in women with PCOS undergoing IVF treatment following the standard short GNRH antagonist protocol for ovarian stimulation with or without metformin. Primary Outcome Measure: •Incidence of moderate and severe OHSS requiring hospitalisation within 6 weeks of the treatment cycle.

    Participants would receive metformin (or placebo) for the duration of their IVF treatment cycle. If the study demonstrates that metformin co-treatment in the short GnRH antagonist protocol reduces the incidence of ovarian hyperstimulation syndrome (or improves other IVF outcomes) then it will be offered in future IVF treatment cycles.
