Clinical trials

The European Union Clinical Trials Register allows you to search for protocol and results information on:
  • interventional clinical trials that are conducted in the European Union (EU) and the European Economic Area (EEA);
  • clinical trials conducted outside the EU / EEA that are linked to European paediatric-medicine development.
  • Learn   more about the EU Clinical Trials Register   including the source of the information and the legal basis.


    The EU Clinical Trials Register currently displays   37995   clinical trials with a EudraCT protocol, of which   6234   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).
     
    Examples: Cancer AND drug name. Pneumonia AND sponsor name.

    General information about the trial
    Main objective of the trial
    Work-up studies (Studies 1&2): To gather preliminary safety and efficacy data from first-in-Heavy Menstrual Bleeding use of oral dexamethasone, in women suffering from objectively verified Heavy Menstrual Bleeding (HMB) Adaptive RCT (Study 3): To identify the optimal dose of oral dexamethasone for reduction of Heavy Menstrual Bleeding in women with objectively verified HMB.
    Protection of trial subjects
    Trial was carried out under Medicines for Human Use (Clinical Trials) Regulations and ICH GCP. Trial participants were supported throughout the trial by experienced research nurses and clinical researchers.

    Recruitment
    Recruitment details
    Recruitment to the adaptive randomised trial took place between 2014 and 2018. First patient was consented for screening on 29/01/2014, first patient randomised on 01/07/2014 and the last visit for last patient was on 29/03/2018.

    Pre-assignment
    Screening details
    Recruitment in Lothian (Scotland) via gynaecology outpatient clinics; family medicine; media advertising. Women aged 18 years or over; reporting regular 28-42 day menstrual cycles; complaining of Heavy Menstrual Bleeding; with measured volume of menstrual blood loss (MBL) across two screening cycles (menstrual periods) averaging ≥ 50mL.

    Blinding implementation details
    Computer-generated pseudo-random numbers were used to generate the randomised allocation sequence. A web-based randomisation system ensured the allocation sequence was concealed from researchers, clinical staff and participants. To maintain concealment, bulk supplies of placebo and Dexamethasone were held by hospital pharmacy who dispensed trial medication in bottles labelled with a unique randomisation number from the list provided by the Edinburgh clinical trials unit.

    Bayesian analysis of change in mean MBL: Dex 0.4mg [1]
    End point description
    Note: The comparison groups are each of the Dexamethasone doses versus placebo. So we report an endpoint for the comparison of each Dexamethasone dose versus placebo.
    End point type
    Primary
    End point timeframe
    Change in MBL between screening (mean of screening cycles 1 and 2) and mean of treatment cycles 2 and 3 (of 3) : average time period was 5 months
    Notes
    [1] - The end point is not reporting statistics for all the arms in the baseline period. It is expected all the baseline period arms will be reported on when providing values for an end point on the baseline period.
    Justification: The design used is a response-adaptive, double blind, parallel group, dose finding randomised controlled trial. A Bayesian approach was used to compare 6 doses of Dexamethasone to placebo. In order to fit our analyses with the EudraCT reporting system options we have to create endpoints for each comparison (eg 0.4mg Dexamethasone to placebo) and therefore cannot include all treatment arms within a single endpoint entry.

    Statistical analysis description
    The dose-response curve for the primary outcome was analysed using a Bayesian second order normal dynamic linear model (NDLM), which is flexible and requires few assumptions about the shape of the underlying dose-response curve. The model adjusted for the screening MBL measurements of each woman. For each Dexamethasone dose, a 95% credible interval was then calculated for the mean difference in MBL change (Dexamethasone minus placebo).

    Bayesian analysis of change in mean MBL: Dex 1.0mg
    Statistical analysis description
    The dose-response curve for the primary outcome was analysed using a Bayesian second order normal dynamic linear model (NDLM), which is flexible and requires few assumptions about the shape of the underlying dose-response curve. The model adjusted for the screening MBL measurements of each woman. For each Dexamethasone dose, a 95% credible interval was then calculated for the mean difference in MBL change (Dexamethasone minus placebo).

    The comparison groups are each of the Dexamethasone doses versus placebo. So we report an endpoint for the comparison of each Dexamethasone dose versus placebo.
    End point type
    Primary
    End point timeframe
    Change in MBL between screening (mean of screening cycles 1 and 2) and mean of treatment cycles 2 and 3 (of 3) : average time period was 5 months
    Notes
    [7] - The end point is not reporting statistics for all the arms in the baseline period. It is expected all the baseline period arms will be reported on when providing values for an end point on the baseline period.
    Justification: The design used is a response-adaptive, double blind, parallel group, dose finding randomised controlled trial. A Bayesian approach was used to compare 6 doses of Dexamethasone to placebo. In order to fit our analyses with the EudraCT reporting system options we have to create endpoints for each comparison (eg 0.4mg Dexamethasone to placebo) and therefore cannot include all treatment arms within a single endpoint entry.
