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   43851   clinical trials with a EudraCT protocol, of which   7283   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 ).

    General information about the trial
    Main objective of the trial
    The aim of the feasibility study is to find out if an appropriately powered randomised controlled trial can be realistically undertaken. The feasibility study will also allow the research team to identify any barriers to recruitment and compliance, and fine tune study procedures such as data collection and prescription of the study treatments. The aim of the definitive study would be to test the hypothesis that vaginal oestrogen treatment of postmenopausal women undergoing pelvic floor repair surgery leads to improved patient reported outcomes in relation to urinary, bowel, sexual function and prolapse related quality of life (QoL). Feasibility study specific objectives: 1.To obtain estimates for important aspects of the protocol to allow development of a definitive trial 2.To derive real- time data on the design aspects of the study I.Proportion of eligible women of those screened II.Proportion of eligible women randomised III.Attrition rates IV.Compliance with treatment
    Protection of trial subjects
    We ensure that all staff are GCP trained and will only grant access to allow staff at site to become involved in the trial if their GCP is in date. It is imperative that all investigators and staff at the sites have a thorough understanding of anticipated adverse events and the reporting process of these events as it is their responsibility to notify adverse events and SAE's to the Trial Office and for the Sponsor, or designated delegate, to report to the regulatory authority and ethics committee. For each SAE, the following information will be collected, from the gynaecologist, treating doctor or woman herself. SmPC updates are checked monthly and any changes circulated to sites and pharmacy. The patient Information Sheet contained the details of the Patient Advice and Liaison Service (PALS) for the individual sites.
    Background therapy
    Prolapse may be associated with weakening or atrophy of the genital tract. Oestrogen deficiency secondary to menopause results in weakening of the supporting ligaments of the pelvic organs and the pelvic floor muscles worsening the symptoms of prolapse. The vagina also contains oestrogen receptors and is sensitive to changes in circulating levels of oestrogen. Low oestradiol levels after the menopause lead to reduced vascularity of the tissues, along with a decrease in the glycogen content of epithelial cells. This in turn, leads to a fall in lactobacilli content and an increase in pH, encouraging the growth of certain bacteria, including coliforms. 9This may lead to overcolonization of the vagina, irritation and discharge. A decrease in oestrogen levels also results in atrophy of the vaginal epithelium, with more parabasal cells and fewer superficial cells seen on cytology. Associated symptoms include vaginal dryness, soreness, dyspareunia, dysuria or urinary urgency. Oestrogen treatment can be used to reduce thinning of the vaginal and pelvic tissues. This may help to reduce or prevent the symptoms of prolapse, or may be used to make other prolapse treatments work better. The different preparations of topical hormone replacement therapy (HRT) (creams, pessaries, tablets and the estradiol vaginal ring all appear equally effective for treating vaginal atrophy but the evidence on their effectiveness in reducing symptoms related to prolapse or indeed reducing the risk of recurrence of prolapse postoperatively is non-existent.
    Evidence for comparator
    Participants will be randomised individually into the study in an equal 1:1 ratio. A 'minimisation' procedure using a computer-based algorithm will be used to avoid chance imbalances in important stratification variables. Multicentre feasibility open label trial comparing vaginal low-dose oestrogen with no treatment, in 100 consenting postmenopausal women who are planning to undergo POP surgery. They will be randomly allocated to: Intervention group (Group A): This will comprise of 6 weeks course of oestradiol 10 μg preoperatively per vaginum (once daily for 2 weeks followed by twice weekly for four weeks) and then 10μg oestradiol per vaginum twice weekly from 6-26 weeks postoperatively. Comparison group (Group B) will receive no vaginal oestrogen treatment

    Recruitment
    Recruitment details
    100 women were recruited to the trial between July 2015 to August 2016. Women were recruited from six UK centres with equal numbers in both the pessary group and the no treatment group.

    Pre-assignment
    Screening details
    The trial approached 325 women with a POP and wanting surgery and were screened for eligibility, with 157 found to be eligible . Of these screened 100 women were randomised over a 13-month period (July 2015 to August 2016). Of the 100 randomised women, 85 ultimately had surgery. Of the other 15, 6 could not have surgery due to health issues.
