We are carrying out a clinical trial with an investigational drug that is being developed for the treatment of uterine fibroids, i.e. benign tumours which develop in the uterus causing pelvic pain, pressure on other organs and heavy bleeding both during and between menstrual cycles. The study drug will be delivered intravaginally, through a ring-shaped device, and intends to regulate the activities of a hormone, known as progesterone, via its receptor in the uterus which should help to treat the symptoms of uterine fibroids. The results of this study will help us to plan for future clinical trials in patients.

Study summary
This study will be conducted at our clinical trials unit in London Bridge and will involve healthy pre-menopausal female volunteers aged 18-45.

You will need to attend 2 screening appointments within 59 days prior to admission. If successful, you will be required to attend our unit for 3 in-house stays of 3 days/2 nights each and 23 short outpatient visits.

  • Screening is available now. The date of your admission will be determined by your menstrual cycle and will be discussed at screening.
  • You will attend your first screening appointment at our London Bridge facility on Day 2-4 of your menstrual cycle.
  • Your second screening appointment will take place between days 10-18 of your menstrual cycle and will be with a gynaecologist based on Harley Street in London. If you are then placed onto the study you will see your gynaecologist regularly throughout the duration of the study. Travel costs will be covered separately for all visits to the gynaecologist.
  • If your screening appointments are successful you will be placed onto the study one month after your screening process has been completed.
