About the DEVA study


We are looking for women to join our study and help us find out whether a new antiseptic treatment, dequalinium chloride, is as good at treating bacterial vaginosis (BV) symptoms (such as an unpleasant smell or discharge) as antibiotics.

Joining the study is easy and free and you can take part without leaving the house. To get involved you need to:

  • Complete the expression of interest form (pink button at the top of this page) and let us know the best time to call you.

  • We send you everything you need to be part of the trial, including study information and and a vaginal sample kit (by post) to check if you have BV.

  • If you do have BV and join the trial, we will post out your treatment for free, along with a second sample kit to check if your treatment has worked.

  • Four and 12 weeks after you start treatment, we will ask you to answer some questions about your symptoms. To say thanks, we will send you £15 of Amazon vouchers (£10 at week 4 and £5 at week 12).

For more information, watch the below video.
