  • Having moderate to severe endometriosis-related pain.
  • Willing to use a non-hormonal barrier method (i.e. condom) for contraception from randomization to the end-of-trial. This is not required if adequate contraception is achieved by vasectomy of the sexual partner or surgical sterilisation of the subject.
  • Willing to avoid the use of vaginal douches or any other intravaginally administered medications or devices from randomization to the end of treatment.

  • Use of gonadotropin releasing hormone (GnRH) agonists (3 months depot) or dopamine agonists within 6 months of the start of run-in.
  • Use of GnRH agonists (1 month depot) or intrauterine device within 3 months of the start of run-in.
  • Use of GnRH antagonist, combined oral contraceptive pill or progestin-only pill within 1 month of the start of run-in.
