NCT03749109

Brief Summary

This will be a randomized, double-blind, placebo-controlled, proof-of-mechanism phase 2 trial investigating the effect of quinagolide extended-release vaginal ring on reduction of lesions assessed by high-resolution magnetic resonance imaging in women with endometrioma, deep infiltrating endometriosis, and/or adenomyosis.

Outcome Measures

Primary Outcomes (1)

  • Changes in the Sizes (mm) of Endometrioma, Deep Infiltrating Endometriosis (DIE) and Adenomyosis Lesions Summed by Type on Magnetic Resonance (MR) Images at Cycle 4

    The MRI examination was performed on a high resolution 3T machine at screening and at end-of-treatment / cycle 4. At screening, every measurable lesion (defined as ≥10 mm in size) of any type was recorded and was summed up by type for primary analysis.

    At baseline and at menstrual cycle 4 (around 5 months, each cycle is approximately 28 days)

Secondary Outcomes (45)

  • Percentage of Changes in the Sizes of Endometrioma, DIE and Adenomyosis Lesions Summed by Type on MR Images at Cycle 4

    At baseline and at menstrual cycle 4 (around 5 months, each cycle is approximately 28 days)

  • Proportion of Lesions by Type With a Decrease in a Size of ≥5 mm on MR Images at Cycle 4

    At baseline and at menstrual cycle 4 (around 5 months, each cycle is approximately 28 days)

  • Proportion of Subjects With a Lesion of Any Type Decreased in a Size of ≥5 mm on MR Images at Cycle 4

    At baseline and at menstrual cycle 4 (around 5 months, each cycle is approximately 28 days)

  • Number of New or Disappearing Endometrioma, DIE and Adenomyosis Lesions Summed by Type on MR Images at Cycle 4

    At baseline and at menstrual cycle 4 (around 5 months, each cycle is approximately 28 days)

  • Changes in the Volumes (mm3) of Endometrioma and DIE Lesions Summed by Type on MR Images at Cycle 4

    At baseline and at menstrual cycle 4 (around 5 months, each cycle is approximately 28 days)

  • +40 more secondary outcomes

Eligibility Criteria

Age18 Years - 45 Years
Sexfemale(Gender-based eligibility)
Healthy VolunteersNo
Age GroupsAdult (18-64)

You may qualify if:

  • Pre-menopausal women between the ages 18-45 years (both inclusive) at the time of signing the informed consent
  • Body mass index (BMI) of 18-35 kg/m2 (both inclusive) at screening
  • Confirmation of deep infiltrating endometriosis (DIE), endometrioma or adenomyosis by high-resolution MRI at screening
  • Willing and able to use a non-hormonal single-barrier method (i.e. condom) for contraception from the start of screening to the end-of-treatment. This is not required if adequate contraception is achieved by vasectomy of the male sexual partner, surgical sterilisation (e.g. tubal ligation and blockage methods such as ESSURE) of the subject, or true abstinence of the subject (sporadic sexual intercourse with men requiring condom use)
  • Willing to avoid the use of vaginal douches or any other intravaginally administered medications or devices (except for tampons) from randomization to the end of treatment

You may not qualify if:

  • Use of depot medroxyprogesterone acetate (MPA) within 10 months prior to the screening visit.
  • Use of gonadotropin-releasing (GnRH) agonists (3-month depot) or dopamine agonists within 6 months prior to the screening visit.
  • Use of GnRH agonists (1-month depot or nasal spray), GnRH antagonists, aromatase inhibitors, danazol, birth control implants (e.g. NEXPLANON), progestogen or levonorgestrel releasing intrauterine device (IUD) within 3 months prior to the screening visit.
  • Use of hormonal contraceptives (including combined oral contraceptive pill, transdermal patch, and contraceptive ring) within 1 menstrual cycle prior to the screening visit.
  • Contraindications to MRI such as having internal/external metallic devices and/or accessories (e.g. cardiac pacemakers and leg braces)
