ASTEROID 6: Uterine Fibroid Study

ASTEROID 6: Uterine Fibroid Study

Why is this study being done?

Uterine fibroids are benign uterine tumors or growths of uterine muscle that grow in a round ball in the uterus. The most common symptoms of uterine fibroids are excessive vaginal bleeding and pelvic discomfort. When these symptoms begin to have a negative impact on a woman's quality of life, many women seek treatment. One treatment option is a hysterectomy, or surgical removal of the uterus. Currently, hysterectomy is the only definitive treatment and eliminates the possibility of recurrence.

Often women desire to avoid surgery. Therefore, there is a great need for an effective medication suitable for long-term treatment of uterine fibroids. Therefore, OHSU Women's Health Research Unit is conducting a study to evaluate the safety and effectiveness of an investigational oral medication, Vilaprisan, at treating uterine fibroids compared to the standard treatment.


You may be eligible for this study if you:

  • Are at least 18 years of age
  • Are generally healthy
  • Have a diagnosis of uterine fibroids and/or have had surgical treatment for uterine fibroids within 3 months but have a high risk for recurrence.
  • Are suffering from symptoms of uterine fibroids such as heavy menstrual bleeding, pressure or pain in your lower abdomen


Qualified participants will be compensated up to $2,375 for time and travel during the 37 month study. Study participation involves 13 in person visits to the OHSU Marquam Hill campus clinic. Study participants will also be expected to complete an electronic daily diary.
