Intervention / Treatment
Detailed Description
There is increasing evidence approving role of medical therapy in treatment of symptomatic uterine fibroid, in the context of women's desire to preserve fertility or not to undergo operation.
Among these hormonal therapies, ulipristal acetate (UPA) is an orally administered selective progesterone receptor modulator commonly prescribed for treatment of uterine fibroid. This agent acts on causing apoptosis of the muscle cells inside the tumor and reducing the tumor matrix in case of uterine fibroid.
UPA at daily dose of 5 mg has been shown to decrease menstrual blood loss and reduce tumor size after 13 consecutive weeks of treatment.

What is the study measuring?
Primary Outcome Measures
Outcome Measure |
Measure Description |
Time Frame |
---|---|---|
Amenorrhea
Time Frame: from first dose to the end of 3 consecutive months of treatment course
|
Percentage of subjects achieve amenorrhea at the end of treatment.
Amenorrhea is defined of 35 consecutive non-bleeding days, in which spotting is accepted.
|
from first dose to the end of 3 consecutive months of treatment course
|
Secondary Outcome Measures
Outcome Measure |
Measure Description |
Time Frame |
---|---|---|
time from treatment to amenorrhea
Time Frame: from first dose to the end of 3 consecutive months of treatment course
|
the number of days from treatment initiation to the date that the subject has achieved amenorrhea.
|
from first dose to the end of 3 consecutive months of treatment course
|
uterine fibroid size change
Time Frame: from first dose to the end of 3 consecutive months of treatment course
|
the total volume of the 3 largest uterine fibroids will be measured.
Uterine fibroid size change will be calculated by percentage of the figure at the end of treatment in comparison to at baseline.
|
from first dose to the end of 3 consecutive months of treatment course
|
pelvic pain control
Time Frame: from first dose to the end of 3 consecutive months of treatment course
|
Pelvic pain assessed by visual analogue score (VAS).
The minimum score is 0, which means no pain at all.
The maximum score is 10, which means unbearable pain.
Higher scores mean worse outcome.
|
from first dose to the end of 3 consecutive months of treatment course
|
adverse events
Time Frame: from first dose to the end of 3 consecutive months of treatment course, and the end of 3 months follow-up without treatment
|
Percentage of participants have adverse events.
Adverse events are defined as any undesirable experience occurring to a subject during a clinical trial, whether or not considered related to the intervention
|
from first dose to the end of 3 consecutive months of treatment course, and the end of 3 months follow-up without treatment
|
Uterine fibroid symptom and health - related quality of life score change
Time Frame: from first dose to the end of 3 consecutive months of treatment course
|
Uterine Fibroid symptom and health - related quality of life questionnaire (UFS-QOL) consists of 37 questions to assess symptoms of uterine fibroid and their impacts on women's quality of life.
Each answer is scored from 1 to 5, in which 1 equals not at all and 5 equals all of the time.
The minimum score is 0 and the maximum score is 185.
Higher scores mean worse outcome.
|
from first dose to the end of 3 consecutive months of treatment course
|
Abnormal endometrial features and thickness
Time Frame: from first dose to the end of 3 consecutive months of treatment course
|
Endometrial thickness is assessed via transvaginal ultrasound every month after initiation of treatment.
Endometrial biopsy is performed at baseline and at the end of treatment.
|
from first dose to the end of 3 consecutive months of treatment course
|
abnormal liver function test findings
Time Frame: from first dose to the end of 3 consecutive months of treatment course
|
Liver enzym (AST, ALT) is assessed every month after initiation of treatment.
A two-fold or more increase in level of liver enzym is abnormal.
|
from first dose to the end of 3 consecutive months of treatment course
