ListOutcomeTime frameDescription
PrimaryChange From Baseline in Total Dysmenorrheal Score at Final EvaluationBaseline and up to 4 Cycles (28 days per cycle)
Total dysmenorrheal score was defined as sum of 2 sub-scores: severity of dysmenorrhea (none: 0, mild: 1, moderate: 2, severe: 3) and use of analgesics (none: 0, mild: 1, moderate: 2, severe: 3). Total possible best is 0, and total possible worst is 6. Note: used with permission of Nobelpharma Co., Ltd. from the phase 3 clinical study protocol (Prog Med 2005:25 (3):739-758) of IKH-01 in dysmenorrhea (associated with endometriosis) (Nobelpharma Co., Ltd.)
SecondaryChange From Baseline in Total Dysmenorrheal Score at Cycle 1 up to Cycle 4Baseline and up to 4 Cycles (28 days per cycle)
Total dysmenorrheal score was defined as sum of 2 sub-scores: severity of dysmenorrhea (none: 0, mild: 1, moderate: 2, severe: 3) and use of analgesics (none: 0, mild: 1, moderate: 2, severe: 3). Total possible best is 0, and total possible worst is 6.
SecondaryNumber of Participants With Severity of Lower Abdominal Pain During Menstruation at Cycle 4Cycle 4 (28 days per cycle)
Severity of lower abdominal pain during menstruation was rated as none (none), mild (can be easily tolerated), moderate (noticeable, but does not interfere with daily activities), or severe (interferes with daily activities).
SecondaryNumber of Participants With Severity of Low Back Pain During Menstruation at Cycle 4Cycle 4 (28 days per cycle)
Severity of low back pain during menstruation was rated as none (none), mild (can be easily tolerated), moderate (noticeable, but does not interfere with daily activities), or severe (interferes with daily activities).
SecondaryNumber of Participants With Severity of Headache During Menstruation at Cycle 4Cycle 4 (28 days per cycle)
Severity of headache during menstruation was rated as none (none), mild (can be easily tolerated), moderate (noticeable, but does not interfere with daily activities), or severe (interferes with daily activities).
SecondaryNumber of Participants With Severity of Nausea or Vomiting During Menstruation at Cycle 4Cycle 4 (28 days per cycle)
Severity of nausea or vomiting during menstruation was rated as none (none), mild (can be easily tolerated), moderate (noticeable, but does not interfere with daily activities), or severe (interferes with daily activities).
SecondaryNumber of Participants With Total Pelvic Pain Score at Times Other Than During Menstruation at Cycle 4Cycle 4 (28 days per cycle)Total pelvic pain score was defined as sum of 2 sub-scores: severity of dysmenorrhea and use of analgesics. Higher score means it is more severe. 0=None, 6=Severest.
SecondaryChange From Baseline in Visual Analogue Scale (VAS) for Dysmenorrhea at Times Other Than During Menstruation at Cycle 4From baseline up to Cycle 4 (28 days per cycle)VAS is an unmarked scale on a line 100 mm in length, indicating from 0 mm (no pain) to 100 mm (worst pain a participant has ever experienced).
SecondaryVisual Analogue Scale (VAS) for Pelvic Pain at Times Other Than During Menstruation at Cycle 4Cycle 4 (28 days per cycle)VAS is an unmarked scale on a line 100 mm in length, indicating from 0 mm (no pain) to 100 mm (worst pain a participant has ever experienced).
SecondaryChange From Baseline in Endometrial Thickness After 4-cycle TreatmentFrom baseline to Cycle 4 (28 days per cycle)
Endometrial thickness was measured via transvaginal ultrasound examination. The endometrium is the inner membrane of the uterus. During the menstrual cycle, the endometrium grows to a thick, blood vessel-rich, glandular tissue layer.
SecondaryNumber of Bleeding / Spotting EpisodesFor the first 90 days
Bleeding data were captured from the diary a participant recorded by herself. Bleeding is a genital bleeding. Spotting is a slight genital bleeding with participant's experience. An episode means a series of bleeding and/or spotting. The bleeding /spotting analyses are by intensity.
SecondaryNumber of Bleeding / Spotting DaysFor the first 90 days
Bleeding data were captured from the diary a participant recorded by herself. Bleeding is a genital bleeding. Spotting is a slight genital bleeding with participant's experience. The bleeding /spotting analyses are by intensity.
SecondaryParticipants With Withdrawal BleedingAt Cycle 4 (28 days per cycle)Withdrawal bleedings were defined as bleedings while a participant takes placebo tablets.
SecondaryParticipants With Intracyclic BleedingAt Cycle 4 (28 days per cycle)Intracyclic bleedings were defined as bleedings while a participant takes active drugs.
SecondaryParticipants With Non-heavy Intracyclic BleedingAt Cycle 4 (28 days per cycle)Non-heavy bleedings were defined as those other than heavy bleeding (less or normal bleeding).
SecondaryParticipants With Non-heavy Withdrawal BleedingAt Cycle 4 (28 dyas per cycle)Non-heavy bleedings were defined as those other than heavy bleeding (less or normal bleeding).
SecondaryChange From Baseline in Serum Carbohydrate Antigen-125 (CA125) After 4-cycle TreatmentFrom baseline to Cycle 4 (28 days per cycle)CA125 is a laboratory parameter giving an indication of having tumor, whose elevated levels that were defined by a lab suggest a potential tumor.
SecondaryChange From Baseline in Serum C-reactive Protein (CRP) After 4-cycle TreatmentFrom baseline to Cycle 4 (28 days per cycle)CRP is a laboratory parameter giving an indication of inflammation, whose elevated levels that were defined by a lab suggest a potential inflammation.
SecondaryChange From Baseline in Serum Estradiol Level After 4-cycle TreatmentFrom baseline to Cycle 4 (28 days per cycle)Estradiol is a predominant sex hormone that presents in female.
SecondaryChange From Baseline in Serum Progesterone Level at Cycle 4From baseline to Cycle 4 (28 days per cycle)Progesterone is a steroid hormone involving in the female menstrual cycle, pregnancy, etc.
