BACKGROUNDUterine Fibroids (also called Uterine leiomyomas or myomas) are common benign tumors of the myometrium, which are reported to occur in approximately 30-40% of all women of reproductive age. They may remain asymptomatic, or cause bleeding abnormalities and/or bulk-related symptoms depending on their number, size and location. Various medications are used for symptom-oriented therapy in minor disease (e.g. combined oral contraceptives, progestogens, iron supplements). For short-term therapy and/or as a precursor to surgery, gonadotropin-releasing hormone agonists represent the most effective medical treatment. However, their use is restricted to 6 months due to hypo-estrogenic side effects. For definite treatment of symptomatic leiomyomas, therapeutic options are mainly surgical so far. Uterine Fibroids are the leading cause for hysterectomy. Hysterectomy is at present time the only definitive treatment and eliminates the possibility of recurrence.
Various studies suggested steroid-dependence of fibroids growth in which progesterone has a critical role. This is supported by the fact, that Progesterone Receptor (PR) antagonists—like mifepristone (RU 486)—have been shown to decrease the size of fibroids and related symptoms. Therefore, PR antagonists might offer a promising therapeutic alternative meeting the need for medical long-term treatment of symptomatic fibroids with an orally effective agent lacking clinically relevant side effects. Mifepristone (RU 486) was disclosed in EP057115.
Spitz et al. Current Opinion in Obstetrics and Gynecology, 2009, 21:318-324 discloses compounds being effective in the treatment of Uterine Fibroids where that are associated with a reduction in pain and bleeding and improvement in quality of life and decrease in fibroids size. Long-term treatments are associated with endometrial thickening confirmed by ultrasound and histological changes of the endometrium. The endometrial change such as endometrial thickening seems to be connected to cystic glandular dilatation.
Progesterone receptor antagonists with a fluorinated 17α-side chain were published in WO 98/34947 and Fuhrmann et al., J. Med. Chem. 43, 5010-5016 (2000).
In PEARL I and PEARL II trial (N Engl J Med. 2012;366:409-420) women with excessive uterine bleeding due to the presence of fibroids were randomized to ulipristal acetate (5 mg vs. 10 mg orally once daily) vs. placebo or intramuscular injections of leuprolide acetate for up to 13 weeks.
WO2009/134178 discloses methods for treating endometrial proliferation wherein progesterone antagonists is used such as CDB-4124 in a six-month treatment regimen. Unfortunately, administration of a relatively low concentration of CDB-4124 results in a substantial thickening of the endometrium during treatment.
WO2004/098517 discloses a regimen in which a female is administered a combined dosage form of estrogen and progestin for more than 50 consecutive days.

Compound 1 is a potent Selective Progesterone Receptor Modulator (SPRM) and more particularly a competitive Progesterone Receptor (PR) antagonist creating alternatives for the treatment of Uterine Fibroids. Amenorrhea was observed in healthy subjects treated with compound 1 that was originally disclosed in WO2011/009531A1. Amenorrhea corresponds to the major objective of the treatment i.e. control of excessive uterine bleeding. It has been surprisingly found that long term treatment with Compound 1 is safe for patient in need. Indeed, amenorrhea was observed at early stage and with high intensity Further, ovulation inhibition was observed, pelvic pain was found to be reduced, no endometrial hypertrophy was reported (TEAE), and uterine fibroids size was clearly reduced.

First biopsy: Biopsy during the screening period:
The first endometrial biopsy was performed on Day 9+/−2 of the first or second menstrual cycle after screening visit 1, i.e. at screening visit 2.
Second biopsy: Biopsy was determined by randomization. This means that subjects were randomized to the time point of the second biopsy and were informed about the group they are in, directly after randomization followed by stratification by dose group. Each subject had a biopsy at one of the following 4 time points: between Week 8 and Week 12 of treatment.
If a subject was randomized to this time point, the biopsy was scheduled on Day 9+/−2 of the first menstrual cycle after the treatment visit 2 (corresponding to Visit 5), i.e. during the last 4 weeks of study drug treatment. If no menstrual bleeding occurs between the treatment visit 2 (Visit 5) and the end of treatment (EoT) visit (Visit 6), the biopsy was performed at the end of treatment (EoT) visit (Visit 6).
Following the First Menstrual Bleeding After the End of Treatment:
If a subject was randomized to this time point, the biopsy was scheduled on Day 9+/−2 of the first menstrual cycle after the end of treatment. If no menstrual bleeding occurs until 12 weeks after end of treatment, i.e. until the follow-up visit 2 (Visit 8), a biopsy was performed at the follow-up visit 2 (Visit 8) and induction of bleeding was considered.
Following the Second Menstrual Bleeding After the End of Treatment:
If a subject was randomized to this time point, the biopsy was scheduled on Day 9+/−2 of the second menstrual cycle after the end of treatment. If no menstrual bleeding occurs until 12 weeks after end of treatment, i.e. until the follow-up visit 2 (Visit 8), a biopsy was performed at the follow-up visit 2 (Visit 8) and induction of bleeding was considered.
Following the Third Menstrual Bleeding After the End of Treatment:
If a subject is randomized to this time point, the biopsy was scheduled on Day 9+/−2 of the third menstrual cycle after end of treatment. If no menstrual bleeding occurred until 12 weeks after end of treatment, i.e. until the follow-up visit 2 (Visit 8), a biopsy was performed at the follow-up visit 2 (Visit 8) and induction of bleeding was considered.
Third biopsy: At the end of follow-up, i.e. 21 to 24 weeks after end of treatment.
The third endometrial biopsy was performed at the follow-up visit 3 (Visit 9), which was scheduled on Day 9+/−2 of the menstrual cycle which started following Week 20 after the end of treatment. If no bleeding episode occurred, Visit 9 was performed 24 weeks after end of treatment, i.e. Visit 9 took place 21 to 24 weeks after the end of treatment in all subjects. If the second endometrial biopsy was performed less than 6 weeks before the scheduled date of the third endometrial biopsy and pathological findings were absent, the third endometrial biopsy was not required.
In certain situations, unscheduled endometrial biopsies should be performed in addition.
Treatment Period:
Eligible subjects were equally randomized to one of the treatment groups (Placebo, 0.5 mg, 1 mg, 2 mg, or 4 mg Compound 1). Treatment started during the first week of the menstrual cycle following randomization. The treatment period consisted of 12 weeks (84 days) of daily tablet intake.
Follow-Up Period:
After the end of treatment, subjects were followed up for 21 to 24 weeks (Follow-up period). If spontaneous menstrual bleeding did not occur until 12 weeks after the end of treatment, an additional transvaginal ultrasound (TVU) and endometrial biopsy was performed followed by induction of bleeding, if indicated. In case of findings that require further follow-up, additional visits were scheduled according to normal standard practice.
EoT: End of Treatment visit
FUP1, 2, 3: Follow-up visit 1, 2, 3
RND: Randomization visit
SCR1, 2: Screening visit 1, 2
T1, 2: Treatment visit 1, 2
Efficacy Measurement:
-
- endometrial biopsies
- cervical smear
- transvaginal ultrasound TVU (endometrial thickness, ovaries)
Subjects that were detected with endometrial thickness (double layer) >18 mm (or suspicious bleeding pattern, e.g. continuous spotting, unusually heavy bleeding), were immediately evaluated by an additional endometrial biopsy.
Results:
Under treatment, no clear trend for an increase in endometrial thickness was observed. Endometrial thickness was measured after 3 months treatment, see table 1. At the end of follow-up, endometrial biopsies demonstrated benign endometrial histology changes (PAEC) and were reported in all available samples. It was no cases of hyperplasia.
Consequently, No treatment-emergent critical endometrial findings occurred.
Additionally, PAECs (progesterone receptor modulator associated endometrial changes) returned to background level during follow-up,

Women, 18 to 50 years old, with uterine fibroids documented by transvaginal or abdominal ultrasound at screening with at least 1 uterine fibroid with largest diameter 3 cm and Heavy Menstrual Bleeding (HMB) 80 ml were eligible for enrolment in the study.
Number of Women: 279 subjects
Screening Period:
Following screening visit 1 (Visit 1), there was a screening period of up to 90 days to arrange for complete results of all baseline assessments. During the screening period, subjects were to demonstrate eligibility including presence of at least 1 uterine fibroid of maximum 3 cm diameter and a diagnosis of HMB, defined as menstrual blood loss 80 ml assessed by menstrual pictogram (MP) during the bleeding episode following the screening visit 1 (Visit 1). Every effort should be made to keep the duration of the screening period to a minimum.
Treatment Period:
Eligible subjects were equally randomized to one of the treatment groups (Placebo, 0.5 mg, 1 mg, 2 mg, or 4 mg Compound 1). Treatment was started during the first week of the menstrual cycle following randomization. The treatment period consisted of 12 weeks (84 days) of daily tablet intake.
Efficacy Measurement:
-
- daily documentation of bleeding intensity (electronic diary or eDiary)
- Menstrual Pictogram MP (electronic diary or eDiary)

EXAMPLE 8 Change in Volume of Largest Fibroid 3-Month Treatment with Compound 1A randomized, parallel-group, double-blind, placebo-controlled, multi-center study to assess efficacy of different doses of Compound 1 where secondary efficacy variable is the change in volume of the largest fibroid in subjects wherein treatment is of 3 months [1×12 weeks (84 days)].
Study Protocol (N° 15788):
Test drug: Compound 1
Doses: 0.5 mg, 1 mg, 2 mg, or 4 mg once daily
Route of administration: Oral
Duration of treatment: 1×12 weeks (84 days)
Reference drug: Placebo
Duration of treatment: 1×12 weeks (84 days)
Diagnosis and main criteria for inclusion:
Women, 18 to 50 years old, with uterine fibroids documented by transvaginal or abdominal ultrasound at screening with at least 1 uterine fibroid with largest diameter 3 cm and heavy menstrual bleeding (HMB) 80 ml were be eligible for enrolment in the study.
Number of Women: 279 subjects
Screening period: as described in example 4
Treatment period: as described in example 4
Efficacy Measurement:
The secondary efficacy variable is the percent change in volume of the largest fibroid compared to baseline (measured by MRI and TVU)
-
- MRI: Magnetic Resonance Imaging
- TVU: Transvaginal/abdominal ultrasound
Transvaginal/Abdominal Ultrasound:
Ultrasound examination was performed consistent with the schedule of procedures (Table 1). For each subject, the most appropriate ultrasound method (transvaginal or abdominal) was used depending on fibroid location and this method was consistently used throughout the study. The same ultrasound machine (per site) should be used throughout the study.
The 3 largest fibroids were identified during the screening period. The largest transverse, longitudinal, and antero-posterior diameters of these 3 fibroids were documented at each ultrasound examination for volume calculation.
The dimensions of the uterus were also documented at the same time points. This is of particular importance in subjects with multiple small fibroids.
Magnetic Resonance Imaging:
Pelvic MRI was performed for volume measurements of the uterus and fibroids at the specified time points in all subjects (see table 1). A pelvic MRI without contrast agent administration was performed with a good diagnostic quality preferably on Tesla scanners. Images were sent to the dedicated Imaging Core Laboratory for further evaluation. Volume measurements of the uterus and fibroids were performed centrally by independent radiologist(s).
Results:
Compound 1 has demonstrated dose-dependent reduction in fibroid size during treatment. The effect is confirmed by both methods i.e. MRI and TVU. Effect is partially sustained during follow-up, see
