What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Percentage of Participants in Amenorrhea

    Amenorrhea was defined as no bleeding intensity score greater than 1 using the Daily Diary Card during the 28 days leading up to the last day of dosing at Week 18. Bleeding intensity was graded on a 5-point scale where: 0=no bleeding to 4=heavy bleeding.

    Measured: At the end of 18 weeks Treatment Course 1

  2. Percentage Change From Baseline in Total Uterine Fibroid System Quality of Life Survey System Severity (UFS-SSS) Score

    UFS-SSS is an 8-question assessment tool used to measure symptom severity and has been validated as a three month look back questionnaire. Each question was answered on a 5-point scale where 1=Not at all to 5=A very great deal. The sum of the total scores was transformed to a range of 0=no symptoms (best) to 100=most severe symptoms (worst). A negative percentage change from Baseline indicates improvement.

    Measured: Baseline to the end of 18-weeks Treatment Course 1

  3. Percentage Change From Baseline in the Individual UFS-SSS Subscale Score Question 1

    UFS-SSS is an 8-question assessment tool used to measure symptom severity and has been validated as a three month look back questionnaire. The participant answered UFS-SSS subscale question 1: During the previous 3 months how distressed were you by "heavy bleeding during your menstrual period"? using a 5-point scale where 1=Not at all to 5=A very great deal. A negative percentage change from Baseline indicates improvement.

    Measured: Baseline to the end of 18-weeks Treatment Course 1

  4. Percentage Change From Baseline in the Individual UFS-SSS Subscale Score Question 2

    UFS-SSS is an 8-question assessment tool used to measure symptom severity and has been validated as a three month look back questionnaire. The participant answered UFS-SSS subscale question 2: During the previous 3 months how distressed were you by "passing blood clots during your menstrual period"? using a 5-point scale where 1=Not at all to 5=A very great deal. A negative percentage change from Baseline indicates improvement.

    Measured: Baseline to the end of 18-weeks Treatment Course 1

  5. Percentage Change From Baseline in the Individual UFS-SSS Subscale Score Question 3

    UFS-SSS is an 8-question assessment tool used to measure symptom severity and has been validated as a three month look back questionnaire. The participant answered UFS-SSS subscale question 3: During the previous 3 months how distressed were you by "fluctuation in the duration of your menstrual period compared to your previous cycle"? using a 5-point scale where 1=Not at all to 5=A very great deal. A negative percentage change from Baseline indicates improvement.

    Measured: Baseline to the end of 18-weeks Treatment Course 1

  6. Percentage Change From Baseline in the Individual UFS-SSS Subscale Score Question 4

    UFS-SSS is an 8-question assessment tool used to measure symptom severity and has been validated as a three month look back questionnaire. The participant answered UFS-SSS subscale question 4: During the previous 3 months how distressed were you by "fluctuation in the length of your monthly cycle compared to your previous cycles"? using a 5-point scale where 1=Not at all to 5=A very great deal. A negative percentage change from Baseline indicates improvement.

    Measured: Baseline to the end of 18-weeks Treatment Course 1

  7. Percentage Change From Baseline in the Individual UFS-SSS Subscale Score Question 5

    UFS-SSS is an 8-question assessment tool used to measure symptom severity and has been validated as a three month look back questionnaire. The participant answered UFS-SSS subscale question 5: During the previous 3 months how distressed were you by "feeling tightness or pressure in your pelvic area"? using a 5-point scale where 1=Not at all to 5=A very great deal. A negative percentage change from Baseline indicates improvement.

    Measured: Baseline to the end of 18-weeks Treatment Course 1

  8. Percentage Change From Baseline in the Individual UFS-SSS Subscale Score Question 6

    UFS-SSS is an 8-question assessment tool used to measure symptom severity and has been validated as a three month look back questionnaire. The participant answered UFS-SSS subscale question 6: During the previous 3 months how distressed were you by "frequent urination during the daytime hours"? using a 5-point scale where 1=Not at all to 5=A very great deal. A negative percentage change from Baseline indicates improvement.

    Measured: Baseline to the end of 18-weeks Treatment Course 1

  9. Percentage Change From Baseline in the Individual UFS-SSS Subscale Score Question 7

    UFS-SSS is an 8-question assessment tool used to measure symptom severity and has been validated as a three month look back questionnaire. The participant answered UFS-SSS subscale question 7: During the previous 3 months how distressed were you by "frequent night time urination"? using a 5-point scale where 1=Not at all to 5=A very great deal. A negative percentage change from Baseline indicates improvement.

    Measured: Baseline to the end of 18-weeks Treatment Course 1

  10. Percentage Change From Baseline in the Individual UFS-SSS Subscale Score Question 8

    UFS-SSS is an 8-question assessment tool used to measure symptom severity and has been validated as a three month look back questionnaire. The participant answered UFS-SSS subscale question 8: During the previous 3 months how distressed were you by "feeling fatigued"? using a 5-point scale where 1=Not at all to 5=A very great deal. A negative percentage change from Baseline indicates improvement.

    Measured: Baseline to the end of 18-weeks Treatment Course 1

  11. Change From Baseline in Pictorial Blood Loss Assessment Chart (PBAC) Score

    Uterine bleeding was assessed with the use of the PBAC, a validated self-reporting method to estimate menstrual blood loss. Participants recorded daily the number of tampons and towels used and the degree to which individual items were soiled with blood (plus small or large clots). Pictorial scores range from score 1 for slightly stained tampon/towel, 5 for a partially stained tampon/towel, 10 for a completely saturated tampon, 20 for a completely saturated towel, and 5 for each episode of flooding and for each blood clot larger than a quarter in size. Total score can range from 0 (no bleeding) to >500. Higher scores indicate more bleeding. Lower scores indicate less bleeding. A negative change from Baseline indicates improvement (reduction in bleeding).

    Measured: Baseline to the end of 18-weeks Treatment Course 1

  12. Percentage Change From Baseline in Total Uterine Fibroid Volume

    The total uterine fibroid volume was measured by Magnetic Resonance Imaging (MRI). A negative percentage change from Baseline indicates improvement.

    Measured: Baseline to the end of 18-weeks Treatment Course 1

Questions about this trial

What is this clinical trial studying?

A Phase 2 study testing Telapristone acetate in people with Uterine Fibroids, run by Repros Therapeutics Inc. at 8 sites in United States.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 7 inclusion and 16 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: stopped early, as of the sponsor's last update on 27 Jun 2019. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 8 sites in United States. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

What does this phase mean?

Phase 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

Are results available for this study?

Yes. Results are posted in the registry (first posted 19 Jun 2019). A summary is in the For doctors view, and the full results are on ClinicalTrials.gov.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Percentage of Participants in Amenorrhea (time frame: At the end of 18 weeks Treatment Course 1). The study lists 12 primary outcomes in all. It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 27 Jun 2019.
