What is being measured
The primary outcome is the main question the study is designed to answer.
Percentage of Participants Meeting the Criteria for Responder
Percentage of responders, defined as participants who met the following conditions:
- Menstrual blood loss (MBL) volume < 80 mL during the Final Month (the last 28 days prior to and including the Reference Day, which is defined as the last visit date during the Treatment Period (last treatment visit date) or the last dose date if there are evaluable alkaline hematin data after the last treatment visit date and prior to or on the last dose date), and
- ≥ 50% reduction in MBL volume from Baseline to the Final Month.
Participants who prematurely discontinued study drug due to "lack of efficacy," "requires surgery or invasive intervention for treatment of uterine fibroids," or "adverse events" were considered non-responders regardless of whether she meets the two aforementioned responder criteria or not.
Measured: Final Month (the last 28 days prior to and including the Reference Day), up to Month 6
Secondary outcomes (6)
Change From Baseline in MBL Volume to the Final Month
Baseline MBL volume was defined as the mean of total MBL volume from all the qualified menstrual cycles during the Screening Period, in which the total MBL volume is from all validated and non-validated sanitary products and the MBL volume of validated sanitary products only (excluding non-validated sanitary products) was greater than 80 mL.
The Reference Day is defined as the last visit date during the Treatment Period (last treatment visit date) or the last dose date if there are evaluable alkaline hematin data after the last treatment visit date and prior to or on the last dose date.
Measured: Baseline and Final Month (the last 28 days prior to and including the Reference Day), up to Month 6
Percentage of Participants With Suppression of Bleeding at the Final Month
Suppression of bleeding is defined as having 0 days of bleeding (spotting is allowed) during the Final Month with the interval starting from Study Day 11.
The Reference Day is defined as the last visit date during the Treatment Period (last treatment visit date) or the last dose date if there are evaluable alkaline hematin data after the last treatment visit date and prior to or on the last dose date.
Measured: Final Month (the last 28 days prior to and including the Reference Day), up to Month 6
Change From Baseline in MBL Volume to Month 6
Baseline MBL volume was defined as the mean of total MBL volume from all the qualified menstrual cycles during the Screening Period, in which the total MBL volume is from all validated and non-validated sanitary products and the MBL volume of validated sanitary products only (excluding non-validated sanitary products) was greater than 80 mL.
Measured: Month 0 (Baseline), Month 6
Change From Baseline in MBL Volume to Month 3
Baseline MBL volume was defined as the mean of total MBL volume from all the qualified menstrual cycles during the Screening Period, in which the total MBL volume is from all validated and non-validated sanitary products and the MBL volume of validated sanitary products only (excluding non-validated sanitary products) was greater than 80 mL.
Measured: Month 0 (Baseline), Month 3
Percentage of Participants With Baseline Hemoglobin <= 10.5 g/dL Who Have an Increase in Hemoglobin > 2 g/dL at Month 6
Measured: Month 0 (Baseline), Month 6
Change From Baseline in MBL Volume to Month 1
Baseline MBL volume was defined as the mean of total MBL volume from all the qualified menstrual cycles during the Screening Period, in which the total MBL volume is from all validated and non-validated sanitary products and the MBL volume of validated sanitary products only (excluding non-validated sanitary products) was greater than 80 mL.
Measured: Month 0 (Baseline), Month 1

Primary outcome
Percentage of Participants Meeting the Criteria for Responder
Time frame: Final Month (the last 28 days prior to and including the Reference Day), up to Month 6
Percentage of responders, defined as participants who met the following conditions: * Menstrual blood loss (MBL) volume < 80 mL during the Final Month (the last 28 days prior to and including the Reference Day, which is defined as the last visit date during the Treatment Period (last treatment visit date) or the last dose date if there are evaluable alkaline hematin data after the last treatment visit date and prior to or on the last dose date), and * ≥ 50% reduction in MBL volume from Baseline to the Final Month. Participants who prematurely discontinued study drug due to "lack of efficacy," "requires surgery or invasive intervention for treatment of uterine fibroids," or "adverse events" were considered non-responders regardless of whether she meets the two aforementioned responder criteria or not.

Questions about this trial
What is this clinical trial studying?
A Phase 3 study testing Elagolix and Estradiol/Norethindrone Acetate in people with Uterine Fibroids and Heavy Menstrual Bleeding, run by AbbVie at 105 sites in 2 countries.
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 5 inclusion and 5 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: finished, as of the sponsor's last update on 13 Jul 2021. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 105 sites in United States, Canada. 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. Some participants in this study may receive a placebo. 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 3 studies compare the treatment with the current standard treatment or a placebo in a large group, to confirm how well it works and watch for side effects.
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 30 Jun 2020). 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 Meeting the Criteria for Responder (time frame: Final Month (the last 28 days prior to and including the Reference Day), up to Month 6). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
On the ClinicalTrials.gov record for NCT02691494, which also lists 6 linked publications.
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 13 Jul 2021.
