Endometriosis Biomarker Discovery Study (EMBARK)

August 31, 2017 updated by: Myriad Genetic Laboratories, Inc.

A Prospective Sample Collection Study in Patients With Pelvic Pain Undergoing Laparoscopy for Biomarker Identification in Endometriosis

This is a prospective, Single time point, discovery study intending to identify biomarkers that can differentiate endometriosis from other underlying reasons for pelvic pain. Patients undergoing laparoscopy for evaluation of chronic pelvic pain or elective tubal ligation will be enrolled for collection of tissue samples at the time of laparoscopy.

Study Overview

Status

Status

Indicates the current recruitment status or the expanded access status.
Withdrawn

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Detailed Description

This study will be a prospective collection of blood, urine, and endometrial tissue from women with chronic pelvic pain symptoms, with or without infertility, who require evaluation by laparoscopy. Women undergoing laparoscopy for elective tubal ligation will also be investigated similarly and serve as the negative control. Subjects will be queried regarding sociodemographic characteristics, medical and reproductive history, pain and lifestyle as well as assessment for differential diagnoses such as interstitial cystitis and idiopathic bowel syndrome. Endometriosis severity will be captured by rASRM staging during laparoscopy.

Study Type

Study Type

Describes the nature of a clinical study. Study types include interventional studies (also called clinical trials), observational studies (including patient registries), and expanded access.
Observational

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

18 years to 45 years (ADULT)

Accepts Healthy Volunteers

No

Genders Eligible for Study

Female

Sampling Method

Non-Probability Sample

Study Population

Women seeking care at OB/GYN clinics and fertility centers

Description

Inclusion Criteria:

  1. Able to give informed consent.
  2. Aged 18-45 years old who has a regular menstrual cycle (26 to 32 days in length).
  3. Undergoing a planned diagnostic or therapeutic laparoscopy for the indication of pelvic pain or for elective tubal ligation.
  4. One prior pregnancy for tubal ligation patients.

Exclusion Criteria:

  1. Prior surgical diagnosis of endometriosis.
  2. Currently pregnant or breastfeeding.
  3. Clinical suspicion of pelvic inflammatory disease (PID) or urinary tract infection.
  4. Current malignancy except non-melanoma skin cancer adequately treated.
  5. Known major systemic disease, including but not limited to inflammatory disease, autoimmune disease.
  6. Use of immunosuppressants in the past 3 months.
  7. Use of injectable reproductive hormonal therapy within the past 3 months and have not menstruated since last dose.
  8. If reproductive hormonal implant has been used in the past, it must have been removed > 3 months prior to study entry and subject must have menstruated since removal.
  9. Use of intrauterine device (IUD) in the past 3 months.
  10. Use of any other reproductive hormone therapy within the past 3 months, except for oral contraceptives (OCPs).

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
The identification of biomarker(s) that are differentially expressed in endometriosis in the context of pelvic pain
Time Frame: Baseline (pre-operative)
The primary variables will be the DiscoveryMAP analytes identified in blood and/or urine and the mRNA transcriptome in endometrial tissue. DiscoveryMAP is a comprehensive, quantitative platform of immunoassays evaluating multiple analytes in various body system categories: cytokines, chemokines, metabolic markers, hormones, growth factors, tissue remodeling proteins, angiogenesis markers, acute phase reactants, and cancer markers
Baseline (pre-operative)

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Measure Description
Time Frame
The identification of biomarker(s) that are associated with endometriosis severity
Time Frame: Baseline (pre-operative)
The secondary variables will be measures of endometriosis severity: rASRM staging of endometriosis and pain severity from clinical survey
Baseline (pre-operative)

Study record dates

These dates track the progress of study record and summary results submissions to ClinicalTrials.gov. Study records and reported results are reviewed by the National Library of Medicine (NLM) to make sure they meet specific quality control standards before being posted on the public website.

Study Major Dates

Study Start

Study Start

The actual date on which the first participant was enrolled in a clinical study. The "anticipated" study start date is the date that the researchers think will be the study start date.
September 1, 2016

Primary Completion (ANTICIPATED)

Primary Completion

The date on which the last participant in a clinical study was examined or received an intervention to collect final data for the primary outcome measure. Whether the clinical study ended according to the protocol or was terminated does not affect this date. For clinical studies with more than one primary outcome measure with different completion dates, this term refers to the date on which data collection is completed for all the primary outcome measures. The "anticipated" primary completion date is the date that the researchers think will be the primary completion date for the study.

Study Completion (ANTICIPATED)

Study Completion

The date on which the last participant in a clinical study was examined or received an intervention/treatment to collect final data for the primary outcome measures, secondary outcome measures, and adverse events (that is, the last participant's last visit). The "anticipated" study completion date is the date that the researchers think will be the study completion date.
