About this study

WomEC is an in vitro diagnostic test for Endometrial Cancer (EC) based on the detection of the expression level of a combination of 5 proteins in the soluble fraction of a pipelle biopsy specimen. The aim of the study consists in validating WomEC's ELISA test, creating and freezing an algorithm to rule out EC in post-menopausal women with abnormal uterine bleeding (AUB).

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • WomECDiagnostic test

    The study will collect pipelle biopsies from post-menopausal women presenting with AUB entering to the EC diagnostic process at the clinical consultancy or emergency room. In the study an endometrial biopsy by aspiration will be collected (i.e., pipelle biopsy) and it will be used for (1) diagnostic purposes following current procedures (i.e., pathological examination and diagnosis); (2) placed in a collection tube for WomEC test.

Study groups in NCT06192017
Study groupRoleWhat they receive
Post-menopausal women with AUBThe patients will be divided into different study groups: "Control" and cases or "EC", the latter could be subdivided and analyzed in separate groups related to their prognosis. The "Control" patients are those patients with symptoms compatible with endometrial cancer but who are diagnosed with benign and / or healthy pathology; while "EC" patients present associated symptoms and are diagnosed with endometrial cancer.
Receives: Diagnostic Test: WomEC

What is being measured

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

  1. Regulatory Requirements Study

    Ensure the stability of the samples under defined conditions (pre-analytica) and the analytical validation of the developed WomEC's ELISA test.

    Measured: 12 months

  2. Algorithm training with Proprietary Antibodies

    Train the current WomEC's algorithms defined in MS by assessing the clinical performance of different EC biomarkers individually and in combination to rule out EC in post- menopausal women with AUB using MiMARK's proprietary antibodies.

    Measured: 12 months

  3. Algorithm testing and freeze

    To test and freeze the defined algorithm measured with MiMARK's antibodies to rule out EC in post-menopausal women with AUB.

    Measured: 12 months

Secondary outcomes (4)
  1. To determine the accuracy of WomEC alone for the diagnosis of EC by pipelle biopsy.

    Test the ability of WomEC to discriminate between EC and non-EC patients.

    Measured: 12 months

  2. Evaluation of the performance of different models of WomEC to determine histological subtype.

    Calculate the sensitivity, specificity, accuracy, precision, and clinical validity of WomEC to determine an histological subtype.

    Measured: 12 months

  3. Evaluation of the performance of WomEC to determine other prognostic factors of EC.

    Calculate the sensitivity, specificity, accuracy, precision, and clinical validity of WomEC to determine other prognostic factors of EC.

    Measured: 12 months

  4. Evaluation of the performance of WomEC to diagnose endometrial atypical hyperplasia.

    Calculate the sensitivity, specificity, accuracy, precision, and clinical validity of WomEC to diagnose endometrial atypical hyperplasia.

    Measured: 12 months

Questions about this trial

What is this clinical trial studying?

An observational study of Endometrium Cancer, run by MiMARK Diagnostics, S.L. at 26 sites in Spain.

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 2 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 28 Aug 2025. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 26 sites in Spain. 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.

Are results available for this study?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

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?

Regulatory Requirements Study (time frame: 12 months). The study lists 3 primary outcomes in all. 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 NCT06192017, which also lists 17 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 28 Aug 2025.
