Endometriosis Clinical Trial

Official title: ROSE II: Pilot Study to Analyze Menstrual Blood to Predict Endometriosis

Status Enrolling by invitation

Clinical Trial Summary

This product will be used as a diagnostic test to screen for the likelihood of endometriosis in menstruating adults with symptoms suggestive of endometriosis. The purpose of the test will be to guide clinical decisions regarding: 1) whether to undergo diagnostic laparoscopy to confirm the presence of endometriosis (currently, the gold standard for diagnosing endometriosis) and/or 2) how to guide the choice of hormonal or other therapies to treat symptoms of endometriosis.

Clinical Trial Description

Endometriosis is a chronic, complex, and common gynecologic disorder characterized by the growth of endometrial-like tissues outside of the uterus that is accompanied by inflammation. One of the most frustrating problems for those with endometriosis is the long delay before being diagnosed, which can be up to 7-10 years. One of the reasons for this delay is that definitive diagnosis requires invasive surgery (Tomassetti et al, 2021 PMID: 34690084). There are no approved non-invasive methods for predicting endometriosis. This study will assess the analysis of fresh menstrual blood as a non-invasive predictor of endometriosis. This approach is based on the numerous reports documenting the differences in the endometrium of women with and without endometriosis; this endometrium is shed each month as menstrual blood which can be easily collected and analyzed. Through this prospective, non-interventional pilot study the investigators propose to collect and analyze menstrual blood from healthy controls without chronic symptoms of endometriosis and symptomatic women who have significant and chronic symptoms suggestive of endometriosis and are considered by their healthcare providers to be candidates for diagnostic laparoscopic surgery in the coming months (as part of their standard care). Menstrual blood from controls and symptomatic cases will be analyzed using single cell RNA-sequencing to develop a panel of biomarkers that can be developed into a screening test or diagnostic test for endometriosis.

The primary objectives of this study are to confirm the results of our recent single cell RNA sequencing (scRNA-Seq) analysis of menstrual effluent obtained from healthy controls vs. endometriosis (and symptomatic subjects) obtained through IRB 13-376 and to develop a screening/ diagnostic algorithm (menstrual global (MG) score) based on the data to be used to predict endometriosis in symptomatic patients.

The secondary objective is to assess the reproducibility of the scRNA-Sequencing data using menstrual blood collected across different menstrual cycles among a subset of controls and/or cases (symptomatic patients).

There are no existing commercially available products for the diagnostic analysis of cells or tissues present in menstrual effluent for endometriosis or any other condition. To our knowledge this is no commercially available product for predicting endometriosis using peripheral blood or other biological specimens (other than the analysis of ectopic endometriosis lesions themselves). Currently, definitive diagnosis of endometriosis requires laparoscopic surgery and pathological analysis of the removed ectopic lesions. ;
