NCT05480995

Brief Summary

Purpose: The aim of this study is to assess the sensitivity and specificity of FFNP PET/MRI for diagnosis of endometriosis. Participants: A total of 24 participants will be recruited from individuals with clinically suspected endometriosis. Procedures (methods): This is a prospective, one arm, single center study of 24 subjects with clinically suspected endometriosis to demonstrate FFNP PET-MRI's clinical utility for diagnosis of endometriosis.

Outcome Measures

Primary Outcomes (2)

  • Sensitivity of 18F-fluorofuranylnorprogesterone (FFNP) PET/MR for evaluating endometriosis

    The sensitivity of FFNP PET /MR is defined as the ability of readers (radiologists) to correctly detect endometriosis in patients who have endometriosis.

    Upon completion of all study image data collection for all participants [approximately 1 year]

  • Specificity of 18F-fluorofuranylnorprogesterone (FFNP) PET/MR for evaluating endometriosis

    The specificity is similarly defined as the ability of readers to exclude endometriosis in patients who do not have it.

    Upon completion of all study image data collection for all participants [approximately 1 year]

Secondary Outcomes (3)

  • Diagnostic accuracy of PET /MRI

    Upon completion of all study image data collection for all participants [approximately 1 year]

  • Correlation of uptake values (SUV-max) with Endometriosis Health Profile (EHP-30) scale controlling for covariates

    Upon completion of all study image data collection for all participants [approximately 1 year]

  • Correlation of uptake values (SUV-max) with pain level using a visual analog scale (VAS) controlling for covariates

    Upon completion of all study image data collection for all participants [approximately 1 year]

Study Arms (1)

18F-fluorofuranylnorprogesterone PET / MRI

EXPERIMENTAL

All enrolled subjects will receive the tracer and then have a PET/MRI scan.

Drug: 18F-fluorofuranylnorprogesterone PET / MRI

Interventions

Subjects will receive a PET/MRI with 18F-fluorofuranylnorprogesterone tracer

18F-fluorofuranylnorprogesterone PET / MRI

Eligibility Criteria

Age18 Years - 55 Years
Sexfemale(Gender-based eligibility)
Gender Eligibility DetailsSubjects must be assigned the gender of female at birth.
Healthy VolunteersNo
Age GroupsAdult (18-64)

You may qualify if:

  • Age 18 or older
  • Female of childbearing age (18-55 years)
  • Clinically suspected (symptomatic) endometriosis as defined by referring physician (this would also include endometriomas as other disease may be present).
  • Scheduled for planned operative laparoscopy with no hormone treatment for at least two cycles
  • Able to provide informed consent

You may not qualify if:

  • Male
  • Institutionalized subject (prisoner or nursing home patient)
  • Known history of breast, ovarian or endometrial cancer.
  • Pregnant or breast-feeding women
  • Chronic progestin-containing medications or Gonadotropin-releasing hormone (GnRH) analogues in the last 10-16 days (or 2 cycles in the case of GnRH analogues as these are dosed monthly) or inability to discontinue these medications
  • Allergy to gadolinium contrast or Glomerular Filtration Rate (GFR) below 30 ml/min.
