[18F]FES PET/CT in PAH

Study Purpose

In this study positron emission tomography (PET/CT) imaging will be used to evaluate evaluation of estrogen receptor heterogeneity and functionality in Pulmonary Arterial Hypertension (PAH) using the investigational radiotracer [18F]fluoroestradiol (FES).

Recruitment Criteria

Accepts Healthy Volunteers

Healthy volunteers are participants who do not have a disease or condition, or related conditions or symptoms

No
Study Type

An interventional clinical study is where participants are assigned to receive one or more interventions (or no intervention) so that researchers can evaluate the effects of the interventions on biomedical or health-related outcomes.


An observational clinical study is where participants identified as belonging to study groups are assessed for biomedical or health outcomes.


Searching Both is inclusive of interventional and observational studies.

Trial Details

Trial ID:

This trial id was obtained from ClinicalTrials.gov, a service of the U.S. National Institutes of Health, providing information on publicly and privately supported clinical studies of human participants with locations in all 50 States and in 196 countries.

NCT02899533
Phase

Phase 1: Studies that emphasize safety and how the drug is metabolized and excreted in humans.

Phase 2: Studies that gather preliminary data on effectiveness (whether the drug works in people who have a certain disease or condition) and additional safety data.

Phase 3: Studies that gather more information about safety and effectiveness by studying different populations and different dosages and by using the drug in combination with other drugs.

Phase 4: Studies occurring after FDA has approved a drug for marketing, efficacy, or optimal use.

Pulmonary Arterial Hypertension
Additional Details

This is a feasibility study of serial FES scanning in female patients with Pulmonary Arterial Hypertension (PAH) to determine whether patients have detectable changes in FES SUV following treatment with fulvestrant on the separate therapeutic protocol IRB# 824861 "Estrogen Receptor Antagonist in Patients with Pulmonary Arterial Hypertension (ERA PAH)". Subjects will undergo up to 2 [18F]FES PET/CT scans for this protocol. A baseline FES PET/CT will occur on Day 0 (-2 days) of the companion treatment trial prior to initiation of fulvestrant. The second FES PET/CT scan will occur on week 9 (63 ± 7 days) after initiation of fulvestrant. We will compare SUV values after fulvestrant to pre-treatment values.
