Descriptive Information
Brief Title † [18F]FES PET/CT in PAH
Official Title † [18F]Fluoroestradiol (FES) PET/CT Imaging To Evaluate In Vivo ER In Patients With Pulmonary Arterial Hypertension
Brief Summary 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).
Detailed Description 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.
