Condition(s) targeted: Pulmonary Arterial Hypertension

Intervention: Anastrozole (Drug); Placebo (Drug)

Phase: Phase 2

Status: Active, not recruiting

Sponsored by: University of Pennsylvania

Official(s) and/or principal investigator(s):
Steven M Kawut, MD, MS, Principal Investigator, Affiliation: University of Pennsylvania


The main purpose of this clinical trial is to study the safety and efficacy of anastrozole in adults diagnosed with pulmonary arterial hypertension (PAH). The study will evaluate how well the drug is tolerated. The study will also evaluate if anastrozole effects estradiol (E2) hormone levels, a sex hormone, and improves the function of the lower right chamber of the heart (right ventricle).

Clinical Details

Official title: A Double-blind, Placebo-controlled Phase II Study of Anastrozole in Patients With Pulmonary Arterial Hypertension

Study design: Allocation: Randomized, Endpoint Classification: Safety/Efficacy Study, Intervention Model: Parallel Assignment, Masking: Double Blind (Subject, Caregiver, Investigator), Primary Purpose: Treatment

Primary outcome:

To assess the effects of anastrozole vs. placebo on the plasma estradiol (E2)level

To assess the effects of anastrozole vs. placebo on tricuspid annular plane systolic excursion (TAPSE)


Minimum age: 18 Years. Maximum age: N/A. Gender(s): Both.
