Official title

DORADO - A Phase 3, Randomized, Double-Blind, Placebo-Controlled, Multi-Center, Parallel Group Study to Evaluate the Efficacy and Safety of Fixed Doses of Darusentan in Subjects With Resistant Systolic Hypertension Receiving Combination Therapy With Three or More Antihypertensive Drugs, Including a Diuretic (Protocol DAR-311)

Brief summary

Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.

This is a research study of a new experimental drug called darusentan. Darusentan is not currently approved by the U.S. Food and Drug Administration (FDA) for use in the United States, which means that a doctor cannot prescribe this drug. The purpose of this study is to determine if darusentan is effective in reducing systolic blood pressure in subjects with resistant systolic hypertension, despite treatment with full doses of three or more antihypertensive drugs, including a diuretic.
