A Double Blind Randomized Controlled Trial to Assess the Efficacy and Safety of a Quadruple Ultra-low-dose Treatment for Hypertension (QUARTET USA)

Washington University School of Medicine·interventional·Posted Aug 21, 2018·Updated Jan 3, 2025

In Brief

A Phase 2 clinical trial evaluating QUARTET LDQT and Candesartan for Hypertension. Completed, enrolled 62 participants across 2 sites.

Detailed Summary

To investigate, in a double-blind randomized controlled trial, whether initiating treatment with ultra-low-dose quadruple-combination therapy ("LDQT") will lower office blood pressure more effectively, and with fewer side effects, compared to initiating standard dose monotherapy as per current guidelines in patients with hypertension. Primary hypothesis: A combination pill comprising four types of blood pressure lowering medications, each at one-quarter standard doses, will lower office blood pressure more effectively than initiating patients with standard dose monotherapy as per contemporary clinical practice guideline recommendations.
