The SAPPHIRE Study (Systolic And Pulse Pressure Hemodynamic Improvement By Restoring Elasticity)

Summary

The purpose of this study is to evaluate the safety and efficacy of ALT-711 in the treatment of isolated systolic hypertension in a formal dose-ranging study in patients without left ventricular hypertrophy. Eligible patients will be randomized to double-blind treatment once daily for 6 months with oral ALT-711 (35, 70, 140, or 210 mg) or placebo.
