WYETH REPORTS DESVENLAFAXINE SUCCINATE DATA

A A

Wyeth Pharmaceuticals has reported Phase III data and results from other studies concerning its investigational drug for major depressive disorder (MDD), desvenlafaxine succinate (DVS-233), a novel serotonin-norepinephrine reuptake inhibitor (SNRI).

Overall, the data results showed desvenlafaxine succinate significantly improved depressive symptoms in adult patients compared to placebo. In a separate study investigating QTc prolongation involving healthy adult female subjects, desvenlafaxine succinate 200 mg and 600 mg doses did not affect the QT interval at the study's primary endpoint at eight hours post dose. Studying a drug's effect on the QT interval is one of many methods used to help determine a drug's overall safety profile.
