Physiologic Monitoring of Antidepressant Response

NCT00792168 · Status: COMPLETED · Phase: PHASE4 · Type: INTERVENTIONAL · Enrollment: 38

Last updated 2025-12-22

No results posted yet for this study

Summary

Primary: to identify physiologic indicators of venlafaxine treatment response using quantitative EEG (QEEG) cordance, and to determine if cordance changes are specifically associated with response to venlafaxine;

Secondary: to determine if cordance changes early in the course (i.e., prior to improvement in clinical symptoms) of venlafaxine (or another antidepressant if venlafaxine is not clinically indicated for a particular patient) are predictive of later clinical response.

Conditions

Interventions

DRUG

venlafaxine (Effexor)

venlafaxine 37.5 mg. or placebo will be prepared by the UCLA Pharmacy for the initial phase of the study. For the open-label phase of the study, subjects will receive the medication and dosage that is clinically indicated by the subject's primary physician in the community. After a one-week placebo lead-in, subjects will be randomly assigned to receive one capsule of either venlafaxine or placebo, with the dosage increase every two days until subjects receive four capsules daily (subjects will achieve a dose 150 mg. of venlafaxine after 7 days). The first dose will be administered in the morning, with subsequent capsules added on a b.i.d. schedule
