Early Prediction of Fluoxetine Response

Phase 4
Completed
Conditions
Major Depressive Disorder
Interventions
Registration Number
NCT01075529
Lead Sponsor
Kaohsiung Kai-Suan Psychiatric Hospital
Brief Summary

The purpose of this study is to identify what degree of symptom changes during the early weeks could be used to predict eventual nonresponse at week 6 among depressive inpatients taking fluoxetine.

Detailed Description

Patients with major depressive disorder will receive 20 mg/day of fluoxetine for six weeks. Symptom severity was assessed by the 17-item Hamilton Depression Rating Scale (HAMD-17) at weeks 0, 1, 2, 3, 4 and 6. Stable response is defined as a reduction of 50% or more of the HAMD-17 score at week 4 and week 6 of treatment. Receiver operating characteristic curve will be used to determine the cutoff point of the percentage of HAMD-17 score reduction between stable responders and nonresponders at weeks 1, 2, 3 and 4.
