A Study in Relapse Prevention of Treatment-resistant Depression

2014-08-27 03:20:03 | BioPortfolio


The purpose of this study is to determine whether olanzapine and fluoxetine combination (OFC) if used for a long time (47 weeks) makes patients suffering from Treatment Resistant Depression stable, determine if OFC is safe when used to treat patients with Treatment Resistant Depression for a long time (up to 47 weeks), to determine whether olanzapine and fluoxetine combination or fluoxetine alone is better to treat Treatment Resistant Depression when treated for a long time ( up to 47 weeks) and to assess the quality of life during treatment.


This is a multicenter, randomized, double-blind, active comparator-controlled, parallel study of patients with Treatment Resistant Depression (TRD), comparing the efficacy and safety of olanzapine and fluoxetine Combination (OFC) versus fluoxetine in relapse prevention of stabilized patients with TRD. The study will consist of 4 phases: a screening phase; a 6- to 8-week open-label acute treatment phase; a 10- to 12-week open-label stabilization phase; and a 27- to 29-week double-blind relapse prevention treatment phase. Patients who demonstrate response to open-label OFC during the acute treatment phase will continue into the stabilization phase. Patients who remain stable while receiving open-label OFC during this phase will be randomized to receive either OFC or fluoxetine during the double-blind relapse prevention phase. Investigators and patients will be blinded to the precise duration of the stabilization period, the definition of remission, and the criteria for entry into the relapse prevention phase; this information is described in a supplement given to Ethical Review Boards (ERBs) and regulatory authorities.

Decompression external to the body, most often the slow lessening of external pressure on the whole body (especially in caisson workers, deep sea divers, and persons who ascend to great heights) to prevent DECOMPRESSION SICKNESS. It includes also sudden accidental decompression, but not surgical (local) decompression or decompression applied through body openings.

Depression in POSTPARTUM WOMEN, usually within four weeks after giving birth (PARTURITION). The degree of depression ranges from mild transient depression to neurotic or psychotic depressive disorders. (From DSM-IV, p386)

A propylamine formed from the cyclization of the side chain of amphetamine.
