Exploring a Potential Blood Test to Diagnose Major Depressive Disorder

Completed

Conditions studied: Major Depressive Disorder

In brief

The purpose of this study is to develop a blood test for major depression and measure the effects of ziprasidone monotherapy on these markers. Specific Aim: Using a multiplex biomarker assay we will measure levels of 16 biomarkers in patients with MDD enrolled in this ancillary study (adjunct to study NCT00555997) and compare these results to those of healthy controls" (defined as research subjects who have not met criteria for any lifetime Axis-I disorder (DSM-IV)) from an existing dataset at PHB.

Age: 18 and older, up to 65. Sex: any. Healthy volunteers: not accepted.

You may qualify if…

• Age 18-65.

• Treatment with antidepressants for 2 weeks prior to the screen visit. If interested in discontinuing their current medication, potential participants must discuss this possibility with the prescribing physician. Study doctors will not implement any form of treatment washout.
• Patients who no longer meet DSM-IV criteria for MDD during the baseline visit, or patients who demonstrate a 25% or greater reduction in QIDS-SR scores, screening to baseline.
• Serious suicide or homicide risk, as assessed by the evaluating clinician or a score of 4 on the third item of the HAM-D.
• Unstable medical illness including cardiovascular, hepatic, renal, respiratory, endocrine, neurological, or hematological disease.
• Patients who meet criteria for alcohol or substance dependence, active within the last month.
• Any bipolar disorder (current or past).
• Any psychotic disorder (current or past).
• Psychotic features in the current episode or a history of psychotic features.
• History of a seizure disorder.
• Clinical or laboratory evidence of untreated hypothyroidism.
• Patients requiring excluded medications (see table 1 for details).
• Prior course of ziprasidone, or intolerance to ziprasidone at any dose.
• Any investigational psychotropic drug within the last 3 months.
• Patients with significant cardiac conduction problems on screening electrocardiogram such as atrial fibrillation, atrial flutter, atrio-ventricular block, prolonged or abnormal QTc interval (i.e. QTc>450msec), or prolonged QRS interval.
• Patients who have suffered a myocardial infarction within the past 12 months, with uncompensated heart failure, or a history of QTc prolongation.
• Patients with abnormal serum potassium or magnesium levels upon screening.
• Patients currently taking other drugs that prolong the QTc including dofetilide, sotalol, quinidine, class Ia antiarrhythmics, class III antiarrhythmics, mesoridazine, thioridazine, chlorpromazine, droperidol, pimozide, sparfloxacin, gatifloxacin, moxifloxacin, halofantrine, mefloquine, pentamidine, arsenic trioxide, levomethadyl acetate, dolasetron methylate, probucol or tacrolimus.
• Patients who have failed to experience significant clinical improvement following 3 or more antidepressant trials of adequate duration (at least 6 weeks) and dose (minimal effective doses defined as: fluoxetine, paroxetine, citalopram 20mg; sertraline, fluvoxamine 50mg, escitalopram 10mg, paroxetine CR 25mg, venlafaxine 75mg, duloxetine 60mg, bupropion 150mg, 15mg of mirtazapine, trazodone or nefazodone 300mg).
