Depression Clinical Trial
Official title:
A Three-arm, Parallel Group, Multicentre, Double-blind, Randomized Controlled Trial Evaluating the Impact of GeneSight Psychotropic and Enhanced-GeneSight Psychotropic, on Response to Psychotropic Treatment in Outpatients Suffering From a Major Depressive Disorder (MDD) and Having Had - Within the Current Episode - an Inadequate Response to at Least One Psychotropic Medication Included in GeneSight Psychotropic

Evidence exists supporting the ability of genetic variations to influence patient drug response and side effects. Previous studies utilizing an open-label design have shown significant improvement in major depressive disorder (MDD) patient outcomes following use of the GeneSight Psychotropic (GEN) test. The first objective of this trial is to utilize a double-blinded, randomized clinical trial design to replicate previous findings of improvement in clinical outcomes in MDD subjects whose medication therapy was guided by GEN testing. Another objective is to determine the added benefit of Enhanced-GeneSight (E-GEN) compared to GEN for the pharmacogenomic guidance of treatment selections. Furthermore, this trial intends to develop an evidence-based case for the value of GEN and E-GEN to Canadian healthcare payers.

Eligibility |
Inclusion Criteria: - 18 years of age or older; - Suffer from a Major Depressive Episode meeting Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition, Text Revision (DSM-IV-TR) criteria; - Have had an inadequate response within the current episode to at least one psychotropic treatment in GEN. Inadequate response is defined as inadequate efficacy after 6 weeks of a psychotropic treatment or discontinuation of a psychotropic treatment due to adverse events (AEs) or intolerability; - Have each a score on the 16-item Clinician Quick Inventory of Depressive Symptomatology (QIDS-C16) and 16-item Self-Report Quick Inventory of Depressive Symptomatology (QIDS-SR16) rating scales = 11; - Be able to understand the requirements of the study and provide written informed consent to participate in this study; - Agree to abide by the study protocol and its restrictions and be able to complete all aspects of the study, including all visits and tests. Exclusion Criteria: - Patients posing a serious suicidal risk and/or in need of immediate hospitalization as judged by the Investigator; - Patients with a diagnosis of Bipolar I or II disorder; - Patients with a current Axis I diagnosis of: - Delirium - Dementia - Amnestic and/or other cognitive disorder - Schizophrenia or other psychotic disorder; - Patients having experienced hallucinations, delusions, or any psychotic symptomatology within the current depressive episode or during prior depressive episodes; - Patient is currently in an inpatient facility; - Patients with a history of hypothyroidism unless taking a stable dose of thyroid medication and asymptomatic or euthyroid for at least 6 months; - Patients who meet DSM-IV-TR criteria for any significant current substance use disorder; - Patients with: - hepatic insufficiency (three times the upper limit of normal (ULN) for aspartate aminotransferase (AST) and/or alanine aminotransferase (ALT)); liver transplant recipient; cirrhosis of the liver; - malignancy (except basal cell carcinoma) and/or chemotherapy within 1 year prior to screening; malignancy more than 1 year prior to screening must have been local and without metastasis and/or recurrence, and if treated with chemotherapy, without nervous system complications; - significant unstable medical condition or life threatening disease with - need for therapies that may obscure the results of treatment and/or of the study; - Participation in another clinical trial within 30 days of the screening visit; - Anticipated inability to attend scheduled study visits; - Patients who in the judgment of the Investigator may be unreliable or uncooperative with the evaluation procedure outlined in this protocol; - Patients with a history of prior pharmacogenomic testing; - Any change in psychotropic medication (including change in dosage) between screening and baseline; - Patients currently receiving electroconvulsive therapy (ECT), deep brain stimulation (DBS) or transcranial magnetic stimulation (TMS) treatments, or currently scheduled to receive maintenance treatments of ECT, DBS, or TMS during the course of the study; - Patients who self-report to be pregnant or lactating; - Patients with a history of gastric bypass surgery. |
