NCT03749629

Brief Summary

The overall goal of this study is to assess the effectiveness of a widely available and widely used combinatorial pharmacogenomic (PGx) test for the treatment of major depressive disorder. Pharmacogenomic tests use genetic information to guide medication treatment decisions. The tests inform clinicians and patients of potential gene-drug interactions by analyzing pharmacokinetic (PK) genes (how drugs are metabolized) as well as pharmacodynamic (PD) genes (how drugs work). While combinatorial PGx testing is attractive to clinicians, patients, healthcare systems, and insurers, limited data demonstrate that PGx testing will result in better outcomes compared to evidence-based guideline treatment. Therefore, the investigators will conduct a prospective randomized comparative effectiveness study of best practice guidelines plus combinatorial PGx-guided treatment versus best-practice guideline concordant treatment alone.

Outcome Measures

Primary Outcomes (1)

  • Well-being as assessed by the World Health Organization Well-Being Index (WHO-5)

    Hypothesis: Combinatorial PGx-guided treatment will be superior to best-practice guideline treatment to increase well-being The World Health Organization-5 Well-Being Index (WHO-5, primary outcome measure) is a brief 5-item self-report questionnaire consisting of positively-worded statements related to positive mood, vitality, and general interests over the prior two weeks. Item scores range from 0 (none of the time) to 5 (all of the time), resulting in a range of summary scores from 0 (poor well-being) to 25 (optimal well-being).

Study Arms (2)

CANMAT + GeneSight Psychotropic Test guided tx

ACTIVE COMPARATOR

Participant treatment will be guided by the Canadian Network for Mood and Anxiety Treatments (CANMAT) and the pharmacogenomic test GeneSight®. GeneSight® is a neuropsychiatric, combinatorial, PGx test that provides recommendations for psychotropic medications (antidepressants, mood stabilizers, hypnotics for insomnia, and antipsychotics) based on a patient's individual genetic profile.

Other: GeneSight Psychotropic testOther: Canadian Network for Mood and Anxiety Treatment (CANMAT) Best Practice Guidelines

CANMAT alone

PLACEBO COMPARATOR

Participant treatment will be guided by the Canadian Network for Mood and Anxiety Treatments (CANMAT) alone.

Other: Canadian Network for Mood and Anxiety Treatment (CANMAT) Best Practice Guidelines

Interventions

GeneSight® Psychotropic powered by CPGx® technology, the only test for depression reimbursable by Medicaid and Medicare. GeneSight® is a neuropsychiatric, combinatorial, PGx test that provides recommendations for psychotropic medications (antidepressants, mood stabilizers, hypnotics for insomnia, and antipsychotics) based on a patient's individual genetic profile.

Eligibility Criteria

Age18 Years - 65 Years
Sexall
Healthy VolunteersNo
Age GroupsAdult (18-64), Older Adult (65+)

You may qualify if:

  • Ability to give informed consent
  • Between the ages of 18-65
  • Diagnosed with Major Depressive Disorder (assessed by the Composite International
  • Diagnostic Interview Screening Scales (CIDI-SC))
  • Currently Depressed (PHQ 9 ≥10)

You may not qualify if:

  • Diagnosis of bipolar disorder or schizophrenia
  • Patients posing a serious suicidal risk and/or in need of immediate hospitalization as judged by the treating clinician
  • Has a general medical condition that is responsible for depressive symptoms or uses a medication responsible for depressive symptoms
  • Any medical contraindications for participants to take study medications
  • Patients with a history of hypothyroidism unless taking a stable dose of thyroid medication and asymptomatic or euthyroid for 6 months
  • Patients with significant unstable medical condition; life threatening disease; hepatic insufficiency (3X Upper Limit of Normal (ULN) for AST and/or ALT); liver transplant recipient; cirrhosis of the liver; need for therapies that may obscure the results of treatment and/or of the study; malignancy (except basal cell carcinoma) and/or chemotherapy within 1 year prior to screening
  • Those that alter the ability of the stomach/digestive lining to absorb nutrients are not. GeneSight is unable to account for absorption issues due to this reason at this time.)
  • Patients who self-report to be pregnant or lactating
