GeneSight® Guided Treatment Significantly Improves Outcomes for Patients with Major Depression Treated in the Primary Care Setting

New Results from the IMPACT Study to be Presented at the American Society of Clinical Psychopharmacology (ASCP) Annual Meeting

SALT LAKE CITY, May 31, 2018 (GLOBE NEWSWIRE) — Assurex Health, a wholly-owned subsidiary of Myriad Genetics, Inc. (NASDAQ:MYGN), today announced that results from the Individualized Medicine: Pharmacogenetics Assessment and Clinical Treatment (IMPACT) study will be highlighted at the 2018 ASCP annual meeting in Miami Beach, Fla. 

The key finding is that patients with depression whose medication selection was guided by the GeneSight® Psychotropic genetic test saw improvements in remission, response and symptoms when treated by both primary care physicians and psychiatrists.  Additionally, patients treated by primary care physicians exhibited 33 percent more symptom improvement, 34 percent increased response and 57 percent greater remission than those treated by psychiatrists. 

“Most patients with depression are treated by primary care providers who select antidepressant medications using a trial and error approach,” said Bryan Dechairo, Ph.D., executive vice president of Clinical Development, Myriad Genetics.  “The IMPACT study demonstrated the clinical value of the GeneSight test to guide medication selection in the primary care setting and achieve better outcomes for patients.”

Title:  Pharmacogenomics and Depression Symptom Improvement: Treatment by Primary Care Physicians or Psychiatrists.
Presenter:  Julie-Anne Tanner, Ph.D., Assurex Health and Centre for Addiction and Mental Health.
Date:  Thursday, May 31, 2018, 12:30 – 2:00 p.m. EDT.   
Location:  Poster T24.

This study evaluated the clinical utility of the GeneSight test in selecting medications for 2,025 patients with moderate-to-severe major depressive disorder who were enrolled in the IMPACT study.  All patients were assessed using the Beck Depression Inventory (BDI) at baseline (Day 0) and follow up (Week 8-12) to measure symptom improvement, response and remission.  The findings were reported according to provider type (i.e., primary care vs. psychiatrist).

The overall results demonstrated that when clinicians used the GeneSight test results to guide medication selection, patients saw a 28 percent mean reduction in symptoms (p<0.01).  Additionally, 26 percent of patients responded to treatment and 17 percent achieved remission, which is consistent with previously reported studies.  Importantly, there were significantly greater improvements for patients treated by primary care providers versus psychiatrists (Graph 1).  Specifically, there was a 33 percent improvement in symptoms (p<0.01), 34 percent improvement in response (p<0.01) and 57 percent improvement in remission (p<0.01).

“In this study, the pharmacogenetic testing helped both psychiatrists and primary care providers achieve better outcomes for their patients, and the greatest improvements were observed in the primary care setting,” said James L. Kennedy, M.D., lead investigator and head of the Tanenbaum Centre for Pharmacogenetics at the Centre for Addiction and Mental Health in Toronto.  “The significant factor in these differences across care settings may be that psychiatrists frequently care for more complex patients who may have more difficult to treat depression. Importantly, these results strongly support expanding the use of pharmacogenetic testing to patients who are treated by primary care providers.”

The IMPACT study results are consistent with a landmark GeneSight study presented earlier this month at the American Psychiatric Association annual meeting in New York City.  That study showed that GeneSight guided therapy resulted in a 50 percent improvement in remission and a 30 percent improvement in response versus treatment as usual at week 8.    

Individualized Medicine: Pharmacogenetic Assessment & Clinical Treatment (IMPACT) is a research study conducted by the Tanenbaum Centre for Pharmacogenetics at the Centre for Addiction and Mental Health (CAMH), which uses the GeneSight genetic test to determine specific enzymes and genes related to medication action.  The goal of this research study is to achieve more effective therapies by incorporating genetic information.

About Depression
Major depressive disorder (MDD) is one of the most common mental disorders and can result in severe impairments that interfere with or limit one’s ability to carry out major life activities.  MDD is defined as a period of two weeks or longer during which there is either depressed mood or loss of interest or pleasure, and at least four other symptoms that reflect a change in functioning, such as problems with sleep, eating, energy, concentration, self-image or recurrent thoughts of death or suicide.  The National Institute of Mental Health estimates that more than 16.2 million adults in the United States had at least one major depressive episode in the past year. 

About GeneSight
GeneSight is a laboratory-developed pharmacogenomic test that uses cutting edge technology to measure and analyze clinically important genomic variants in the treatment of psychiatric disorders. The results of the GeneSight report can help a clinician understand the way a patient’s unique genomic makeup may affect certain psychiatric drugs. The analysis is based on pharmacogenomics, the study of genomic factors that influence an individual’s response to drug treatments, manufacturers’ FDA approved drug labels, peer reviewed scientific and clinical publications, and proven drug pharmacology.  Quick turnaround time, combined with a customized report of the patient’s genomic makeup, clinical experience, and other factors can provide information to help a physician make personalized drug treatment choices for each patient.
