Results Show that Primary Care Physicians Obtained Improved Outcomes for Patients with Depression When Medication Selection Is Guided by the GeneSight® Test

SALT LAKE CITY, July 25, 2018 (GLOBE NEWSWIRE) -- Myriad Genetics, Inc. (NASDAQ:MYGN), a worldwide leader in personalized medicine, today announced that results from the Individualized Medicine: Pharmacogenetics Assessment and Clinical Treatment (IMPACT) study were published in the Journal of Psychiatric Research.  The study evaluated 1,871 patients with moderate-to-severe depression who met the overall study criteria.  The goal of the study was to compare patient outcomes based upon ordering physician type in patients whose therapy selection was aided by the GeneSight® test.             

The study found that the outcomes were strong regardless of provider type, and the patients seen by primary care physicians actually improved the most.  Importantly, the patients treated by primary care physicians compared to psychiatrists saw 27 percent greater improvement in depressive symptoms, 35 percent higher rates of response, and 63 percent higher rates of remission (Table 1).

* The landmark GUIDED study was presented at the American Psychiatric Association annual meeting in May 2018. 

“The first physicians to typically treat patients with major depression are primary care physicians so it is critical that they have access to advanced technologies that can help patients as early as possible,” said Bryan M. Dechairo, Ph.D., executive vice president of Clinical Development at Myriad Genetics.  “The IMPACT study demonstrates that primary care physicians when aided by the GeneSight test can achieve excellent patient outcomes that were better than what was seen in the recent GUIDED prospective clinical study.”

About IMPACT  
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 Major Depressive Disorder
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 million adults in the United States had at least one major depressive episode in the past year and the World Health Organization (WHO) categorizes clinical depression as the world's leading cause of disability. 

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.
