Myriad Announces GeneSight® Psychotropic Results from a Large Prospective Trial in Patients with Major Depressive Disorder
GeneSight Demonstrated Statistically Significant Improvement in the Gold Standard Clinical Outcomes of Remission and Response
SALT LAKE CITY, Nov. 02, 2017 (GLOBE NEWSWIRE) — Assurex Health, a wholly-owned subsidiary of Myriad Genetics, Inc. (NASDAQ:MYGN), today announced positive results from a double-blind, multi-center, randomized controlled trial assessing the impact of the GeneSight® Psychotropic test (GeneSight) on psychiatric treatment response in 1,200 patients with major depressive disorder (MDD). GeneSight is the leading pharmacogenomic test to help guide medication selection for mental health disorders.
This was the largest ever pharmacogenomics depression trial and primarily assessed Hamilton Depression Rating Scale 17 (HAMD-17) scores from baseline to eight weeks in patients receiving GeneSight-guided therapy compared to those receiving treatment-as-usual. The study was designed to evaluate three key endpoints relative to HAMD-17 scores: remission (HAMD-17 score ≤7), response (HAMD-17 reduction >50%), and symptom reduction.
Patients receiving the GeneSight test achieved a clinically meaningful and statistically significant improvement in both remission rates (p<0.01) and response rates (p=0.01) at eight weeks compared to the treatment-as-usual group. In addition, patients who received the GeneSight test had a greater reduction in HAMD-17 scores after eight weeks, compared to the treatment-as-usual group, with the difference approaching statistical significance (p=0.1). Lastly, the improvement in remission, response, and symptoms continued throughout the 24-week study period, demonstrating the durability of the benefit through that period. The data will be submitted for presentation at the upcoming American Psychiatric Association’s (APA) annual meeting in May 2018.
“From a clinician’s perspective, better but not well is not good enough and significant improvements in response and remission are always the most-desired endpoints,” said John Greden, M.D., Founding Chair of the National Network of Depression Centers (NNDC). “We are eager to discuss complete results from this study as well as potential future applications of pharmacogenomics at the upcoming APA annual meeting in May 2018.”
“The robustness of the results are attributed to the unique algorithm developed by our scientists that appropriately weights and combines multiple pharmacogenetic factors impacting mental health medication efficacy,” said Bryan Dechairo, Ph.D., executive vice president of Clinical Development, Myriad Genetics. “Improving remission and response rates are key treatment goals of clinicians because they directly improve patients’ lives and reduce healthcare costs. These endpoints also align with payer goals, and we look forward to having those discussions in the coming months.”
About the study design
The study is a 24 week, double-blind, multi-center, randomized controlled trial that evaluated 1,200 patients with moderate or severe MDD to assess the impact of the GeneSight test on psychiatric treatment response [NCT02109939]. Patients were randomized in a 1:1 ratio to the study group (those receiving the GeneSight test) or the treatment-as-usual group. Assessments were completed at baseline and at 4, 8, 12, and 24 weeks, with patients and raters completely blinded at the 4 and 8 week time points. Unblinding occurred during week 12 of the study, when treatment-as-usual patients were allowed to switch to GeneSight-guided therapy for the remaining 12 weeks of the study.
Assurex Milestone Payments
The sole endpoint to trigger a clinical trial milestone payment to the former stockholders of Assurex was a statistically significant (p<0.05) greater reduction in HAMD-17 score from baseline to week eight of the study in the GeneSight arm compared to the treatment-as-usual arm. That clinical trial milestone payment will not be due because this endpoint did not achieve statistical significance in the entire study population. However, we continue to expect that a revenue growth milestone payment (calendar year 2017 revenue compared to calendar year 2016 revenue) will be paid to the former stockholders of Assurex in our fiscal third quarter.
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.
