New Studies Highlight Performance of Vectra® Test in Patients with Rheumatoid Arthritis Who Were Treated with Tofacitinib and Rituximab

Salt Lake City, Utah, UNITED STATES

Data Show Vectra Test Is Correlated with Treatment Response

SALT LAKE CITY, Oct. 19, 2018 (GLOBE NEWSWIRE) -- Myriad Genetics, Inc. (NASDAQ: MYGN), a global leader in personalized medicine, today announced new data from two studies of Vectra® that evaluated the test’s ability to track treatment response in patients with rheumatoid arthritis (RA).  The studies were conducted by academic collaborators and will be presented at the American College of Rheumatology meeting in Chicago, IL.  The key findings are that Vectra statistically significantly predicted response to tofacitinib and tracked response to rituximab.

“We are committed to advancing the knowledge of the Vectra test for rheumatologists and their patients with rheumatoid arthritis.  This year we are highlighting two new studies that demonstrate the performance of Vectra in patients treated with Ritaximab and Tofacitinib,” said Elena Hitraya, M.D., Ph.D., chief medical officer, Myriad Autoimmune.  “The goal is to provide rheumatologists with objective molecular information that can enable better patient management.”

Vectra is the leading personalized medicine test for patients with RA, and it is used to assess changes in disease activity.  In a recently presented analysis based on multiple studies, Vectra was shown to be three times more effective at predicting radiographic progression in patients with RA compared to other measures of disease activity. 

The key data are summarized below.  Please visit Myriad Autoimmune at Booth #321 to learn more about Vectra.  Follow Myriad on Twitter via @MyriadGenetics and @Vectra and stay informed about conference news and updates by using the hashtag #ACR18.

Title:  Baseline Power Doppler and MBDA Score Predicts 12 Week Disease Activity Response to Tofacitinib.
Presenter:  Amir Razmjou, M.D., UCLA-David Geffen School of Medicine, Los Angeles, Calif.
Date:  Sunday, Oct. 21, 2018, 9:00-11:00 a.m. CDT.   
Abstract Number: 582.

This is the first study to evaluate whether baseline Vectra scores were predictive of clinical response in 25 patients with RA who were treated with tofacitinib.  Vectra scores were assessed at baseline, 2 and 12 weeks.  The results show that the Vectra score at baseline was a statistically significant predictor of treatment responses to tofacitinib at week 12 (p<0.01).

Title:  The Multi-Biomarker Disease Activity Score Tracks Response to Rituximab Treatment in Rheumatoid Arthritis Patients.
Presenter:  Nadia MT Roodenrijs, Ph.D. candidate, University Medical Center Utrecht, the Netherlands.
Date:  Monday, Oct. 22, 2018, 9:00-11:00 a.m. CDT.   
Abstract Number: 1500.

This is the first study to demonstrate that the Vectra score tracked disease activity in RA patients treated with rituximab and that change in the Vectra score reflected the degree of treatment response.  The Vectra score was measured at baseline (n=57) and at 6 months (n=46).  The results show that the improvement in the Vectra score after 6 months was statistically significant (p<0.01), reflecting response to treatment with rituximab.

“We are excited about these new findings which advance the knowledge on Vectra,” said Hitraya.  “We’re committed to proving rheumatologists with valuable information about a patient’s disease activity that can help direct treatment strategies and improve patient outcomes.”

About Rheumatoid Arthritis
Rheumatoid arthritis is an autoimmune disease that mainly attacks the body’s joints, leading to significant morbidity and financial burden.  Approximately 60 percent of people with inadequately treated RA are unable to work 10 years after onset.  The American College of Rheumatology estimates that RA affects 1.3 million people in the United States.

About Vectra 
Vectra is a multi-biomarker molecular blood test that provides an objective and personalized measure of inflammatory disease activity in patients with rheumatoid arthritis. Vectra demonstrates unsurpassed ability to predict radiographic progression and guides medical management decisions to improve patient outcomes.  Vectra testing is performed at a state-of-the-art CLIA (Clinical Laboratory Improvement Amendments) facility.  Test results are reported to the physician five to seven days from shipping of the specimen. Physicians can receive test results by fax or the private web portal, VectraView. For more information on Vectra, please visit:
