New Studies Demonstrate the Predictive Value of the Vectra® Test in People Diagnosed with Rheumatoid Arthritis

Vectra Test Predicts Radiographic Progression and CV Risks Associated with Inflammation

SALT LAKE CITY, Nov. 09, 2019 (GLOBE NEWSWIRE) — Myriad Genetics, Inc. (NASDAQ: MYGN), a global leader in precision medicine, announced that its Myriad Autoimmune business unit will present new data on the Vectra test at the 2019 ACR/ARP Annual Meeting being held Nov. 8-13, 2019 in Atlanta, GA.  The key findings are that the Vectra test predicts the risk of radiographic progression (RP) within one year, and the Vectra score, in combination with other clinical measures, predicts the risk of a cardiovascular (CV) event in people with rheumatoid arthritis (RA).

“A hallmark feature of rheumatoid arthritis is inflammation, which increases the risk of joint damage, cardiovascular disease and other comorbidities,” said Elena Hitraya, M.D., Ph.D., rheumatologist and chief medical officer at Myriad Autoimmune. “The data being presented by our academic collaborators at ACR show that the Vectra test accurately measures inflammation and can help predict patients’ risk of adverse health outcomes, enabling clinicians to tailor precision treatment plans to achieve better outcomes.”

Title: Predicting Risk of Radiographic Progression for Patients with Rheumatoid Arthritis.

This study evaluated the ability of the Vectra test to predict patients’ “individual percentage risk” of RP within one year. The analysis included combined data from 973 patients in four cohorts. The results demonstrate that the adjusted Vectra score was a superior predictor of RP within one year compared to DAS28-CRP, CRP, CDAI and swollen joint count. Additionally, the risk of permanent joint damage increased continuously with the adjusted Vectra score, meaning patients with a low adjusted Vectra score had a one to three percent risk of RP in one year, while patients with a moderate-to-high score had between seven and 47 percent risk (Graph 1). Based on these new data, the company is working to enhance the Vectra test report to provide patients with their “individual risk” of radiographic progression in one year.

“Too often people with RA are over- or under-treated because it is difficult for clinicians to accurately measure inflammation and determine the long-term prognosis of RA patients. As a result, some people are at increased risk of rapid radiographic progression,” said Jeff Curtis, M.D., M.S., MPH, lead investigator, rheumatologist and Professor of medicine in the Division of Clinical Immunology and Rheumatology at the University of Alabama at Birmingham. “It is critical that clinicians have reliable information when making treatment decisions. Our study demonstrated that the Vectra score was the strongest predictor of radiographic progression, which may help inform treatment plans and prevent future joint damage.”

Title: Derivation and Validation of a Biomarker-Based Cardiovascular Risk Prediction Score in Rheumatoid Arthritis.
Presenter: Jeff Curtis, M.D., M.S., MPH; University of Alabama at Birmingham.

Location: Poster 2350.

This study evaluated 30,751 Medicare patients with RA to develop and validate the Vectra CVD score, which predicts risk for a first cardiovascular (CV) event by combining data from Vectra and clinical measures. The primary CV outcome was a composite of three types of CV events – heart attack, stroke, and CV death – occurring within 3 years from testing. When the performance of the Vectra CVD score was compared to four other CV prediction models, the Vectra CVD score was a significant predictor of CV risk and was superior to all four other models. Importantly, when risk scores were converted to 3-year percentage risk for having a CV event, approximately 80 percent of patients were found to have a moderate or high risk of a CV event over 3 years, based on risk categories analogous to those of the American College of Cardiology/American Heart Association 2018 guidelines (Graph 2).

“People with rheumatoid arthritis have almost double the risk of heart attack, stroke and atherosclerosis. Traditional CV risk factors alone do not fully explain the increased rates of CV events in RA, and inflammation is a missing component that is measured by the Vectra test,” said Dr. Curtis. “In this study, the Vectra CVD score effectively predicted CV risk in people with RA. We believe the Vectra CVD score may assist clinicians to more quickly identify patients at high risk for CV events and target interventions that can be potentially life-saving.”

The company plans to publish these new data in peer reviewed medical journal and make the Vectra CVD score available to clinicians in fiscal year 2020.
