The American College of Rheumatology Includes the Vectra® Test in New Recommendations on Disease Activity Measures for Rheumatoid Arthritis

SALT LAKE CITY, Nov. 20, 2019 – Myriad Genetics, Inc. (NASDAQ: MYGN), a global leader in molecular diagnostics and precision medicine, announced that the American College of Rheumatology (ACR) has included the Vectra® test in its new recommendations on disease activity measures for patients with rheumatoid arthritis (RA). The new recommendations were published in the journal Arthritis Care & Research .

The publication titled “ 2019 Update of the American College of Rheumatology Recommended Rheumatoid Arthritis Disease Activity Measures ” states that the Vectra test is among 11 disease activity measures that met a minimum standard by categorizing into disease activity states and being feasible for regular clinical use, and that Vectra was one of the five most frequently studied RA disease activity measures among 46 evaluated. Currently, there are more than 35 peer-reviewed Vectra journal publications.

“We are excited that the Vectra test has been included in the ACR’s recommendations for disease activity meaures. It will provide physicians with an additional option to evaluate their patients with RA,” said Elena Hitraya, M.D., Ph.D., chief medical officer, Myriad Autoimmune. “Vectra objectively measures the inflammation associated with RA and can provide valuable information to help clinicians improve treatment decisions and outcomes for patients with RA .”

Three out of four rheumatologists have used Vectra and have ordered more than 900,000 tests for their patients. The Vectra test previously was evaluated and included in clinical guidelines issued by United Rheumatology and in the clinical algorithm of Bendcare, two of the large rheumatology organizations in the United States.

RA is an autoimmune disease that attacks the patient’s joints and often affects other organ systems, leading to significant morbidity, increased mortality and financial burden. Approximately 60 percent of people with inadequately treated RA are unable to work by a decade after its onset. The American College of Rheumatology estimates that RA affects 1.5 million people in the United States.
