Crescendo Bioscience Announces Results from a Meta-Analysis of Studies with Vectra® DA at the 2017 Annual European Congress of Rheumatology

SALT LAKE CITY, June 15, 2017 (GLOBE NEWSWIRE) -- Crescendo Bioscience, a wholly-owned subsidiary of Myriad Genetics, Inc. (NASDAQ:MYGN), today announced that new data from a meta-analysis of clinical studies and a registry demonstrating the ability of the Vectra® DA test to predict joint damage were presented at the European League Against Rheumatism (EULAR) meeting in Madrid, Spain.

The key finding is that high Vectra DA score is associated with significantly increased risk of joint damage progression in a variety of patients with rheumatoid arthritis (RA), including those treated with disease-modifying antirheumatic drugs (DMARDs), tumor necrosis factor-alpha inhibitors (TNFi) and abatacept.

“We are very excited to present a meta-analysis data from over 800 patients tested with the Vectra DA test, which shows our ongoing commitment to collaborate with academic researchers to advance the knowledge of Vectra DA and its utility in the management of rheumatoid arthritis,” said Elena Hitraya, M.D., Ph.D., chief medical officer, Crescendo Bioscience. “Importantly, this analysis confirms the consistency and robustness of the previous findings. This new information advances the understanding of the role of molecule biomarkers in RA and can help to facilitate the discussion on the role of biomarkers in RA treatment guidance.”

The data are highlighted below and the abstract is available online at: www.congress.eular.org/abstract_archive.cfm. Follow Vectra DA on Twitter via @VectraDA and Myriad via @MyriadGenetics to stay informed about meeting news and updates by using the hashtag #EULAR2017.

Vectra DA Poster Presentation
Title: High multi-biomarker disease activity score is associated with high risk of radiographic progression in six studies.
Presenter: Eric Sasso, M.D., Crescendo Bioscience.
Date: Thursday, June 15, 2017, 11:45–1:30 p.m. CEST.
Location: Poster THU0091.

The analysis evaluated data from six cohorts to establish the relationship between the Vectra DA score and risk for radiographic progression (RP). The studies included had more than 800 patients with rheumatoid arthritis (RA) who received conventional DMARDs alone or with adalimumab, infliximab or abatacept. Overall rates of RP were 10 to 26 percent. In each study, RP was most frequent among patients with a high vs. low/moderate Vectra DA score (>44 vs. ≤44). Patients with high Vectra DA scores, were 3.6 to 9.5 times as likely as patients with low Vectra scores to develop RP (P=0.002 to <0.0001). The data from this study are summarized in Table 1.

A meta-analysis of the Leiden, SWEFOT Year 1 and OPERA Year 1 studies, showed that patients with a high Vectra DA score were 5.1 times as likely to develop RP (P<0.0001). In comparison, patients were 1.4 times as likely to develop RP as measured by DAS28-CRP (P=0.23) and 1.6 times as likely as measured by CRP alone (P=0.01), underscoring the superior predictive power of Vectra DA compared with conventional assays (Graph 1).

“In this meta-analysis, the Vectra DA test has demonstrated the superior ability to predict joint damage compared with traditional measures such as DAS28-CRP or CRP, making Vectra DA an important tool in the management of patients with RA,” said Hitraya. “Importantly, Vectra DA also demonstrated clinical value by identifying patients with little or no risk of RP. We believe combining the Vectra DA score with conventional clinical measures will enable physicians to individualize treatment plans for their patients, improve outcomes and reduce the burden of future healthcare costs associated with this disabling disease.”

The efficacy of Vectra DA has been proven in more than 35 studies with more than 3,000 patients. The clinical utility for Vectra DA has been widely recognized as three out of four rheumatologists have used Vectra DA and have ordered it for more than 300,000 patients in the United States. Recently, Vectra DA was included in guidelines published by United Rheumatology and will be evaluated for inclusion in the American College of Rheumatology (ACR) guidelines. Additionally, Creaky Joints, a leading advocacy group for patients with RA added Vectra DA to its professional guidelines, which underscores the importance of Vectra DA to the patient community.
