Crescendo Bioscience Announces That New Studies With Vectra(R) DA Data Will be Presented at the American College of Rheumatology 2015 Annual Meeting

SALT LAKE CITY, Nov. 7, 2015 (GLOBE NEWSWIRE) — Crescendo Bioscience, a wholly-owned subsidiary of Myriad Genetics, Inc. (NASDAQ:MYGN), today announced that new data on the use of Vectra DA to predict treatment response in patients with rheumatoid arthritis (RA) are being presented at the American College of Rheumatology/Association of Rheumatology Health Professionals (ACR/ARHP) meeting being held Nov. 7-11, 2015 in San Francisco, Calif. Vectra DA is the first and only multi-biomarker blood test validated to measure disease activity in patients with RA and has been evaluated in multiple studies, resulting in 17 scientific publications.

“Much work has been done over the past decade to develop and validate Vectra DA, and establish the test as an objective measure for assessing disease activity in patients with rheumatoid arthritis,” said Elena Hitraya, M.D., Ph.D., chief medical officer, Crescendo Bioscience. “This year, our collaborators are presenting data on the role of Vectra DA in predicting response to second-line therapy. In addition, data will be presented examining Vectra DA’s ability to predict which patients may be able to successfully taper or withdraw from treatment.  These data are important and deserve further exploration because they have the potential to help physicians tailor treatment plans for their patients and improve the use of healthcare resources.”

A summary of the highlighted Crescendo Bioscience presentations at ACR (#ACR15) follows:


Title: The multi-biomarker disease activity score in methotrexate incomplete responders predicts clinical responses to non-biological vs. biological therapy in early RA​.
Authors: K. Hambardzumyan, R. Bolce, S. Saevarsdottir, K. Forslind, J.A. Karlsson and R.F. van Vollenhoven.
Date:  Sunday, Nov. 8, 2015: 9:00 – 11:00 a.m. PT.
Location: Poster, Abstract 618. 

The objective of this study was to evaluate whether the Vectra DA score could be used to predict the optimal choice of second-line treatment for 157 patients with RA who were MTX incomplete responders (MTX-IR). The findings demonstrated that, in patients with early RA and incomplete response to MTX, the Vectra DA test predicted the relative efficacy of second-line treatment with triple therapy versus anti-TNF.

“Predicting response to drug therapy is an important goal for personalizing treatment for individuals with RA,” said Ronald F. van Vollenhoven, M.D., Ph.D., Department of Medicine, Karolinska Institute in Stockholm, Sweden and the study’s lead investigator. ”In this study, patients with a low Vectra DA score were more likely to respond to conventional triple therapy than to anti-TNF therapy. These findings may help facilitate and improve the development of individualized and cost-effective treatment plans for patients with RA.”

Title: Prediction of disease relapses by multi-biomarker disease test activity in rheumatoid arthritis patients tapering DMARD treatment​.
Authors: J. Rech, A.J. Hueber, M. Englbrecht, S. Finzel, J. Haschka, B. Manger, A. Kleyer, M. Reiser, H-P Tony, S. Kleinert, M. Feuchtenberger, M. Fleck, K. Manger, W. Ochs, M. Schmitt-Haendle, J. Wendler, F. Schuch, M. Ronneberger, H-M Lorenz, H. Nüßlein, R. Alten, J. Fogagnolo Cobra, J.C. Henes, K. Krüger and G.A. Schett.
Date: Tuesday, Nov. 10, 2015: 9:00 – 11:00 a.m. PT.
Location: Poster, Abstract: 2584.                        

This study analyzed the role of Vectra DA in predicting disease relapse in patients with RA in sustained remission, following the tapering of treatment with disease modifying anti-rheumatic drugs (DMARDs).  Vectra DA improved the prediction of relapse in RA patients in stable remission undergoing DMARD tapering. Additionally, when combined with anti-citrullinated protein antibody (ACPA) status, Vectra DA resulted in a correct case classification of relapse in approximately 80 percent of patients.

Title: Multi-biomarker disease activity score as a predictor of flare in patients with rheumatoid arthritis who stop TNF-alpha-inhibitor therapy.
Authors: F. Lamers-Karnebeek, M. Ghiti Moghadam, H.E. Vonkeman, J. Tekstra, A. Schilder, H. Visser, P.M. ten Klooster, E.H. Sasso, D. Chernoff, W. Lems, D. van Schaardenburg, R. Landewé, L. Van Albada, T.R.D.J. Radstake, P. van Riel, M.A.F.J. van de Laar and T. Jansen.
Date: Tuesday, Nov. 10, 2015: 9:00 – 11:00 a.m. PT.
Location: Poster, Abstract: 2594.

This study evaluated the Vectra DA score as a predictor of flare after discontinuation of treatment with tumor necrosis factor inhibitor (TNFi).  Data were assessed from 439 RA patients who were randomized to stop TNFi treatment in the Dutch multi-center POET trial. The Vectra DA score was evaluated in all patients at baseline.  Flare was defined as: 1) re-initiating TNFi treatment, 2) escalation of any medication, and 3) physician-reported flare. This study found that a high Vectra DA score at baseline was an independent predictor of flare within 12 months of discontinuing TNFi therapy.

About Vectra® DA

Vectra DA is the only multi-biomarker blood test for rheumatoid arthritis (RA) disease activity that integrates the concentrations of 12 serum proteins associated with RA disease activity into a single objective score, on a scale of 1 to 100, to help physicians make more informed treatment decisions. Vectra DA testing is performed at the Crescendo Bioscience state-of-the-art CLIA (Clinical Laboratory Improvement Amendments) facility. Test results are reported to the physician 5 to 7 days from shipping of the specimen to Crescendo Bioscience. Physicians can receive test results via standard mail, by fax or via the private web portal, VectraView. For more information on Vectra DA, please visit:
