Poster Presentations

  • Title: Examination of Diurnal and Daily Variation of the Multi-Biomarker Disease Activity (MBDA) Score in RA to Establish a Minimally Important Difference.
    Presenter: David Chernoff
    Date: Poster Session A, Sunday, Nov. 13, 2016: 9:00-11:00 a.m. ET.
    Abstract: 535.

This study evaluated the biological variability in Vectra DA scores over a 24-hour period and day-to-day in 28 patients with rheumatoid arthritis (RA) with the goals of determining a minimally important difference (MID) and establishing a cut point for a meaningful change in Vectra DA scores over time.  The results showed that, based on the short-term variability in the Vectra DA score among stable RA patients tested serially over time, the MID in the score was 9 units.  Changes exceeding this threshold are unlikely due to diurnal and daily biological variations alone. Based on these data, blood samples for Vectra DA testing taken during normal office hours (8:00 a.m. to 5:00 p.m.) would not be expected to be impacted by a diurnal variation in the Vectra DA score in clinically stable patients.

  • Title: Biomarker-Related Risk for Myocardial Infarction and Serious Infections in Patients with Rheumatoid Arthritis: A Population-Based Study.
    Presenter: Jeff Curtis
    Date: Poster Session B, Monday, Nov. 14, 2016: 9:00-11:00 a.m. ET.
    Abstract: 1492.

This study evaluated the utility of Vectra DA in assessing the risk of cardiovascular outcomes and serious infections in a large U.S. Medicare claims database of patients with RA (approximately 17,000 patients with linkable Vectra DA scores).  Researchers examined the relationship between the Vectra DA score and the risk of developing infections requiring hospitalization, myocardial infarction (MI) and a composite coronary heart disease (CHD) outcome, including percutaneous coronary intervention and coronary artery bypass graft. The results showed that high Vectra DA scores were associated with an increased risk for all of these outcomes.  These findings indicate that the use of the Vectra DA score to risk-stratify patients for these serious adverse events may help clinicians identify those at highest risk.

  • Title: Predicting Flare and Sustained Clinical Remission After Adalimumab Withdrawal Using the Multi-Biomarker Disease Activity (MBDA) Score. ​
    Presenters: Shintaro Hirata, Yoshiya Tanaka
    Date: Poster Session C, Tuesday, Nov. 15, 2016: 9:00-11:00 a.m. ET.
    Abstract: 2639.

This study evaluated the Vectra DA (MBDA) score as a predictor of flare or sustained clinical remission after discontinuation of adalimumab (ADA) in patients with established RA from the HONOR study.  The analysis included 42 patients receiving ADA and methotrexate (MTX) who maintained DAS28-ESR remission (<2.6) for ≥24 weeks and agreed to discontinue their ADA.  Clinical disease activity, functional status and joint damage were recorded at ADA discontinuation (baseline) and after 24 and 52 weeks.  Vectra DA scores were measured at ADA discontinuation, and the ability of Vectra DA to predict flare or remission was assessed at six months and one year. All patients had DAS28-ESR <2.6 at baseline and the median Vectra DA score at baseline was 24.5 with 22 patients in remission, six with low, nine with moderate and five with high Vectra DA scores.  At 52 weeks, the rate of flare and sustained remission by Vectra DA category (remission/low/moderate/high) was 13.6, 50.0, 33.3 and 60.0 percent (p=0.033) and 63.6, 33.3, 33.3, and 0 percent (p=0.0066), respectively.  These findings suggest that the Vectra DA score could predict flare and biologic-free remission in patients in stable remission undergoing ADA withdrawal while maintaining MTX treatment.  The results point to the potential clinical utility of Vectra DA for guiding treatment decisions in patients with RA.

  • Title: Multi-Biomarker Disease Activity (MBDA) Score and Prediction of Radiographic Progression in a Randomized Study of Patients with Early RA Treated with Methotrexate Alone or with Adalimumab.
    Presenter: Cecilie H. Brahe
    Date: Poster Session C, Tuesday, Nov. 15, 2016: 9:00-11:00 a.m. ET.
    Abstract: 2520.

The objectives of this study were to evaluate 180 early RA patients from the OPERA trial for associations between the baseline Vectra DA score and 12-month radiographic outcomes, and to assess the value of adding the Vectra DA score to the anti-cyclic citrullinated peptide (anti-CCP) status for predicting radiographic progression (RP).  The results showed that a high baseline Vectra DA score was a strong, independent predictor of RP and it added value to anti-CCP status.  Patients with a high baseline Vectra DA score (>44) were more likely to progress radiographically (31 percent), while only three percent of patients with a score (≤44) progressed (p<0.01).  High versus moderate baseline DAS-CRP was not associated with RP (p=1.0). 34 percent of anti-CCP positive and 12 percent of anti-CCP negative patients had RP (p<0.002); however, none of the anti-CCP positive patients with a Vectra DA score ≤44 progressed radiographically, whereas stratifying by DAS-CRP had no added value to the anti-CCP alone.  These data further support the ability of Vectra DA to predict radiographic progression.

About Rheumatoid Arthritis
Rheumatoid arthritis is a chronic, systemic inflammatory condition that is often characterized by symptoms that include pain, stiffness and inflammation of the joints, and in some cases, joint destruction and disability.  An estimated 1.5 million Americans have the condition, which affects nearly three times as many women as men. While the cause of RA is unknown, many cases are believed to result from genetic and environmental factors.

About Vectra® DA
Vectra DA is the only multi-biomarker blood test for rheumatoid arthritis 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:
