Assess Response to Therapy

Changes in Vectra scores provide quantitative insight to help assess your patients’ responses to therapy.

Vectra has assessed rheumatoid arthritis disease activity in response to many currently available therapeutic options, including:

  • Methotrexate ± corticosteroids1,2,3
  • Biologic therapy (abatacept, adalimumab, etanercept, golimumab, infliximab and tocilizumab*4-8)
  • Tofacitinib9
* Change in Vectra score during tocilizumab treatment may underestimate the change in clinical response.7,8 For more information on this topic please visit Frequently Asked Questions. 


Vectra algorithm scores differed significantly between EULAR response categories in anti-TNF-treated patients.5
