  Purpose

The goal of this study is to enable the study sponsor to assess the impact of a marketed or validated blood test has on physicians' clinical treatment decision making when treating RA patients who have been taking methotrexate.

Ultimately, the blood test will allow treating physicians to modify current methotrexate therapy in partially responding Rheumatoid Arthritis (RA) patients' therapy, on an individualized basis, as a means of improving clinical outcomes.

The study requires a blood sample from RA patients who have been on methotrexate therapy for a minimum of 3 months and are having an inadequate response to therapy. Physicians will then be provided with the results of the test indicating the methotrexate polyglutamate (active metabolites of methotrexate) levels in the patient's red blood cells as a means to help determine whether a patient's exposure to methotrexate has been optimized.

Detailed Description:

This study is currently enrolling individuals who have an established diagnosis of RA and are receiving methotrexate as part of their therapy. Patients are required to submit a blood sample. There is no cost to volunteers who participate.

Criteria

Inclusion Criteria:

  • Able to read, understand, and sign the informed consent form
  • Able to read, write, and speak English
  • ≥18 years of age
  • Diagnosed with RA within past 24 months (waiver)
  • Taking oral methotrexate therapy for a minimum of 3 months
  • Considered to have an insufficient response to methotrexate and therefore a candidate for change to therapy, including changing MTX dose or changing route of delivery, or adding or switching DMARDs (including but not limited to biologic DMARDs)

Exclusion Criteria:

  • Prior exposure of the study center, study physician or study patient to the Avise PG laboratory test
  • Patients with known abnormal hepatic and or hematological parameters
  • Use of prednisone >10mg/day (or its equivalent)
