Brief summary

Nine months multi-center prospective, randomized observational study, two arm trial to evaluate the effect of MBDA score-guided care on disease activity and medical costs.

Detailed description

Nine months multi-center prospective, randomized observational study, two arm trial to evaluate the effect of MBDA score-guided care on disease activity and medical costs. To investigate whether treatment decisions guided by MBDA scores result in reduced disease activity and overall medical cost among patients with RA relative to usual care (UC).

Inclusion criteria

* Willing and able to sign an informed consent form (ICF) * Age at least 18 years old at screening visit * Diagnosed with RA according to 1987 or 2010 criteria of the American College of Rheumatology * Actively managed by a CareFirst health care practitioner * Currently taking one or more biologic and/or non-biologic DMARDs listed in Appendix 2 * Currently has CareFirst medical coverage

Exclusion criteria

* Active infection * History of malignancy within the past 5 years or any evidence of persistent malignancy, except fully excised basal cell or squamous cell carcinomas of the skin, or cervical carcinoma in situ that has been treated or excised in a curative procedure * Current enrollment in another clinical trial * On non-biologic DMARD monotherapy or combination therapy with stable disease for ≥6 months * Any condition or circumstance that makes it likely the patient will not be able to complete the 9-month trial

Design outcomes

Primary

MeasureTime frameDescription
Mean MBDA ScoreBaseline to 9 monthsChange in disease activity from baseline to month 9 as measured by mean MBDA score. MBDA Score stands for the Vectra multi-biomarker disease activity (MBDA) blood test. Scale: Low (\>30); Moderate (30-44); High (\>44)

Secondary

MeasureTime frameDescription
Changes in Overall Medical CostsBaseline to 1 yearChanges in overall medical costs, RA-related medical costs, pharmacy costs, RA treatment medication costs, and biologic DMARD medication costs from baseline to one year, as defined in Appendix 2.
Medical UtilizationBaseline to 1 yearMedical utilization metrics (admissions, readmissions, emergency room visits, physician visits, etc.).
Proportion of Patients who Showed a Response to MedicationBaseline to month 9Proportion of patients who showed a response to medication, defined as a decrease in MBDA score of at least 8 from baseline to month 9.
Pharmacy UtilizationBaseline to 1 yearPharmacy utilization metrics (days' supply, prescriptions, etc.).
Treatment AdherenceBaseline to 1 yearTreatment adherence metrics measured according to medical possession ratio and time to discontinuation.

Other

MeasureTime frameDescription
Proportion of Patients with Non-High MBDA ScoresBaseline to month 9Proportion of patients with non-high (≤44) MBDA scores from baseline to month 9.
Overall Medical CostsBaseline to 1 yearOverall medical costs, pharmacy costs, RA treatment medication costs, and biologic DMARD medication costs (Appendix 2) from baseline to one year according to: 1. Baseline MBDA score category (low \<30, moderate 30-44, high \>44). 2. Whether treatment decisions were consistent with the MBDA score-based treatment guidance in Appendix 1 (guided treatment arm only). 3. Whether MBDA score category changed from baseline to month 9. 4. Whether biologic DMARD use was tapered.
