Brief summary

SYBRA is an open-label, phase 3, randomized controlled clinical trial that aims to assess the use of synovial biopsies in predicting response to biologic therapy in patients with rheumatoid arthritis that have failed disease-modifying drugs. The project has the potential to help change the current practice by offering the best treatment option. The decision to choose the best treatment for a particular patient is especially important in the context of the growing number of therapies available as a first-line option and the lack of specific biomarkers to predict response to treatment.

Interventions

Upon analysis of the sample, patients that are falling into specific phenotypes (diffuse myeloid or pauci-cellular phenotypes) will be assigned to receive anti-TNF as biologic DMARD medications.

Upon analysis of the sample, patients that are falling into specific phenotypes (lymphoid- myeloid or pauci-cellular phenotypes) will be assigned to receive JAK inhibitors as biologic DMARD medications.

Inclusion criteria

* Subject should be capable of consent * Age 18 and older * Classified as rheumatoid arthritis as per EULAR/ACR criteria 2010 * Failed one DMARD (Methotrexate, leflunomide, Sulfalsalazine, hydroxychloroquine) * Can be on steroid dose \<7.5mg * Quantiferon negative * Hepatitis B, C negative * No recent history (\<5y) of malignancy

Design outcomes

Primary

MeasureTime frameDescription
Change in DAS28 scoreBaseline, Visit 3 (12 weeks)Change in DAS28 score indicating remission compared to baseline in at least 50% of patients, where DS28\<2.6 indicated remission. \* DAS score: disease activity score, where \<2.6 indicates remission, 2.6-3.2 low disease activity. 3.2-5.1 moderate disease activity; \>5.1 high disease activity; higher values suggest worse outcomes.

Secondary

MeasureTime frameDescription
Change in HAQ scoreBaseline, Visit 3 (12 weeks)Significant decrease in HAQ score compared to baseline. \* HAQ (Health assessment questionnaire). Scores vary from 0-to 3. Higher scores are associated with worse outcomes.
Change in power Doppler activityBaseline, Visit 3 (12 weeks)Change in power Doppler activity compared to a baseline where no power Doppler activity indicates remission. Measurement in Doppler activity on ultrasound using a grading system developed by EULAR. \* Global EULAR-OMERACT Synovitis Score: scores range from 0-3 for each scanned joint. Higher scores correlate with worse outcomes.
Change in cellular phenotypeBaseline, Visit 3 (12 weeks)Change in cellular phenotype compared to baseline. Estimation of change in the number of inflammatory cells as per the grading criteria.
