Study Overview

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.

Arms & Interventions

Group B (JAK inhibitor)

Experimental

Rheumatoid arthritis patients that have failed DMARD therapy will undergo a synovial biopsy under ultrasound guidance and sterile technique. Upon analysis of the sample, patients that are falling into the lymphoid- myeloid phenotype will be assigned to receive JAK inhibitor medication at the discretion of the treating physician.

Intervention: JAK inhibitor (Drug)

Group C (Anti-TNF or JAK inhibitor)

Experimental

Rheumatoid arthritis patients that have failed DMARD therapy will undergo a synovial biopsy under ultrasound guidance and sterile technique. Upon analysis of the sample, patients that are falling into the pauci-cellular phenotype will be randomized to either anti-TNF or JAK inhibitor medication 1:1.

Intervention: Anti-TNF (Drug)

Group A (Anti-TNF)

Experimental

Rheumatoid arthritis patients that have failed DMARD therapy will undergo a synovial biopsy under ultrasound guidance and sterile technique. Upon analysis of the sample, patients that are falling into the diffuse myeloid phenotype will be assigned to receive anti-TNF medication at the discretion of the treating physician.

Intervention: Anti-TNF (Drug)

Group C (Anti-TNF or JAK inhibitor)

Experimental

Rheumatoid arthritis patients that have failed DMARD therapy will undergo a synovial biopsy under ultrasound guidance and sterile technique. Upon analysis of the sample, patients that are falling into the pauci-cellular phenotype will be randomized to either anti-TNF or JAK inhibitor medication 1:1.

Intervention: JAK inhibitor (Drug)

Outcomes

Primary Outcomes

Change in DAS28 score

Time Frame: Baseline, 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 Outcomes

  • Change in cellular phenotype(Baseline, Visit 3 (12 weeks))
  • Change in power Doppler activity(Baseline, Visit 3 (12 weeks))
  • Change in HAQ score(Baseline, Visit 3 (12 weeks))
