Brief Summary

Open label pragmatic two-stage non-randomized trial comparing the effectiveness of five different standard of care treatment options for patients with relapsing polychondritis (RP).

Detailed Description

Twenty eligible patients with mild to moderately active RP within 60 days prior to screening will be enrolled to the study.

Subjects will be eligible to enroll into stage 1 if they are naïve to methotrexate (MTX) or azathioprine (AZA), or having active disease on MTX or AZA for 8 weeks or less. Patients naïve to MTX and AZA will be started on MTX. AZA will be started if there is a contraindication to MTX. Patients on MTX/AZA for 8 weeks or less with active disease will be continued with the respective medication.

Patients who do not meet primary effectiveness end point in Stage 1 or develop relapse of RP or intolerance to MTX/AZA will move to Stage 2.

Patients eligible to be enrolled to Stage 2 directly

1. History of intolerance or side effects to MTX or AZA with active disease

2. Currently on MTX or AZA for at least 8 weeks or has received it within the past 60 days for at least 8 weeks and still has mild/ moderate active disease

All patients in Stage 2 will be started on Tumor necrosis factor inhibitor (TNFi) or Interleukin 6 inhibitor (IL6i). The two TNFis that will be used in the trial are adalimumab or infliximab. The choice between the 2 TNFis will be based on patients' preference/ feasibility. The IL6i in the study will be tocilizumab.

All patients will receive glucocorticoids (GC) which will be tapered to 5 mg daily by week 21 according to a standardized schedule in both stages of the trial.

C. Mild to moderately active disease within 60 days prior to screening where the symptoms cannot be attributed to any cause other than RP and which, in the investigator's opinion, requires addition/ increase in prednisone dose between 20-60 mg/ day.

At the time of enrollment and during the trial, the following symptoms of active disease which will be evaluated:

1. Auricular inflammation: defined as increase/ new onset pain/ swelling/redness of external ear(s), ear canal
