Clinical Trial Summary

The purpose of this study is to identify the most promising therapeutic strategy for patients with granulomatosis with polyangiitis and inadequate response to standard of care therapy. It will evaluate the efficacy to induce remission of three different salvage strategies including: a combination of rituximab with addition of a conventional disease-modifying antirheumatic drugs (either methotrexate, azathioprine or mycophenolate mofetil, but preferentially methotrexate); tocilizumab; or abatacept.


Description:

Granulomatosis with polyangiitis (GPA) is an anti-neutrophil cytoplasmic antibody (ANCA)-associated vasculitides (AAV). Combination of glucocorticoids and either cyclophosphamide or rituximab is the standard of care for remission-induction of new-onset organ-threatening or life-threatening GPA. Few patients fail to respond to both cyclophosphamide and rituximab, but it is not uncommon for patients to have persistent disease activity resulting in inability to taper glucocorticoids, which is also considered refractory disease. The current recommendations for patients with GPA refractory to remission-induction therapy are to switch from cyclophosphamide to rituximab or from rituximab to cyclophosphamide. However, there are no recommendations for the management of patients with inadequate response after both treatments. Treatment with a biologic disease-modifying antirheumatic drugs (DMARD) or a combination of rituximab and a cDMARD are potential treatments options but have not been properly evaluated in such cases. Among biologic DMARD that have been evaluated in AAV, some have shown promising results, including tocilizumab and abatacept. Identifying the most promising therapeutic strategy for patients with GPA and inadequate response to standard of care therapy may improve management of GPA.

Secondary Corticosteroids use The area under the curve for corticosteroids at week 26 and 52 week 26 and 52
Secondary Vasculitis Damage Index The Vasculitis Damage Index (VDI, scoring from 0 to 58, higher scores indicating more damage) at week 26 and 52 week 26 and 52
Secondary Health Assessment Questionnaire (HAQ) ranging from 0 to 3, with higher scores indicating worse functional impairment week 26 and 52
Secondary Short Form 36 (SF-36) Health questionnaire scores range from 0 to 100 for each component, with lower scores indicating greater impairment of quality of life week 26 and 52
