Treatment With Avacopan in Patients With Respiratory Tract Manifestations of Antineutrophil Cytoplasmic Antibody–Associated Vasculitis
Objective The ADVOCATE trial demonstrated that treatment of active granulomatosis with polyangiitis (GPA) and microscopic polyangiitis (MPA) with avacopan was noninferior in achieving remission at week 26 and superior for sustained remission at week 52 compared with a prednisone taper.

| description | Objective The ADVOCATE trial demonstrated that treatment of active granulomatosis with polyangiitis (GPA) and microscopic polyangiitis (MPA) with avacopan was noninferior in achieving remission at week 26 and superior for sustained remission at week 52 compared with a prednisone taper. This analysis of ADVOCATE evaluated the efficacy and safety of avacopan in patients with ear, nose, throat (ENT), or lung manifestations. Methods This post hoc analysis included patients enrolled in ADVOCATE with ENT or lung manifestations at baseline. Outcomes included remission at weeks 26 and 52, respiratory tract manifestations over time, relapse rate, glucocorticoid‐related toxicity, health‐related quality of life (HRQoL), and safety. Results ADVOCATE included 144 patients with ENT manifestations (avacopan: n = 75, prednisone taper: n = 69) and 142 with lung manifestations (avacopan: n = 71, prednisone taper: n = 71). Among patients with ENT manifestations, remission was achieved at week 26 by 72.0% (avacopan group) and 71.0% (prednisone taper group) and was sustained at week 52 by 62.7% (avacopan) and 53.6% (prednisone taper). Among patients with lung manifestations, remission was achieved at week 26 by 73.2% (avacopan) and 66.2% (prednisone taper) and sustained at week 52 by 67.6% (avacopan) and 53.5% (prednisone taper). The relapse rate, glucocorticoid toxicity, and measures of HRQoL favored avacopan for both respiratory tract manifestation groups. Safety was comparable across treatment groups. Conclusion Patients with GPA or MPA with ENT or lung manifestations demonstrated similar responses to avacopan, reflecting results reported in the overall ADVOCATE trial population and supporting the administration of avacopan in these subgroups. |
