Abstract

OBJECTIVES: ANCA-associated vasculitis (AAV) are chronic diseases with relapses that associate organic damage because of the disease and its treatment. Avacopan is a new treatment indicated for AAV. We present the first experiences with avacopan in Spain as part of an Early Access program.

METHODS: Patients with AAV who started avacopan between June 2022-September 2023 were included. For comparison, a historical cohort of patients diagnosed with AAV around the same time and treated without avacopan was also included.

RESULTS: 29 patients treated with avacopan were analyzed. Twelve patients (41.4%) were male, median age was 56 years. Most of patients were ANCA MPO positive (21/29, 72.4%). The most frequently affected organ was the kidney (23/29, 79.31%), with a mean eGFR of 23.2 ml/minMedian follow-up was 456.8 ± 181.7 days with a remission rate of 86.2%. eGFR increased from 23.2 ± 11.2-38.38 ± 18.55 ml/min after 12 months of diagnosis.2 patients had Adverse Events related to avacopan as severe neutropenia and a gastrointestinal affectation , 13 infections were reported and 1 death.Patients treated with avacopan received a significantly lower cumulative dose of prednisone at 6 and 12 months (p-values of 0.02 and <0.01, respectively) compared with historical controls. The evolution of GFR at 1 year of follow-up and the incidence of relapse were similar in both groups.

CONCLUSION: The combination of avacopan in clinical practice presents a good safety profile and provides added value by contributing to the control of AAV activity, increase GFR, and removal of steroids.
