To date, there is no published overview of the drug pipeline in granulomatosis with polyangiitis (GPA), a rare disease. The aim of this study was to identify clinical trials from two study repositories. A review of clinical trials was conducted using publicly available data. Clinicaltrials.gov and International Clinical Trials Registry Platform were searched from inception until 25 September 2022. Only GPA-specific studies were included; these were described in detail. A total of 137 studies were identified in the trial repositories, of which 108 (79%) studies were found to concern GPA. Of these 108 studies, 67 enrolled GPA patients to investigate pharmacotherapy in this disease (62%). Most studies included all severity types (n = 51; 76%); the scope of almost half of the studies was remission induction (n = 33; 49%). The drug class which was by the most widely investigated in trials was the noncorticosteroid immunosuppressant drug class (46; 68.7%), monoclonal antibodies (32; 47.8%), and corticosteroids (31; 46.3%). There is a need for more GPA trials to generate evidence on effectiveness in terms of severity-specificity and maintenance of remission.

Abstract
To date, there is no published overview of the drug pipeline in granulomatosis with polyangiitis (GPA), a rare disease. The aim of this study was to identify clinical trials from two study repositories. A review of clinical trials was conducted using publicly available data. Clinicaltrials.gov and International Clinical Trials Registry Platform were searched from inception until 25 September 2022. Only GPA-specific studies were included; these were described in detail. A total of 137 studies were identified in the trial repositories, of which 108 (79%) studies were found to concern GPA. Of these 108 studies, 67 enrolled GPA patients to investigate pharmacotherapy in this disease (62%). Most studies included all severity types (n = 51; 76%); the scope of almost half of the studies was remission induction (n = 33; 49%). The drug class which was by the most widely investigated in trials was the noncorticosteroid immunosuppressant drug class (46; 68.7%), monoclonal antibodies (32; 47.8%), and corticosteroids (31; 46.3%). There is a need for more GPA trials to generate evidence on effectiveness in terms of severity-specificity and maintenance of remission.
