Phase 1
Recruiting
Conditions
Primary Membranous Nephropathy
Interventions
Registration Number
NCT05800873
Lead Sponsor
Everest Medicines (China) Co.,Ltd.
Brief Summary

EVER001 is a highly selective, oral, reversable, covalent Bruton tyrosine kinase (BTK) inhibitor with high selectivity over other kinases, which is being developed to treat proteinuric glomerular diseases.

The overall aim of the study is to evaluate the efficacy, safety, pharmacokinetics and pharmacodynamics of EVER001 in subjects with selected proteinuric glomerular diseases. The first targeted is primary membranous nephropathy.
