Descripción detallada
This is a Phase II open-label study to assess the safety, tolerability, Pharmacokinetics, and efficacy of surovatamig in adult participants with pMN, who are positive for anti-PLA2R antibodies and have heavy and persistent proteinuria with a high risk of progressing to end stage kidney disease.
The study will be conducted across approximately 30 to 40 study sites in approximately 10 countries. The study consists of 2 parts (Part A Multiple ascending with sentinel dosing and Part B Multiple ascending doses), with each consisting of 3 periods (ie, screening period, treatment period, and follow-up period; up to 26 months in total).
