简要总结

The purpose of the study is to assess the effect of zigakibart on IgA nephropathy (IgAN) disease progression.

详细描述

This is an open-label multicenter study where participants are randomized into one of two groups, where the only difference between the groups is the on-treatment biopsy time point, end of the first year of treatment (Group A) or at the end of the second year of treatment (Group B).

The total study duration for each participant may be up to 125 weeks, including the maximum screening period (8 weeks), the treatment period (104 weeks), and the safety follow up period (13 weeks).

入选标准

  • •Primary IgAN, confirmed by kidney biopsy, within 5 years prior to Screening
  • •eGFR ≥45 mL/min/1.73 m2, based on the 2021 CKD-EPI equation, at Screening
  • •Persistent proteinuria, defined as either
  • •Total Urine Protein ≥0.5 g/day or UPCR ≥0.5 g/g in a 24-hour urine collection, at Screening, despite maximally tolerated dose or poorly tolerated supportive therapy or

  • •Planned initiation of, or recently (within 24 weeks) initiated, treatment with glucagon-like peptide-1 agonists at screening
  • •Other protocol-defined inclusion/exclusion criteria may apply.
