Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

This is a phase 2a, multicenter, open-label study designed to evaluate the safety and efficacy of AT-1501 in patients with biopsy proven IgAN and at least 0.75 g/24 hours of protein in their urine at the time of screening.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

Phase 2a, multicenter, open-label study designed to evaluate the safety and efficacy of AT-1501 in patients with biopsy proven IgAN and at least 0.75 g/24 hours of protein in their urine at the time of Screening. Up to 42 eligible patients will receive one of 2 doses of AT-1501. All patients are scheduled to receive AT-1501 by intravenous infusion every 3 weeks for approximately 2 years.
