Tests treatment safety and results for Primary IgA Nephropathy
Official title A Study to Evaluate the Efficacy and Safety of Sefaxersen (RO7434656) in Participants With Primary Immunoglobulin A (IgA) Nephropathy at High Risk of Progression
ClinicalTrials.gov ID: NCT05797610
What this study is testing
What is Sefaxersen (RO7434656)?
Sefaxersen (RO7434656) is an investigational medicine, given as an injection under the skin, being studied as a potential treatment for primary iga nephropathy.
Also referred to as Sefaxersen.
Plain-language explanation of the investigational treatment - it is being studied and is not an approved or proven therapy. The study team can confirm the details.
- What it's testing
- The purpose of this study is to evaluate the efficacy, safety, and pharmacokinetics of sefaxersen (RO7434656), a novel Antisense Oligonucleotide (ASO) therapy in participants with primary IgA nephropathy (IgAN) who are at high risk of progressive kidney disease despite optimized supportive care.
- Phase 3: a large, late-stage study
A plain-language read of the study's public ClinicalTrials.gov listing. The study team confirms the details.
