Other	Change From Baseline in Symptoms and Health-Related Quality of Life at Week 105 as Assessed Using the RAND Kidney Disease and Quality of Life 36-Item (KDQOL-36) Short Form	The RAND KDQOL-36 is an abbreviated questionnaire that combines the generic and disease-specific components to assess participant's health-related quality of life. This 36-item questionnaire includes the RAND 12, Version 1 (12 items) and 3 disease-related domains, symptoms/problems (12 items), burden of kidney disease (4 items), and effects of kidney disease (8 items). It uses a recall of 4 weeks, and items are assessed on 3- to 5-point Likert scales or with a dichotomous response option. Higher score indicates better health. The raw scores are transformed linearly to a range of 0 to 100, with higher scores indicating better health.	Baseline, Week 105
Primary	Change From Baseline in the Urine Protein-to-Creatinine Ratio (UPCR) at Week 37	UPCR will be assessed in urine sampled over 24 hours.	Baseline, Week 37
Secondary	Estimated Glomerular Filtration Rate (eGFR) Slope at Week 105 from Baseline	eGFR will be calculated using the 2021 Chronic Kidney Disease Epidemiology Collaboration (CKD-EPI) creatinine equation.	Baseline, Week 105
Secondary	Time to the Composite Kidney Failure Endpoint	Time to the composite kidney failure endpoint is defined as receipt of kidney transplantation, need for kidney replacement therapy, or a sustained decline in eGFR of = 30% or a sustained eGFR <15 mL/min/1.73m^ 2 over at least 4 weeks (both eGFR criteria requires two consecutive central laboratory eGFR values meeting criteria = 4 weeks apart), whichever occurs first, without the receipt of other immunosuppressive or background therapies for the treatment of IgAN.	Up to approximately 7 years
Secondary	Change From Baseline in Fatigue at Week 105	Fatigue will be assessed with the Functional Assessment of Chronic Illness Therapy-Fatigue subscale (FACIT-F). The FACIT-F Scale is a 13-item scale used to measure self-reported fatigue. Items are assessed on a 5-point Likert scale, with responses ranging from 0 for "not at all" to 4 for "very much". The total raw score is the sum of the values of each scored question and ranges from 0 to 52. A higher score indicates less fatigue.	Baseline, Week 105
Secondary	Percentage of Participants with Treatment-Emergent Adverse Events (TEAEs)		Up to approximately 7 years
Secondary	Plasma Concentration of RO7434656		Up to approximately 7 years
