Outcomes
Primary Outcome Measures
Change in Slope of First Morning Urinary PCR From the 8-week RAAS Blocker run-in Period to the 12-week CCX168 Treatment Period
The mean change in the slope of the urinary protein:creatinine ratio (UPCR, in mg/g/week) between the 8-week run-in period and the 12-week treatment period

Secondary Outcome Measures
Proportion of Subjects Achieving Renal Response From Baseline to Day 85
Renal Response defined as an improvement in proteinuria based on a decrease from baseline to Day 85 in proteinuria to a level <300 mg/g creatinine and maintaining eGFR within 15% of baseline.
Proportion of Subjects Achieving a Partial Renal Response From Baseline to Day 85
A partial renal response, defined as an improvement in proteinuria based on a decrease from baseline to Day 85 in proteinuria to a level <1 g/g creatinine and maintaining eGFR within 15% of baseline.
Change From Baseline to Day 85 in Vital Signs
Change in Systolic Blood Pressure From Baseline to Day 85
Change in Diastolic Blood Pressure From Baseline to Day 85

5. Study Description
Brief Summary
The primary safety objective of this study is to evaluate the safety and tolerability of CCX168 in subjects with IgAN on background supportive therapy with a maximally tolerated dose of RAAS blockade. The primary efficacy objective is to evaluate the efficacy of CCX168 based on an improvement in proteinuria.
