The AFFINITY Study is a phase 2, open-label, basket study to evaluate the efficacy and safety of atrasentan in patients with proteinuric glomerular disease who are at risk of progressive loss of renal function. Four initial cohorts will consist of patients with:
- IgA nephropathy (IgAN) with urine protein:creatinine ratio (UPCR) of 0.5 to less than 1.0 g/g
- Focal segmental glomerulosclerosis (FSGS)
- Alport syndrome
- Diabetic kidney disease (DKD) on top of background care of a RAS inhibitor and SGLT2 inhibitor
Additional cohorts may be added as data is available.
Approximately 20 patients will be enrolled in each cohort (approximately 80 patients total) to receive 0.75 mg atrasentan for 52 weeks.
The primary objective of the study is to evaluate the effect of atrasentan on proteinuria (for IgAN, FSGS, and Alport syndrome patients) or albuminuria (for DKD patients) levels. Exploratory objectives include evaluating the change in kidney function over time as measured by eGFR, safety and tolerability.
To facilitate study participation over this time period, where allowed by local regulations, options for remote study visits using telemedicine and home health may be offered.
