R3R01 is investigational small molecule designed to decrease fat levels in certain cells in the kidney and therefore may improve kidney function and reduce damage in the kidney. This is a single arm open-label study enrolling patients in three cohorts. Cohort 1 will include 5 adult (≥18 y/o) patients from Cohorts 2 and 3 (including at least one patient from Cohort 2 and at least one patient from Cohort 3). Cohort 2 will include approximately 20 male and female patients from 12 years and older with X-linked Alport Syndrome (AS), and male and female patients with autosomal inherited AS. Cohort 3 will include approximately 30 male and female patients from age 12 to 75 years with a biopsy proven diagnosis who present with primary steroid-resistant focal segmental glomerulosclerosis (FSGS) with proteinuria.~All eligible patients will be enrolled to receive R3R01 over a treatment period of 12 weeks with a primary efficacy outcome as the percentage change in proteinuria from baseline to the end of treatment (Day 84) in each cohort as a whole
This is a Phase 2, Multi-center, Open-Label Study to Assess Safety, Tolerability, Efficacy and Pharmacokinetics of R3R01 in Alport Syndrome Patients with Uncontrolled Proteinuria on ACE/ARB Inhibition and in Patients with Primary Steroid-Resistant Focal Segmental Glomerulosclerosis
