Summary
Brief summary
The purpose of AROC3-1001 is to evaluate the safety, tolerability, pharmacokinetics and/or
pharmacodynamics in adult healthy volunteers (HVs) and in adult patients with
complement-mediated renal disease (C3 Glomerulopathy [C3G] and IgA Nephropathy [IgAN]). In
Part 1 of the study, HVs will receive either one or two doses of ARO-C3 or placebo. In Part 2
of the study, adult patients with C3G/IgAN will receive 3 open-label doses of ARO-C3. Dose
levels in Part 2 will be determined based on cumulative safety and pharmacodynamic data from
Part 1.
