Arrowhead Pharmaceuticals Initiates Phase 1/2 Study of ARO-C3 for Treatment of Complement Mediated Diseases
AROC3-1001 (NCT05083364) is a Phase 1/2, placebo controlled, dose-escalating study to evaluate the safety, tolerability, pharmacokinetics, and pharmacodynamics of ARO-C3 in up to 24 adult healthy volunteers, up to 24 adult patients with paroxysmal nocturnal hemoglobinuria (PNH), and up to 14 adult patients with complement-mediated renal disease. In Part 1 in healthy volunteers, four cohorts with four escalating dose levels of ARO-C3 will be evaluated. Each cohort will enroll 6 eligible subjects who will be randomized to receive a single subcutaneous injection of ARO-C3 (n=4) or placebo (n=2). In Part 2, eligible subjects with PNH or complement-mediated renal disease will be enrolled to receive open-label ARO-C3 on day 1 and day 85 at one of two dose levels to be determined in Part 1. The primary objective of the study is to evaluate the safety, tolerability, pharmacokinetics, and pharmacodynamics of single doses of ARO-C3 in normal healthy volunteers and to evaluate the safety, tolerability, pharmacokinetics, and pharmacodynamics of multiple doses of ARO-C3 in subjects with PNH and in subjects with complement-mediated renal disease.
