A Study to Evaluate the Safety and Pharmacokinetics of Single and Multiple Doses of Prosetin in Healthy Volunteers and Participants With ALS

PRO-101 is a four-part study. Parts A and B, which respectively evaluated the safety, tolerability, and PK of single and multiple ascending doses of prosetin in 48 healthy volunteers, have been completed. Parts C and D, which are ongoing, will evaluate the effects of prosetin on safety, tolerability, PK, and biomarkers in 24 participants with ALS. Part C is a double-blind, placebo-controlled, multiple ascending dose component of the study, and Part D is an optional 52-week open-label extension available to ALS participants who complete 14 days of dosing in Part C.
