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

Phase 1
Recruiting
Conditions
Amyotrophic Lateral Sclerosis
Interventions
Drug: placebo
Registration Number
NCT05279755
Lead Sponsor
ProJenX
Brief Summary

The primary purpose of this study is to evaluate the safety and tolerability of prosetin in healthy volunteers and participants with ALS.

Detailed Description

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.

GroupInterventionDescription
Part A - single dose of placeboplaceboHealthy volunteers were administered a single dose of prosetin-matched placebo oral solution.
Part A - single ascending doses of prosetinprosetinHealthy volunteers were administered a single dose of prosetin oral solution at 0.03, 0.06, 0.12, or 0.24 mg/kg.
Part B - multiple doses of placeboplaceboHealthy volunteers were administered a once-daily dose of prosetin-matched placebo for 14 days.
Part B - multiple ascending doses of prosetinprosetinHealthy volunteers were administered a once-daily dose of prosetin at 0.06 or 0.10 mg/kg for 14 days.
Part C - multiple doses of placebo in participants with ALSplaceboParticipants are administered a once-daily dose of prosetin-matched placebo for 14 days.
Part C - multiple ascending doses of prosetin in participants with ALSprosetinParticipants will be administered a once-daily dose of prosetin at multiple ascending dose levels for 14 days.
Part D - open-label administration of prosetin in participants with ALSprosetinParticipants will be administered a once-daily dose of prosetin for up to 52 weeks.
