Brief summary

A Phase 1, First-in-human, Randomized, Double-blind, Placebo-controlled, Single and Multiple Ascending Intravenous Dose Study to Assess the Safety, Tolerability and Pharmacokinetics. VGL101 or placebo will be administered to healthy volunteers to test if VGL101 is safe and can be explored as a treatment for Adult onset leukoencephalopathy with axonal spheroids and pigmented glia.

Interventions

VGL101 will be administered via intravenous infusion once in the single ascending dose (cohorts 1A-8A) part, and three times (every 28 days) in the multiple ascending dose (cohorts 1B-4B) part. The starting dose of VGL101 will be 1mg/kg and each cohort will increase by 2-3x. The doses selected for the multiple ascending dose cohorts will be selected after a review of the single ascending dose data by a safety review committee.
