This is a Phase 1, randomized, placebo-controlled, double-blind study to evaluate the safety, tolerability, pharmacokinetics (PK), and pharmacodynamics (PD) of single and multiple doses of VES001 in a two part followed by a multicenter, open-label Phase 1b study in asymptomatic GRN mutation carriers. Part A will evaluate the safety, tolerability, PK, and PD of single doses of VES001 in healthy volunteers. Part B will evaluate the safety, tolerability, PK, and PD of multiple doses of VES001 in healthy volunteers.
Part A will include six cohorts, with eight participants per cohort. Participants in each cohort will be randomised in a 6:2 ratio (VES001 vs. placebo). Part B will include three cohorts, with ten participants per cohort. Participants in each cohort will be randomised in a 8:2 ratio (VES001 vs. placebo).

VES001 is an oral, blood brain barrier penetrating ligand of sortilin.
A matching dosage form, indistinguishable from the active treatment will be used as the placebo treatment.
