Detailed Description

This first-in-human study consists of 5 parts based on the subject population. Part 1 is a randomized, double-blind, placebo-controlled, single-ascending dose (SAD) evaluation of IV or SC VGA039 or placebo in up to 8 cohorts in healthy volunteers. Part 2 is an open-label, SAD of SC or IV VGA039 in up to 8 cohorts in subjects diagnosed with VWD. All participants will be enrolled, treated, and followed up for 15 weeks (IV SAD) or 8 weeks(SC SAD). Part 3 is an open-label, Phase 1b study of SC multiple doses (MD) of VGA039 in up to 4 cohorts. Part 4 is an open-label, Phase 2 study of SC single, surgical prophylaxis (SP) doses of VGA039 administered prior to a minor surgical procedure in subjects diagnosed with VWD in up to 2 cohorts. Part 5 is an open-label extension (OLE) study of SC MD of VGA039 in eligible subjects diagnosed with VWD who have previously participated in a VGA039 interventional trial.
