A Multicenter, Randomized, Double-blind, Placebo-controlled Study of Enzastaurin for the Prevention of Arterial Events in Patients With Vascular Ehlers-Danlos Syndrome (vEDS) Confirmed With COL3A1 Mutations, Followed by an Open Label Extension (OLE)
The purpose of this study is to investigate the efficacy of enzastaurin compared to placebo in preventing arterial events (rupture, dissection, pseudoaneurysm, carotid-cavernous sinus fistula, or aneurysm, fatal or not) leading to intervention or mortality attributable to an arterial event in patients with vEDS confirmed with pathogenic heterozygous COL3A1 gene mutations predicted to derive a mutant protein.
• Subjects aged 18 - 60 years old at time of initial screening.
• Adolescent subjects aged 12 - 17 years old, may be considered to enroll later in the clinical trial pending interim analysis.
• Diagnosis for VEDS (vascular Ehlers Danlos Syndrome), with a confirmed and documented COL3A1 genetic variant.
• Subject should be stable, having no VEDS-related vascular events within the past 3 months prior to enrollment.
• Confirmed use of contraception for both male and female participants.
