About VTL-308

VTL-308 is the Company's phase 3 randomized, controlled, open-label trial, designed to evaluate the ELAD System in subjects with severe acute alcoholic hepatitis (sAAH) who meet criteria based on learnings from pre-specified and post-hoc analyses of the Company's VTI-208 clinical trial. Subjects must be under the age of 50, have a MELD score under 30, an INR of 2.5 or below, a creatinine level below 1.3 mg/dL, and a bilirubin level of at least 16 mg/dL. The primary endpoint is overall survival through at least 91 days assessed using the Kaplan Meier statistical method.  The trial is intended to enroll a minimum of 150 subjects, who will be randomized 1:1 to either ELAD therapy plus standard-of-care, or standard-of-care alone.  The Company expects to enroll subjects among roughly 40 sites in the US and EU.  Topline results from VTL-308 are anticipated in mid-2018.
