Vital Therapies Announces Characteristics of Early Subjects in VTL-308 Pivotal Study of ELAD System in Severe Alcoholic Hepatitis
SAN DIEGO, June 05, 2017 (GLOBE NEWSWIRE) -- Vital Therapies, Inc. (Nasdaq:VTL), a biotherapeutic company developing ELAD®, a cell-based therapy targeting the treatment of acute forms of liver failure, today released data describing the baseline characteristics of the 67 subjects enrolled as of the Company's last quarterly report on May 9, 2017 in study VTL-308, the Company's ongoing pivotal phase 3 study in subjects with severe alcoholic hepatitis.
The enrollment criteria for VTL-308 were devised based on extensive analysis of prior clinical data for the ELAD System, including the 203 subject randomized dataset from VTI-208, a prior Phase 3 trial. Based on pre-specified exploratory analyses, it was determined from VTI-208 that younger subjects, as well as those with severe liver disease but without evidence of other organ dysfunction at baseline, would comprise the population most likely to exhibit improved survival in the prospectively designed VTL-308 clinical trial. In particular, an optimized post-hoc subgroup (N=60) of the VTI-208 population provided guidance on the specific inclusion and exclusion criteria that should be applied.
As part of routine quality control of study conduct, the critical baseline characteristics of subjects enrolled in the VTL-308 study are monitored. As previously reported, 67 subjects were enrolled as of May 9, 2017, of a total anticipated cohort of at least 150 subjects. The characteristics of the first 67 subjects are shown below, in comparison to the characteristics of the subgroup population from VTI-208 on which the inclusion criteria were based:
|Data||Age (years)||MELD||Bilirubin (mg/dL)||INR||Creatinine|
|VTL-308 enrollment limits||<50 yrs||≤30||≥16 mg/dL||≤2.5||<1.3mg/dL|
|VTI-208 reference population|
(16.6 - 52.6)
(1.0 - 2.5)
(16.0 - 42.8)
(0.95 - 2.50)
No subjects outside the enrollment criteria have been enrolled in VTL-308 to date and, as can be seen from these data, the subject characteristics are closely tracking the reference VTI-208 subset.
Jan Stange, M.D., Ph.D., VTL's Chief Medical Officer noted, "In order for clinical trials to be successful it is essential that subjects enrolled are carefully monitored to ensure compliance with all inclusion and exclusion criteria. It is remarkable how closely the baseline characteristics of the first 67 subjects enrolled in VTL-308 compare with the population from VTI-208 on which the study design is based. We look forward to obtaining data from this prospective trial in this poorly-served, high-mortality population."
