Vical Incorporated and Astellas Pharma Inc. announced topline results from a randomized, double-blind, placebo-controlled phase 2 study evaluating the safety and efficacy of cytomegalovirus (CMV) vaccine, ASP0113, versus placebo in kidney transplant patients receiving an organ from a CMV-seropositive donor. Results from the study demonstrated that the trial did not meet its primary endpoint, which was the proportion of patients having CMV viremia defined as a plasma viral load of = 1000 IU/ml by central laboratory assay through one year after first injection of study drug. Additionally, the secondary endpoints of CMV-associated disease and CMV-specific antiviral therapy, which were evaluated by an independent, blinded Adjudication Committee, were similar in both treatment groups.
