Therefore HGF is a potential therapeutic agent for treatment of fatal liver diseases. We performed a translational medicine protocol with recombinant human HGF rh-HGF including a phase I II study of patients with fulminant hepatitis FH or late-onset hepatic failure LOHF in order to examine the safety pharmacokinetics and clinical efficacy of this molecule. Methods Potential adverse effects identified through preclinical safety tests with rh-HGF include a decrease in blood pressure BP and an increase in urinary excretion of albumin. Therefore we further investigated the effect of rh-HGF on circulatory status and renal toxicity in preclinical animal studies. In a clinical trial 20 patients with FH or LOHF were evaluated for participation in this clinical trial and four patients were enrolled. Subjects received rh-HGF mg m2 day intravenously for 12 to 14 days. Results We established an infusion method to avoid rapid BP reduction in miniature swine and confirmed reversibility of renal toxicity in rats. Although administration of rh-HGF moderately decreased BP in the participating subjects this BP reduction did not require cessation of rh-HGF or any vasopressor therapy BP returned to resting levels after the completion
