Preclinical safety evaluation of body protective compound-157, a potential drug for treating various wounds

BPC157 displays protective activity in various organs and tissues. This report presents preclinical toxicity studies with BPC157 in mice, rats, rabbits and dogs. The single-dose toxicity study did not show any test-related effects that could be attributed to the test article. In repeated-dose toxicity evaluations, BPC157 was well tolerated in dogs, with no abnormal changes between the BPC157-treated groups and the solvent control group, with the exception of a decrease in creatinine level at a dose of 2 mg/kg but not at lower doses. The animals recovered spontaneously after 2 weeks of withdrawal. This may be due to the pharmacological activity of BPC157. A local tolerance test showed that the irritation caused by BPC157 was mild. BPC157 also showed no genetic or embryo-fetal toxicity. In summary, BPC157 was well tolerated and did not cause any serious toxicity in mice, rats, rabbits and dogs. These preclinical safety data contribute to the initiation of an ongoing clinical study. Based on the stability and protective effect of BPC157, which has been widely reported, BPC157 may have a better application prospect than the widely used cytokine drugs in wound therapy.
