An acute toxicity study of recombinant human interferon αA (LBD-007) in Sprague-Dawley rats

Abstract

The acute toxicity of a recombinant human interferon αA (code name: LBD-007) was evaluated in both sexes of Sprague-Dawley rats, 5 weeks old, by the oral, subcutaneous and intravenous routes of administration. Based on the results, LBD-007 was not considered to induce any toxicological effect on the rats in mortalities, clinical findings, body weights and gross findings. It is suggested that LD50 values in rats would be >48 x 108 IU/kg in the study of oral administration and >24 x 108 IU/kg in the study of subcutaneous or intravenous administration.
