The subacute toxicity was investigated in Sprague-Dawley rats orally treated with KDRD-010 at the doses of 0.056, 0.28, and 1.4 g/kg for one month. There were no clinical signs and pathological changes compared with control group. Body weights were not significantly changed between control and treatment groups. In hematological and biochemical serum parameters, all mean values appear to be within the normal range. In pathological examinations, hemorrhages of lung was observed in one male rat at low dose group and one female rat at high dose group of KDRD-010, but it was not considered to be caused by KDRD-010. These results suggest that KDRD-010 dose not induce any significant subacute oral toxicities in Sprague-Dawley rats.

This study was carried out to investigate the acute toxicity of KDRD-010 in Sprague-Dawley rats. KDRD-010 was administratered orally at a dose level of 26, 78, 233, 700, and 2,100 mg/kg. In this study, we daily examined number of deaths, clinical signs, body weights, and pathological examinations for 14 days after administration of KDRD-010. The results indicate that KDRD-010 did not show any toxic effect in rats and oral $LD_50$ value was over 2,100 mg/kg in Sprague-Dawley rats.
