Abstract:
This study was performed for the purpose to evaluate the effect of activin A/BMP-2 chimera (AB204) on cardiovascular system and toxicological effect in beagle dogs. When administered AB204 at the dose of 0.32 mg/kg via intravenous injection in beagle dogs, there were no changes in systolic, diastolic and mean blood pressure as well as in pulse rate, in addition that there were no differences in ORS complex, PR interval, R-R interval, QT interval and QTcV interval on the electrocardiography. Also, when administered AB204 at the doses of 0.25 and 0.5 mg/kg/day via repetitive intravenous injection for 2 weeks, it did not cause any significant changes in general symptoms, weight, food intake, ophthalmologic abnormality, urine, hematology, serum biochemistry, organ weight and autopsy values. Therefore, AB204 did not affect cardiovascular functions including blood pressure, pulse rate and ECG, when administered at the dose of ≤0.32 mg/kg via single intravenous injection in male beagle dogs. When it was administered at the dose of 0.5 mg/kg repetitive intravenous injection for 2 weeks, it did not show any toxicity.
