Changes in hematology and serum biochemistry after treatment of recombinant human erythropoietin (rHuEPO, HM10760) were screened in 4 male cynomolgus monkeys (Macaca fascicularis). Four monkeys, composed of a treatment group of HM10760 and a positive control group of Aranesp^(R}, were subcutaneously administered at same dose of 100{mu}g/kg. Both groups did not show any change in body weights and food consumption for 4 weeks compared with those of pretreatment. Both groups did not show any change in total leukocyte count (WBC) and platelet count, while both groups showed increased platelet distribution width (PDW) percentage in HM10760 group during a period from day 5 to day 59 and in Aranesp^(R} group during a period from day 9 to day 26. Both groups showed increases in red blood cells (RBC), hemoglobin (HGB), and hematocrit (HCT) approximately 10 days after treatment compared with those of pretreatment (day 0). The increased levels of RBC, HGB, and HCT were much higher in HM10760 than in Aranesp^(R} by the increases of 3.2%{sim}12.5% for RBC, 3.8%{sim}17.1% for HCT, and 1.85%{sim}11% for HGB. Both groups showed increases in red cells distribution width (RDW) and reticulocyte (RET) compared with those of pretreatment, showing the highest peak from day 9. The increased level of RET lasted up to day 14 in Aranesp^(R} group, while it lasted up to day 23 in HM10760 group. The increased level of RDW lasted up to day 59, it was much higher in HM10760 by the increase of 10.1%{sim}17.6% than in Aranesp^(R} group. In serum biochemistry, both groups showed a decrease in chloride level compared with those of pretreatment. These findings indicated that HM10760 increased RBC, HGB, HCT, RDW, and RET compared with those of pretreatment, and the increased levels were much higher in HM10760 than in Aranesp^(R}.
