[An early clinical study of Z-100 in leukopenia caused by radiotherapy]

The clinical efficacy of Z-100 for the treatment of leukopenia caused by radiotherapy for malignant tumors was evaluated in an early clinical study using three doses, 2, 10 and 20 micrograms. According to the evaluation by investigators and time-course of WBC, the highest effective rate was achieved by 20 micrograms. Adverse reactions occurred in all groups, but there were no serious or clinically relevant reactions. These results suggested that Z-100 is clinically useful for the treatment of leukopenia caused by radiotherapy.
