Clinical Trial Summary

The purpose of the study was to evaluate the safety of rHSA/EPO to healthy subjects and to investigate the pharmacokinetic characteristics of rHSA/EPO in healthy subjects, and to obtain preliminary pharmacokinetic parameters.

Description:

This experiment was a single-center clinical study with randomized, open, positive drug control and single dose increment. The test group will be conducted in the order of incremental dose from 150μg to 1200μg 5 dose groups, with 1 positive control groups (EPIAO). After 7 days of administration, the researchers looked at the drug safety tolerance of the test to determine whether to proceed with the next higher dose group test.
