Laborértékek

• As determined by the researchers, the subjects have other factors that may force them to terminate the study halfway, such as non-compliance with the protocol, suffering from other serious diseases (including mental disorders) that require concurrent treatment, having severely abnormal laboratory test values of clinical significance, family or social factors that may affect the safety of the subjects or the collection of trial data, etc.
