AE is any untoward medical occurrence in clinical investigation participant, temporally associated with the use of medicinal product, whether or not considered related to the medicinal product. SAE is defined as any untoward medical occurrence that, at any dose results in death, is life-threatening, requires hospitalization or prolongation of existing hospitalization, results in disability/incapacity, is congenital anomaly/birth defect, other situations which involve medical or scientific judgment or is associated with liver injury and impaired liver function. SAEs are subset of AEs. TEAE is an event that emerges during treatment having been absent pretreatment or worsens relative to the pretreatment state. AEs were graded by the investigator according to National Cancer Institute Common Terminology Criteria for AE (NCI-CTCAE) (version 5.0):G1=Mild,G2=Moderate,G3=Severe or medically significant but not immediately life-threatening,G4=Life-threatening consequences,G5=Death related AE.
