A DLT was defined as the occurrence of any of following events that were judged by the study investigator, received at least 80% of the planned cumulative dose during the DLT period of each study intervention and completed the DLT period or additionally, participants who did not receive 80% of the planned total dose of study intervention, but at least 80% dosing of a different dose cohort and finished the DLT period are eligible for the DLT analysis set to be analyzed in the highest dose cohort for which they received 80% of dosing.

An Adverse event (AE) was defined as any unfavorable and unintended sign (including an abnormal laboratory finding), symptom, or disease associated with the use of study drug, whether or not considered related to the study drug or worsening of pre-existing medical condition, whether or not related to study drug. A serious adverse event (SAE) was an AE that resulted in any of the following outcomes: death; life threatening; persistent/significant disability/incapacity; initial or prolonged inpatient hospitalization; congenital anomaly/birth defect or was otherwise considered medically important. The term TEAE is defined as AEs starting or worsening after the first intake of the study drug. TEAEs include both Serious TEAEs and non-serious TEAEs.

Vital sign assessments included assessments of heart rate, diastolic blood pressure, systolic blood pressure, weight, respiratory rate and temperature. Clinical significance was assessed by the investigator. Number of participants who with clinically significant changes from baseline in vital signs were reported.

The laboratory measurements included hematology and biochemistry values were graded with National Cancer Institute - Common Terminology Criteria for Adverse Events (NCI-CTCAE) version 5.0 toxicity grades (where Grade 1 = mild, Grade 2 = moderate, Grade 3 = severe, Grade 4 = life threatening and Grade 5 = death). Number of participants with change from baseline to grade 3 or higher values for the hematology and biochemistry were reported.

ECG parameters included rhythm, heart rate (as measured by RR interval), PR interval, QRS duration, QT intervals, and corrected QT(QTc) intervals. Clinical significance was determined by the investigator. Number of participants with clinically significant change from baseline in 12-lead ECG were reported.
