An AE is any untoward medical occurrence in a clinical study participant, temporally associated with the use of a study intervention, whether or not considered related to the study intervention. SAE was defined as any untoward medical occurrence that, at any dose, results in death, was life-threatening, requires inpatient hospitalization or prolongation of existing hospitalization, results in persistent or significant disability/incapacity, is a congenital anomaly/birth defect and other situations according to medical or scientific judgement.

Blood samples were collected to analyze the hematology parameters: platelet count, leukocyte count, neutrophils, lymphocytes, monocytes, eosinophils and basophils. Baseline for treatment A was defined as the latest pre-dose assessment with a non-missing value, including those from unscheduled visits (Day -1), before the dose of Treatment A. Change from Baseline was calculated by subtracting the Baseline value from the post-dose visit value.

Population: Safety Population. Only those participants with data available at the specified time points were analyzed.

Blood samples were collected to analyze the chemistry parameters: amylase and lipase. Baseline for treatment C was defined as the latest pre-dose assessment with a non-missing value, including those from unscheduled visits (Day 20), before the dose of Treatment C. Change from Baseline was calculated by subtracting the Baseline value from the post-dose visit value.

Pulse rate was measured in the supine position after at least 5 minutes of rest for the participant in a quiet setting without distractions. Baseline for treatment C was defined as the latest pre-dose assessment with a non-missing value, including those from unscheduled visits (Day 21, Pre-Dose), before the first dose in Treatment C. Change from Baseline was calculated by subtracting the Baseline value from the post-dose visit value.
