An adverse event (AE) is any untoward medical occurrence in a clinical study participant, temporally associated with the use of a study treatment, whether or not considered related to the study treatment. An SAE is defined as any untoward medical occurrence that: results in death, is life-threatening, requires inpatient hospitalization or prolongation of existing hospitalization, results in persistent disability/incapacity, is a congenital anomaly/birth defect, other situations judged by physician. SAEs were collected up to Day 197, but the protocol also allowed investigators to report SAEs occurring after participants had completed the study. This outcome measure includes two SAEs reported after participants had completed the study, occurring on Day 306 and Day 603 following first dose. Safety Population consisted of all randomized participants who have taken at least 1 dose of study treatment.
Blood samples were collected to analyze the hematology parameters: Basophils, Eosinophils, Lymphocytes, Monocytes, Total Neutrophils, Platelet Count and WBC count. Baseline was defined as the pre-dose Day 1 assessment, unless unavailable, in which case it was the latest pre-dose assessment. Change from Baseline was calculated by subtracting the Baseline value from the post-dose visit value.
Blood samples were collected to analyze the hematology parameters: hemoglobin and MCHC. Baseline was defined as the pre-dose Day 1 assessment, unless unavailable, in which case it was the latest pre-dose assessment.

Blood samples were collected for analysis of clinical chemistry parameters. PCI ranges were low: \<30 grams per liter (g/L) (albumin), high: \>44.2 micromoles per liter (µmol/L) increase from Baseline (creatinine), low: \<3 or high: \>9 mmol/L (glucose), low: \<3 or high: \>5.5 mmol/L (potassium), and low: \<130 or high: \>150 mmol/L (sodium). Participants were counted in the worst case category that their value changes to (low, within range or no change, or high), unless there was no change in their category. Participants whose laboratory value category was unchanged (e.g. High to High), or whose value became within range, were recorded in the "To within Range or No Change" category. Participants were counted twice if the participant had values that changed 'To Low' and 'To High', so the percentages may not add up to 100%.

Change from Baseline was calculated by subtracting the Baseline value from the post-dose visit value.
Urine samples were collected for the assessment of potential of hydrogen, specific gravity, glucose, ketones, occult blood and protein by dipstick method. The dipstick test gave results in a semi-quantitative manner, and results for urinalysis parameters: potential of hydrogen, specific gravity, glucose, ketones, occult blood and protein were categorized as 'any increase from Baseline', which imply any increase in their concentrations in the urine sample. Only participants with emergent worst case any increase from Baseline values are presented.
Systolic blood pressure (SBP), diastolic blood pressure (DBP), heart rate (HR) were measured in a seated or semi-supine position after 5 minutes of rest using a completely automated device. PCI ranges were: SBP (increase or decrease from Baseline of \>=40 millimeter of mercury \[mmHg\]), DBP (increase or decrease from Baseline of \>=20 mmHg), and HR (increase or decrease from Baseline of \>=30 beats per minute). Baseline was defined as the pre-dose Day 1 assessment, unless unavailable, in which case it was the latest pre-dose assessment.
Body temperature was measured in a seated or semi-supine position after 5 minutes of rest. Baseline was defined as the pre-dose Day 1 assessment, unless unavailable, in which case it was the latest pre-dose assessment. Change from Baseline was calculated by subtracting the Baseline value from the post-dose visit value.
Twelve lead ECGs were obtained using an ECG machine that automatically calculated the heart rate and measured PR, QRS, QT, and corrected QT intervals. Abnormal findings were categorized as clinically significant and not clinically significant. Clinically significant abnormal findings were those which were not associated with the underlying disease, unless judged by the investigator to be more severe than expected for the participant's condition. Data for number of participants with worst case post-Baseline abnormal ECG findings have been presented.
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. A SAE is defined as any untoward medical occurrence that, at any dose: results in death, is life-threatening, requires inpatient hospitalization or prolongation of existing hospitalization, results in persistent or significant disability/incapacity, congenital anomaly/birth defect, any other situation according to medical or scientific judgment. Safety Population consisted of all randomized participants who received at least one dose of study treatment.
Vital signs were measured in semi-supine position after 5 minutes of rest and included systolic blood pressure (SBP), diastolic blood pressure (DBP), heart rate (HR). Participants were counted in the worst case category that their value changed to low, within range or high, unless there was no change in their category. Participants whose value category was unchanged (e.g., High to High), or whose value became within range, were recorded in the "Within Range or No Change" category. Participants were counted twice if values changed 'To Low' and 'To High', so the percentages were not added up to 100 percent (%). Participants with missing Baseline values were assumed as within range value. PCI ranges were: SBP (lower: \<85, upper: \>160 millimeter of mercury \[mmHg\]); DBP (lower: \<45, upper: \>100 mmHg); HR (lower: \<40, upper: \>110 beats per minute). Baseline was defined as the pre-dose Day 1 assessment, unless unavailable, in which case it was the latest pre-dose assessment.
12-lead ECGs were recorded in semi-supine position using an ECG machine. Number of participants with worst-case clinically significant and not clinically significant abnormal ECG findings have been presented. Clinically significant abnormal laboratory findings were those which were not associated with the underlying disease, unless judged by the investigator to be more severe than expected for the participant's condition.
Blood samples were collected for the analysis of clinical chemistry parameters. Clinical chemistry parameters were summarized according to the National Cancer Institute Common Terminology Criteria for Adverse Events (NCI-CTCAE), version 5.0: Grade 1: mild; Grade 2: moderate; Grade 3: severe; Grade 4: life-threatening or disabling. Higher grade indicates more severity. Clinical chemistry parameters included: total bilirubin, calcium, creatinine and triglycerides.
Blood samples were collected for the analysis of the following hematology parameters: hemoglobin (Hb), lymphocytes (Lympho), platelet count (PC), neutrophil count (Neutro) and White Blood Cell count (WBC). The laboratory parameters were graded according to NCI-CTCAE version 5.0. Grade 1: mild; Grade 2: moderate; Grade 3: severe or medically significant; Grade 4: life-threatening consequences. Higher grade indicates more severity. Baseline was defined as the pre-dose Day 1 assessment, unless unavailable, in which case it was the latest pre-dose assessment. An increase was defined as an increase in CTCAE Grade relative to Baseline Grade.
Urine samples were collected for analysis of blood, glucose, ketones and protein by a dipstick method. The dipstick test gives results in a semi-quantitative manner, and results for urinalysis parameters of urine glucose, protein, blood and ketones can be read as negative (-), trace, 1+, 2+, 3+ indicating proportional concentrations in the urine sample. Baseline was defined as the pre-dose Day 1 assessment, unless unavailable, in which case it was the latest pre-dose assessment. Any increase means any increase to trace, 1+, 2+ or 3+ post-Baseline relative to Baseline. Number of participants with worst case any increase in urinalysis results post-Baseline relative to Baseline has been presented.
Clinical laboratory tests will include clinical chemistry, hematology and urinalysis.
