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 is defined as any serious adverse event that, at any dose which results in death, is life-threatening, requires inpatient hospitalization or prolongation of existing hospitalization, results in persistent or significant disability/incapacity, is a congenital anomaly/birth defect, other situations as per investigator's medical or scientific judgment.

Blood samples were collected for analysis of chemistry parameters. PCI ranges were \>=2\*Upper limit of normal (ULN) units per liter (U/L)(Alanine Aminotransferase \[ALT\]), \>=2\*ULN (U/L) (Aspartate Aminotransferase (\[AST\]), \>=2\*ULN (Alkaline Phosphatase \[ALP\]) (U/L), \>=1.5\*ULN (micromoles per liter) (bilirubin), \<2 or \>2.75 millimoles/liter (L) (mmol/L)(calcium), \<3 or \>11 mmol/L (glucose), \<3 or \>5.5 mmol/L (potassium), \<130 or \>150 mmol/L (sodium),\<50 or \>85 grams/liter (protein). Participants were counted in worst case category that their value changes to (low, within \[w/in\] range or no change \[NC\], or high), unless there is no change in their category. Participants whose laboratory value category was unchanged (e.g., High to High), or whose value became within range, are recorded in 'To within Range No Change' category. Participants were counted twice if participant had values that changed 'To Low' and 'To High', so percentages may not add to 100 percentage (%).
Blood samples were collected for analysis of creatinine. Participants were counted under increase of PCI if they had change from Baseline \> 44.2 micromoles per Liter for any post Baseline assessment. Participants who did not meet this PCI criteria are counted as within (w/in) range.
Blood samples were collected for analysis of chemistry parameters. PCI range for Urea: High \>10.5 mmol/L. Participants were counted in worst case category that their value changes to (within \[w/in\] range or no change \[NC\], or high), unless there is no change in their category. Participants whose laboratory value category was unchanged (e.g., High to High), or whose value became within range, are recorded in 'To within Range No Change' category.
Blood samples were collected for analysis of hematology parameters. PCI ranges were \>1\*10\^9 cell per liter (cells/L) (eosinophils), \<0.2 or \>0.54 proportion of red blood cells in blood (hematocrit), \<80 or \>180 grams per liter(g/L) (hemoglobin), \<3 or \>20 x10\^9 cells/L (leukocytes), \<0.8\*10\^9 cells/L (lymphocytes), \<1.5 or \>16\*10\^9 cells/L (neutrophils) and \<100 or \>550\*10\^9 cells/L (platelets). Participants were counted in worst case category that their value changes to (low, within range or no change or high), unless there is no change in their category. Participants whose laboratory value category was unchanged (for example \[e.g.\], High to High), or whose value became within range, were recorded in "To within Range or No Change" category. Participants were counted twice if participant has values that changed 'To Low' \& 'To High', so the percentages may not add to 100%.
Vital signs included diastolic blood pressure (DBP), systolic blood pressure (SBP), pulse rate (PR), body temperature, respiratory rate (RR) and were measured after resting for at least 5 minutes in semi-supine position. PCI ranges were, SBP (millimeters of mercury\[mmHg\]): \<85 (low) or \>160 (high), DBP (mmHg): \<45 (low) or \>100 (high), heart rate (beats per minute): \<40 (low) or \>110 (high), respiration rate (breaths per minute):\<=8 (low) or \>20 (high) and body temperature (degrees Celsius) \<=35.5 (low) or \>38.0 (high). Participants were counted in worst case category that their value changes to (low, within range or no change, or high), unless there is no change in their category. Participants whose laboratory value category was unchanged (e.g., High to High), or whose value became within range, are recorded in 'To W/in Range No Change' category. Participants were counted twice if participant had values that changed 'To Low' and 'To High', so percentages may not add to 100%.
Twelve lead ECG was obtained using an ECG machine that automatically calculated the heart rate and measured QTc, PR, QRS intervals. Abnormal findings were categorized as clinically significant and not clinically significant. Clinically significant abnormal findings are those which are 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.
A full physical examination was performed which included, at a minimum, assessments of the Skin, Cardiovascular, Respiratory, Gastrointestinal and Neurological systems.
