Participants were assessed through each laboratory variables for any significant abnormalities. Hematology assessments included white blood cell count, red blood cell count, hemoglobin, hematocrit, mean corpuscular volume, mean corpuscular hemoglobin and others. Clinical chemistry assessment included testing levels of sodium, potassium, urea, creatinine, albumin, calcium, glucose (fasting) and others. Urinalysis assessment included glucose, protein, blood and microscopy (if positive for blood or protein).
Percentage of Participants With Adverse Events (AEs).	SAEs were recorded from the signing of informed consent and AEs were recorded from randomisation until the final follow-up visit.	An AE is the development of an undesirable medical condition or the deterioration of a pre-existing medical condition following or during exposure to a pharmaceutical product, whether or not considered causally related to the product. The term AE is used generally to include any AE whether serious or non-serious. A serious AE (SAE) is an AE that fulfills one or more of the following criteria: results in death, is immediately life-threatening; requires in-patient hospitalization or prolongation of existing hospitalization; results in persistent or significant disability or incapacity or substantial disruption of the ability to conduct normal life functions; is a congenital abnormality or birth defect; is an important medical event that may jeopardize the participant or may require medical intervention to prevent one of the outcomes listed above.
