Number of adverse events will be monitored throughout the study for all subjects
The following parameters and body systems will be examined and any abnormalities described: height and weight; general appearance; skin; head, ears, eyes, nose, and throat; lungs; heart; lower extremity examination; abdomen; neurologic and lymph nodes. Any clinically significant changes from baseline should be recorded as AEs.
Body temperature, systolic and diastolic cuff blood pressure, pulse rate and pulse oximetry will be measured and any clinically significant changes from baseline should be recorded as AEs.
Changes from baseline of ECG parameters will be evaluated.
Monitoring of the clinically significant laboratory results for sodium, potassium, chloride, bicarbonate/carbon dioxide;, blood urea nitrogen, serum creatinine, glucose, albumin, total protein, alkaline phosphatase, aspartate aminotransferase, alanine aminotransferase, total bilirubin, direct bilirubin, indirect bilirubin, calcium, gamma-glutamyl transferase, creatine kinase
Monitoring of the clinically significant laboratory results for specific gravity, pH, semi-quantitative "dipstick" evaluation of glucose, protein, bilirubin, ketones, leukocytes, blood microscopy and/or culture to be performed if clinically indicated or if urinalysis results positive.
Monitoring of the clinically significant laboratory results for Hemoglobin, hematocrit, white blood cell with differentials (monocytes, eosinophils, basophils, neutrophils, lymphocytes) as an absolute value, red blood cell count, platelet count, C-reactive protein
These events will be monitored throughout the study.
C-SSRS assesses suicidal ideation and behavior risk through a series of questions to assess for suicidal ideation and behavior, the severity and immediacy of the risk, and the level of support the subject may need. C-SSRS Severity of Ideation scores of 4 or 5 are considered SAEs.
