ListOutcomeTime frameDescription
PrimaryNumber of Participants With Non-serious Treatment-emergent Adverse Events (Non-STEAEs) and Serious Treatment-emergent Adverse Events (STEAEs)Up to 10 years and 11 months
AE was defined as any untoward medical occurrence in participant or clinical investigation participant,temporally associated with use of medicinal product, whether or not considered related to medicinal product.SAE was defined as any untoward medical occurrence that, at any dose: results in death,is life threatening, requires hospitalization or prolongation of existing hospitalization,results in disability or incapacity,or is congenital anomaly or birth defect, important medical events that may not immediately life threatening or result in death or hospitalization but may jeopardize participant or may require medical or surgical intervention as per medical or scientific judgement or associated with drug-induced liver injury.TEAE is any event that was not present prior to initiation of study treatment or any event already present that worsens in either intensity or frequency following exposure to study treatment. TEAEs which were not serious TEAEs were considered as non serious TEAEs.
PrimaryChange From Baseline in Liver Function Parameters: Alanine Amino Transferase (ALT), Aspartate Amino Transferase (AST), Gamma Glutamyl Transferase (GGT), Total BilirubinBaseline (Day 1) and up to 10 years and 11 months
Blood samples were collected from participants for analysis of following clinical chemistry parameters: ALT, AST, GGT, total bilirubin. Baseline was the last value recorded prior to start of study treatment from AMB112529. Change from Baseline was calculated by subtracting the Baseline value from the end of study post-dose visit value.
PrimaryChange From Baseline in Chemistry Parameters: Calcium, Chloride, Carbon Dioxide (CO2) Content, Glucose, Potassium, Magnesium, Sodium, Phosphorus Inorganic, Blood Urea Nitrogen (BUN)Baseline (Day 1) and up to 10 years and 11 months
Blood samples were collected from participants for analysis of following clinical chemistry parameters: Calcium, chloride, CO2 content, glucose, potassium, magnesium, sodium, phosphorus inorganic, and BUN. Baseline was the last value recorded prior to start of study treatment from AMB112529. Change from Baseline was calculated by subtracting the Baseline value from the end of study post-dose visit value.
PrimaryChange From Baseline in Chemistry Parameters: Alkaline Phosphatase (ALP), Creatine Kinase (CK), Lactate Dehydrogenase (LDH)Baseline (Day 1) and up to 10 years and 11 months
Blood samples were collected from participants for analysis of following clinical chemistry parameters: ALP, CK, LDH. Baseline was the last value recorded prior to start of study treatment from AMB112529. Change from Baseline was calculated by subtracting the Baseline value from the end of study post-dose visit value.
PrimaryChange From Baseline in Chemistry Parameters: Creatinine, Uric AcidBaseline (Day 1) and up to 10 years and 11 months
Blood samples were collected from participants for analysis of following clinical chemistry parameters: Creatinine, uric acid. Baseline was the last value recorded prior to start of study treatment from AMB112529. Change from Baseline was calculated by subtracting the Baseline value from the end of study post-dose visit value.
PrimaryChange From Baseline in Chemistry Parameters: Albumin, Total ProteinBaseline (Day 1) and up to 10 years and 11 months
Blood samples were collected from participants for analysis of following clinical chemistry parameters: Albumin, total protein. Baseline was the last value recorded prior to start of study treatment from AMB112529. Change from Baseline was calculated by subtracting the Baseline value from the end of study post-dose visit value.
PrimaryChange From Baseline in Hematology Parameters: Hemoglobin and Mean Corpuscle Hemoglobin Concentration (MCHC)Baseline (Day 1) and up to 10 years and 11 months
Blood samples were collected from participants for analysis of following hematology parameters: Hemoglobin and MCHC. Baseline was the last value recorded prior to start of study treatment from AMB112529. Change from Baseline was calculated by subtracting the Baseline value from the end of study post-dose visit value.
PrimaryChange From Baseline in Hematology Parameters: HematocritBaseline (Day 1) and up to 10 years and 11 months
Blood samples were collected from participants for analysis of following hematology parameters: Hematocrit. Baseline was the last value recorded prior to start of study treatment from AMB112529. Change from Baseline was calculated by subtracting the Baseline value from the end of study post-dose visit value.
PrimaryChange From Baseline in Hematology Parameters: Basophils, Eosinophils, Lymphocytes, Monocytes, Total Neutrophils, White Blood Cells (WBC), Platelet CountBaseline (Day 1) and up to 10 years and 11 months
Blood samples were collected from participants for analysis of following hematology parameters: Basophils, eosinophils, lymphocytes, monocytes, total neutrophils, WBC, platelet count. Baseline was the last value recorded prior to start of study treatment from AMB112529. Change from Baseline was calculated by subtracting the Baseline value from the end of study post-dose visit value.
PrimaryChange From Baseline in Hematology Parameter: Mean Corpuscle HemoglobinBaseline (Day 1) and up to 10 years and 11 months
Blood samples were collected from participants for analysis of following hematology parameter: Mean Corpuscle Hemoglobin. Baseline was the last value recorded prior to start of study treatment from AMB112529. Change from Baseline was calculated by subtracting the Baseline value from the end of study post-dose visit value.
