Primary Outcome Measures
NameTimeMethod
Number of Participants With AEs Leading to Study Drug DiscontinuationUp to 30 days after study treatment discontinuation (treatment exposure ranged from 1 to 82 months)

Number of participants with AEs leading to study drug discontinuation was reported.

Number of Participants With Treatment-emergent Adverse Events (TEAEs)Up to 30 days after study treatment discontinuation (treatment exposure ranged from 1 to 82 months)

An adverse event (AE) is any untoward medical occurrence in a participant participating in a clinical study that does not necessarily have a causal relationship with the pharmaceutical/ biological agent under study. TEAEs are those events that started after administration of the first dose and up to safety follow-up visit/end of study, that is, 30 days after the last dose of study medication.

Number of Participants With Treatment-emergent Serious Adverse Events (SAEs)Up to 30 days after study treatment discontinuation (treatment exposure ranged from 1 to 82 months)

A serious adverse event (SAE) is any untoward medical occurrence that at any dose resulting in any of following outcomes: 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, is a suspected transmission of any infectious agent via a medicinal product. Treatment-emergent SAEs were those events that started after administration of the first dose and up to safety follow-up visit/end of study, that is, 30 days after the last dose of study medication.

Number of Participants With Liver Tests AbnormalitiesUp to 30 days after study treatment discontinuation (treatment exposure ranged from 1 to 82 months)

Number of participants with liver tests abnormalities were reported. It included alanine aminotransferase (ALT) or aspartate aminotransferase (AST): \>=3 x Upper limit of the normal range (ULN), \>=3 and \<5 x ULN, \>=5 ULN, and \>=5 and \<8 x ULN, \>= 8 x ULN, and total bilirubin \>=2 x ULN.

Change From Baseline in Pulse Rate at Month 6Baseline and Month 6

Change from baseline in pulse rate at Month 6 was reported.

Change From Baseline in Body Weight at Month 6Baseline and Month 6

Change from baseline in body weight at Month 6 was reported.

Number of Participants With Hemoglobin AbnormalitiesUp to 30 days after study treatment discontinuation (treatment exposure ranged from 1 to 82 months)

Number of participants with hemoglobin abnormalities were reported. It included hemoglobin less than (\<) 80 grams per liter (g/L), hemoglobin \<100 g/L, hemoglobin greater than or equal to (\>=) 80 g/L and \<100 g/L, hemoglobin \<100g/L and a decrease of \>20 g/L from baseline, decrease of \>20 g/L in hemoglobin from baseline, decrease of \>20 g/L and \<=50 g/L in hemoglobin from baseline, and decrease of \>50 g/L in hemoglobin from baseline.

Change From Baseline in Blood Pressure at Month 6Baseline and Month 6

Change from baseline in blood pressure at Month 6 (both systolic blood pressure \[SBP\] and diastolic blood pressure \[DBP\]) was reported.
