Study Endpoints
Primary Endpoints
Number of Participants With Any Serious Adverse Event (SAE) and Any Non Serious Adverse Event
From baseline (Week 0) until 2 weeks after the end of treatment (Week 54)

An adverse event (AE) is any untoward medical occurrence in a participant, temporally associated with the use of medicinal product, which does not necessarily have a causal relationship with the treatment. An SAE is any untoward medical occurrence that, at any dose, results in death, is life-threatening, requires inpatient hospitalization or causes its prolongation, results in persistent or significant disability/incapacity, is a congenital anomaly/birth defect, or is an important medical event. A complete list of all SAEs and AEs experienced in the study can be found in the SAE/AE section.
