Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Overall Number of Participants by the Number of Serious Adverse Events Reported Per Participant	The number of participants with serious adverse events was counted in the four following categories for number of events reported per participant: greater than or equal to (=) 1, 1, greater than (>) 1, or 0 serious adverse events. Participants with multiple occurrences of events (the =1 and >1 serious adverse event categories) were only counted once per category.	From Baseline until end of study (up to approximately 3 years)
