Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Number of Participants Experiencing the Occurrence of at Least One Treatment-emergent Adverse Event (TEAE) During the Evaluation Period From Entry Visit 1 Through End of Treatment (Approximately 6.5 Years).	Adverse events are any untoward medical occurrences in a subject administered study treatment, whether or not these events are related to treatment.	From entry Visit 1 through end of treatment (approximately 6.5 years)
Primary	Number of Participants Experiencing the Occurrence of at Least One Serious Adverse Event (SAE) During the Evaluation Period From Entry Visit 1 Through End of Treatment (Approximately 6.5 Years).	A Serious Adverse Event (SAE) is any untoward medical occurrence that at any dose: Is fatal; Is life-threatening; Results in persistent or significant disability/incapacity; Requires inpatient hospitalization; Prolongs existing inpatient hospitalization; Is a congenital anomaly/birth defect; Is considered to be an important medical event. Such an event may not be immediately life threatening or result in death or hospitalization but may jeopardize the subject or may require intervention to prevent one of the other outcomes listed in the definitions above	From entry Visit 1 through end of treatment (approximately 6.5 years)

Secondary	Average Quality of Life Using the SF-36 Health Survey - Physical Component Summary (PCS) at Baseline.	The SF-36 Health Survey measures health-related quality of life across multiple disease states. It has 36 questions with 8 subscale scores and 2 summary scores: PCS = physical functioning, role-physical, bodily pain, and general health; MCS = vitality, social functioning, role-emotional, and mental health. Scoring is done for both subscores and summary scores. For both, 0 = worst score (or quality of life) and 100 = best score.	Baseline
