Outcome

Type Measure Description Time frame Safety issue
Primary Number of Subjects With Adverse Events (AEs) and Serious Adverse Events (SAEs) Adverse event = any untoward medical occurrence in a subject administered study medication regardless of causality including abnormal test findings, clinically significant signs/symptoms, changes in physical examination findings, hypersensitivity, progression/worsening of underlying disease, and exposure in utero. Serious adverse event = any untoward medical occurrence at any dose that resulted in death, was life-threatening, required inpatient hospitalization or prolongation of hospitalization, or resulted in persistent or significant disability/incapacity or congenital anomaly/birth defect. Baseline up to 116 Weeks
