结局指标
主要结局
Change From Baseline to Week 8 in Mean Daily Average Pain Score Assessed by NRS
时间窗: Baseline and week 8
The change from baseline to Week 8 in mean daily average pain score is assessed by NRS. The NRS is a generic instrument for the assessment of pain, consisting of a single question that asks participants to record their daily average pain on an 11-point scale, where 0 anchors "no pain" and 10 "pain as bad as you can imagine". A negative change indicates a reduction/improvement from baseline (i.e. a favorable outcome).
Number of Participants With Adverse Events
时间窗: From first dose of study drug until end of study (up to Day 85)
TEAE was defined as any AE which started, or worsened, after the first dose of study drug through 30 days after the last dose of study drug. AE was considered serious if: resulted in death, was life- threatening, resulted in persistent or significant disability/incapacity or substantial disruption of the ability to conduct normal life functions, resulted in congenital anomaly or birth defect, required inpatient hospitalization or led to prolongation of hospitalization, other medically important events.
