主要结果指标

结果测量
措施说明
大体时间
Change in Mean Numerical Rating Scale (NRS) Score From Baseline to Last 5 Days of Treatment
大体时间:From baseline to day 28

Change of mean pain intensity from 5-day baseline to the last 5 days of treatment, measured twice daily with NRS (12 hours recall).

Mean pain intensity for 5-day baseline period (evening Day -6 to moning Day-1) and mean pain intensity for last 5 days on treatment (ie, last dose day and the 4 preceding calendar days) was calculated based on the numerical rating scale (NRS)(0-10). 0=No pain, 10=Worst pain imaginable.

From baseline to day 28

次要结果测量

结果测量
措施说明
大体时间
Daily Numerical Rating Scale (NRS) Pain Scores and Change From Baseline Over Time to Day 28.
大体时间:From baseline to 28 days
Mean pain intensity per day (mean of morning and evening NRS values) and change from baseline were calculated for each study day. Baseline value= mean pain intensity for the 5-day baseline period. NRS scale (0- 10) where 0= No pain and 10= Worst pain imaginable.
From baseline to 28 days
Number of Patients With >=30% Reduction From Baseline in Numerical Rating Scale (NRS) Pain Intensity Score at Day 28
大体时间:28 days
Pain intensity score reduction=(change from baseline at D28/baseline)*100 Responder= pain intensity score reduction ≥30% (yes/no)? Responder rate= (no. of responders/total no. of patients)*100
28 days
Number of Patients With >=50% Reduction From Baseline in Numerical Rating Scale (NRS) Pain Intensity Score at Day 28
大体时间:28 days
Pain intensity score reduction= (change from baseline D28/baseline)*100 Responder=pain intensity score reduction ≥50% (Yes/No)? Responder rate= (no. of responders/total no. of patients)*100
28 days
Number of Patients With Patient Global Impression of Change (PGIC) Score of at Least "Much Improved" at Day 28.
大体时间:28 days

Patient Global Impression of Change (PGIC) scale ranges from 1-7, where 1= Very much improved and 7= Very much worse.

Responder= Patient with a response of "much improved" or "very much improved" Responder rate= (no. of responders/total no. of patients)*100

28 days
Change in McGill Pain Questionnaire Short Form (MPQ-SF) Sensory Index From Baseline to Day 28.
大体时间:From baseline to day 28.

Sensory index= sum of the intensity scale values of the words chosen for the descriptors 1-11 in the questionnaire. Range of scores for the sensory index= 0-33 (higher score represents a worse condition).

Change from baseline (measured prior to randomization) to Day 28 was calculated.

From baseline to day 28.
Change in McGill Pain Questionnaire Short Form (MPQ-SF) Affective Index From Baseline to Day 28.
大体时间:From baseline to day 28.

Affective index= sum of the intensity scale values of the words chosen for the descriptors 12-15 in the questionnaire. Range of scores for the affective index=0-12 (higher score represents a worse condition).

Change from baseline (measured prior to randomization) to Day 28 was calculated.

From baseline to day 28.
Change in Brief Pain Inventory-Short Form (BPI-SF) Pain Severity From Baseline to Day 28.
大体时间:From baseline to day 28..
Change from baseline (measured prior to randomization) to Day 28 was calculated for the pain severity (mean of 4 intensity items). Each intensity item is recorded on a Numerical rating Scale (NRS) 0-10, where 0=No pain and 10= The worst pain.
From baseline to day 28..
Change in Brief Pain Inventory-Short Form (BPI-SF) Pain Interference From Baseline to Day 28.
大体时间:From baseline to 28 days
Change from baseline (measured prior to randomization) to Day 28 was calculated for pain interference (mean of 7 interference items). Each interference item is recorded on a Numerical Rating Scale (NRS 0-10), where 0= No interference and 10= Interferes completely.
From baseline to 28 days
