Change in Mean Numerical Rating Scale (NRS) Score From Baseline to Last 5 Days of Treatment
Délai: 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

Délai |

|
Daily Numerical Rating Scale (NRS) Pain Scores and Change From Baseline Over Time to Day 28.
Délai: 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
Délai: 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
Délai: 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.
Délai: 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.
Délai: 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.
Délai: 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.
Délai: 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.
Délai: 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.
