Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Compare the change from baseline in Numeric Rating Scales(NRS )between HSK16149 and pregabalin at week 4 | Baseline and week 4 | Numeric Rating Scales(NRS )was a 11-point numeric rating scale ( 0\[no pain\] to 10 \[worst possible pain\] |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Compare the response rate between HSK16149 and pregabalin at week 4 (Proportion of subjects whose NRS decreased by ≥30% and≥ 50% from baseline ) | Baseline and week 4 | — |
| Compare the change from baseline in VAS between HSK16149 and pregabalin at week 4 | Baseline and week 4 | VAS, in which the participant rates pain on a 100 mm-long horizontal line, where 0 mm = no pain and 100 mm = worst possible pain |
| Compare the change from baseline in DSIS between HSK16149 and pregabalin at week 4 | Baseline and week 4 | The sleep interference scores on a scale of 0-10, where 0 = pain did not interfere with sleep to 10 = pain completely interfered with sleep. |
