Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Patient Diary-derived Numeric Rating Scale (NRS) Pain Intensity Change From Baseline to Week 12 or Final Visit of the Double-blind Phase | Baseline, Week 12 | Participants rate their pain intensity on a numeric rating scale (NRS), where 0=no pain and 10=worst possible pain, in a daily diary. At Week 12 (or final visit), all measurements during the preceding week are averaged, and the mean change from the mean score at baseline is calculated. |

Outcome results
Patient Diary-derived Numeric Rating Scale (NRS) Pain Intensity Change From Baseline to Week 12 or Final Visit of the Double-blind Phase
Participants rate their pain intensity on a numeric rating scale (NRS), where 0=no pain and 10=worst possible pain, in a daily diary. At Week 12 (or final visit), all measurements during the preceding week are averaged, and the mean change from the mean score at baseline is calculated.
Time frame: Baseline, Week 12
Population: Intent to treat population defined as all patients randomized to the Double-blind phase who received at least one dose of randomized study medication.
