A self-reported scale that measures the severity of pain based on the average pain experienced over the past 24 hours. The severity scores range from 0 (no pain) to 10 (pain as severe as you can imagine). The overall change is based on the estimated main treatment effect. The Least Squares (LS) Mean Value was adjusted for treatment, investigator, visit, baseline, treatment*visit interaction, and baseline*visit interaction.

All randomized participants with a baseline and at least 1 post-baseline result.

The MADRS is a rating scale for severity of depressive mood symptoms. The MADRS has a 10-item checklist. Items are rated on a scale of 0-6, for a total score range of 0 (low severity of depressive symptoms) to 60 (high severity of depressive symptoms). The Least Squares (LS) Mean Value was adjusted for treatment, investigator, visit, baseline, treatment*visit interaction, and baseline*visit interaction.

All randomized participants with a baseline and at least 1 post-baseline result.

SDS is completed by participant; used to assess effect of the participant's symptoms on their work/social/family life. Total scores range from 0 to 30; higher values indicate greater disruption in the participant's work/social/family life. Each item score ranges from 0 to 10 with higher values indicating greater disruption in the participant's work/school life (item 1), social life/leisure activities (item 2), or family life/home responsibilities (item 3). The LS Mean Value was adjusted for treatment, investigator, visit, baseline, treatment*visit interaction, and baseline*visit interaction.

All randomized participants with a baseline and at least 1 post-baseline result.

The Montgomery Asberg Depression Rating Scale (MADRS) is a rating scale for severity of depressive mood symptoms. The MADRS has a 10-item checklist. Items are rated on a scale of 0-6, for a total score range of 0 (low severity of depressive symptoms) to 60 (high severity of depressive symptoms). Remission is defined as achieving a MADRS total score ≤12.

All randomized participants with a post-baseline result, Last Observation Carried Forward (LOCF).

The Montgomery Asberg Depression Rating Scale (MADRS) is a rating scale for severity of depressive mood symptoms. The MADRS has a 10-item checklist. Items are rated on a scale from 0-6, for a total score range of 0 (low severity of depressive symptoms) to 60 (high severity of depressive symptoms). Remission is defined as achieving a MADRS total score ≤12 at the last 2 nonmissing consecutive visits (for example, visit 3 [week 1] and visit 4 [week 2], or visit 4 [week 2] and visit 5 [week 4], or visit 5 [week 4] and visit 6 [week 8]).

All randomized participants with a baseline and at least 1 post-baseline value.

The MADRS is a rating scale for severity of depressive mood and symptoms. The MADRS has a 10-item checklist. Items are rated on a scale from 0-6, for a total score range of 0 (low severity of depressive symptoms) to 60 (high severity of depressive symptoms). The Least Squares (LS) Mean Value was adjusted for treatment, investigator, visit, baseline, treatment*visit interaction, and baseline*visit interaction.

Measures pain severity and interference on function. Severity scores: 0 (no pain) to 10 (severe pain) on each question. Interference scores: 0 (does not interfere) to 10 (completely interferes) on each question assessing interference of pain in past 24 hours for general activity, mood, walking ability, normal work, relations with other people, sleep, and enjoyment of life. Average interference=average of nonmissing scores of individual interference items. LS Mean Value adjusted for treatment, investigator, visit, baseline, treatment*visit interaction, and baseline*visit interaction.

All randomized participants with a baseline and at least 1 post-baseline result.

A scale that measures the participant's perception of improvement at the time of assessment compared with the start of treatment. The score ranges from 1 (very much better) to 7 (very much worse). The Least Squares (LS) Mean Value was adjusted for treatment, investigator, visit, and treatment*visit interaction.

All randomized participants with a baseline and at least 1 post-baseline result.

The C-SSRS captures occurrence, severity, and frequency of suicide-related thoughts and behaviors. Number of participants with suicidal behaviors, ideations, and acts are provided. Suicidal behavior: a "yes" answer to any of 5 suicidal behavior questions: preparatory acts or behavior, aborted attempt, and completed suicide. Suicidal ideation: a "yes" answer to any 1 of 5 suicidal ideation questions, which includes wish to be dead, and 4 different categories of active suicidal ideation. Suicidal acts: a "yes" answer to actual attempt or completed suicide.

All randomized participants with at least 1 post-baseline C-SSRS result.

Laboratory assessment of ALT/SGPT during the double-blind treatment phase. Normal ALT/SGPT ranges for males are 6.00 units per liter (U/L) (low) to 43.00 U/L (high). Normal ALT/SGPT ranges for females are 6.00 U/L (low) to 34.00 U/L (high).

All randomized participants with a normal baseline (respective to the specified direction) and at least 1 post-baseline result.

The change from baseline in pulse rate at week 8 is the primary analysis. For the primary analysis of pulse rate, the Least Squares (LS) Mean Value was adjusted for treatment, investigator, baseline, treatment*visit interaction, and baseline*visit interaction.

The change from baseline in pulse rate up to week 8 is the secondary analysis. The LS Mean Value was adjusted for treatment, investigator, and baseline.

Primary analysis: All randomized participants with a baseline and at least 1 post-baseline result.

Secondary analysis: Intention-to-treat population (ITT) with nonmissing baseline value and at least 1 nonmissing post-baseline value, LOCF.

The change from baseline in SBP and DBP at week 8 is the primary analysis. For the primary analysis of SBP and DBP, the Least Squares (LS) Mean Value was adjusted for treatment, investigator, baseline, treatment*visit interaction, and baseline*visit interaction.
