Arm Description

Per the protocol, patients randomized to the duloxetine group were to receive duloxetine for the entire 13-week acute treatment period. Patients were to start at a 30 mg daily (QD) dose of duloxetine for 1 week, then increase to 60 mg QD of duloxetine for the following 12 weeks. However, due to a study drug labeling error, patients randomized to this group received 30 mg of duloxetine for the initial 1-week, but received placebo instead of receiving 60 mg QD of duloxetine for the next 12 weeks. The resulting unintended, mixed treatment group was labeled as DLX30-PLA throughout this document. Per protocol, the last week of the study (week 14) was intended to be a 1-week taper period. Patients in this treatment group were to receive 30 mg QD of duloxetine during that week, and that did occur per protocol.

Per the protocol, patients randomized to the placebo group were to receive placebo for the entire 13-week acute treatment period. Patients were to start on placebo for the first week, then continue on placebo for the following 12 weeks. However, due to a study drug labeling error, patients in this group received placebo for the initial 1-week, but received 60 mg QD of duloxetine instead of receiving placebo for the next 12 weeks. The resulting unintended, mixed treatment group was labeled as PLA-DLX60 throughout this document. Per protocol, the last week of the study (week 14) was intended to be a 1-week taper period. Patients in this treatment group were to receive placebo that week, and that did occur per protocol.

Outcomes

Primary Outcome Measures

Change From Baseline to 13 Week Endpoint (Baseline Observation Carried Forward [BOCF]) in Brief Pain Inventory (BPI) "24-Hour Average Pain" Item (Question 3) of the BPI-Modified Short Form Score
A self-reported measure of the severity of pain based on the average pain over 24-hours. Severity scores range from 0 (no pain) to 10 (pain as severe as you can imagine). BOCF endpoint was defined as the baseline value for participants discontinued during acute phase, and defined as the last non-missing observation in the treatment phase for all other randomized participants. Due to the nature of a study drug labeling error which led to a treatment crossover (see Arms), data from protocol-defined treatment groups were compromised. The results from each mixed-treatment group are presented.

Secondary Outcome Measures

Number of Participants With Suicidal Behaviors and Ideations From the Columbia Suicide Severity Rating Scale
C-SSRS: scale capturing occurrence, severity, and frequency of suicide-related thoughts and behaviors. Number of patients with suicidal behaviors and ideations are provided. Suicidal behavior: a "yes" answer to any of 5 suicidal behavior questions: preparatory acts or behavior, aborted attempt, interrupted attempt, actual attempt, and completed suicide. Suicidal ideation: a "yes" answer to any one of 5 suicidal ideation questions, which includes wish to be dead, and 4 different categories of active suicidal ideation.
Mean Change From Baseline to Endpoint (13 Week) in Patient's Global Impressions of Improvement Score
A scale that measures the patient'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). Due to the nature of a study drug labeling error and the resultant treatment crossover (see Arms), the data from both protocol-defined treatment groups were compromised, and the intended comparisons for differences between those treatment groups are considered unevaluable. Secondary efficacy results from the 2 mixed-treatment groups are not presented.
Mean Change From Baseline to Endpoint (13 Week) in Western Ontario McMaster Universities (WOMAC) Index Score
The WOMAC index (pain, stiffness, physical function subscales) was completed by the patient. The index has 24 questions. Each question is answered using a 5-point Likert scale (0 to 4). The Total score has a range from 0 (none) to 96 (extreme). Due to the nature of a study drug labeling error and the resultant treatment crossover (see Arms), data from both protocol-defined treatment groups were compromised, and the intended comparisons for differences between those treatment groups are considered unevaluable. Secondary efficacy results from the 2 mixed-treatment groups are not presented.
Mean Change of Total Score From Baseline to Endpoint (13 Week) of Brief Pain Inventory-Severity (BPI-S) Scale
Self-reported scale measuring pain severity. Severity scores range from 0 (no pain) to 10 (pain as severe as you can imagine). Four questions assess worst pain, least pain, and average pain in the past 24 hours, and pain right now. Total score ranges from 0-40. Due to the nature of a study drug labeling error and resultant treatment crossover, data from both protocol-defined treatment groups were compromised, and the intended comparisons for differences between those treatment groups are considered unevaluable. Secondary efficacy results from the 2 mixed-treatment groups are not presented.
Mean Change of Total Score From Baseline to Endpoint (13 Week) in Brief Pain Inventory- Interference Score
Interference scores range from 0 (does not interfere) to 10 (completely interferes) on 7 questions assessing interference of pain for general activity, mood, walking ability, normal work, relations with others, sleep, and enjoyment of life. Total score ranges from 0-70. Due to the nature of study drug labeling error and resultant treatment crossover, data from both protocol-defined treatment groups were compromised, and intended comparisons for differences between those treatment groups are considered unevaluable. Secondary efficacy results from the 2 mixed-treatment groups are not presented.
Mean Change of Total Score From Baseline to Endpoint (13 Week) in Clinical Global Impressions of Severity (CGI-S)
Measures severity of illness at the time of assessment compared with start of treatment. Scores range from 1 (normal, not at all ill) to 7 (among the most extremely ill patients). Due to the nature of a study drug labeling error and the resultant treatment crossover (see Arms), the data from both protocol-defined treatment groups were compromised, and the intended comparisons for differences between those treatment groups are considered unevaluable. Secondary efficacy results from the 2 mixed-treatment groups are not presented.
Mean Change of Total Score From Baseline to Endpoint(13 Week) in Intermittent and Constant Osteoarthritis Pain: Knee Version
An 11-item questionnaire to individually and jointly assess intermittent and constant pain. Questions assess intensity and impact of pain on activity and emotion. Each item is scored from 0 to 4; higher values indicate higher severity. Total Pain score ranges from 0-44. Due to the nature of study drug labeling error and resultant treatment crossover, data from both protocol-defined treatment groups were compromised, and intended comparisons for differences between those treatment groups are considered unevaluable. Secondary efficacy results from the 2 mixed-treatment groups are not presented.
Mean Change of Total Score From Baseline to Endpoint (13 Week) in Profile of Mood States- Brief Form (BPOMS)
BPOMS measures mood states and has 6 factors: tension-anxiety, depression-dejection, anxiety-hostility, fatigue, confusion, and vigor. Item scores: 0 (not at all) to 4 (extremely). Each factor scores range from 0-20. Total score = sum of all factor scores minus vigor score. Due to nature of study drug labeling error and resultant treatment crossover, data from both protocol-defined treatment groups were compromised, and intended comparisons for differences between those treatment groups are considered unevaluable. Secondary efficacy results from the 2 mixed-treatment groups are not presented.
Mean Change of Total Score From Baseline to Endpoint (13 Week) in European Quality of Life Questionnaire (EQ-5D)
Patients rate their health state in 5 domains: mobility, self-care, usual activities, pain, and mood. Score between 1-3 is generated for each domain which is mapped to single index score. Index ranges between 0-1; higher scores indicate better health perceived by patient. Due to nature of study drug labeling error and resultant treatment crossover, data from both protocol-defined treatment groups were compromised, and intended comparisons for differences between those treatment groups are considered unevaluable. Secondary efficacy results from the 2 mixed-treatment groups are not presented.
Mean Change From Baseline to Endpoint (13 Week) in 36-item Short-Form Health Survey
Self-reported questionnaire with 36 questions covering 8 health domains. Each domain is scored by summing the individual items and transforming the scores into a 0 to 100 scale, with higher scores indicating better health status or functioning. Due to the nature of a study drug labeling error and the resultant treatment crossover (see Arms), the data from both protocol-defined treatment groups were compromised, and the intended comparisons for differences between those treatment groups are considered unevaluable. Secondary efficacy results from the 2 mixed-treatment groups are not presented.
