Outcomes

Primary Outcome Measures

Time-to-Exit From Current Study Treatment
Time-to-exit was defined as the number of days at which a patient either met the switching criterion [a 2-category change in the Pain Relief Scale (PRS) score in the worsening direction (increasing pain or decreasing pain relief) for 2 consecutive days] or discontinued from the study. The PRS is a 9-point categorical rating scale to assess pain relief in the last 24 hours in which 0 = completely worse and 8 = complete pain relief. Traditional survival models that consider event times (e.g. median survival time) as independent and homogeneous across patients were not suitable for this study.

Secondary Outcome Measures

Time-to-Exit Due to Lack of Efficacy
Time-to-exit due to lack of efficacy was defined as a patient that met the switching criterion (a 2-category change in Pain Relief Scale (PRS) in the worsening direction [increasing pain or decreasing pain relief] for 2 consecutive days) or was discontinued from the current period or study due to lack of efficacy. The PRS is a 9-point categorical rating scale to assess pain relief in the last 24 hours in which 0 = completely worse and 8 = complete pain relief. No patients discontinued from the study due to lack of efficacy.
Exit Status From Current Study Treatment - Yes
Exit status from a current study treatment was categorized as yes or no for patients who exited prior to the 4-week planned duration. This analysis supports the results of the primary analysis. The number of patients exiting (yes) is reported.
Overall Treatment Difference in the LSMeans of the Average of the Last Two Daily Pain Intensity Numerical Rating Scale (PI-NRS)
The Numerical Rating Scale (NRS) is an 11-point categorical rating scale to assess pain intensity (PI-NRS); 0= no pain and 10= worst possible pain. The scale is anchored on the left with "No Pain" and on the right with "Worst Possible Pain." Patients were to complete this assessment at approximately the same time each day during the double-blind treatment period in their e-diary. The overall treatment difference for the Lidoderm (lidocaine patch 5%) and placebo patch was compared by combining data for patients receiving the respective treatment regardless of the randomized study sequence.
Overall Treatment Difference in the LSMeans of the Average of the Last Two Daily Pain Relief Scale (PRS) Scores
The Pain Relief Scale (PRS) is a 9-point categorical rating scale to assess pain relief during the 24-hours since the last assessment; 0= completely worse and 8= complete pain relief. Patients completed this assessment each day during the run-in period and each day during the double-blind treatment phase in their e-diary.
Overall Treatment Difference of the LSMeans of the Pain Quality Assessment Scale (PQAS) Scores
The PQAS measures individual pain qualities and the impact of treatment on those qualities. Items 1-19 are each rated on an 11-point scale ranging from 0 (lowest score - no pain of that type) to 10 (highest score - the highest level of that type of pain). Average surface pain = average of PQAS items: cold, sensitive, itchy, numb, and tingling. Average deep pain = average of PQAS items: dull, cramping, throbbing, aching, and heavy. Average paroxymal pain = average of PQAS items: sharp, shooting, electric, and radiating.
Patient Global Impression of Change From Baseline in Osteoarthritis (OA) Pain
Patients rated their overall impression of change from Baseline to the end of each period during the double-blind treatment period, including premature discontinuation. Change was rated using a categorical scale indicating: "very much worse" (0); "much worse" (1); "minimally worse" (2); "no change" (3); "minimally improved" (4); "much improved" (5); and "very much improved" (6).
Investigator Global Impression of Change From Baseline in Osteoarthritis (OA) Pain
Investigators rated their overall impression of change from Baseline to the end of each period during the double-blind treatment period, including premature discontinuation. Change was rated using a categorical scale ranging from "very much worse" to "very much improved." A similar questionnaire was completed by the Investigator.
Patient Global Assessment of Treatment Satisfaction
At the end of each period, patients rated their overall satisfaction with study treatment using a 5-point categorical scale indicating: 0 - very dissatisfied; 1 - dissatisfied; 2 - no preference; 3 - satisfied; and 4 - very satisfied.
Investigator Global Assessment of Treatment Satisfaction
At the end of each period, investigators rated their overall satisfaction with study treatment using a 5-point categorical scale ranging from 0 (very dissatisfied) to 4 (very satisfied).

Other Pre-specified Outcome Measures:
Title
Overall Treatment Difference in LSMeans of Beck Depression Inventory Second Edition (BDI-II) Total Score
Description
The BDI-II is a 21-item self-report instrument intended to assess the existence and severity of symptoms of depression. Patients were to consider each item as it related to the way they felt for the previous 2 weeks. Each of the 21 items corresponding to a symptom of depression was summed to give a single score for the BDI-II, with a 4-point scale for each item ranging from 0-3. A total score of 0-13 is minimal, 14-19 is mild, 20-28 is moderate, and 29-63 is severe. Values were based on measurements taken at Screening, at Baseline (Visit 3), and at the end of each period.
Time Frame
Baseline and end of treatment period (up to 4 weeks)
Title

Description
The BDI-II is a 21-item self-report instrument intended to assess the existence and severity of symptoms of depression. Patients were to consider each item as it related to the way they felt for the previous 2 weeks. Each of the 21 items corresponding to a symptom of depression was summed to give a single score for the BDI-II, with a 4-point scale for each item ranging from 0-3. A total score of 0-13 is minimal, 14-19 is mild, 20-28 is moderate, and 29-63 is severe. Values were based on measurements taken at Screening, at Baseline (Visit 3), and at the end of each period.
