Outcomes

Primary Outcome Measures

Change From Baseline in Weekly Mean 24-hour Average Pain Severity (APS) Score From Electronic Diary at 5 Weeks
This scale measured 24-hour APS scores. Data were recorded daily (preferably at bedtime) on an 11-point Likert scale, an ordinal scale ranging from 0 (no pain) to 10 (worst possible pain). Least Squares (LS) Means were adjusted for baseline, investigator, treatment, visit, a treatment-by-visit interaction, and a baseline-by-visit interaction.

Secondary Outcome Measures

Change From Baseline in Weekly Mean Night Pain Severity Score From Electronic Diary at 5 Weeks
This scale measured night pain APS scores. Data were recorded daily on an 11-point Likert scale, an ordinal scale ranging from 0 (no pain) to 10 (worst possible pain). LS Means were adjusted for baseline, investigator, treatment, visit, a treatment-by-visit interaction, and a baseline-by-visit interaction.
Change From Baseline in Weekly Mean Worst Daily Pain Severity Score From Electronic Diary at 5 Weeks
This scale measured worst pain APS scores. Data were recorded daily (preferably at bedtime) on an 11-point Likert scale, an ordinal scale ranging from 0 (no pain) to 10 (worst possible pain). LS Means were adjusted for baseline, investigator, treatment, visit, a treatment-by-visit interaction, and a baseline-by-visit interaction.
Number of Participants With 30% Reduction in Weekly Mean 24-hour Average Pain Severity (APS) Score
This scale measured 24-hour APS scores. Data were recorded daily (preferably at bedtime) on an 11-point Likert scale, an ordinal scale ranging from 0 (no pain) to 10 (worst possible pain). The 11-point Likert scale was also used for assessment of night pain and worst pain each day, evaluated as weekly means.
Change From Baseline in Clinical Global Impression of Severity (CGI-S) Score at 5 Weeks
CGI-S measured severity of illness at the time of assessment compared with start of treatment. Scores ranged from 1 (normal, not at all ill) to 7 (among the most extremely ill patients). LS Means were adjusted for baseline, investigator, treatment, visit, a treatment-by-visit interaction, and a baseline-by-visit interaction.
Change From Baseline in Average Brief Pain Inventory - Interference (BPI-I) Subscale Score at 5 Weeks
Average BPI-I was a self-reported scale measuring degree of pain interference on function. Interference scores: 0 (does not interfere) to 10 (completely interferes) on each question assessed 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 non-missing scores of individual interference items. LS Means were adjusted for baseline, investigator, treatment, visit, a treatment-by-visit interaction, and a baseline-by-visit interaction.
Change From Baseline in Brief Pain Inventory - Severity (BPI-S) Subscale Score at 5 Weeks
BPI-S was a self-reported scale measuring severity of pain. Severity scores: 0 (no pain) to 10 (severe pain) on each question assessed worst pain, least pain, and average pain in past 24 hours, and current pain. LS Means were adjusted for baseline, investigator, treatment, visit, a treatment-by-visit interaction, and a baseline-by-visit interaction.
Patient Global Impression of Improvement (PGI-I) Score at 5 Weeks
PGI-I was a scale that measured the participant's perception of improvement at the time of assessment compared with the start of treatment. The score ranged from 1 (very much better) to 7 (very much worse). LS Means were adjusted for baseline, investigator, treatment, visit, a treatment-by-visit interaction, and a baseline-by-visit interaction.
Change From Baseline in Assessment of Sleep Questionnaire (ASQ) Total Score at 5 Weeks
ASQ consisted of 21 items (including a single item to assess overall sleep quality) and 3 subscales: Sleep Onset and Maintenance (items 1-3, 5-6, 9, 11); Sleep Experience (items 4, 7, 8, 10, 12); and Awakening Experience (items 13-20). Each item was scored on a 5-point Likert scale, ranging from 0 (no sleep at all) to 5 (a lot of sleep). Each subscale was calculated as the mean of the individual items comprising the subscale. A total ASQ score was calculated as the mean of the subscale scores; higher scores represented better sleep.
Change From Baseline in Total Western Ontario and MacMaster (WOMAC) Osteoarthritis Physical Function, Pain, and Stiffness Subscales at 5 Weeks
The Total WOMAC index (pain, stiffness, physical function subscales) was completed by the participant and had 24 questions. Each question was answered using a 5-point Likert scale (0 to 4). The Total score had a range from 0 (none) to 96 (extreme). LS Means were adjusted for baseline, investigator, treatment, visit, a treatment-by-visit interaction, and a baseline-by-visit interaction.
Change From Baseline in Short Form-36 (SF-36) Health Survey Bodily Pain Score at 5 Weeks
The SF-36 Health Status Survey was a generic, health-related scale assessing participants' quality of life on 8 domains: physical functioning, social functioning, bodily pain, vitality, mental health, role-physical, role-emotional and general health and 2 summary scores (mental component summary [MCS] and physical component summary [PCS]). MCS and PCS scores=0-100 (higher scores indicated better health status). Domain scores: general health=5-25; physical functioning=10-30; role-physical=4-8; role-emotional=3-6; social functioning=2-10; bodily pain=2-11; vitality=4-24; mental health=5-30.
Change From Baseline in European Quality of Life Scale - 5 Dimensions (EQ-5D) at 5 Weeks: United States Population Based Index Score
The EuroQoL Questionnaire - 5 Dimension (EQ-5D) was a generic, multidimensional, health-related, quality-of-life instrument. The profile allowed participants to rate their health state in 5 health domains: mobility, self-care, usual activities, pain/discomfort, and mood. A single score between 1 and 3 was generated for each domain. For each participant, the outcome rating on the 5 domains was mapped to a single index through an algorithm. The index ranged between 0 and 1, with the higher score indicating a better health state perceived by the participant.
Change From Baseline in Sheehan Disability Scale (SDS) Global Impairment Score at 5 Weeks
The SDS was completed by the participant and was used to assess the effect of the participant's symptoms on their work/social/family life. Total scores ranged from 0 to 30 with higher values indicating greater disruption in the participant's work/social/family life. LS Means were adjusted for baseline, investigator, treatment, visit, a treatment-by-visit interaction, and a baseline-by-visit interaction.
Number of Participants Who Discontinued Due to Treatment Emergent Adverse Events (TEAEs) During the Therapy Phase and 1-Week Washout Phase
Participant discontinuation in the study due to serious and other non-serious AEs was measured during both the therapy (double-blind) phase and 1-week washout (follow-up) phase. A listing of serious and other non-serious AEs is located in the Reported Adverse Event module.
Number of Participants With Serious Treatment Emergent Abnormal High or Low Laboratory Values
The number of participants by treatment group who had abnormal high or low laboratory values was summarized as serious adverse events (SAEs) from the "Investigations" system organ class during the treatment phase of the study. A listing of SAEs is located in the Reported Adverse Event module.
Change From Baseline in Vital Signs: Systolic Blood Pressure and Diastolic Blood Pressure at 5 Weeks
Participants' systolic blood pressure and diastolic blood pressure were measured in millimeters of mercury (mmHg). LS Means were adjusted for baseline, investigator, treatment, visit, a treatment-by-visit interaction, and a baseline-by-visit interaction.
Change From Baseline in Vital Signs: Pulse Rate at 5 Weeks
Pulse rate was measured in beats per minute (bpm). LS Means were adjusted for baseline, investigator, treatment, visit, a treatment-by-visit interaction, and a baseline-by-visit interaction.
Number of Participants With Electrocardiogram (ECG) Change in Heart Rate Using Bazett's (QTcB) and Fridericia's (QTcF) Formulas
The number of participants having QTcF and QTcB ECG change >450 milliseconds (msec) was summarized.
Number of Participants Reporting Blurry or Hazy Vision Using the Subjective Vision Inventory (SVI) Question 1 (Q1) at 5 Weeks
This scale first asked if the participant was experiencing hazy or blurry vision or if he/she had difficulty focusing. If the answer was yes, followup questions rated the degree to which the issue impaired his/her ability to do work or read.
Pharmacokinetic (PK) Parameter: Clearance of LY545694 (CLp) and Compound 645838 (CLm)
Clearance was the volume of plasma cleared of study drug LY545694 (CLp) and metabolite compound 645838 (CLm) per unit time. The original PK/pharmacodynamic (PD) relationship outcome measure analysis was not conducted; therefore, only PK data were reported.
Number of Participants With Neurological Treatment Emergent Adverse Events (AEs)
The total number of TEAEs (serious and non-serious) that first occurred or worsened during the treatment period) from the "Nervous system disorders" system organ class was summarized. A listing of serious and other non-serious AEs is located in the Reported Adverse Event module.
Time to Response
Time to response=first visit achieving a 30% reduction of weekly mean 24-hour APS score. Data were recorded daily (preferably at bedtime) on an 11-point Likert scale, an ordinal scale ranging from 0 (no pain) to 10 (worst possible pain). The number of days at which 30% of the participants at risk had at least 30% response was reported.
