Primary | Part A: Average Difference Between Baseline and Post Dose Evoked (by Treadmill Walking) Lower-Extremity Pain Intensity Scores (AELEPID) Over the 6 Hours After Dosing | Approximately 1 hour before baseline and again approximately 45 minutes before the 2-, 4-, and 6-hour time points, participants rested for 45 minutes, then they started the treadmill walk at 15 minutes before baseline and at the 2-, 4-, and 6-hour time points. After the treadmill walk, participants were asked to rate their lower extremity pain on an 11 point Numeric Pain Rating Scale (NPRS), with 0 indicating No Pain and 10 indicating Worst Possible Pain. The average difference between baseline and 6 hours post dose evoked lower-extremity pain intensity scores (AELEPID-6) is presented for each treatment group. Difference = predose (baseline) NPRS score - NPRS score 6 hours post dose. Least square (LS) means and standard errors (SE) were calculated from an analysis-of-covariance (ANCOVA) model with fixed effects for sequence, treatment, period, predose evoked lower extremity pain intensity as a covariate, and a random effect for participant nested within sequence. |
Baseline through 6 hours post dose | No |
Primary | Part B: The Mean of Daily Average "Now" Lower Extremity Pain Intensity (LEPI) Score During the 2-Week Period | Participants assessed their "Now" LEPI 3 times each day (morning, midday, and evening at approximately 10 AM, 2 PM, and 8 PM) and before taking any rescue medication. At each time point, participants were asked to rate their lower extremity pain on an 11-point Numeric Pain Rating Scale (NPRS), with 0 indicating No Pain and 10 indicating Worst Possible Pain. If a scheduled pain assessment was taken within 4 hours of rescue medication, the observed pain score was replaced by the pain score obtained right before the rescue medication was taken. LS means and SE were calculated from an analysis-of-covariance model with effect for treatment and baseline "Now" LEPI (before dosing for Treatment Period 1 of Part A) as a covariate. Participants with no postbaseline assessments were excluded from the baseline summary. |
Baseline through 2 Weeks | No |
Secondary | Part A: Pain Intensity Score (NPRS Score) for Overall Pain, for Lower Extremity Pain, and for Evoked (by Treadmill Walking) Lower Extremity Pain | Overall Pain Intensity (OPI), "Now" Lower Extremity Pain Intensity (LEPI), and Evoked Lower Extremity Pain Intensity (ELEPI) were assessed using the 11-point Numeric Pain Rating Scale (NPRS), with 0 indicating No Pain and 10 indicating Worst Possible Pain. OPI was assessed at 15 minutes before dosing for baseline and at 6 and 12 hours (hr) after dosing. At 15 minutes before dosing, during Period 1 only, participants were also asked to assess their average LEPI over the last 24 hours as a baseline measurement. "Now" LEPI was assessed at 15 minutes before dosing for baseline and at the 1-, 2-, 3-, 4-, 5-, 6-, and 12-hour time points. Approximately 1 hour before dosing and approximately 45 minutes before the 2-, 4-, and 6-hour time points, the participant rested for 45 minutes, then (after the "Now" LEPI assessment) he or she started a treadmill walk at 15 minutes before dosing for baseline and at the 2-, 4-, and 6-hour time points, and then assessed ELEPI. | Baseline up to 12 hours post dose | No |
Secondary | Part B: Mean Daily LEPI Scores for Weeks 1 and 2 | Participants assessed their "Now" LEPI 3 times each day (morning, midday, and evening at approximately 10 AM, 2 PM, and 8 PM) and before taking any rescue medication. At each time point, participants were asked to rate their lower extremity pain on an 11 point Numeric Pain Rating Scale (NPRS), with 0 indicating No Pain and 10 indicating Worst Possible Pain. If a scheduled pain assessment was taken within 4 hours of rescue medication, the observed pain score was replaced by the pain score obtained right before the rescue medication was taken. | Baseline through Week 1 and Week 1 through Week 2 | No |
Secondary | Part A: Pain Intensity Difference Between Baseline and the Value at Each Scheduled Time Point for Overall Pain | Overall Pain Intensity (OPI) was assessed by the participant using the 11-point Numeric Pain Rating Scale (NPRS), with 0 indicating No Pain and 10 indicating Worst Possible Pain. OPI was assessed at 15 minutes before dosing for baseline and at 6 and 12 hours after dosing. Difference = predose (baseline) OPI score - OPI score 6 and 12 hours post dose. | Baseline, 6 and 12 hours post dose | No |
Secondary | Part A: Average Difference Between Baseline and Postdose Evoked Lower Extremity Pain Over the 4 Hours After Dosing | Evoked Lower Extremity Pain Intensity (ELEPI) was assessed using the 11-point Numeric Pain Rating Scale (NPRS), with 0 indicating No Pain and 10 indicating Worst Possible Pain. Approximately 1 hour before dosing and approximately 45 minutes before the 2-, 4-, and 6-hour time points, the participant rested for 45 minutes, then he or she started a treadmill walk at 15 minutes before dosing for baseline and at the 2-, 4-, and 6-hour time points, and then assessed ELEPI. Difference = predose (baseline) ELEPI score - ELEPI score 4 hours post dose. | Baseline, 4 hours post dose | No |
Secondary | Part A: Mean Peak Difference in ELEPI According to the NPRS Scale | Evoked Lower Extremity Pain Intensity (ELEPI) was assessed using the 11-point NPRS. Participants were asked to rate their lower extremity pain on an 11 point NPRS, with 0 indicating No Pain and 10 indicating Worst Possible Pain. If a scheduled pain assessment was taken within 4 hours of rescue medication, the observed pain score was replaced by the pain score obtained right before the rescue medication was taken. Approximately 1 hour before dosing and approximately 45 minutes before the 2-, 4-, and 6-hour time points, the participant rested for 45 minutes, then he or she started a treadmill walk at 15 minutes before dosing for baseline and at the 2-, 4-, and 6-hour time points, and then assessed ELEPI. Peak ELEPID was defined as the maximum of ELEPIDs recorded at 2, 4, and 6 hours post dose. Difference = predose (baseline) NPRS score - peak NPRS score up to 6 hours post dose. | Baseline, Up to 6 hours post dose | No |
Secondary | Part A: Percentage of Participants in Each Treatment Group Achieving a 25%, 50%, or 75% Reduction From Baseline in Evoked Lower Extremity Pain Intensity Scores | Percentage was measured by identifying the number of participants who achieved the desired percentage Reduction From Baseline in ELEPI Score at either 2, 4, and 6 hours post dose and was divided the by the number of total participants in the given group and then multiplied by 100 to equate to a percentage. | Up to 2, 4, and 6 hours post dosing | No |
Secondary | Part B: Participants' Global Evaluation of Study Medication | For Part B, each participant's global evaluation (overall impression) of study medication was obtained at each weekly visit. Scores were recorded on the Case Report Form (CRF) on a 5 point scale ranging from "excellent" to "poor". Participant counts per score were reported at Week 1 (Day 7) and Week 2 (Day 14). | Up to Week 1 and Week 2 | No |
Secondary | Part B: Mean Daily Average LEPI Scores Over the Last 24 Hours at Week 1 and Week 2 | Each day during Part B, participants rated their Lower Extremity Pain Intensity over the last 24 hours on an 11-point NPRS, with 0 indicating No Pain and 10 indicating Worst Possible Pain | Week 1 and Week 2 | No |
Secondary | Part B: Mean Daily Average Overall Pain Intensity Scores Over Week 1, Over Week 2, and Over a 2-Week Period | During Part B, participants returned to the clinic for 2 additional visits at approximately weekly intervals for assessments of Overall Pain Index (OPI). Participants rated their OPI on an 11-point Numeric Pain Rating Scale (NPRS) with 0 indicating No Pain and 10 indicating Worst possible pain | Baseline through Week 1, Week 1 through Week 2, and Baseline through Week 2 | No |
Secondary | Part B: Percentage of Participants Using Rescue Medication | The percentage of participants who took at least 1 dose of rescue medication during 2-week treatment period of Part B is presented. | Baseline through Week 2 | No |
Secondary | Part A: Participant's Global Evaluation of Study Medication | For each treatment period during Part A, each participant's global evaluation (overall impression) of study medication was obtained 6 hours after dosing. Scores were recorded on the Case Report Form (CRF) on a 5 point scale ranging from "excellent" to "poor". Participant counts per score were reported once in Part A. | 6 hours post dose during Treatment Periods 1, 2, and 3 of Part A | No |
