| List | Outcome | Time frame | Description |
|---|---|---|---|
| Primary | Pain on the Average, Mean Change From Baseline Days 21-84 (Last Observation Carried Forward [LOCF]) | On baseline day 1 and days 21, 30, 45, 60, 75, and 84, and, if applicable, at early termination. | Subjects were asked, "Please rate your pain by circling the one number (0-10) that best describes your pain on the average since your last visit." 0 = no pain and 10 = pain as bad as you can imagine it. |
| Primary | Pain Right Now, Mean Change From Baseline, Days 21-84 (LOCF) | Assessed at baseline day 1 and days 21, 30, 45, 60, 75, and 84, and, if applicable, at early termination. | Subjects were asked, "Please rate your pain by circling the one number (0-10) that tells how much pain you have right now." Subjects rated their answers on a 0-10 ordinal scale from 0 = "No pain" to 10 = "Pain as bad as you can imagine it." Pain right now is presented as the LSmean \[change from baseline\] (SE). |
| Secondary | "Physical Functioning" Scale of the Medical Outcomes Survey (MOS) 36 Item Short-Form Health Survey (SF-36): Mean Percent ± Standard Error of the Mean (SEM) at Day 84 (LOCF) | Day 84, or, if applicable, at early termination | The Medical Outcomes Survey (MOS) Short-Form-36 Health Survey (SF-36) assesses 8 categories of functionality through 36 individual questions. "Physical Functioning" is 1 of the 8 categories. Its transformed score, scaled from 0% to 100%, is used. A higher score represents a better subject condition. The survey was completed by the subject at the clinic. The mean scores were analyzed. |
| Secondary | "Physical Role" Scale (MOS SF-36): Mean Percent ± SEM at Day 84(LOCF) | Day 84 | The Medical Outcomes Survey Short-Form-36 health survey assesses 8 categories of functionality through 36 individual questions. "Physical Role" is 1 of the 8 categories. Its transformed score, scaled from 0% to 100%, is used. A higher score represents a better subject condition. The survey was completed by the subject at the clinic. The mean scores were analyzed. |
| Secondary | "Bodily Pain" (MOS SF-36): Mean Percent at Day 84 (LOCF) | Day 84 | The MOS Short-Form Health Survey assesses 8 categories of functionality through 36 individual questions. "Bodily Pain" is 1 of the 8 categories. Its transformed score, scaled from 0% to 100%, is used. A higher score represents a better subject condition. The survey was completed by the subject at the clinic. The mean scores were analyzed. |
| Secondary | "General Health" (MOS SF-36): Mean Percent ± SEM at Day 84 (LOCF) | Day 84 | The MOS Short-Form Health Survey assesses 8 categories of functionality through 36 individual questions. "General Health" is 1 of the 8 categories. Its transformed score, scaled from 0% to 100%, is used. A higher score represents a better subject condition. The survey was completed by the subject at clinic. The mean scores were analyzed. |
| Secondary | "Vitality" (MOS SF-36): Mean Percent ± SEM at Day 84 (LOCF) | Day 84 | The MOS Short-Form Health Survey assesses 8 categories of functionality through 36 individual questions. "Vitality" is 1 of the 8 categories. Its transformed score, scaled from 0% to 100%, is used. A higher score represents a better subject condition. The survey was completed by the subject at the clinic. The mean scores were analyzed. |
| Secondary | "Social Functioning" (MOS SF-36): Mean Percent ± SEM at Day 84 (LOCF) | Day 84 | The MOS Short-Form Health Survey assesses 8 categories of functionality through 36 individual questions. "Social Functioning" is 1 of the 8 categories. Its transformed score, scaled from 0% to 100%, is used. A higher score represents a better subject condition. The survey was completed by the subject at the clinic. |
| Secondary | "Emotional Role" (MOS SF-36): Mean Percent ± SEM at Day 84 (LOCF) | Day 84 | The MOS Short-Form Health Survey assesses 8 categories of functionality through 36 individual questions. "Emotional Role" is 1 of the 8 categories. Its transformed score, scaled from 0% to 100%, is used. A higher score represents a better subject condition. The survey was completed by the subject at the clinic. |
| Secondary | "Mental Health" (MOS SF-36):Mean Percent ± SEM at Day 84 (LOCF) | Day 84 | The MOS Short-Form Health Survey assesses 8 categories of functionality through 36 individual questions. "Mental Health" is 1 of the 8 categories. Its transformed score, scaled from 0% to 100%, is used. A higher score represents a better subject condition. The survey was completed by the subject at the clinic. |
