Outcome Measures
Primary Outcome Measures
- Change of the Subject's Target OA Knee Compared to the Baseline as Assessed by WOMAC [week 12]
The Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC) has been used to assess subjects with OA of the hip or knee and consists of 24 questions in subscales measuring 3 concepts: pain, stiffness, and physical function. These questions measure the amount of pain, degree of difficulty in completing various day-to-day activities, and stiffness experienced in the hip or knee. Usually subject self-administered. A single question has 100 grades, where 0 = very good and 100 = very much worse. VAS (visual analog scale) scale is used for score record. Data for the exploratory efficacy endpoints will be summarized using descriptive statistics. Safety analyses will be conducted on the SAS. Safety parameters will be listed and summarized using standard descriptive statistics.
Secondary Outcome Measures
- Incidence of Treatment-Emergent Adverse Events of X0002 Spray [week 1 to week 14]
A sensitivity analysis will also be conducted on the Primary Efficacy Endpoint using an ANCOVA with treatment as a fixed class effect and WOMAC baseline pain subscale score as covariates, but the comparisons of interest will be the difference between the active and placebo subjects within each treatment group. The Secondary Efficacy Endpoints, change from Baseline in the WOMAC subscale scores for pain, stiffness, and functional ability, and overall WOMAC score, will be by analyzed using the same methods as the for the Primary Efficacy Endpoint. Safety analyses will be conducted on the SAS. Safety parameters will be listed and summarized using standard descriptive statistics, as appropriate. No formal statistical analyses are planned.
- Relief of Knee Pain in Subjects With Osteoarthritis (OA) of the Knee as Evaluated by WOMAC Subscale [week 2，4，8]
The WOMAC pain subscale has 5 questions. Usually subject self-administered. A single question has 100 grades, where 0 = no pain and 100 = pain as bad as can be. The Primary Efficacy Endpoint is change from Baseline in the WOMAC (VAS) pain subscale score for the target knee at week 2, 4, 8, and will be analyzed by an analysis of covariance (ANCOVA). Treatment will be included as a fixed class effect and WOMAC Baseline pain subscale score as covariates.
- Relief of Joint Stiffness After Using X0002 Spray as Evaluated by WOMAC Subscale [week 2，4，8, 12]
The WOMAC stiffness subscale has 2 questions. Usually subject self-administered. A single question has 100 grades, where 0 = no stiffness and 100 = stiffness as bad as can be. A sensitivity analysis will also be conducted on the Primary Efficacy Endpoint using an ANCOVA with treatment as a fixed class effect and WOMAC baseline stiffness subscale score as covariates, but the comparisons of interest will be the difference between the active and placebo subjects within each treatment group. The Secondary Efficacy Endpoints, change from Baseline in the WOMAC subscale scores for stiffness at 2, 4, 8, and 12 weeks of treatment, will be by analyzed using the same methods as the for the Primary Efficacy Endpoint. Safety analyses will be conducted on the SAS. Safety parameters will be listed and summarized using standard descriptive statistics, as appropriate. No formal statistical analyses are planned.
- Difficulty Performing Daily Activities of OA Subjects as Assessed by WOMAC subscale [week 2，4，8, 12]
The WOMAC physical function subscale has 17 questions. Usually subject self-administered. A single question has 100 grades, where 0 = very good and 100 = very much worse. A sensitivity analysis will also be conducted on the Primary Efficacy Endpoint using an ANCOVA with treatment as a fixed class effect and WOMAC baseline pain subscale score as covariates, but the comparisons of interest will be the difference between the active and placebo subjects within each treatment group. The Secondary Efficacy Endpoints, change from Baseline in the WOMAC subscale scores for pain, stiffness, and functional ability, and overall WOMAC score at 2, 8, and 12 weeks of treatment, will be by analyzed using the same methods as the for the Primary Efficacy Endpoint. Safety analyses will be conducted on the SAS. Safety parameters will be listed and summarized using standard descriptive statistics, as appropriate. No formal statistical analyses are planned.
- Total Score of WOMAC Subscale as Estimated by Visual Analog Scale [week 2，4，8, 12]
The WOMAC subscale has 24 questions. Usually subject self-administered. A single question has 100 grades, where 0 = very good and 100 = very much worse. The total score is 2400, the lower, the better; higher score means worse condition. Data for the exploratory efficacy endpoints will be summarized using descriptive statistics. Safety analyses will be conducted on the SAS. Safety parameters will be listed and summarized using standard descriptive statistics, as appropriate. No formal statistical analyses are planned.
- Subject's Global Assessment of Disease Status of the Target Knee as Estimated by Visual Analog Scale at 2, 4, 8 and 12 Weeks of Treatment [week 2，4，8, 12]
The subject's overall evaluation of the condition is the relevant questionnaire (0-100mm visual analogue scale), which needs to be completed at the time points listed in the study flow chart. On the scale line of 100mm VAS, mark the left side to indicate "very good" and mark the right side means "Very bad." Data for the exploratory efficacy endpoints will be summarized using descriptive statistics. Safety analyses will be conducted on the SAS. Safety parameters will be listed and summarized using standard descriptive statistics, as appropriate. No formal statistical analyses are planned.
- Subject's Global Assessment of Response to Therapy of the Target Knee as Estimated by Visual Analog Scale at 2, 4, 8 and 12 Weeks of Treatment [week 2，4，8, 12]
The subjects' overall evaluation of treatment response is that they fill in the relevant questionnaire VAS (visual analog scale) (VAS, 0~4 points), which should be completed in the time points listed in the study flow chart. 0 = very poor; 4 = very good. Data for the exploratory efficacy endpoints will be summarized using descriptive statistics. Safety analyses will be conducted on the SAS. Safety parameters will be listed and summarized using standard descriptive statistics, as appropriate. No formal statistical analyses are planned.
- Amount of Rescue Medication (Acetaminophen) Consumed Per Day for Target Knee Pain [week 2，4，8, 12]
Data for the exploratory efficacy endpoints will be summarized using descriptive statistics. Safety analyses will be conducted on the SAS. Safety parameters will be listed and summarized using standard descriptive statistics, as appropriate. No formal statistical analyses are planned.
- Pharmacokinetic parameters(Maximum Plasma Concentration [Cmax]) of X0002 [1 h pre-dose, 1±0.5 h post-dose, 3±0.5 h post-dose, 5±0.5 h post-dose at week 8; 1 h pre-dose, 2±0.5 h post-dose, 4±0.5 h post-dose, 6±0.5 h post-dose at week 12]

Data for the exploratory efficacy endpoints will be summarized using descriptive statistics. Safety analyses will be conducted on the SAS. Safety parameters will be listed and summarized using standard descriptive statistics, as appropriate. No formal statistical analyses are planned.
- Change in the WOMAC Subscale Scores for Pain, Stiffness and Functional Ability of Target Knee [week 14]
The Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC) has been used to assess subjects with OA of the hip or knee and consists of 24 questions in subscales measuring 3 concepts: pain, stiffness, and physical function. These questions measure the amount of pain, degree of difficulty in completing various day-to-day activities, and stiffness experienced in the hip or knee. Usually subject self-administered. A single question has 100 grades, where 0 = very good and 100 = very much worse. Change in the WOMAC subscale scores for pain, stiffness, and functional ability at week 14 of treatment, will be by analyzed using the same methods as the for the Primary Efficacy Endpoint.
