Secondary
| Measure | Time frame |
|---|---|
| Secondary end point(s): Area under the VAS curve (AUC) during the first week until 8 p.m. on day 7. Pain intensity on McGill pain questionnaire (MPQ); daily activities; activity and mobility of the knee joint (Lysholm Gilquist-Score); WOMAC scale (before i.a. injec-tions and at the end of each week). Inflammatory parame-ters (cellular infiltrate, opioid receptors and peptides, IL-17, TNFa) in synovial biopsies and fluid (before and 7 days af-ter i.a. medication), supplementary analgesic consumption. Assessment of safety: Any systemic (e.g. nausea, sedation) and local side effects (infection, tissue injury) will be recorded. ;Timepoint(s) of evaluation of this end point: week 1, week 2, safety follow up week 3 | — |
Primary
| Measure | Time frame |
|---|---|
| Main Objective: To investigate pain and inflammatory parameters (cytokines, immune cells) in knee joint tissue of chronic arthritis pa-tients following intraarticular (i.a.) injections of morphine, a standard steroid or placebo. The primary hypothesis is that i.a. morphine results in sig-nificantly lower pain scores and supplemental analgesic consumption than placebo during the first week after injec-tion, an efficacy comparable to standard i.a. steroid (tri-amcinolone) medication. Primary efficacy endpoint: Reduction of pain intensity (on a 100mm VAS) at 8 a.m. on day 7 compared to baseline. ;Secondary Objective: Key secondary endpoint(s): Area under the VAS curve (AUC) during the first week until 8 p.m. on day 7. Pain intensity on McGill pain questionnaire (MPQ); daily activities; activity and mobility of the knee joint (Lysholm Gilquist-Score); WOMAC scale (before i.a. injec-tions and at the end of each week). Inflammatory parame-ters (cellular infiltrate, opioid receptors and peptides, IL-17, TNFa) in synovial biopsies and fluid (before and 7 days af-ter i.a. medication), supplementary analgesic consumption. Assessment of safety: Any systemic (e.g. nausea, sedation) and local side effects (infection, tissue injury) will be recorded. ;Primary end point(s): Primary efficacy endpoint: Reduction of pain intensity (on a 100mm VAS) at 8 a.m. on day 7 compared to baseline. ;Timepoint(s) of evaluation of this end point: week 1 | — |
