  Purpose

The main objective of the study is to evaluate the effectiveness, tolerability, and safety of tapentadol hydrochloride prolonged release in participants suffering from severe chronic pain due to osteoarthritis of the knee who are taking either WHO Step I or Step II analgesics or no regular analgesics. This is a clinical effectiveness trial designed to establish a link between anticipated clinical outcomes and the clinical practice by means of selected measures of clinical and subject-reported outcome.

The trial will compare the effectiveness of previous analgesic treatment (either WHO Step I or Step II analgesics or no regular analgesics) with that of tapentadol hydrochloride prolonged release (PR) treatment during defined periods of evaluation.

Primary Outcome Measures:
  • The Primary Endpoint is Defined as the Change From Week -1 of the Average Pain Intensity Score on an 11-point NRS-3 at Week 6. [ Time Frame: Baseline to end of week 6 ] [ Designated as safety issue: No ]
    For this pain assessment, the participant was to indicate the level of average pain experienced over the previous 3 days on an 11-point Numerical Rating Scale(NRS) where a score of 0 indicated "no pain" and a score of 10 indicated "pain as bad as you can imagine". The value indicates the change from the baseline value on the 0 to 10 scale. A Negative value indicates a reduction in pain intensity from the baseline average pain intensity.


Secondary Outcome Measures:
  • Average Pain Intensity Before the Start of Tapentadol Treatment [ Time Frame: Baseline ] [ Designated as safety issue: No ]
    For this pain assessment, the participant was to indicate the level of average pain experienced over the previous 3 days on an 11-point Numerical Rating Scale (NRS)where a score of 0 indicated "no pain" and a score of 10 indicated "pain as bad as you can imagine".

  • Change in Average Pain Intensity After 6 Weeks of Tapentadol PR Treatment [ Time Frame: Baseline; End of Week 6 (6 Weeks) ] [ Designated as safety issue: No ]
    For this pain assessment, the participant was to indicate the level of average pain experienced over the previous 3 days on an 11-point Numerical Rating Scale(NRS) where a score of 0 indicated "no pain" and a score of 10 indicated "pain as bad as you can imagine". The value indicates the change from the baseline value on the 0 to 10 scale. A Negative value indicates a reduction in pain intensity from the baseline average pain intensity.

  • Change in Average Pain Intensity After 12 Weeks of Tapentadol PR Treatment [ Time Frame: Baseline; End of Week 12 (12 Weeks) ] [ Designated as safety issue: No ]
    For this pain assessment, the participant was to indicate the level of average pain experienced over the previous 3 days on an 11-point Numerical Rating Scale(NRS) where a score of 0 indicated "no pain" and a score of 10 indicated "pain as bad as you can imagine". The value indicates the change from the baseline value on the 0 to 10 scale. A Negative value indicates a reduction in pain intensity from the baseline average pain intensity.

  • EuroQol-5 (EQ-5D) Health Status Index Outcome Over Time [ Time Frame: Baseline; End of Week 6 (6 Weeks) ] [ Designated as safety issue: No ]
    The participant scored the EuroQol-5. This is a five dimensional health state classification. Each dimension is assessed on a 3-point ordinal scale (1=no problems, 2=some problems, 3=extreme problems). The responses to the five EQ-5D dimensions were scored using a utility-weighted algorithm to derive an EQ-5D health status index score between 0 to 1, with 1.00 indicating "full health" and 0 representing dead. The positive values indicate that during the study the health status improved.

    Western Ontario McMaster Questionnaire (WOMAC) Global Score: WOMAC is measured with a Likert ordinal scale (the participant gives one of 5 possible answers) A higher score indicate that a symptom is bothersome or disabling. The WOMAC is a self-administered questionnaire and has 24 questions: Pain, Stiffness and Physical Function. The possible scores range from 0-20 for pain, 0-8 for stiffness, 0-68 for physical function and these are then summed 0-96 for the global score. A lower score indicates a lower level of symptoms and or disability.
