Study summary

This study aims to evaluate the effectiveness and safety of a combined herbal supplement containing Boswellia serrata, Curcuma longa, and Vitis vinifera in adults with clinically diagnosed knee or hip osteoarthritis.

The primary objective is to determine whether the supplement improves osteoarthritis-related symptoms.

The supplement will be compared with a placebo.

Participants will:

  • take the supplement and placebo for 4 weeks each, one at a time;
  • complete validated questionnaires (6 times online)
  • perform three performance-based physical tests (6 times online)
  • provide a urine sample

What researchers measure

Primary outcomes

  1. Change in Western Ontario and McMaster Universities Arthritis Index (WOMAC) score

    Western Ontario and McMaster Universities Arthritis Index, a validated, specialised instrument used to assess pain, stiffness, and physical function in people with osteoarthritis. Scores range from 0 to 96 (Likert version), with higher scores indicating worse pain (0-20), stiffness (0-8), and physical function (0-68).

    Time frame: Change from the start of the intervention to Week 4 of supplementation

  2. Change in Numeric Rating Scale (NRS) score

    Numeric Rating Scale. A specialised pain assessment tool, where patients rate their pain intensity on a scale from 0 to 10, where 0 indicates no pain and 10 indicates worst imaginable pain; higher scores indicate worse outcomes.

    Time frame: Change from the start of the intervention to Week 4 of supplementation

  3. Change in Intermittent and Constant Osteoarthritis Pain knee/hip (ICOAP) score

    ICOAP. A Measure of Intermittent and Constant Osteoarthritis Pain knee/hip To assess two distinct types of pain experienced by people with osteoarthritis-intermittent pain (comes and goes, 0 - 24) and constant pain (persistent, ongoing pain, 0 - 20). Scores range from 0 to 44, with higher scores indicating more severe osteoarthritis related pain.

    Time frame: Change from the start of the intervention to Week 4 of supplementation

  4. Change in EuroQol 5-Dimension 5-Level (EQ-5D-5L) score

    EuroQol 5-Dimension 5-Level questionnaire. A generic, widely used tool to measure health-related quality of life. It measures five dimensions: Mobility, Self-care, Usual activities, Pain/discomfort, Anxiety/depression. A score of 1 indicates no problems, while 5 indicates extreme problems in the respective dimension. In addition, the EQ Visual Analogue Scale (EQ-VAS) records the respondent's self-rated health on a vertical scale ranging from 0 to 100, where 0 represents the worst imaginable health state and 100 represents the best imaginable health state.

    Time frame: Change from the start of the intervention to Week 4 of supplementation

  5. Change in urinary C-terminal telopeptide of type II collagen (uCTX-II) levels

    uCTX-II (urinary C-terminal telopeptide of type II collagen) is a biochemical marker measured in urine that reflects type II collagen degradation, which occurs primarily in articular cartilage.

    Time frame: Change from the start of the intervention to Week 4 of supplementation

Secondary outcomes
