NCT04688398

Brief Summary

This project proposes to conduct the first fully controlled and randomized clinical study demonstrating the impact of DPA-rich sea bass oil on the reduction of symptoms related to rheumatoid arthritis. This unique approach will allow to clinically evaluate the benefits of sea bass oil on the relief of rheumatoid arthritis-related pain in a population suffering from inflammatory arthritis.

Outcome Measures

Primary Outcomes (1)

  • Efficacy of DPA-rich seal oil in improving the clinical signs and symptoms associated with rheumatoid arthritis

    Change in the RADAI (Rheumatoid Arthritis Disease Activity Index) score post intervention is measured with a self-administrated questionnaire of 5 questions. Total score can vary from 0 to 10. Higher the score, higher the signs and symptoms.

    One year after the beginning of the study

Secondary Outcomes (8)

  • Degree of disease activity through the 66/68-swollen and tender joint count (SJC66/TJC68)

    One year after the beginning of the study

  • Overall blood biomarkers of inflammation (cytokines)

    One year after the beginning of the study

  • Overall inflammation

    One year after the beginning of the study

  • Patient's overall health

    One year after the beginning of the study

  • Patient's quality of life measured with MOS 36-item short-form health survey (SF36)

    One year after the beginning of the study

  • +3 more secondary outcomes
