E.2 Objective of the trial |
E.2.1 | Main objective of the trial |
Rheumatoid arthritis (RA) is a common condition affecting 1-2% of people worldwide. It is a condition that affects the immune system, in which the body attacks it's own joints and tissues. As a result of the inflammation caused, people with RA can experience inflammation, pain and fatigue. Over the last 2 decades, there have been major advances in the treatment of rheumatoid arthritis. The development of new drugs which can target the immune system to slow down or stop the damage to the body caused by RA have been developed. Some of the new treatments being used are antibody, or biologic treatments that are given as regular injections. We have a lot of understanding of how the drug treatments used e.g. adalimumab or abatacept, can control inflammation of the immune system. However, very little is known about how the biologic treatments influence different aspects of pain in RA. Our study will investigate how different biologic treatments, namely adalimumab or abatacept, influence pain |
|
E.2.2 | Secondary objectives of the trial |
In our research group we have developed new techniques to measure pain by examining patients and also performing blood tests. In addition to the pain questionnaires that we collect, we will be investigating whether the pain measurement techniques we use, called quantitative sensory testing (QST and blood testing can help identify distinct features of pain in people with RA. |

E.3 | Principal inclusion criteria |
• Active rheumatoid arthritis causing pain and functional impairment with DAS28 >5.1 • Has already received usual care for inflammatory arthritis including conventional DMARD therapy e.g. methotrexate, sulfasalazine, leflunomide, hydroxychloroquine on stable dose of csDMARD at least 4 weeks prior to study drug initiation • Willing to participate in the study over a 12 month period • Desirably to have positive antibodies to cyclic citrullinated peptide (ACPA/CCP) • Between 18 and 75 years of age
|

E.4 | Principal exclusion criteria |
• Pregnancy or pregnancy planned over next 12 months • Current or previous unsuccessful use of the biologics abatacept or adalimumab • Co-existing other autoimmune condition, e.g. systemic lupus erythematosus, Sjogren’s syndrome, connective tissue disease, fibromyalgia, osteoarthritis, gout • Recent surgery in the last 3 months or imminent surgery in the next 12 months • Unable to give informed consent • Previous history of cancer in the last 5 years • Previous history of multiple sclerosis • Uncontrolled heart failure, hypertension or diabetes mellitus • Known history of fibromyalgia or other chronic pain disorder • females of childbearing potential must have a negative pregnancy test within 7 days prior to treatment initiation) • Since the majority of subjects entering into the trial will be taking anchor medication in the form of methotrexate, it is advised that subjects do not conceive during the period of the trial and double contraception is advised at all times during the trial • Female subjects should not be breastfeeding
