E.2 Objective of the trial |
E.2.1 | Main objective of the trial |
The aim of this study (RABEX) is to investigative the physiological effects of the cytokines IL-6 and TNF on the adaptive changes to exercise in patients with rheumatoid arthritis.
We will compare rheumatoid arthritis patients in treatment with either IL-6 or TNF blockage on exercise-induced cardiac adaptations as well as metabolic adaptations including oral glucose tolerance test (OGTT) and changes in adipose tissue mass.

E.5 End points |
E.5.1 | Primary end point(s) |
To compare the physiological adaptations to exercise in reumatoid athritis patients in either IL-6 or TNF blockage. The following parameters will be measured:
Primary Change in left ventricular mass (MRI).
|
|
E.5.1.1 | Timepoint(s) of evaluation of this end point |
12 weeks (end of exercise intervention or control group (no exercise intervention)). |
|
E.5.2 | Secondary end point(s) |
To compare the physiological adaptations to exercise in reumatoid athritis patients in either IL-6 or TNF blockage. The following parameters will be measured:
Secondary Visceral adipose tissue mass (MRI). Stroke volume, left ventricular and atrial end-diastolic volume, LVEF, GLS, E/A, E/e’ (MRI and echocardiography). Functional vascular parameters: aortic and pulmonary distensibility and pulse wave velocity (MRI). Subcutaneous, visceral and epicardial adipose tissue, intramyocardial triglyceride content (MRI and MR spectroscopy). Cardiorespiratory measurements (VO2 max). Body composition (DXA). Lung function (forced expired volume in 1 second, forced vital capacity, total lung capacity, residual volume, and diffusing capacity). Blood samples analyzed for markers related to exercise, metabolism, inflammation and cardiovascular function. RA disease specific outcomes. |

Definition of the end of the trial and justification where it is not the last
visit of the last subject undergoing the trial
|
Inclusion period will end 26 months after the first subject has been recruited or if at least 16 subjects in each group have been deemed fully compliant to intervention or control (as described in the protocol) and further inclusion rate is below 2 patients per month. 16 subjects in each group, will meet the recommended power of 0.8 and alpha-level of 0.05 for the primary endpoint and this deadline is within the scope of the PhD study. |
