Section to complete information about primary and secondary outcomes including. It includes the metric or method of measurement used and, the time point for every outcome.
Primary outcome(s):
ACR clinical response (ACR20, ACR50 or ACR70. ACR20 decrease at least 20% in the number of painful joints and in the number of inflamed joints, and a 20% improvement in 3 of 5 following parameters: 1-Assessment of pain by the patient; 2-Overall evaluation of the patient's disease activity; 3-Overall assessment of disease activity by the physician; 4-Evaluation of the patient's physical function, through a self-assessment instrument; 5-Determination of acute phase reactants (C-reactive protein, erythrocyte sedimentation). ACR50 decrease at least 50% in the number of painful joints and in the number of inflamed joints, and a 50% improvement in 3 of 5 parameters. ACR70 decrease at least 70% in the number of painful joints and in the number of inflamed joints, and a 70% improvement in 3 of 5 parameters). Measurement time: at baseline, Weeks 1, 2, 3, 4 and, Months 2, 3, 4, 5, 6 and 9.
EULAR response (Assessment of clinical activity by DAS28. DAS28 <2.6 Referral; DAS28> 2.6 and = 3.2; Light disease activity; DAS28> 3.2 e = 5.2 Moderate disease activity; DAS28> 5.2 Severe disease activity). Measurement time: at baseline, Weeks 1, 2, 3, 4 and, Months 2, 3, 4, 5, 6 and 9.
Key secondary outcomes:
Clinical Adverse Events-AE (Ocurrence of AE (Yes, No), Description of AE (event name), -AE intensity (mild, moderate, severe)). Measurement time: at baseline, in the first four weeks, and in the months 2, 3, 4, 5, 6 and 9
Laboratory test (Numerical values of hemochemical tests: hemoglobin, hematocrit, leukogram with differential, velocity of globular sedimentation and platelet count). Measurement time: at the beginning, in the first four weeks, and in the months 2, 3, 4, 5, 6 and 9.
Immunological response:
Quantification of inflammatory cytokine levels (IL-17, IFNγ and TNFα). Measurement time: at baseline, months 6 and 9.
Determination of C-reactive protein (values of test). Measurement time: at baseline, months 6 and 9.
Citrullinated antibodies (values obtained by ELISA in patient sera). Measurement time: at baseline, months 6 and 9.
Imaging response:
Evaluation of the imaging changes (edema, erosion, synovitis) in the most affected hand of the patients through magnetic resonance imaging. Measurement time: at the beginning and in the months 6 and 9.
Quality of life (Questionnaire SF36). Measurement time: at baseline, Weeks 1, 2, 3 and 4, Months 2, 3, 4, 5, 6 and 9.
Clinical response according to SDAI (Simplified Disease Activity Index. High activity> 26, Moderate activity> 11.1 and <26, Low activity> 3.3 and <11, Remission <3.3). Measurement time: Weeks 24 and 36.
Clinical response according to SDAI (Clinical Disease Activity Index. High Activity> 22, Moderate Activity> 10.0-22, Low Activity> 2.8 -10, Referral 2.8). Measurement time: Weeks 24 and 36.
