E.2 Objective of the trial |
E.2.1 | Main objective of the trial |
The primary objective is to compare the safety and efficacy of multiple doses of ABT-494 versus placebo in moderately to severely active RA subjects on stable background MTX therapy with inadequate response or intolerance to anti-TNF biologic therapy. |
El objetivo principal es comparar la seguridad y la eficacia de varias dosis de ABT-494 en comparación con placebo en pacientes con AR activa moderada o grave que reciben un tratamiento de base estable con MTX que presentaron una respuesta inadecuada o intolerancia a un tratamiento biológico anti-TNF. |

2. Diagnosed with RA based on the 2010 American College of Rheumatology (ACR)/European League against Rheumatism (EULAR) criteria for greater than or equal to 3 months.
3. Subjects must have been receiving oral or parenteral MTX therapy greater than or equal to 3 months and on a stable prescription of 7.5 to 25 mg/week for at least 4 weeks prior to initiating the study drug.

5. Have active RA as defined by the following minimum disease activity criteria: greater than or equal to 6 swollen joints (based on 66 joint counts) at Screening and Baseline Visits; greater than or equal to 6 tender joints (based on 68 joint counts) at Screening and Baseline Visits; hs-CRP greater than 7 mg/L. |

1. Refieren antecedentes de falta de respuesta clínica al tratamiento inicial con un agente biológico anti-TNF.
2. Reciben un tratamiento biológico previo distinto de un anti-TNF (p. ej., tocilizumab, rituximab, anakinra o abatacept).
3. Han recibido anteriormente un inhibidor de la cinasa JAK (p. ej., tofacitinib o baricitinib).
4. Recibe un fármaco en investigación de naturaleza biológica o química en un período mínimo de 30 días o 5 semividas del fármaco (el período más largo de ellos) antes de iniciar el fármaco del estudio.
5. Necesitan actualmente o se espera que necesiten otros medicamentos inmunodepresores, excepto MTX. Reciben una dosis oral de prednisona mayor de 10 mg/día o de un corticoesteroide equivalente.
