E.2 Objective of the trial |
E.2.1 | Main objective of the trial |
To demonstrate the superiority in efficacy of abatacept compared with adalimumab, both on background MTX, in achieving clinical response (ACR50) at Week 24, in early, seropositive (RF+ and ACPA+) RA patients with the SE HLA Class II risk alleles (ie, SE+). |
Demostrar la superioridad en eficacia de abatacept encomparación con adalimumab, en ambos casos, con MTX de base, para alcanzar respuesta clínica (ACR50) la semana24, en pacientes con AR precoz, seropositiva (FR+ y ACPA+) con los alelos de riesgo de clase II del HLA para el EC (es decir, EC+). |
|
E.2.2 | Secondary objectives of the trial |
To compare the efficacy of abatacept with adalimumab, both on background MTX in achieving: - clinical remission criteria (DAS28-CRP remission) at Week 24 in early, seropositive RA patients with the SE HLA Class II risk alleles (ie, SE+). - clinical response (ACR50) at Week 24 in the whole study population of early, seropositive RA patients. - clinical remission criteria (CDAI remission) at Week 24 in early, seropositive RA patients with the SE HLA Class II risk alleles (ie, SE+). - improvement in pain at Week 24 in early, seropositive RA patients with the SE HLA Class II risk alleles (ie, SE+).
To determine: - the efficacy over time by treatment in early, seropositive RA patients (SE+ subset and whole population). - the improvement in health-related quality of life over time by treatment in early, seropositive RA patients (SE+ subset and whole population). |
Comparar la eficacia de abatacept con adalimumab, ambos con MTX de base, para alcanzar: - criterios de remisión clínica (remisión DAS28-PCR) la semana 24 en pacientes con AR precoz, seropositiva, con alelos de riesgo de clase II del HLA para el EC (EC+) - respuesta clínica (ACR50) la semana 24 en la población total del estudio de pacientes con AR precoz, seropositiva. - criterios de remisión clínica (remisión CDAI) la semana 24 en pacientes con AR precoz, seropositiva, con alelos de riesgo de clase II del HLA para el EC (EC+) - mejoría en el dolor la semana 24 en pacientes con AR precoz, seropositiva, con alelos de riesgo de clase II del HLA para el EC (EC+)
Determinar: - eficacia a lo largo del tiempo por tratamiento en pacientes con AR precoz, seropositiva (subgrupo EC+ y población total) - mejoría en la calidad de vida relacionada con la salud a lo largo del tiempo por tratamiento en pacientes con AR temprana, seropositiva (subgrupo EC+ y población completa) |
