E.2 Objective of the trial |
E.2.1 | Main objective of the trial |
The primary objective for this study is to compare the clinical efficacy of weekly abatacept in combination with MTX to MTX alone in achieving Remission, defined as SDAI ? 3, at Week 24. |
El objetivo principal de este estudio es comparar la eficacia clínica de abatacept semanal en combinación con MTX con MTX solo para conseguir la remisión, definida como SDAI ? 3, en la semana 24. |
|
E.2.2 | Secondary objectives of the trial |
1) To compare the efficacy of weekly abatacept + MTX to MTX alone in achieving remission by DAS28-CRP Remission criteria at Week 24. 2) To compare the efficacy of weekly abatacept + MTX to MTX alone in achieving remission by SDAI remission criteria at Week 52. 3) To compare the efficacy of weekly abatacept + MTX to MTX alone in reducing joint damage by X-ray at Week 52. 4) To compare the efficacy of weekly abatacept + MTX to MTX alone in achieving remission by Boolean remission criteria at Week 52. |
1)Comparar la eficacia de abatacept semanal + MTX con MTX solo para conseguir la remisión según los criterios de remisión DAS28-PCR en la semana 24. 2)Comparar la eficacia de abatacept semanal + MTX con MTX solo para conseguir la remisión según los criterios de remisión SDAI en la semana 52. 3)Comparar la eficacia de abatacept semanal + MTX con MTX solo para reducir el daño articular según evaluación radiográfica en la semana 52. 4)Comparar la eficacia de abatacept semanal + MTX con MTX solo para conseguir la remisión según los criterios de remisión booleana en la semana 52. |

E.2.3 | Trial contains a sub-study | Yes |
E.2.3.1 | Full title, date and version of each sub-study and their related objectives |
The MRI sub-study is presented in section 5.4.1.2 of the original IM101-550 protocol dated 08-MAY-2015.
MRI will be performed as a sub-study on about 80 subjects from selected qualified sites in selected countries. The purpose of this sub-study is to further inform the mechanism of action and efficacy of abatacept in Early RA by obtaining sensitive imaging at early time-points prior to those when traditional x-ray imaging would be expected to demonstrate significant change due to disease. |
El subestudio de RMI se presenta en la sección 5.4.1.2 del protocolo original IM101-550 de fecha 08-may-2015. El estudio de RMI se realizará como un subestudio en aproximadamente 80 sujetos de centros cualificados en países seleccionados. El objetivo de este subestudio es conocer mejor el mecanismo de acción y la eficacia de abatacept en la AR temprana obteniendo imágenes sensibles en puntos temporales tempranos anteriores a aquellos en los que en una imagen radiográfica tradicional cabría esperar un cambio significativo debido a la enfermedad. |
