E.2.1 | Main objective of the trial |
To compare the effectiveness based on the achievement of minimal disease activity (MDA) at Week 16 between subjects who had adalimumab introduced and those that had methotrexate (MTX) escalated to the highest recommended dose of 20–25 mg every week (ew) or highest tolerable dose up to 25 mg ew after inadequate disease control on the initial MTX therapy. |
Comparar la eficacia basada en el logro de una actividad mínima de la enfermedad ( AME) en semana 16 entre pacientes que recibieron adalimumab y aquellos que recibieron el escalado de dosis hasta la máxima recomendada de metotrexato (MTX) de 20-25mg semanalmente o la máxima tolerada hasta 25 mg semanalmente después de un control inadecuado de la enfermedad con la terapia inicial de MTX. |

•To compare the effectiveness at Week 16 between subjects who had adalimumab introduced and those that had MTX escalated to the highest recommended dose of 20-25mg ew or highest tolerable up to 25mg ew based on following clinical, functional and quality of life measures: -Psoriatic Arthritis Disease Activity Score (PASDAS) -Disease Activity in Psoriatic Arthritis (DAPSA) score -Psoriatic Arthritis Impact of Disease (PsAID) score -American College of Rheumatology criteria (ACR) -Disease Activity Score 28 (DAS28) -Psoriasis Area and Severity Index (PASI) -Health Assessment Questionnaire Disability Index (HAQ-DI) -Short Form Health Survey 36 (SF-36) scores: total, physical component summary (PCS) and mental component summary (MCS) -Dermatology Life Quality Index (DLQI) -Leeds Enthesitis Index (LEI) -Tender dactylitic digit count •To evaluate the achievement of MDA at Week 32 on each of the four different treatment regimens involving adalimumab and/or MTX in Part 2 of the study |
