Trial Outcomes & Findings for Efficacy, Pharmacokinetics, Safety, and Immunogenicity Study of Abatacept Administered Subcutaneously to Treat Rheumatoid Arthritis in Japanese Patients (NCT NCT01001832)

NCT ID: NCT01001832

Last Updated: 2014-02-06

Results Overview

The ACR score of 20 indicates the degree of improvement in a patient's rheumatoid arthritis (RA), based on ACR guidelines (ACR20). The ACR score represents a percentage. To qualify for an ACR20 score, the patient must have \>=20% fewer tender joints and \>=20% fewer swollen joints and show 20% improvement in at least 3 of: patient overall assessment of his/her RA, physician global assessment of the patient's RA, patient self-assessment of pain, patient self-assessment of physical functioning, and results of an erythrocyte sedimentation rate or C-reactive protein test (to assess inflammation). Percentage is calculated n/N with n=number of participants with ACR score of 20 and N= all randomized participants who received at least one dose of study drug.

Treatment groups represent treatment received in the short term period. Percentage calculated as n/m with n=number of paticipants with sustained ACR response at Day 533; m= long term participants who received at least one dose of drug and were ACR responders in the short term period.

PRIMARY outcome

Timeframe: Baseline to Day 533

Population: Number of participants with both baseline and post-baseline measurements in HAQ-DI. Treatment groups represent treatment received in the short term period.

Adjusted mean. The Health Assessment Questionnaire Disability Index (HAQ-DI) assesses patients' functional ability by rating their abilities over the previous week. At least 2 questions are asked from each of 8 categories: dressing and grooming, hygiene, arising, reach, eating, grip, walking, and common daily activities. Patients rate difficulty performing specific tasks: 0=without difficulty, 1=with some difficulty, 2=with much difficulty, and 3=unable to do. The sum of the categories score (the highest scored item in the category) is divided by the number of categories answered, yielding a score from 0-3. Treatment groups represent treatment received in the short term period. Baseline is Day 1 of the study or last non-missing pre-treatment value.

The Health Assessment Questionnaire (HAQ) disability index assesses patients' functional ability by rating their abilities over the previous week. At least 2 questions are asked from each of 8 categories: dressing and grooming, hygiene, arising, reach, eating, grip, walking, and common daily activities. Patients rate difficulty performing specific tasks: 0=without difficulty, 1=with some difficulty, 2=with much difficulty, and 3=unable to do. The higher the number the worse the outcome. The sum of the categories score (the highest scored item in the category) is divided by the number of categories answered, yielding a score from 0-3.

The Disease Activity Score 28 using C-Reactive Protein (DAS28-CRP) is a measure of disease activity in rheumatoid arthritis (RA) and assesses the 28 joints RA commonly affects; the score includes the number of tender and swollen joints (out of 28), CRP level (a measure of inflammation in the blood), and the patient's global assessment of health (ranging from very good to very bad). An overall DAS \>5.1 implies active disease; \<3.2, well controlled disease; and \<2.6, remission.). Treatment groups represent treatment received in the short term period.
