Acept treatment resumptionThe imply time to resumption of abatacept therapy was determined in the discontinuation group.SafetyPatients remaining on abatacept have been monitored for adverse events (AEs) all through the study period. Within the discontinuation group, AE monitoring was done only if and soon after abatacept was resumed following relapse. To investigate the partnership involving the immunogenicity of abatacept and its tolerability, the anti-abatacept antibody titre in blood was measured in the time of discontinuation, time of resumption and 24 weeks following resumption of abatacept, if Bcr-Abl web applicable.Efficacy outcomes Statistical analysisMissing data had been imputed by linear extrapolation (radiographic assessments) or last observation carried forward (LOCF) (other efficacy variables). Continuous metric data have been summarized in terms of descriptive statistics and were expressed because the mean (S.D.). Data in between the two groups had been compared making use of Wilcoxon’s rank sum test (demographic and baseline characteristics, DAS28, HAQ-DI, SS, E and SN) or Fisher’s precise test Of the 34 sufferers who discontinued abatacept at enrolment, 22 individuals from an intention-to-treat (ITT) analysis (64.7 ) remained biologic-free following 52 weeks. When the mean DAS28-CRP score remained constant within the continuation group, it steadily increased over time inside the discontinuation group, major to a substantial distinction involving the groups at week 52 (2.9 vs two.0, P = 0.012). This was also accurate when the subgroup of discontinuing sufferers who remained in the study and never ever restartedFIG. 1 Patient dispositionrheumatology.oxfordjournals.orgTsutomu Takeuchi et al.TABLE 1 Patient characteristicsDiscontinuation (n = 34) Age, mean (S.D.), years Male, n ( ) Female, n ( ) RA disease duration, mean (S.D.), years DAS28-CRP, imply (S.D.)
