Objective. To assess the efficacy and safety of abatacept for secondary SjOgren's syndrome (SS) Methods. The primary endpoint of this 1-year, open-labeled, prospective, observational multicenter study of RA-associated secondary SS was the rate of SDAI remission at 52 weeks after initiation of abatacept therapy. The secondary endpoints included that of Saxson's test and Schirmer's test. Adverse events during the study period were also analyzed. Results. Thirty-two patients (all females) were enrolled in this study. Interim analysis at 24 weeks included assessment of efficacy (n = 31) and safety (n = 32). The mean SDAI decreased from 19.8 +/- 11.0 (+/- SD) at baseline to 9.9 +/- 9.9 at 24 weeks (P < 0.05). Patients with clinical remission, as assessed by SDAI, increased from 0 patient (0 week) to 8 patients (25.8%) at 24 weeks. Saliva volume (assessed by Saxson's test) increased slightly from 2232 +/- 1908 (0 week) to 2424 +/- 2004 (24 weeks) mg/2 min (n = 29). In 11 patients with Greenspan grading 1/2 of labial salivary glands biopsy, saliva volume increased from 2945 +/- 2090 (0 week) to 3419 +/- 2121 (24 weeks) mg/2 min (P < 0.05). Schirmer's test for tear volume showed increase from 3.6 +/- 4.6 (0 week) to 5.5 +/- 7.1 (24 weeks) mm/5 min (n 25; P < 0.05). Five adverse events occurred in five of 32 patients (15.6%), and three of these events were infections. Conclusion. Abatacept seems to be effective for both RA and RA-related secondary SS.
