Seropositive patients switching from adalimumab to Orencia showed trend toward higher efficacy at week 48

Bristol Myers Squibb announced results from the open-label switch period of Early AMPLE, a Phase IV exploratory biomarker study assessing the differences by which Orencia (abatacept) and another treatment, adalimumab, interfere with disease progression in moderate-to-severe early rheumatoid arthritis (RA) patients who tested positive (seropositive) for certain autoantibodies. Findings of the open-label switch period showed that early seropositive RA patients treated with Orencia demonstrated substantial clinical improvements at week 48, sustaining the level of responses achieved at week 24 compared to adalimumab. In seropositive patients switching from adalimumab to Orencia, the efficacy responses generally increased over the open-label period to week 48. These results are featured in a poster presentation at the European E-Congress of Rheumatology (EULAR) 2020.
