Updated long-term safety profile of rituximab
A recent analysis by van Vollenhoven et al entitled Long-term safety of rituximab: Follow-up of the rheumatoid arthritis (RA) clinical trials and retreatment population was presented at the ACR 2009 conference. This analysis examined the long-term safety profile of rituximab in the largest patient population to date—3095 patients from 8 controlled and 2 open-label extension RA clinical trials. The investigators found that rituximab had a consistent safety profile, with no increase in serious infections over multiple courses. Additionally, the proportion of patients with infusion reactions was shown to decrease over multiple courses.
Please note: Care should be exercised in interpreting open-label results due to the inability to minimize bias.
In this video, Dr. Alan Bridges of the University of Wisconsin School of Medicine will walk you through the highlights of this analysis.
Considerations for switching patients after inadequate response to TNFi treatment
An analysis by Finckh and colleagues titled Which subgroup of patients with rheumatoid arthritis benefits from switching to rituximab versus subsequent anti-tumour necrosis factor (TNF) agents after previous failure of an anti-TNF agent? was published in the Annals of Rheumatic Diseases. This study examined the effectiveness of switching to a therapy with a different MOA, like rituximab, versus subsequent TNFi in different subgroups of TNFi patients. The authors report that the improvement in disease activity was significantly better in patients treated with rituximab versus a subsequent TNFi when the reason for switching was TNFi-inadequate response. When patients were switched due to other causes (including AEs), the improvement in disease activity was similar between rituximab and a subsequent TNFi.
In this video, Dr. Kevin Latinis of Kansas University Medical Center will guide you through the findings of this important study.
Please note: Care should be taken when interpreting these data, as they constitute the results of an uncontrolled observational study based on registry data. The study was not powered to detect differences in efficacy between therapies. No comparison of safety and efficacy is intended with any specific TNFi agent.
Other studies have given additional perspectives on switching from TNF inhibitors, including the Karlsson review, which shows response rates with successive TNF inhibitors.

Safety of biologics used after Rituxan by Dr. Mark Genovese and colleagues
Dr. Daniel Furst of the UCLA Medical Center presents an analysis published by Dr. Mark Genovese and colleagues' research describing the rate of serious infections in Rituxan patients who subsequently received treatment with another biologic therapy.
Please note: Limited data are available on the safety of the use of biologic agents or DMARDs other than methotrexate in patients exhibiting peripheral B-cell depletion following treatment with rituximab. Observe patients closely for signs of infection if biologic agents and/or DMARDs are used concomitantly.
