Medico-economic evaluation of infliximab in rheumatoid arthritis—prospective French study of a cohort of 635 patients monitored for two years

Objectives. To perform, in real conditions of prescription, the medico-economic evaluation of infliximab in severe RA. Methods. A cost-effectiveness analysis of the annual costs was done with a comparison between the previous and the following year under infliximab. The effectiveness, determined from the HAQ, was expressed in clinically significant units and in quality-adjusted life years (QALYs). The incremental net benefit (INB), defined as willingness to pay (λ), was used to express the results. Results. A cohort of 635 patients was formed. Before the use of infliximab, after 1 and 2 years, the mean annual cost per patient for the care of RA was €9832, 27 723 and 46 704, respectively. Among the direct costs, infliximab accounts for €21 182 for the first year. The distribution of the different costs was similar after 2 years. By using the INB, the difference before and after 1 year under infliximab is significant, on average by 1.86 (s.e.m. = 0.76) when the effectiveness is expressed in clinically significant units. For severe HAQ, λ is €9841 (18 593 for all HAQ). When it is expressed in QALYs, also for severe HAQ, λ >€100 000. This can be explained by a short follow-up although severe complication of RA appears later. Conclusion. An evaluation of the more long-term costs is required in order to determine whether there are any full economic benefits with this treatmen

Optimizing the use of anti-interleukin-6 monoclonal antibody with dexamethasone and 140 mg/m2 of melphalan in multiple myeloma: results of a pilot study including biological aspects.

International audienceInterleukin-6 (IL-6) is a major survival factor for multiple myeloma (MM) cells preventing apoptosis induced by dexamethasone (DEX) or chemotherapy. In all, 24 consecutive patients with MM in first-line therapy received DEX for 4 days, followed by melphalan (HDM: 140 mg/m2) and autologous stem cell transplantation (ASCT). The anti-IL-6 monoclonal antibody (mAb) (B-E8) was given till haematological recovery, starting 1 day before DEX. Results were historically compared to MM patients treated with HDM 140 and 200 mg/m2. Our results show (1) that B-E8 was able to fully neutralize IL-6 activity in vivo before and after HDM as shown by inhibition of C reactive protein (CRP) production; (2) no haematological toxicity; (3) a significant reduction of mucositis and fever; (4) a median event-free survival of 35 months and an overall survival of 68.2% at 5 years with a median follow-up of 72 months; and (5) the overall daily IL-6 production progressively increased on and after 7 days post-HDM, with the increased serum CRP levels. In the 5/24 patients with uncontrolled CRP production, a large IL-6 production was detected (320 microg/day) that could not possibly be neutralized by B-E8. These data show the feasibility to neutralize IL-6 in vivo with anti-IL-6 mAb in the context of HDM
