Clinical Trial Summary

Eculizumab is an anti-C5 monoclonal antibody approved for rare diseases including atypical haemolytic-uraemic syndrome. The maintenance phase dosing regimen is identical for all adult patients but several studies have shown a high interindividual kinetics variability. A tailored administration of eculizumab based on therapeutic drug monitoring will be compared with real-life administration in adults suffering from an atypical haemolytic uraemic syndrome. The objective is to improve efficiency of eculizumab administration.


Clinical Trial Description

Eculizumab is a very expensive drug (450 000 euros per year per patient). According to the usual administration scheme, the eculizumab is administrated by intravenous infusion, every 14 or 21 days in hospital. Studies have shown the possibility of extending the administration intervals in patients with a high concentration of eculizumab. A personalized spacing of eculizumab infusions, based on a therapeutic drug monitoring, is expected to improve the patient's quality of life and lead to substantial savings. For these reasons, the objective of this study is to explore the efficiency of a personalized spacing of eculizumab infusions compared to the usual administration scheme (without personalization) from the French health Insurance perspective. The efficiency will be assessed by estimating the incremental cost per QALY (Quality-Adjusted Life Year) gained at 18 months (duration of follow-up in the clinical trial) and at 5 years thanks to a Markov model. The total duration of the study is 24 months (6 months of enrolment and 18 months of follow-up). ;
