The objective of this study is to assess Elelyso treatment on bone disease in Gaucher patients currently treated with other enzyme replacement therapy.
Experience from early access program (2009-2012) has suggested that some patients who have been stable on imiglucerase have shown poor scores of QCSI with Fat Fraction below the cut off point of 0.23 which is considered "bone at risk", and have demonstrated remarkable improvement upon switching to Elelyso, including particularly 2 patients who did not have any change in dose or any drug interruption prior to the switch.
These findings may be explained by the better glycan structure of imiglucerase (see Tekoah et al, 2013). The fact that in many patients prevention of bony complications is the main indication for ERT highlights the importance of this study, as all clinical trials of all ERTS heretofore did not include the bones as primary or secondary end-points but only as exploratory, and as such had only limited value,
Open-label study in patients with Gaucher disease currently treated with commercial ERTs. Eligible patients will receive intravenous (IV) infusions of Elelyso every two weeks. The infusions will be administered at the selected medical center or in the home care setup. The dose of Elelyso will be the same dose of the other ERTs . Bone parameters QCSI and BMD will be assessed at baseline, 12 months and 24 months.
The intention is to open 3 more sites in Israel thereby making this IIR a multi center national trial
