Clinical Development - Zavesca®
Zavesca® trials ongoing
Zavesca® is registered for the treatment of type 1 Gaucher's disease, a genetically inherited disorder of lipid metabolism. Failure to metabolize glycosphingolipids leads to excess accumulation in cells, particularly in the liver, spleen and bone marrow – resulting in enlarged organs and marrow and bone abnormalities. Zavesca® provides a novel approach to the treatment of Gaucher’s disease by inhibiting the formation of glucosylceramide, an important element in the formation of these lipids. An added advantage of Zavesca® is that it is an oral treatment and therefore may be more suitable for those patients who are unable to receive enzyme replacement therapy.
There is strong preclinical evidence to support the use of Zavesca® in other related lipid storage diseases for which currently no therapy exists. Consequently, Phase III trials in Niemann-Pick Type C, Late Onset Tay-Sachs and Type 3 Gaucher’s are being conducted. Results of these studies will be available in late 2004 and 2005.
