“2008 is set to be a transformational year, with regulatory approvals of key products anticipated in both Europe and the US and important results due on two further products in Phase III US trials. The Company is strongly funded and remains on track to achieve its target of break-even during 2009, with increasing profitability thereafter generated from the growing sales of new products.”
