Friedhelm Blobel, SciClone Chief Executive Officer commented: “Together with our partner BTG, we will now focus our efforts on preparing for the introduction of the product in the Chinese market.

We believe DC Bead® has the potential to be a valuable addition to SciClone’s oncology product portfolio.”

Louise Makin, Chief Executive Officer at BTG, said: “Approximately half of the world’s liver cancer patients are in China and there is a great interest among Chinese physicians to offer new, differentiated treatment options.
