GCR-3888 and GCR-8015 were discovered and initially developed by the ], which is part of the U.S. ]. Genencor licensed the candidates for ] and entered into a ] (CRADA) with the NIH, which will now be continued by CAT. Under the original
license agreement with the NIH, CAT gained the rights to a portfolio of intellectual property associated with the programs and would pay future royalties to the NIH.

CAT intended to file an ] (IND) application for GCR-8015 in various CD22 positive B-cell malignancies, including ] and ], following a period of manufacturing development which is expected to be complete by the end of 2006 and to support the NCI's ongoing development of GCR-3888 in ] (HCL) and pediatric ] (pALL).<ref name="prnewswire.com"/>
