NOVATO, Calif., Dec. 2, 2010 /PRNewswire/ -- BioMarin Pharmaceutical Inc. (Nasdaq: BMRN) today announced that the Medicines and Healthcare Products Regulatory Agency (MHRA) in the UK has completed review of the Clinical Trial Application (CTA) and has issued a notice of acceptance for BMN 673 for genetically-defined cancers.  The company expects to initiate a Phase 1/2 trial by the first quarter of 2011.
