OSI Pharmaceuticals, Inc and Genentech, Inc, a wholly owned member of the Roche Group, announced that the US Food and Drug Administration (FDA) has extended the review period for the supplemental New Drug Application (sNDA) for Tarceva (erlotinib) as a first-line maintenance therapy in advanced non-small cell lung cancer (NSCLC) by an additional 90 days. The extension follows OSI's submission of further data in support of the application. The original Prescription Drug User Fee Act (PDUFA) date was January 18, 2010. The companies now anticipate US FDA action on the sNDA by April 18, 2010.

OSI and Genentech will work closely with the US FDA during this extended review period.
