Nanosphere to Provide Additional Data to FDA for Verigene Clopidogrel Metabolism Nucleic Acid Test

/ Source: GlobeNewswire

NORTHBROOK, Ill., June 21, 2011 (GLOBE NEWSWIRE) -- Nanosphere, Inc. (Nasdaq:NSPH) announced today it will provide additional information for its premarket approval (PMA) application following the Food and Drug Administration's (FDA) issuance of a not approvable letter for the Verigene Clopidogrel Metabolism Nucleic Acid Test (Plavix Metabolism).

The Company believes the deficiencies cited in the FDA letter are resolvable and ultimately the PMA for the Plavix Metabolism test will be approved by the FDA, although there can be no assurance of such approval.

The issuance of the Letter means that the Company will encounter a delay in its plans to commercialize this product in the United States. The initial U.S. revenue ramp from this product will likely not commence until 2012, the Company said. The Plavix Metabolism test is CE IVD Marked and currently being sold in certain European markets. The Company intends to launch the product in additional European and Asian markets before the end of 2011.
