Isis Announces $1.2 Million Award to Its Ibis Subsidiary to Expand Influenza Detection Capabilities and Enable Large-Scale Influ

Sept. 26, 2007

CARLSBAD, Calif., Sept. 26 /PRNewswire-FirstCall/ -- Isis Pharmaceuticals, Inc. (Nasdaq: ISIS) announced today that its wholly owned subsidiary, Ibis Biosciences, Inc. (Ibis), has been awarded a subcontract of a National Institutes of Health (NIH) grant to aid in influenza surveillance research through application of the Ibis T5000(TM) Biosensor System. The NIH grant, applied for jointly by Ibis and the Lovelace Respiratory Research Institute (LRRI) and subcontracted to Ibis by LRRI, provides funding for research studies, including assay development, and sample characterization in order to expand the understanding of transmission of influenza viruses, including the highly pathogenic H5N1 avian influenza viral strain.

"We are excited to be working with the Lovelace Respiratory Research Institute, a world leader in respiratory disease surveillance, to aid in understanding the transmission of influenza viruses," said Michael Treble, President of Ibis and Vice President of Isis. "Our service laboratory capabilities provide us the flexibility to support important and diverse projects, such as this one with the LRRI. Consistent with our business model, with this government funding we will not only fulfill the grant's specified research and screening activities, but we will also be able to incorporate any results and assay kit improvements into our commercial offerings."

The award to Ibis will fund the development of expanded influenza detection capabilities with assays to uniquely identify and characterize influenza strains and aid in the tracking of influenza transmissions. Additionally, because of the high-throughput, cost-effective and highly specific characteristics of the Ibis T5000 Biosensor System, as part of the funded research, Ibis will be analyzing a large number of samples generated from the influenza surveillance research.

"This grant will enable us to continue to advance our research in understanding the transmission of viral particles in order to prevent pandemic spread of virulent respiratory diseases, including influenza," said Frederick T. Koster, M.D., Associate Scientist, Infectious Diseases Program, Lovelace Respiratory Research Institute. "In order to screen large numbers of biological samples, we needed a technology partner that could provide high-resolution characterization of closely related viral strains, and could do so with appropriate sensitivity and high-throughput efficiency."

Respiratory diseases such as asthma, emphysema, influenza, and chronic bronchitis are on the increase worldwide. LRRI, one of the nation's largest independent research institutions and the only one focused solely on respiratory health, is committed to eradicating respiratory diseases through research aimed at understanding their causes and biological mechanisms, eliminating exposures to causal agents and developing more effective treatments.

Ibis' universal flu surveillance capabilities were described in a recent research study published in PLoS ONE in May 2007 . In the study, Ibis' Dr. Sampath and colleagues report that they detected and correctly identified 92 mammalian and avian influenza isolates, including 29 avian H5N1 isolates. They also analyzed 656 human respiratory samples and showed correct, simultaneous identification of the viral species and subtypes with greater than 97 percent sensitivity and specificity.

ABOUT THE IBIS T5000 BIOSENSOR SYSTEM AND IBIS BIOSCIENCES, INC.

Ibis Biosciences, Inc., a wholly owned subsidiary of Isis Pharmaceuticals, has developed the Ibis T5000(TM) Biosensor System for rapid identification and characterization of infectious agents. The Ibis T5000 is capable of identifying virtually all bacteria, viruses and fungi, and can provide information about drug resistance, virulence and strain type of these pathogens. Commercial applications for the Ibis T5000 Biosensor System include epidemiologic surveillance, monitoring of pandemic diseases, identification of emerging or previously unknown pathogens, forensic characterization of human samples, identification of sources of hospital-associated infections, and, in the future, human infectious disease diagnostics. Bruker Daltonics, a subsidiary of Bruker BioSciences Corporation, is globally responsible for manufacture, order processing, installation and service of Ibis T5000 instruments. Ibis Biosciences develops, manufactures and markets Ibis T5000 assay kits.
