Cubist Pharmaceuticals Acquires Illumigen BiosciencesLEXINGTON, Mass. & SEATTLE--(BUSINESS WIRE)--Dec 26, 2007 - Cubist Pharmaceuticals, Inc. (NASDAQ: CBST) and Illumigen Biosciences, Inc. announced today that Cubist has acquired Illumigen pursuant to a definitive agreement and plan of merger entered into on December 24, 2007. Illumigen's lead compound is IB657, a protein therapeutic in pre-clinical development for the treatment of Hepatitis C Virus (HCV) infections. Cubist expects that an IND for IB657 will be filed in 2008.
Pursuant to the terms of the agreement, which was approved by the Boards of Directors of each company, Cubist will pay to the Illumigen stockholders $9 Million (after adjusting for Illumigen's closing cash balance) in cash and Illumigen has become a wholly-owned subsidiary of Cubist. Cubist will make payments during the development of IB657 as a therapy for HCV infections of up to $75.5 Million upon achieving certain development and regulatory milestones. If Cubist develops Illumigen products for the treatment of viruses other than HCV, development and regulatory milestone payments of up to $117 Million could apply. Assuming that HCV or other Illumigen antiviral products are commercialized, additional milestone payments of up to $140 Million, as well as tiered royalties, could apply.
Mike Bonney, President and CEO of Cubist Pharmaceuticals, said "We are excited about the opportunity of filing an IND for IB657 in the coming year and advancing it into the clinic. An HCV product candidate is an important addition to our pipeline, and leverages our antiinfective development, regulatory, and commercialization expertise."
Donald Elmer, Chairman of Illumigen Biosciences, said "We believe that Cubist is ideally positioned to exploit the immediate opportunity for IB657 against HCV, and potentially for additional viral infections."
No financing will be necessary to complete the acquisition of Illumigen or to fund the development of IB657. The impact of any charges related to purchase accounting, including in-process R&D, will be recorded in Cubist's 2007 full-year results.
HCV is a virus that primarily targets the liver, currently causing infection in more than 4 million people in the U.S. and 180 million people worldwide. The virus is difficult to eradicate, with infected patients eventually developing chronic liver infection, and, in some cases, liver cancer. HCV infection is the most common reason for liver transplantation in the U.S. and Western Europe and the leading cause of death from liver disease.
No vaccine is currently available to prevent HCV infection. Current HCV therapy combines a pegylated-interferon with ribavirin for up to 48 weeks of treatment. Current therapy has significant problems with both safety (e.g., significant treatment limiting adverse effects and contraindications) and efficacy (e.g., 80% of HCV infections in the U.S. are due to genotype 1 virus for which the efficacy rate of current therapy is approximately 40 to 50%). The HCV market was $2.2 Billion in 2005 and is projected to double to $4.4 Billion in 2010. This growth will be driven by an increase in the number of patients being treated, uptake of new drugs, and the use of multi-drug treatment regimens.
IB657 is a pre-clinical protein therapeutic being developed for treatment of HCV infection. Based on its antiviral activity, IB657 may have therapeutic utility in the treatment of certain other viral diseases. Pre-clinical studies to assess activity against these viruses may occur in parallel with its development for HCV infection.
Illumigen Biosciences, Inc. was co-founded by Drs. Charles Magness and Shawn Iadonato in 2000 to discover beneficial human genetic mutations that might provide a roadmap for novel therapeutic drug mechanisms. The discovery of IB657 resulted from an investigation into the cause of apparent immunity to HCV infection enjoyed by people with a specific naturally occurring genetic mutation. Prior to founding Illumigen, Drs. Magness and Iadonato both were involved in the Human Genome Project. Illumigen is a Seattle-based, privately held biopharmaceutical company financed by Pacific Horizon Ventures in Seattle, WA.

Cubist Pharmaceuticals, Inc. is a biopharmaceutical company focused on the research, development, and commercialization of pharmaceutical products that address unmet medical needs in the acute care environment. In the U.S., Cubist markets CUBICIN(R) (daptomycin for injection), the first antibiotic in a new class of anti-infectives called lipopeptides. The Cubist product pipeline includes pre-clinical programs that address unmet medical need in Gram-positive infections, Gram-negative infections, and CDAD (Clostridium difficile-associated diarrhea). Cubist is headquartered in Lexington, MA. Additional information can be found at Cubist's web site at www.cubist.com.
