Positive Opinion for Expanded Label of CUBICIN Received from European Regulatory Authority; Decision Expected This September

EMEA Scientific Committee Reviewed Data from Cubist's Landmark Phase 3 Trial of Staphylococcus aureus Bacteremia and Endocarditis

LEXINGTON, Mass.--(HSMN NewsFeed)--Cubist Pharmaceuticals, Inc. (NASDAQ: CBST ) today reported that the Committee for Medicinal Products for Human Use (CHMP), the scientific committee of the European Agency for the Evaluation of Medicinal Products (EMEA), has issued a positive opinion recommending approval of an expanded Marketing Authorization for CUBICIN ® (daptomycin for injection). The CHMP positive opinion, issued by the EMEA on July 19th, recommends expansion of the CUBICIN label to include right-sided infective endocarditis (RIE) due to Staphylococcus aureus (S. aureus) as well as S. aureus bacteremia (SAB) when associated with RIE or with complicated skin and soft-tissue infections (cSSTI). The Marketing Authorization Holder for CUBICIN in Europe is Novartis. CUBICIN was originally approved by the EMEA in January of 2006 for cSSTI caused by Gram-positive bacteria.

Mike Bonney, President and Chief Executive Officer of Cubist, said: "This is another important milestone for CUBICIN in Europe and reflects the dedicated efforts of the Novartis team, with support from Cubist, in preparing the file for submission and responding quickly to questions from the committee."

The positive opinion from the CHMP is the final step before formal approval of a variation to the terms of the marketing authorization for CUBICIN in the 27 member states of the European Union, Iceland, Liechtenstein and Norway. The CHMP is a scientific body that reviews medicinal product applications on their scientific and clinical merit and provides advice on their approval to the European Commission (EC), including recommendations about product labeling. The final decision regarding an expanded label for CUBICIN in the EU will be made by the European Commission and is expected in September.

Novartis is authorized, through an exclusive license agreement, to develop and commercialize CUBICIN in Western and Eastern Europe, Australia, New Zealand, India, and certain Central American, South American and Middle Eastern countries. Under the terms of the agreement, Novartis is responsible for regulatory filings in those territories.


CUBICIN is currently the only once-daily bactericidal antibiotic approved in the U.S. for the treatment of complicated skin and skin structure infections caused by susceptible strains of the following Gram-positive microorganisms: Staphylococcus aureus (including methicillin-resistant strains), Streptococcus pyogenes, S. agalactiae, S. dysgalactiae subsp equisimilis and Enterococcus faecalis (vancomycin-susceptible strains only). CUBICIN is also approved in the U.S. as therapy for bloodstream infections (bacteremia), including right-sided endocarditis, caused by S. aureus. CUBICIN is not indicated for the treatment of pneumonia. Most adverse events reported in clinical trials were mild to moderate in intensity. The most common were anemia, constipation, diarrhea, nausea, vomiting, injection site reactions, and headache. To reduce the development of drug-resistant bacteria and maintain the effectiveness of CUBICIN, CUBICIN should be used only to treat or prevent infections that are proven or strongly suspected to be caused by bacteria susceptible to CUBICIN.
