SAN DIEGO, April 6, 2011 /PRNewswire/ -- Optimer Pharmaceuticals, Inc. (NASDAQ: OPTR) and Cubist Pharmaceuticals, Inc. (NASDAQ: CBST) today announced the signing of an exclusive two-year co-promotion agreement to market DIFICID™ (fidaxomicin), in the United States. DIFICID is a novel antibiotic currently being reviewed for market approval by the FDA for the treatment of Clostridium difficile infection (CDI), which is also known as Clostridium difficile-associated diarrhea (CDAD). On April 5, 2011, the FDA's Anti-Infective Drugs Advisory Committee voted unanimously that the clinical evidence submitted by Optimer demonstrated the safety and effectiveness of DIFICID for the treatment of CDI, thereby recommending approval of DIFICID as a treatment for CDI. The FDA is expected to complete its review of DIFICID and deliver a decision on market approval by a Prescription Drug User Fee Act (PDUFA) goal date of May 30, 2011.
Under the terms of the agreement, Optimer and Cubist will co-promote DIFICID to physicians, hospitals, long-term care facilities and other healthcare institutions in the United States. Optimer and Cubist will also jointly provide medical affairs support for the product. Optimer plans to strategically build its sales force and medical affairs team. Optimer's team will be complemented by Cubist's existing U.S. hospital sales force and medical affairs team which is already dedicated to the antibiotic space for CUBICIN® (daptomycin for injection), Cubist's therapy for Staphylococcus aureus bacteremia, including right-sided endocarditis, and complicated skin infections caused by certain Gram-positive bacteria, including MRSA.
"Cubist has a proven track record and well established relations with all stakeholders involved in the antibiotics space. We believe this collaboration will maximize the impact of and de-risk DIFICID's U.S. commercial launch, assuming approval," said Pedro Lichtinger, President and CEO of Optimer. "Optimer plans to hire 100 sales representatives to target the 1,100 hospitals, which comprise about 70% of U.S. hospital CDI cases. We also believe this collaboration with Cubist will allow us to accelerate formulary adoption, expand our market reach and penetration to up to 2,000 hospitals, comprising over 90% of U.S. hospital CDI cases, and commit resources to long-term care facilities that comprise approximately one-third of all CDI cases. In addition, this provides the opportunity to capture the undiagnosed CDI market segment which some estimate to be as many as three million cases per year."
Cubist's President and CEO Michael Bonney said, "We believe that the strengths of Cubist's seasoned sales force, medical affairs team and our experience in the hospital will add tremendous value to Optimer's launch strategy and execution. We look forward to working with Optimer to introduce a much needed therapy for seriously ill patients suffering from CDAD."
The agreement expires two years from the first commercial sale of DIFICID. The agreement can be renewed for additional terms upon agreement of the parties and can be terminated early by either party in certain defined situations. Optimer will be responsible for the manufacturing and distribution of DIFICID in the United States and for recording product revenue. Optimer will be responsible for obtaining FDA approval, and will retain ownership of the New Drug Application. For its efforts under the co-promotion agreement, including providing specified levels of resources and activities, Cubist will receive quarterly service fees of $3.75 million ($15 million per year) over the two years beginning with the first commercial sale of DIFICID. Cubist is also eligible to receive an additional $5 million in the first year after first commercial sale and $12.5 million in the second year of the agreement if mutually agreed upon annual sales targets are achieved, as well as a portion of Optimer's gross profits from any sales above the specified annual sales target levels.

About DIFICID™ (Fidaxomicin)
DIFICID™ (fidaxomicin) is an investigational antibiotic with a novel mechanism of action, which inhibits the bacterial enzyme RNA polymerase, resulting in the rapid killing of C. difficile. The narrow-spectrum profile of DIFICID eradicates C. difficile selectively with minimal disruption to the normal intestinal flora, while the alternative antibiotics used to treat CDI, metronidazole and vancomycin, have been shown to disrupt the gut flora. DIFICID facilitates the return of normal physiological conditions in the colon which may be responsible for reducing CDI recurrence rates. In two Phase 3 trials for the treatment of CDI, DIFICID was equally effective in clinical cure when compared to vancomycin, the only FDA approved product for CDI. DIFICID also demonstrated statistically significant reduction in recurrences and an increase in global cure rate, defined as cure without recurrence. Importantly, DIFICID reduced the risk of recurrence by 47% compared to vancomycin. The New England Journal of Medicine has published results from the first Phase 3 trial in an article titled, "Fidaxomicin versus Vancomycin for Clostridium difficile Infection," which appeared in the February 3, 2011 issue. Optimer filed a marketing application in the EU for DIFICID for the treatment of CDI and reducing risk of recurrence when used for treatment of initial CDI.
About Clostridium difficile Infection (CDI)
Clostridium difficile infection (CDI), commonly referred to as "C. difficile" or "c-diff", has become a significant medical problem in hospitals, long-term care facilities, and in the community and is estimated to afflict more than 700,000 people each year in the U.S. It is a serious illness resulting from infection of the inner lining of the colon by C. difficile bacteria, which produce toxins that cause inflammation of the colon, severe diarrhea and, in the most serious cases, death. Patients typically develop CDI from the use of broad-spectrum antibiotics that disrupt normal gastrointestinal (gut) flora, thus allowing C. difficile bacteria to flourish and produce toxins.
Current therapeutic options for CDI include the off-label use of metronidazole and oral vancomycin, the latter being the only FDA-approved treatment. However, approximately 20% to 30% of CDI patients who initially respond to these treatments experience a clinical recurrence following cessation of the CDI treatment.
Primary risk factors for CDI include broad-spectrum antibiotic use (such as cephalosporins and fluoroquinolones), older age (over 65) and exposure to emerging hyper-virulent strains (BI/NAP1/027, 078, 001) of C. difficile. The rise in incidence of CDI, along with high rates of both treatment failures and recurrences with current therapies has resulted in greater awareness and concern about CDI among medical professionals and public health officials.
