CMS Grants New Technology Add-on Payment to DIFICID® for Treatment of Clostridium difficile-associated Diarrhea

SAN DIEGO, Aug. 2, 2012 /PRNewswire/ -- Optimer Pharmaceuticals, Inc. (Nasdaq: OPTR) today announced that the Centers for Medicare & Medicaid Services (CMS) has granted a new technology add-on payment (NTAP) for DIFICID® tablets administered in the inpatient setting to treat Clostridium difficile-associated diarrhea (CDAD). Introduced in 2001, the CMS NTAP program is designed to support timely access of innovative therapies used to treat Medicare beneficiaries in the inpatient setting. The NTAP program is only available to new technologies demonstrating a substantial clinical improvement and meeting specific cost thresholds. The NTAP payment will provide hospitals with a payment, in addition to the standard-of-care DRG reimbursement, of up to 50% of the cost of DIFICID for a period of two to three years, effective in the fiscal year starting on October 1, 2012.  For 2013, CMS has assigned a maximum payment of $868.00. The NTAP payment is available to hospitals only for individual patient cases that are more costly than the average DRG charges.

In the final rule concerning Hospital Inpatient Prospective Payment Systems and Fiscal Year 2013, (scheduled for publication in the Federal Register on August 31, 2012), CMS states that: "After reviewing the totality of the evidence and the public comments we received, we agree with the commenters that DIFICID® (Fidaxomicin) represents a substantial clinical improvement over existing technologies. We believe that DIFICID represents a treatment option with the potential to decrease hospitalizations and physician office visits, and reduce the recurrence of CDAD, as well as to improve the quality of life for patients who have been diagnosed with CDAD." Additional information on the final rule and its discussion of NTAP and DIFICID can be found at: http://www.ofr.gov/inspection.aspx?AspxAutoDetectCookieSupport=1.

"The new technology add-on payment is important to enhancing the Medicare population's access to innovative treatments in the hospital in-patient setting, and we expect the additional reimbursement for DIFICID through the NTAP program will help defray the incremental cost of DIFICID borne by hospitals," said Pedro Lichtinger, President and CEO of Optimer Pharmaceuticals. "The aggregate hospital costs for all C. difficile infections in the U.S. exceed $8 billion. It's clear that CDAD, the most common symptom of CDI, has become a serious burden on the health care system."

About Clostridium difficile-associated Diarrhea (CDAD)
Clostridium difficile infection (CDI) 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. Clostridium difficile-associated diarrhea is the most common symptom of CDI. In recent years, C. difficile has surpassed methicillin-resistant Staphylococcus aureus (MRSA) as the leading cause of healthcare-acquired infections in community hospitals. Patients typically develop CDAD from the use of broad-spectrum antibiotics that disrupt normal gastrointestinal (gut) flora, possibly allowing C. difficile bacteria to flourish.

The incidence, mortality and medical care costs of CDI have reached historic highs.  Over the past decade, the incidence of CDI has increased five-fold in North America and eight-fold in the elderly. CDI is a significant burden on the U.S. healthcare system. In 2009, the aggregate cost for all CDI stays in hospitals was $8.2 billion, or 2.3% of all hospital costs in the U.S. In the same year, 2009, the Medicare system was responsible for about 230,000 hospital based cases of CDI.

About DIFICID® (fidaxomicin) Tablets
DIFICID is the first macrolide antibacterial drug indicated for Clostridium difficile-associated diarrhea (CDAD) to be approved in over 25 years in the U.S.  It is indicated for the treatment of CDAD in adults 18 years of age or older. DIFICID is administered in 200 mg tablets given orally twice daily.

Important Safety Information for DIFICID
DIFICID should not be used for systemic infections. Only use DIFICID for infection proven or strongly suspected to be caused by C. difficile. Prescribing DIFICID in the absence of a proven or strongly suspected C. difficile infection is unlikely to provide benefit to the patient and increases the risk of the development of drug resistant bacteria. The most common adverse reactions are nausea (11%), vomiting (7%), abdominal pain (6%), gastrointestinal hemorrhage (4%), anemia (2%) and neutropenia (2%).
