Cubist Pharmaceuticals, Inc. (NASDAQ: CBST) today announced that it has received a Paragraph IV Notice Letter from Hospira, Inc. advising of the filing of an Abbreviated New Drug Application (ANDA) for a generic version of CUBICIN® (daptomycin for injection).
CUBICIN is currently protected by five FDA Orange Book-listed patents, which expire between 2016 and 2028. Hospira’s Notice Letter is directed to all of the patents listed in the Orange Book.
Cubist intends to vigorously enforce its extensive intellectual property rights for CUBICIN and plans to file a complaint alleging infringement within the required 45-day response period of the Hatch-Waxman Act. Once a suit is filed, a 30-month stay of approval will be imposed by the FDA on Hospira's ANDA.
In April 2011, Cubist announced it had settled its CUBICIN patent litigation with Teva Pharmaceuticals. As part of that settlement, Cubist granted Teva a license to sell generic daptomycin in the U.S. either as of June 24, 2018, if CUBICIN is granted pediatric exclusivity extension, or as of December 24, 2017. In addition, as part of this settlement, Teva will purchase its U.S. requirements of daptomycin exclusively from Cubist.
Since the settlement with Teva, Cubist has been granted two additional patents that are listed in the Orange Book: US Patent No. 8,003,673, which expires on September 4, 2028, and US Patent No. 8,058,238, which expires on November 28, 2020.
CUBICIN® (daptomycin for injection) is approved in the U.S. and many other non-US markets as therapy for
Staphylococcus aureus bloodstream infections (bacteremia), including right-sided endocarditis, caused by methicillin-resistant
S. aureus (MRSA) and methicillin-susceptible
S. aureus (MSSA), and complicated skin infections caused by certain Gram-positive bacteria, including MRSA. 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.
