Kuvan Receives Priority Review Status from FDAPDUFA Date Set for November 25, 2007
NOVATO, Calif., July 25 (HSMN NewsFeed) -- BioMarin Pharmaceutical Inc. (Nasdaq and SWX: BMRN News) announced today that the U.S. Food and Drug Administration (FDA) has accepted for filing and granted priority review status to the New Drug Application (NDA) for Kuvan(TM) (sapropterin dihydrochloride). Under the Prescription Drug User Fee Act (PDUFA), the FDA is expected to take action on the application by November 25, 2007. Kuvan, an investigational oral small molecule for the treatment of phenylketonuria (PKU), a rare genetic metabolic disorder, is being developed in partnership with Merck Serono, a division of Merck KGaA, Darmstadt, Germany.
Priority review is typically granted to drugs that, if approved, will provide a significant improvement in the safety or effectiveness of the treatment, diagnosis, or prevention of a serious or life-threatening disease. Kuvan has also been granted orphan drug designation, which is conferred upon investigational products for diseases that affect fewer than 200,000 patients in the United States. Products with orphan drug designation that are the first to be approved for a specific indication have seven years market exclusivity in the U.S.
Kuvan is an investigational oral small molecule therapeutic for the treatment of PKU. The active ingredient in Kuvan, sapropterin dihydrochloride, is the synthetic form of 6R-BH4 (tetrahydrobiopterin), a naturally occurring enzyme cofactor that works in conjunction with phenylalanine hydroxylase (PAH) to metabolize Phe. Clinical data suggest that treatment with Kuvan results in significant reductions in blood Phe levels in BH4-responsive patients. It also may enable some patients to minimize or eliminate highly-restrictive dietary constraints by increasing Phe tolerance levels. BioMarin and Merck Serono estimate that Kuvan could be a potential treatment option for approximately 30 percent to 50 percent of the estimated 50,000 identified PKU patients in the developed world.
Kuvan has received orphan drug designation from both the U.S. Food and Drug Administration (FDA) and the European Medicines Agency (EMEA). If approved, it will receive seven years of market exclusivity in the United States and 10 years in the European Union for this indication. Additionally, the FDA has granted Kuvan Fast Track designation, which is designed to facilitate the development of new drugs that are intended to treat serious or life-threatening conditions and that demonstrate the potential to address unmet medical needs.
PKU, a genetic disorder affecting approximately 50,000 diagnosed patients in the developed world, is caused by a deficiency of the enzyme phenylalanine hydroxylase (PAH). PAH is required for the metabolism of phenylalanine (Phe), an essential amino acid found in most protein-containing foods. If the active enzyme is not present in sufficient quantities, Phe accumulates to abnormally high levels in the blood and becomes toxic to the brain, resulting in a variety of complications including severe mental retardation and brain damage, mental illness, seizures, tremors, and limited cognitive ability. As a result of newborn screening efforts implemented in the 1960s and early 1970s, virtually all PKU patients under the age of 40 in developed countries have been diagnosed at birth. Currently, PKU can only be managed by a Phe- restricted diet, which is supplemented by nutritional replacement products, like formulas and specially-manufactured foods; however, the strict diet is difficult for most patients to adhere to the extent needed for achieving adequate control of blood Phe levels.
