United States Patent Office Allows Claims Covering the Approved Administration of Kuvan with Food
NOVATO, Calif., Sept. 30 /PRNewswire-FirstCall/ –BioMarin Pharmaceutical Inc. (Nasdaq: BMRN) announced today that the United States Patent and Trademark Office has allowed claims covering the approved administration of KuvanÃ‚® (sapropterin dihydrochloride) with food, based on the discovery that food increases the bioavailability of Kuvan. The company expects that the patent, which expires in 2024, will officially issue later this year.
“This food effect patent, along with the patents issued for once daily dosing and stable tablet formulation, continues to strengthen our proprietary position on Kuvan and provides protection that extends approximately ten years beyond orphan drug exclusivity,” said Jean-Jacques Bienaime, Chief Executive Officer of BioMarin. “We believe these patents will create significant barriers to therapeutically equivalent generic competition prior to their expiration.”
KuvanÃ‚® (sapropterin dihydrochloride) Tablets are indicated in the United States to reduce blood phenylalanine (Phe) levels in patients with hyperphenylalaninemia (HPA) due to tetrahydrobiopterin- (BH4-) responsive phenylketonuria (PKU). Kuvan is to be used in conjunction with a Phe-restricted diet. 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.
Kuvan has received orphan drug designation from both the U.S. Food and Drug Administration (FDA) and the European Medicines Agency (EMEA). Kuvan has received seven years of orphan exclusivity in the United States and ten years of market exclusivity in the E.U.
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 is required for the metabolism of phenylalanine, 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.
