Merck Announces Positive Outcome of IIIb Study for Kuvan (y 2)

Kuvan(R) (sapropterin dihydrochloride) is an oral therapy and the first treatment indicated in Europe in conjuction with a Phe-restricted diet, for the treatment of hyperphenylalaninemia (HPA) due to phenylketonuria (PKU) in patients from the age of 4 who have shown to be responsive to Kuvan, or due to tetrahydrobiopterin (BH4) deficiency. Kuvan was developed jointly by BioMarin Pharmaceutical Inc. and Merck Serono. In the US, Kuvan is marketed by BioMarin and is indicated for the treatment of HPA due to PKU without age restriction. The current label states that safety and efficacy of Kuvan in pediatric patients less than 4 years of age have not been established in clinical studies. Kuvan is to be used in conjunction with a Phe-restricted diet.

Kuvan is the synthetic form of 6R-BH4, a naturally occurring co-factor that works in conjunction with the enzyme phenylalanine hydroxylase (PAH) to metabolize phenylalanine (Phe) into tyrosine. Clinical data show that Kuvan produces significant reductions in blood Phe concentration in a large subset of patients.

Most common side effects reported with the use of Kuvan include headache, runny nose, diarrhea, vomiting, sore throat, cough, abdominal pain, stuffy nose and low levels of phenylalanine in the blood.

Kuvan is approved in 49 countries worldwide, including member states of the European Union and the USA. Under the terms of the agreement with BioMarin, Merck Serono has exclusive rights to market Kuvan in all territories outside the USA, Canada and Japan.
