Tip the challenges of Phe control in their favor

KUVAN is the first and only prescription medication that lowers blood Phe levels.1 KUVAN is indicated 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.1

In clinical trials:

  • KUVAN, when used along with dietary management, lowered blood Phe levels more than dietary intervention alone in BH4-responsive PKU patients1
  • KUVAN significantly lowered blood Phe levels in BH4-responsive PKU patients who were not following a Phe-restricted diet, regardless of baseline blood Phe levels1
  • KUVAN improved Phe metabolism by stimulating the activity of the PAH enzyme, the core defect in PKU1
  • KUVAN has been shown to be well tolerated at doses from 5 mg/kg/day to
    20 mg/kg/day1

Indication

KUVAN® (sapropterin dihydrochloride) Tablets is indicated 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.

Important Safety Information

Prolonged exposure to elevated blood Phe levels in PKU patients can result in severe neurologic damage. The initiation of KUVAN therapy does not eliminate the need for careful monitoring of blood Phe levels and ongoing dietary management.

Some patients receiving KUVAN can experience significant drops in blood Phe levels. Patients should be monitored closely to ensure that blood Phe levels do not fall too low.

Not all patients with PKU respond to treatment with KUVAN. Response to treatment can only be determined by a therapeutic trial of KUVAN.

KUVAN has not been studied in patients with liver or renal impairment. Patients who have these conditions should be carefully monitored when receiving KUVAN. Caution should be used with the administration of KUVAN to patients who are receiving levodopa and drugs that affect nitric oxide–mediated vasorelaxation or folate metabolism.

The most serious adverse reactions reported during KUVAN administration (regardless of relationship to treatment) were gastritis, spinal cord injury, streptococcal infection, testicular carcinoma, and urinary tract infection. Mild to moderate neutropenia was also noted. The most common adverse reactions were headache, diarrhea, abdominal pain, upper respiratory tract infection, pharyngolaryngeal pain, vomiting, and nausea.
