Kuvan® (sapropterin dihydrochloride) Patient
Julie, an industrial interior designer, has a rare genetic disorder known as PKU (phenylketonuria). She has been on treatment with Kuvan since 2005 when she enrolled in BioMarin’s Phase I clinical trials. “Initially, I enrolled in the Kuvan clinical study to help younger people with PKU have more options,” she says. “I sort of felt it was too late for me. I was 23 then and believed I had pretty good control of my diet and couldn’t do much more than that. But almost immediately I became one of the highest responders in my clinic! Now, a decade later, I feel a major improvement, especially when I train for runs and triathlons, and my Phe levels remain well within the normal range.”
Currently, BioMarin’s second product candidate for PKU, Pegvaliase (also known as PEG PAL) is in human clinical trials. Julie is also looking forward to future advancements in PKU treatment.
“Advancements in the treatment of PKU have made a huge impact in my life in an incredibly short period of time. I’ve had PKU all my life—and the advances made just within the last five years blow the advancements from all the previous years out of the water!”

Your doctor and dietitian will continue to monitor your diet and blood Phe levels throughout your treatment with Kuvan.
If you have a fever, or if you are sick, your Phe level may go up. Tell your doctor and dietitian as soon as possible so they can see if they have to adjust your treatment to help keep your blood Phe levels in the desired range.
