Kuvan® (sapropterin dihydrochloride) Patient
Baton Rouge, Louisiana

Lauren - BioMarin Patient StoriesLauren is a bright, energetic young adult with a hectic schedule, big life plans, and a very bright future. She graduated high school as valedictorian and is working toward a bachelor of science degree in chemistry. Since initiating treatment with KUVAN, her Phe levels have decreased significantly.
Because high Phe levels are toxic to the brain, some patients never reach their full intellectual potential and suffer from other related social and neurocognitive problems. Lauren keeps her Phe levels down by taking Kuvan and maintaining her low Phe diet.

“She’s an extremely bright young woman and we want to give her every opportunity to reach her intellectual potential,” says her physician, Dr. Andersson. “Kuvan has been a great opportunity for Lauren to get her Phe levels down significantly lower than they were before.”

Lauren says that now she knows it is possible to have PKU and still live a normal life. “I am living proof,” she says.

“I would like to thank everyone at BioMarin for continuing to work tirelessly to enhance the lives of PKU patients everywhere. I’ve always known that I can do anything while living with PKU, but your hard work has certainly helped me to succeed.”

* Individual patient response to Kuvan® therapy will vary.

Your doctor and dietitian will continue to monitor your diet and blood Phe levels throughout your treatment with Kuvan.
