Liam

Age 11
Kuvan® Patient

"We were a very unhappy family much of the time before we were able to control Liam's Phe levels," recalls his mother, Rosie. "Life revolved around him, his formula, and his food. There was no balance in our home because we were focused on trying to control his Phe. He was unhappy and struggling, so we were unhappy and struggling."

Happiest when he's playing soccer, Legos, or with his dog Finn, Liam says he's got huge plans for the future. "I want to be an oceanographer like Robert Ballard and raise the Titanic. I'll make a movie and probably hire Harrison Ford for the leading role."

Dynamics at home are much different today, however.

"We continue to weigh all of Liam's food and he still maintains a low protein diet, but now with Kuvan he feels like he has added help in his battle to manage his Phe," mom elaborates.

Liam is a sixth-grader who has been on Kuvan therapy since December 2007. "My life is pretty good now that my Phe levels are lower," he reports. "When I started, I made a contract with my nutritionist to take Kuvan with breakfast in the morning. It didn't work out a few times but then it worked out when I changed the time I took my pills. Now I take it after dinner so I don't forget during the morning rush."

Liam's doctor has prescribed 7 Kuvan Tablets a day, dissolved in water. Before starting therapy, Liam's blood Phe levels peaked at 7 mg/dL, but today, by both maintaining a low-Phe diet and taking his daily dose of Kuvan, he's holding steady at about 4 mg/dL.*

"Before Kuvan, I understood my diet, but I didn't really cooperate because I didn't like food being taken away. I would feel angry and sad because I couldn't have any foods I like," he recalls. "I'm still eating the same food as before, but since I started taking Kuvan, I've been more cooperative because I feel good that my Phe is lower," he continues; "basically I am a success story."

"I think Liam is happier now," recalls his ten-year-old sister, Catriona. "He is eating better and does more activities outside.

Now, with Phe levels under control, mom reports that Liam has been more compliant and is better able to "deal" with his low-protein PKU diet.

"In the days before Kuvan, Liam had a can-do attitude in all areas of life except his diet. Now that attitude is applied to dietary compliance and managing his Phe levels," she says. He's more compliant with his diet and he's taking his vitamin supplements and medical formula. Now he's easily getting about 60 grams of protein each day from formula, while in the past, every ounce was a struggle," she adds.

"He still eats the same low-protein PKU foods, like rice and spaghetti, but now he can also eat some foods with more natural protein."

Occasionally, Liam can even enjoy a small portion of his favorite food, fava beans.

"Go figure!" mom says, reflecting on his unusual preference for this healthy food.

"I am delighted that Liam's Phe levels are better now," she adds, "and most days are good.—Days when I know Liam has had enough Phe, protein and calories and we can all go to bed satisfied."
