ClinicalTrials.gov Identifier:
NCT00841100
First received: February 10, 2009
Last updated: March 10, 2009
Last verified: February 2009
  Purpose

The investigators will investigate the effect of blood phenylalanine on Kuvan responsiveness in the same patients with PKU when their blood phenylalanine concentrations are altered by diet.

Lowering blood phenylalanine concentrations in Kuvan non-responsive patients with PKU will increase the frequency of Kuvan responsiveness.
