- •Diagnosis: Confirmed clinical and biochemical PKU. In addition to the above diagnosis, the inclusion criteria to be satisfied for enrolment in this study are as follows: 1. Male or female PKU infants and young children <4 years of age at the scheduled Day 1 visit of the 26-week Study Period (taking into consideration the maximum of 21 days in the Screening Period). 2. At least two previous blood Phe levels âÂ?Â¥ 400 Ã?¼mol/L obtained on 2 separate occasions. 3. Previously responded, as assessed by the Investigator, to a BH4 test, if all 3 of the following criteria are satisfied: a. The BH4 dose was 20 mg/kg/day; b. The duration of the test was at least for 24 hours; and c. Blood Phe levels decreased by at least 30%. NOTE: If a patient has not undergone a BH4 test prior to Screening, such a test must be performed during Screening, and all 3 of the above criteria must be satisfied for the subject to be eligible for entry into this study. 4. Defined level of dietary Phe tolerance consistent with the diagnosis of PKU; 5. Good adherence to dietary treatment, including prescribed dietary Phe restriction and prescribed amounts of Phe-free protein supplements and low- Phe foods. 6. Maintenance of blood Phe levels within the therapeutic target range of 120-360 Ã?¼mol/L (defined as âÂ?Â¥120 to <360 Ã?¼mol/L) over a 1-month period prior to Screening, as assessed by the Investigator. 7. Parent(s) and/or guardian(s) willing to comply with all study procedures, maintain strict adherence to the diet, and willing and able to provide written, signed informed consent after the nature of the study has been explained and prior to any study procedures.
