Groups2
Neither group, or both, names a comparator, so the groups keep ClinicalTrials.gov's order.
| Group | Title | Description | With the outcome | Analysed | ClinicalTrials.gov code |
|---|---|---|---|---|---|
| Group 1 | Cohort 1 | This cohort will be enrolled first. Analysis will be done to determine the optimum dosing of Kuvan to normalize BH4 levels in the Cerebral Spinal Fluid.~Sapropterin: Sapropterin will be taken daily for 12 or 24 weeks. Starting dose will be 20mg/kg/day and will increase at the 8 week visit to 30 mg/kg/day. Dosing may be further increased to as high as 40 mg/kg/day in attempt to normalize BH4 levels in CSF. Starting dose for Cohort 2 will be determined from data analysis in Cohort 1. | 1 | 6 | EG000 |
| Group 2 | Cohort 2 | Participants in cohort 2 will be enrolled after the analysis of cohort 1 data has taken place. Dosing for cohort 2 will be based on results obtained in cohort 1.~Sapropterin: Sapropterin will be taken daily for 12 or 24 weeks. Starting dose will be 20mg/kg/day and will increase at the 8 week visit to 30 mg/kg/day. Dosing may be further increased to as high as 40 mg/kg/day in attempt to normalize BH4 levels in CSF. Starting dose for Cohort 2 will be determined from data analysis in Cohort 1. | 0 | 6 | EG001 |
