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 | KRN23 TIO | Participants with TIO received burosumab at a starting dose of 0.3 mg/kg administered subcutaneously (SC) every 4 weeks (Q4W). Doses may have been titrated up to a maximum of 2.0 mg/kg every 2 weeks (Q2W) in order to achieve fasting peak serum phosphorus levels within the target range of 2.5 to 4.0 mg/dL. | 2 | 14 | EG000 |
| Group 2 | KRN23 XLH and ENS | Participants with XLH and ENS received burosumab at a starting dose of 0.3 mg/kg administered subcutaneously (SC) every 4 weeks (Q4W). Doses may have been titrated up to a maximum of 2.0 mg/kg every 2 weeks (Q2W) in order to achieve fasting peak serum phosphorus levels within the target range of 2.5 to 4.0 mg/dL. | 0 | 3 | EG001 |
