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 | Tolerance Induction Period (TIP): Cyclosporine A (CsA) starting at 5 milligram per kilogram (mg/kg) orally three times daily until the target trough concentration of at least 350 nanogram per milliliter (ng/mL) (preferably 400 ng/mL) achieved along with azathioprine (Aza) 2.5 mg/kg/day orally. Once target CsA trough level achieved and maintained for at least 1 week, participants received laronidase 0.058 mg/kg (low-dose) once weekly intravenous (IV) infusion (starting from Day 1) up to Week 12. CsA and Aza were gradually discontinued. Immune Challenge Period (ICP): following TIP, laronidase dose increased to 0.12 mg/kg once weekly IV infusion for 1 week followed by 0.25 mg/kg once weekly IV infusion for 1 week and then 0.58 mg/kg (full-dose) once weekly IV infusion up to Week 39. | 2 | 3 | EG000 |
| Group 2 | Cohort 2 | TIP: CsA starting at 6.7 mg/kg orally three times daily until the target trough concentration of at least 350 ng/mL (preferably 400 ng/mL) achieved along with Aza 5 mg/kg orally every other day. Once target CsA trough level achieved and maintained for at least 1 week, participants received laronidase 0.058 mg/kg (low- dose) once weekly IV infusion (starting from Day 1) up to Week 18. CsA and Aza were gradually discontinued. ICP: following TIP, laronidase dose increased to 0.12 mg/kg once weekly IV infusion for 1 week followed by 0.25 mg/kg once weekly IV infusion for 1 week and then 0.58 mg/kg (full-dose) once weekly IV infusion up to Week 45. | 1 | 3 | EG001 |
