Summary
This Phase 4 study will evaluate the safety and tolerability of Fabrazyme at current approved dose with increases in the infusion rate and reduced infusion volume. This study aims to generate data to provide the guidance on how infusion rate can be safely increased and minimize the burden of the life-long treatment with Fabrazyme.
Eligibility Criteria
Inclusion Criteria
- Participants with confirmed diagnosis of FD who are ≥2 and ≤65 years of age at the time of signing the informed consent form (ICF) or assent, if applicable.
- Cohort 1: female participants with body weight ≥30 kg who have been treated with Fabrazyme for at least 3 months without IARs during the most recent 3 infusions.
- Cohort 2: non-classic male participants with body weight ≥30 kg who have been treated with Fabrazyme for at least 3 months without IARs during the most recent 3 infusions.
- Cohort 3: classic male participants with body weight ≥30 kg who have been treated with Fabrazyme for at least 3 months without IARs during the most recent 3 infusions.
- Cohort 4: participants with body weight <30 kg who have been treated with Fabrazyme for at least 3 months without IARs during the most recent 3 infusions.
Women of childbearing potential must use a highly effective method of contraception through the study.
Exclusion Criteria
- Female participants who are pregnant or breastfeeding.
- History of significant allergic disease or hypersensitivity to Fabrazyme or other medicinal products.
- Contraindication to Fabrazyme or any of the premedications or rescue medications (diphenhydramine, loratadine, cetirizine, fexofenadine, acetaminophen, montelukast, dexamethasone).
- Any other medical condition considered to make the increased infusion rate not tolerable at the Investigator's discretion.
