competitive inhibitor of CYP2D6 and a strong competitive inhibitor of CYP3A4 and for
whom no reasonable alternative medication exists. or

- The participant was a CYP2D6 poor metabolizer or an indeterminate metabolizer with
neither allele known to be active who was chronically receiving a strong competitive
inhibitor of CYP3A4 and for whom no reasonable alternative medication exists.

Exception for both cases: Premedications for ERT infusions were allowed up to 7 days prior

Summary
Brief summary
The primary objective of this study was to evaluate the efficacy and safety of once daily
(QD) versus twice daily (BID) dosing of eliglustat tartrate (Genz-112638) in participants
with Gaucher disease type 1 who had demonstrated clinical stability on BID dosing of
eliglustat tartrate (Genz-112638). The secondary objective was to evaluate the
pharmacokinetics (PK) of Genz-99067 when eliglustat tartrate (Genz-112638) was administered
QD and BID in participants with Gaucher disease type 1 who had demonstrated clinical
stability on BID dosing of eliglustat tartrate (Genz-112638).
