Trial Review

Did you know?

The ANZCTR now automatically displays published trial results and simplifies the addition of trial documents such as unpublished protocols and statistical analysis plans.

These enhancements will offer a more comprehensive view of trials, regardless of whether their results are positive, negative, or inconclusive.

The safety and scientific validity of this study is the responsibility of the study sponsor and investigators. Listing a study does not mean it has been endorsed by the ANZCTR. Before participating in a study, talk to your health care provider and refer to this information for consumers

* The participant was a CYP2D6 non-poor metabolizer or an indeterminate metabolizer with one allele identified as active who was chronically receiving both a strong 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 to the first dose of Genz-112638.

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).
