Eliglustat (Cerdelga) is a glucosylceramide synthase inhibitor that received its first approval in the United States in 2014. As a targeted therapy for Type 1 Gaucher disease, it acts as a substrate reduction therapy by decreasing the production of glucosylceramide (GL-1).
What Kind of Drug Is Eliglustat (Cerdelga)?
Indication Scope
Eliglustat is indicated for the long-term treatment of adult patients with Type 1 Gaucher disease (GD1).
However, these patients must be confirmed as CYP2D6 extensive metabolizers (EMs), intermediate metabolizers (IMs), or poor metabolizers (PMs) through FDA-approved testing.
Pharmacological Action
Gaucher disease is caused by a deficiency of the lysosomal enzyme acid β-glucosidase.
Eliglustat specifically inhibits glucosylceramide synthase (IC50 = 10 ng/mL), reducing the production of GL-1 and thereby alleviating the accumulation of GL-1 in target organs.
By lowering GL-1 production, eliglustat can relieve the accumulation of Gaucher cells in the liver, spleen, and bone marrow, and improve symptoms of organ enlargement and bone disease.
Use Restrictions
CYP2D6 ultrarapid metabolizers may not achieve sufficient eliglustat concentrations to produce therapeutic effects.
For patients with undetermined CYP2D6 genotype (indeterminate metabolizers), a specific dosage cannot be recommended.
