is indicated for the long-term treatment of adult patients with Gaucher disease type 1 (GD1) who are CYP2D6 extensive metabolizers (EMs), intermediate metabolizers (IMs), or poor metabolizers (PMs) as detected by an FDA-cleared test [see Dosage and Administration (2.1) ] . CERDELGA is a glucosylceramide synthase inhibitor indicated for the long-term treatment of adult patients with Gaucher disease type 1 who are CYP2D6 extensive metabolizers (EMs), intermediate metabolizers (IMs), or poor metabolizers (PMs) as detected by an FDA-cleared test. ( 1 ) Limitations of Use : CYP2D6 ultra-rapid metabolizers may not achieve adequate concentrations of CERDELGA to achieve a therapeutic effect. ( 1 ) A specific dosage cannot be recommended for CYP2D6 indeterminate metabolizers. ( 1 ) Limitations of Use : Patients who are CYP2D6 ultra-rapid metabolizers (URMs) may not achieve adequate concentrations of CERDELGA to achieve a therapeutic effect [see Clinical Studies (14) ] . A specific dosage cannot be recommended for those patients whose CYP2D6 genotype cannot be determined (indeterminate metabolizers) [see Clinical Studies (14) ] .

is contraindicated in the following patients based on CYP2D6 metabolizer status due to the risk of cardiac arrhythmias from prolongation of the PR, QTc, and/or QRS cardiac intervals. EMs Taking a strong or moderate CYP2D6 inhibitor concomitantly with a strong or moderate CYP3A inhibitor. ( 4 , 5.1 , 7.1 , 12.3 ) Moderate or severe hepatic impairment. ( 4 , 5.1 , 8.7 , 12.3 ) Mild hepatic impairment taking a strong or moderate CYP2D6 inhibitor. ( 4 , 5.1 , 8.7 , 12.3 ) IMs Taking a strong or moderate CYP2D6 inhibitor concomitantly with a strong or moderate CYP3A inhibitor. ( 4 , 5.1 , 7.1 , 12.3 ) Taking a strong CYP3A inhibitor. ( 4 , 5.1 , 7.1 , 12.3 ) Any degree of hepatic impairment. ( 4 , 5.1 , 8.7 , 12.3 ) PMs Taking a strong CYP3A inhibitor ( 4 , 5.1 , 7.1 , 12.3 ) Any degree of hepatic impairment ( 4 , 5.1 , 8.7 , 12.3 ) EMs Taking a strong or moderate CYP2D6 inhibitor concomitantly with a strong or moderate CYP3A inhibitor [see Drug Interactions (7.1) ] Moderate or severe …

Changes and Potential for Cardiac Arrhythmias : Not recommended in patients with pre-existing cardiac disease, long QT syndrome, and concomitant use of Class IA and Class III antiarrhythmics. ( 5.1 ) 5.1 ECG Changes and Potential for Cardiac Arrhythmias CERDELGA is predicted to cause increases in ECG intervals (PR, QTc, and QRS) at substantially elevated eliglustat plasma concentrations and may increase the risk of cardiac arrhythmias. Use of CERDELGA is contraindicated, to be avoided, or requires dosage adjustment in patients taking CYP2D6 or CYP3A inhibitors, depending on CYP2D6 metabolizer status, type of inhibitor, or degree of hepatic impairment [see Dosage and Administration (2.3) , Contraindications (4) , Drug Interactions (7.1) ] . Use of CERDELGA in patients with pre-existing cardiac conditions has not been studied during clinical trials. Avoid use of CERDELGA in patients with: pre-existing cardiac disease (congestive heart failure, recent acute myocardial infarction, bradycardia, heart block, ventricular arrhythmia) long QT syndrome in combination with Class IA (e.g., quinidine, procainamide) or Class III (e.g., amiodarone, sotalol) antiarrhythmic medications [see Clinical Pharmacology (12.2) ]

8.1 Pregnancy Risk Summary Available data on CERDELGA use in pregnant women includes 20 pregnancies that occurred during the clinical development program and a small number of post-marketing case reports. These data are not sufficient to assess drug-associated risks major birth defects, miscarriage, or adverse maternal or fetal outcomes. In animal reproduction studies in pregnant rats administered oral eliglustat during organogenesis, a spectrum of various developmental abnormalities were observed at doses 6 times the recommended human dose. No adverse developmental outcomes were observed with oral administration of eliglustat to pregnant rabbits at dose levels 10 times the recommended …
