Eliglustat
Generic Name: eliglustat
Brand Names:
Cerdelga
11 DESCRIPTION CERDELGA (eliglustat) capsules contain eliglustat tartrate, which is a small molecule inhibitor of glucosylceramide synthase that resembles the ceramide substrate for the enzyme, with the chemical name N-((1 R ,2 R )-1-(2,3-dihydrobenzo[b][1,4]dioxin-6-yl)-1-hydroxy-3-(pyrrolidin-1-yl)propan-2-yl)octanamide (2 R ,3 R )-2,3-dihydroxysuccinate.

Uses
1 INDICATIONS AND USAGE CERDELGA 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.
Dosage
2 DOSAGE AND ADMINISTRATION Patient Selection ( 2.1 ) : Select patients using an FDA-cleared test for determining CYP2D6 genotype. Recommended Dosage Based on CYP2D6 Metabolizer Status ( 2.2 ) : EMs and IMs: 84 mg orally twice daily. PMs: 84 mg orally once daily. See the Full Prescribing Information for dosing recommendations in patients receiving CYP2D6 and/or CYP3A inhibitors, or with renal or hepatic impairment. ( 2.2 , 4 , 7.1 , 8.6 , 8.7 ) Administration ( 2.4 ) : Swallow capsules whole, do not crush, dissolve or open capsules. ( 2.4 ) Avoid eating grapefruit or drinking grapefruit juice. ( 2.4 ) 2.1 Patient Selection Select patients with Gaucher disease type 1 based on their CYP2D6 metabolizer status.
Side Effects
6 ADVERSE REACTIONS Most common adverse reactions (≥10%) are: fatigue, headache, nausea, diarrhea, back pain, pain in extremities, and upper abdominal pain. ( 6.1 ) To report SUSPECTED ADVERSE REACTIONS, contact Genzyme Corporation at 1-800-745-4447 or FDA at 1-800-FDA-1088 or www.fda.gov/medwatch. 6.1 Clinical Trials Experience Because clinical trials are conducted under widely varying conditions, adverse reaction rates observed in the clinical trials of a drug cannot be directly compared to rates in the clinical trials of another drug and may not reflect the rates observed in practice.
Interactions
7 DRUG INTERACTIONS See Full Prescribing Information for a list of clinically significant drug interactions. ( 7.1 , 7.2 ) 7.1 Effect of Other Drugs on CERDELGA Coadministration of CERDELGA with: CYP2D6 or CYP3A inhibitors may increase eliglustat concentrations which may increase the risk of cardiac arrhythmias from prolongation of the PR, QTc, and/or QRS cardiac interval [see Warnings and Precautions (5.1) , Clinical Pharmacology (12.3) ] . strong CYP3A inducers decrease eliglustat concentrations which may reduce CERDELGA efficacy [see Clinical Pharmacology (12.3) ] . See Table 5 for prevention and management of interactions with drugs affecting CERDELGA.
Warnings
5 WARNINGS AND PRECAUTIONS ECG 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) ] . 4 CONTRAINDICATIONS CERDELGA 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.
Pregnancy
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.
Storage
Store at 68°F–77°F (20°C–25°C) with excursions permitted between 59°F and 86°F (15°C to 30°C) [see USP Controlled Room Temperature].
