Contraindications
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.

Pregnancy & Breastfeeding
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 human dose [see Data ] . The estimated background risk of major birth defects and miscarriage in the indicated population is unknown. All pregnancies have a background risk of birth defect, loss or other adverse outcomes. In the U.S. general population, the estimated background risk of major birth defects and miscarriage in clinically recognized pregnancies is 2% to 4% and 15% to 20%, respectively. Clinical Considerations Disease-associated maternal and/or embryo/fetal risk Women with Gaucher disease type 1 have an increased risk of spontaneous abortion, especially if disease symptoms are not treated and controlled pre-conception and during a pregnancy. Pregnancy may exacerbate existing Gaucher disease type 1 symptoms or result in new disease manifestations. Gaucher disease type 1 manifestations may lead to adverse pregnancy outcomes including, hepatosplenomegaly which can interfere with the normal growth of a pregnancy and thrombocytopenia which can lead to increased bleeding and possible hemorrhage. Data Animal data Reproduction studies have been performed in pregnant rats at oral doses up to 120 mg/kg/day (about 6 times the recommended human dose based on body surface area) and in pregnant rabbits at oral doses up to 100 mg/kg/day (about 10 times the recommended human dose based on

Concomitant use is contraindicated in poor or intermediate CYP2D6 metabolizers and in patients taking CYP2D6 inhibitors due to QT prolongation risk.

Strong CYP3A inhibitors are contraindicated in intermediate and poor CYP2D6 metabolizers due to increased eliglustat concentrations and cardiac arrhythmia risk.

Eliglustat may increase concentrations of P-glycoprotein substrates, increasing toxicity risk. Monitor therapeutic concentrations or reduce dosage as needed.
Source: NLP:eliglustat
Strong CYP3A inducers decrease eliglustat concentrations, which may reduce CERDELGA efficacy. Coadministration should be avoided.

Eliglustat may increase digoxin concentrations as a P-gp substrate. Monitor serum digoxin and reduce dose by 30% before initiating eliglustat.
