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

Moderate or severe hepatic impairment
Mild hepatic impairment and taking a strong or
moderate CYP2D6 inhibitor
IMs
Taking
a strong CYP3A inhibitor
PMs

Warnings and Precautions
Additions and/or revisions underlined:
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.
Use
of CERDELGA in patients with pre-existing cardiac conditions has not been
studied during clinical trials. Avoid
use of CERDELGA in patients with:

Adverse Reactions
6.1 Clinical Trials Experience
Additions and/or revisions underlined:
The adverse
reaction profile of CERDELGA is based on two controlled studies, Trials 1 and
2. Table 3 presents the profile from the 9-month double-blind, randomized,
placebo-controlled trial of 40 treatment-naive patients (Trial 1).

Drug Interactions
Additions and/or revisions underlined:
7.1 Effect on 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.
Strong CYP3A
inducers decreases eliglustat concentrations which may reduce CERDELGA efficacy.
See Table 5 for
prevention and management of interactions with drugs affecting CERDELGA. Use of
CERDELGA is
contraindicated, to be avoided, or may require dosage adjustment
depending on the concomitant drug and CYP2D6 metabolizer status.

Use in Specific Populations
8.1 Pregnancy
PLLR conversion, additions and/or revisions
underlined:
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.
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 …

8.2 Lactation
PLLR conversion, additions and/or revisions
underlined:
Risk Summary
There are no human
data available on the presence of eliglustat in human milk, the effects on the
breastfed infant, or the effects on milk production. Eliglustat and its
metabolites were present in the milk of lactating rats (see Data). When a drug is present in animal milk, it is likely
that the drug will be present in human milk. The developmental and health
benefits of breastfeeding should be considered along with the mother’s clinical
need for CERDELGA and any potential adverse effects on the breastfed child from
CERDELGA or from the underlying maternal condition.
Data
In a milk
excretion study in the rat, a single oral dose of 30 mg/kg [14C]-labeled eliglustat
was administered to lactating female rats at day 11 postpartum. Approximately
0.23% of the administered radioactivity was excreted into the milk within 24
hours of dose administration. The concentration in the milk at 24 hours post
dose was 16.3-fold higher than the plasma concentration.
8.6 Renal Impairment
Additions and/or revisions underlined:
Use CERDELGA in
patients with renal impairment based on the patient’s CYP2D6 metabolizer status.
EMs
Avoid CERDELGA in patients with end-stage renal
disease (ESRD) (estimated creatinine clearance (eCLcr) less than 15 mL/min
not on dialysis or requiring dialysis).
No dosage adjustment is recommended in
patients with mild, moderate, or severe renal impairment (eCLcr at least 15
mL/min).

8.7 Hepatic Impairment
Additions and/or revisions underlined:

concomitant use of CYP2D6 or CYP3A inhibitors
