Galafold

Approved 10 Aug 2018OralCapsule

Indications

GALAFOLD is indicated for the treatment of adults with a confirmed diagnosis of Fabry disease and an amenable galactosidase alpha gene ( GLA ) variant based on in vitro assay data [see Dosage and Administration (2.1) and Clinical Pharmacology (12.1) ] . This indication is approved under accelerated approval based on reduction in kidney interstitial capillary cell globotriaosylceramide (KIC GL-3) substrate [see Clinical Studies (14) ] .

Continued approval for this indication may be contingent upon verification and description of clinical benefit in confirmatory trials. GALAFOLD is an alpha-galactosidase A (alpha-Gal A) pharmacological chaperone indicated for the treatment of adults with a confirmed diagnosis of Fabry disease and an amenable galactosidase alpha gene ( GLA ) variant based on in vitro assay data. ( 1 , 12.1 ) This indication is approved under accelerated approval based on reduction in kidney interstitial capillary cell globotriaosylceramide (KIC GL-3) substrate.

Continued approval for this indication may be contingent upon verification and description of clinical benefit in confirmatory trials. ( 1 )

Contraindications

None. None. ( 4 )

Interactions

See Full Prescribing Information for clinically significant drug interactions. (7.1)

7.1Effect of Other Drugs on

GALAFOLD Co-administration of GALAFOLD with caffeine decreases migalastat AUC and C max [see Clinical Pharmacology (12.3) ] which may reduce GALAFOLD efficacy. Avoid co-administration of GALAFOLD with caffeine at least 2 hours before and 2 hours after taking GALAFOLD [see Dosage and Administration (2.2) ] .

Pregnancy and breastfeeding

8.1Pregnancy Risk Summary

There were three pregnant women with Fabry disease exposed to GALAFOLD in clinical trials. As such, the available data are not sufficient to assess drug associated risks of major birth defects, miscarriage, or adverse maternal or fetal outcomes. In animal reproduction studies, no adverse developmental effects were observed (see Data ) . The background risk for major birth defects and miscarriage for the indicated population is unknown.

6.1Clinical 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. In clinical trials, 139 patients with Fabry disease (79 females, 60 males, 92% Caucasian, ages 16 to 72 years), who were naïve to GALAFOLD or previously treated with enzyme replacement therapy, were exposed to at least one dose of GALAFOLD.

Of the 139 patients, 127 patients were exposed to GALAFOLD 123 mg every other day for 6 months and 123 patients were exposed for greater than one year. The clinical trials included one randomized, double-blind, placebo-controlled clinical trial of 6 months duration followed by a 6-month open-label treatment phase (Study 1) [see Clinical Studies (14) ] . A second trial was a randomized, open-label, active-controlled clinical trial of 18 months duration in patients with Fabry disease receiving enzyme replacement therapy who were randomized to either switch to GALAFOLD or continue enzyme replacement therapy (Study 2; NCT01218659).

In addition, there were two open-label, long-term extension trials. The most common adverse reactions reported with GALAFOLD (≥ 10%) during the 6-month placebo-controlled, double-blind phase of Study 1 were headache, nasopharyngitis, urinary tract infection, nausea, and pyrexia. Table 1 shows adverse reactions that occurred in at least 5% of patients treated with GALAFOLD during the 6-month placebo-controlled, double-blind phase of Study 1.

6.2Postmarketing Experience

The following adverse reaction has been identified during post-approval use of GALAFOLD. Because this reaction is reported voluntarily from a population of uncertain size, it is not always possible to reliably estimate its frequency or establish a causal relationship to drug exposure.
