Description:

11 description migalastat, an alpha-galactosidase a (alpha-gal a) pharmacological chaperone, is a low molecular weight iminosugar and an analogue of the terminal galactose of globotriaosylceramide (gl-3). migalastat is present in the form of a hydrochloride salt in galafold. the chemical name for migalastat hydrochloride is (+)-(2 r ,3 s ,4 r ,5 s )-2-(hydroxymethyl) piperidine-3,4,5-triol hydrochloride. its molecular formula is c 6 h 13 no 4 •hcl, molecular mass is 199.63 g/mol, and its chemical structure is depicted below. migalastat hydrochloride is a white to almost white crystalline solid. it is freely soluble in aqueous media within the ph range of 1.2 to 7.5. galafold (migalastat) capsules for oral administration contain 123 mg of migalastat (equivalent to 150 mg migalastat hydrochloride) as a white to pale brown powder and are supplied in a size “2” hard gelatin capsule with an opaque blue cap and an opaque white body imprinted with “a1001” in black ink. the inactive ingredients are magnesium stearate and pregelatinized starch. capsule shells consist of gelatin, indigotine - fd&c blue 2, and titanium dioxide. the black ink consists of black iron oxide, potassium hydroxide, and shellac. chemical structure

Clinical Pharmacology:

12 clinical pharmacology 12.1 mechanism of action migalastat is a pharmacological chaperone that reversibly binds to the active site of the alpha-galactosidase a (alpha-gal a) protein (encoded by the galactosidase alpha gene, gla ), which is deficient in fabry disease. this binding stabilizes alpha-gal a allowing its trafficking from the endoplasmic reticulum into the lysosome where it exerts its action. in the lysosome, at a lower ph and at a higher concentration of relevant substrates, migalastat dissociates from alpha-gal a allowing it to break down the glycosphingolipids globotriaosylceramide (gl-3) and globotriaosylsphingosine (lyso-gb 3 ). certain gla variants (mutations) causing fabry disease result in the production of abnormally folded and less stable forms of the alpha-gal a protein which, however, retain enzymatic activity. those gla variants, referred to as amenable variants, produce alpha-gal a proteins that may be stabilized by migalastat thereby restoring their trafficki
ng to lysosomes and their intralysosomal activity. in vitro amenability assay in an in vitro assay (hek-293 assay), human embryonic kidney (hek-293) cell lines were transfected with specific gla variants (mutations) which produced mutant alpha-gal a proteins. in the transfected cells, amenability of the gla variants was assessed after a 5-day incubation with 10 micromol/l migalastat. a gla variant was categorized as amenable if the resultant mutant alpha-gal a activity (measured in the cell lysates) met two criteria: 1) it showed a relative increase of at least 20% compared to the pre-treatment alpha-gal a activity, and 2) it showed an absolute increase of at least 3% of the wild-type (normal) alpha-gal a activity. the in vitro assay did not evaluate trafficking of the mutant alpha-gal a proteins into the lysosome or the dissociation of migalastat from the mutant alpha-gal a proteins within the lysosome. also, the in vitro assay did not test whether a gla variant causes fabry disease or not. the gla variants which are amenable to treatment with galafold, based on the in vitro assay data, are shown in table 2 . inclusion of gla variants in this table does not reflect interpretation of their clinical significance in fabry disease. whether a certain amenable gla variant in a patient with fabry disease is disease-causing or not should be determined by the prescribing physician (in consultation with a clinical genetics professional, if needed) prior to treatment initiation. consultation with a clinical genetics professional is strongly recommended in cases where the amenable gla variant is of uncertain clinical significance (vus, variant of uncertain significance) or may be benign (not causing fabry disease). table 2: amenable gla variants based on the in vitro assay * based on available published data, the gla variant c.937g>t, (p.(d313y)) is considered benign (not causing fabry disease). consultation with a clinical genetics professional is strongly recommended in patients with fabry disease who have this gla variant as additional evaluations may be indicated. dna change (long) dna change (short) protein change (1-letter code) protein change

lyso-gb 3 assessments available after 6 months of treatment. the median change from baseline to month 6 in plasma lyso-gb 3 (nmol/l) was -2.37 (range -69.7, 1.8) in patients on galafold and 0.53 (range -21.5, 16.3) in patients on placebo. in the open-label treatment phase of study 1, the 13 patients who were initially on placebo for 6 months and who switched to galafold for another 6 months had a median change in lyso-gb 3 (nmol/l) of -2.72 (range -61.1, -0.3). the 18 patients who were treated with galafold for 6 months and then continued galafold in the open-label treatment phase of study 1 for an additional 6 months had no further changes in plasma lyso-gb 3 . in study 2, 46 of 56 patients with amenable gla variants (31 on galafold, 15 on enzyme replacement therapy (ert)) had lyso-gb 3 assessments available after 18 months of treatment. the median change from baseline to month 18 in plasma lyso-gb 3 (nmol/l) was 0.53 (range -2.27, 28.3) in patients on galafold and -0.03 (range -11.9, 2.57) in patients on ert. cardiac electrophysiology at a dose approximately 8 times the recommended dose, galafold did not prolong the qt interval to any clinically relevant extent. 12.3 pharmacokinetics absorption following a single galafold oral dose of 123 mg, the absolute bioavailability (auc) of migalastat was approximately 75% and the time to peak plasma concentration was approximately 3 hours. plasma migalastat exposure (auc 0-∞ and c max ) demonstrated dose-proportional increases at oral doses from 75 mg to 1250 mg (doses from 0.5 to 8.3-fold of the approved recommended dosage). migalastat does not accumulate following administration of 123 mg galafold every other day. effect of food: administration of galafold one hour before a high-fat (850 calories; 56% from fat) or light meal (507 calories; 30% from fat), or one hour after a light meal, reduced the mean migalastat auc 0-∞ by 37% to 42% and c max by 15% to 39% compared to the fasting state [see dosage and administration ( 2.2 )] . effect of beverages: a single-dose, 6-way crossover pharmacokinetic study was conducted in 20 healthy subjects to evaluate plasma migalastat bioavailability of a 150 mg migalastat hcl capsule when administered with coffee and sweetened beverages relative to administration with water. the rate of absorption (t max ) of migalastat was not affected by administration of coffee or sweetened beverages in comparison to water. consumption of 280 ml of coffee containing approximately 190 mg caffeine at the time of dosing resulted in significant decrease in migalastat systemic exposure (mean reduction in auc 0-∞ by 57% and mean reduction in c max by 60%) when compared to water. the bioavailability of migalastat did not appreciably differ when administered with natural (sucrose: 8027 ng·h/ml auc 0-∞ and 1265 ng/ml c max ) and artificial (aspartame or acesulfame k: 9075 ng·h/ml, 8641 ng·h/ml auc 0-∞ and 1374 ng/ml, 1225 ng/ml c max respectively) sweeteners when compared to water (8613 ng·h/ml auc 0-∞ and 1328 ng/ml c max ) [see dosage and administration ( 2.2 )] . distribution the apparent volume of distribution (v z /f) of migalastat in fabry patients was approximately 89 l (range: 77 to 133 l) at steady state. there was no detectable plasma protein binding following administration of [ 14 c]-migalastat in the concentration range between 1 to 100 microm. elimination metabolism: based upon in vivo data, migalastat is a substrate for uridine diphosphate glucuronosyltransferase (udpgt), a minor elimination pathway. excretion: in a mass balance study in healthy male subjects, following oral administration of 123 mg [ 14 c]-migalastat, approximately 77% of the total radiolabeled dose was recovered in urine and 20% of the total radiolabeled dose was recovered in feces with an overall total recovery of 98% within 96 hours post-dose. in urine, unchanged migalastat accounted for 80% of the radioactivity, which equates to 62% of the administered dose. in feces, unchanged migalastat was the only drug-related component. in plasma, unchanged migalastat accounted for approximately 77% of the plasma radioactivity and three dehydrogenated o-glucuronide conjugated metabolites, m1 to m3, together accounted for approximately 13% of the plasma radioactivity, none of which comprised more than 6% of the radiolabeled dose. approximately 9% of the total radioactivity in plasma was unassigned. following a single oral dose of 123 mg galafold, migalastat is cleared from plasma with a mean half-life (t ½ ) of approximately 4 hours and apparent clearance of 12.5 l/hr. specific populations male and female patients: the pharmacokinetic characteristics of migalastat were not significantly different between healthy male and female subjects or patients with fabry disease. racial or ethnic groups: clinical data indicate no ethnic differences in patient populations studied with migalastat. patients with renal impairment: in a single-dose study in subjects with varying degrees of renal impairment, exposure to migalastat (auc) was increased by 1.2-, 1.8-, and 4.3-fold in subjects with mild (egfr 60 to 90 ml/min/1.73 m 2 ), moderate (egfr 30 to 59 ml/min/1.73 m 2 ), and severe renal impairment (egfr less than 30 ml/min/1.73 m 2 ), respectively, while the c max remained unchanged with severity of renal impairment [see use in specific populations ( 8.6 )] . drug interaction studies migalastat is not a known inhibitor or inducer of cytochrome p450 (cyp450) enzymes, nor is it an inhibitor of bcrp, mdr1, p-glycoprotein (p-gp), or bsep human efflux transporters, or oatp1b1, oatp1b3, oat1, oat3, oct1, oct2, mate1, or mate2-k human uptake transporters. migalastat is not a substrate of p-gp, bcrp, mdr1 or mate1, mate2-k, oat1, oat3, or oct2. migalastat showed low affinity for sglt1, as both a substrate and an inhibitor, and showed no activity for sglt2.

Mechanism of Action:

12.1 mechanism of action migalastat is a pharmacological chaperone that reversibly binds to the active site of the alpha-galactosidase a (alpha-gal a) protein (encoded by the galactosidase alpha gene, gla ), which is deficient in fabry disease. this binding stabilizes alpha-gal a allowing its trafficking from the endoplasmic reticulum into the lysosome where it exerts its action. in the lysosome, at a lower ph and at a higher concentration of relevant substrates, migalastat dissociates from alpha-gal a allowing it to break down the glycosphingolipids globotriaosylceramide (gl-3) and globotriaosylsphingosine (lyso-gb 3 ). certain gla variants (mutations) causing fabry disease result in the production of abnormally folded and less stable forms of the alpha-gal a protein which, however, retain enzymatic activity. those gla variants, referred to as amenable variants, produce alpha-gal a proteins that may be stabilized by migalastat thereby restoring their trafficking to lysosomes and their intralysosomal activity. in vitro amenability assay in an in vitro assay (hek-293 assay), human embryonic kidney (hek-293) cell lines were transfected with specific gla variants (mutations) which produced mutant alpha-gal a proteins. in the transfected cells, amenability of the gla variants was assessed after a 5-day incubation with 10 micromol/l migalastat. a gla variant was categorized as amenable if the resultant mutant alpha-gal a activity (measured in the cell lysates) met two criteria: 1) it showed a relative increase of at least 20% compared to the pre-treatment alpha-gal a activity, and 2) it showed an absolute increase of at least 3% of the wild-type (normal) alpha-gal a activity. the in vitro assay did not evaluate trafficking of the mutant alpha-gal a proteins into the lysosome or the dissociation of migalastat from the mutant alpha-gal a proteins within the lysosome. also, the in vitro assay did not test whether a gla variant causes fabry disease or not. the gla variants which are amenable to treatment with galafold, based on the in vitro assay data, are shown in table 2 . inclusion of gla variants in this table does not reflect interpretation of their clinical significance in fabry disease. whether a certain amenable gla variant in a patient with fabry disease is disease-causing or not should be determined by the prescribing physician (in consultation with a clinical genetics professional, if needed) prior to treatment initiation. consultation with a clinical genetics professional is strongly recommended in cases where the amenable gla variant is of uncertain clinical significance (vus, variant of uncertain significance) or may be benign (not causing fabry disease). table 2: amenable gla variants based on the in vitro assay * based on available published data, the gla variant c.937g>t, (p.(d313y)) is considered benign (not causing fabry disease). consultation with a clinical genetics professional is strongly recommended in patients with fabry disease who have this gla variant as additional evaluations may be indicated. dna change (long) dna change (short) protein change (1-letter code) protein change (3-letter code) c.7c>g c.c7g p.(l3v) p.(leu3val) c.8t>c c.t8c p.(l3p) p.(leu3pro) c.[11g>t;

Pharmacodynamics:

12.2 pharmacodynamics in study 1, 31 of 50 patients with amenable gla variants (18 on galafold, 13 on placebo) had lyso-gb 3 assessments available after 6 months of treatment. the median change from baseline to month 6 in plasma lyso-gb 3 (nmol/l) was -2.37 (range -69.7, 1.8) in patients on galafold and 0.53 (range -21.5, 16.3) in patients on placebo. in the open-label treatment phase of study 1, the 13 patients who were initially on placebo for 6 months and who switched to galafold for another 6 months had a median change in lyso-gb 3 (nmol/l) of -2.72 (range -61.1, -0.3). the 18 patients who were treated with galafold for 6 months and then continued galafold in the open-label treatment phase of study 1 for an additional 6 months had no further changes in plasma lyso-gb 3 . in study 2, 46 of 56 patients with amenable gla variants (31 on galafold, 15 on enzyme replacement therapy (ert)) had lyso-gb 3 assessments available after 18 months of treatment. the median change from baseline to month 18 in plasma lyso-gb 3 (nmol/l) was 0.53 (range -2.27, 28.3) in patients on galafold and -0.03 (range -11.9, 2.57) in patients on ert. cardiac electrophysiology at a dose approximately 8 times the recommended dose, galafold did not prolong the qt interval to any clinically relevant extent.

Pharmacokinetics:

12.3 pharmacokinetics absorption following a single galafold oral dose of 123 mg, the absolute bioavailability (auc) of migalastat was approximately 75% and the time to peak plasma concentration was approximately 3 hours. plasma migalastat exposure (auc 0-∞ and c max ) demonstrated dose-proportional increases at oral doses from 75 mg to 1250 mg (doses from 0.5 to 8.3-fold of the approved recommended dosage). migalastat does not accumulate following administration of 123 mg galafold every other day. effect of food: administration of galafold one hour before a high-fat (850 calories; 56% from fat) or light meal (507 calories; 30% from fat), or one hour after a light meal, reduced the mean migalastat auc 0-∞ by 37% to 42% and c max by 15% to 39% compared to the fasting state [see dosage and administration ( 2.2 )] . effect of beverages: a single-dose, 6-way crossover pharmacokinetic study was conducted in 20 healthy subjects to evaluate plasma migalastat bioavailability of a 150
mg migalastat hcl capsule when administered with coffee and sweetened beverages relative to administration with water. the rate of absorption (t max ) of migalastat was not affected by administration of coffee or sweetened beverages in comparison to water. consumption of 280 ml of coffee containing approximately 190 mg caffeine at the time of dosing resulted in significant decrease in migalastat systemic exposure (mean reduction in auc 0-∞ by 57% and mean reduction in c max by 60%) when compared to water. the bioavailability of migalastat did not appreciably differ when administered with natural (sucrose: 8027 ng·h/ml auc 0-∞ and 1265 ng/ml c max ) and artificial (aspartame or acesulfame k: 9075 ng·h/ml, 8641 ng·h/ml auc 0-∞ and 1374 ng/ml, 1225 ng/ml c max respectively) sweeteners when compared to water (8613 ng·h/ml auc 0-∞ and 1328 ng/ml c max ) [see dosage and administration ( 2.2 )] . distribution the apparent volume of distribution (v z /f) of migalastat in fabry patients was approximately 89 l (range: 77 to 133 l) at steady state. there was no detectable plasma protein binding following administration of [ 14 c]-migalastat in the concentration range between 1 to 100 microm. elimination metabolism: based upon in vivo data, migalastat is a substrate for uridine diphosphate glucuronosyltransferase (udpgt), a minor elimination pathway. excretion: in a mass balance study in healthy male subjects, following oral administration of 123 mg [ 14 c]-migalastat, approximately 77% of the total radiolabeled dose was recovered in urine and 20% of the total radiolabeled dose was recovered in feces with an overall total recovery of 98% within 96 hours post-dose. in urine, unchanged migalastat accounted for 80% of the radioactivity, which equates to 62% of the administered dose. in feces, unchanged migalastat was the only drug-related component. in plasma, unchanged migalastat accounted for approximately 77% of the plasma radioactivity and three dehydrogenated o-glucuronide conjugated metabolites, m1 to m3, together accounted for approximately 13% of the plasma radioactivity, none of which comprised more than 6% of the radiolabeled dose. approximately 9% of the total radioactivity in plasma was unassigned. following a single oral dose of 123 mg galafold, migalastat is cleared from plasma with a mean half-life (t ½ ) of approximately 4 hours and apparent clearance of 12.5 l/hr. specific populations male and female patients: the pharmacokinetic characteristics of migalastat were not significantly different between healthy male and female subjects or patients with fabry disease. racial or ethnic groups: clinical data indicate no ethnic differences in patient populations studied with migalastat. patients with renal impairment: in a single-dose study in subjects with varying degrees of renal impairment, exposure to migalastat (auc) was increased by 1.2-, 1.8-, and 4.3-fold in subjects with mild (egfr 60 to 90 ml/min/1.73 m 2 ), moderate (egfr 30 to 59 ml/min/1.73 m 2 ), and severe renal impairment (egfr less than 30 ml/min/1.73 m 2 ), respectively, while the c max remained unchanged with severity of renal impairment [see use in specific populations ( 8.6 )] . drug interaction studies migalastat is not a known inhibitor or inducer of cytochrome p450 (cyp450) enzymes, nor is it an inhibitor of bcrp, mdr1, p-glycoprotein (p-gp), or bsep human efflux transporters, or oatp1b1, oatp1b3, oat1, oat3, oct1, oct2, mate1, or mate2-k human uptake transporters. migalastat is not a substrate of p-gp, bcrp, mdr1 or mate1, mate2-k, oat1, oat3, or oct2. migalastat showed low affinity for sglt1, as both a substrate and an inhibitor, and showed no activity for sglt2.

Nonclinical Toxicology:

13 nonclinical toxicology 13.1 carcinogenesis, mutagenesis, impairment of fertility carcinogenesis the carcinogenic potential of migalastat was assessed in a 2-year study in rats and a 26-week study in tg.rash2 mice. in the 2-year rat study, migalastat was not tumorigenic at oral doses of up to 600 mg/kg twice daily (24 times the recommended dose based on auc). in the 26-week study in tg.rash2 mice, migalastat was not tumorigenic at oral doses of up to 1000 mg/kg/day in males and 500 mg/kg/day in females. mutagenesis migalastat was negative in the bacterial mutagenicity (ames) assay, in vitro cell mutation assay in l5178y mouse lymphoma tk +/- cells, and in vivo micronucleus assay in rats. impairment of fertility oral administration of up to 12.5 mg/kg migalastat twice daily in rats (equivalent to the human auc at the recommended dose) produced a significant decrease in male fertility. this effect was completely reversed after four weeks of recovery. female fertility was not affected.
