Drug interaction overview
- Berotralstat is a P-gp and BCRP substrate, a P-gp inhibitor, a moderate CYP2D6 inhibitor, and weak CYP2D6 and CYP2C19 inhibitor
-
P-gp or BCRP inhibitors
- Reduce berotralstat dose when coadministered
- Cyclosporine, a P-gp and BCRP inhibitor, increased berotralstat peak plasma concentration by 25%, AUC(0-last) by 55%, and AUC(0-inf) by 69%
-
P-gp inducers
- Avoid coadministration
- P-gp inducers (eg, rifampin, St. John’s wort) may decrease berotralstat plasma concentration and efficacy
-
CYP2D6 or CYP3A4
- Monitor or titrate substrate dose when coadministered with narrow therapeutic index drugs that are CYP2D6 or CYP3A substrates
- Berotralstat moderately inhibits CYP2D6 or CYP3A4 at recommended dose (ie, 150 mg)
-
P-gp substrates
- Monitoring or dose titration is recommended for P-gp substrates (eg, digoxin)
- Berotralstat inhibits P-gp at higher than recommended dose (ie, 300 mg)
Pregnancy & Lactation
Pregnancy
Insufficient data available regarding use in pregnant females to inform drug-associated risks
Animal data
- No structural alterations observed when orally administered to pregnant rats and rabbits during organogenesis at doses up to ~10 and 2x, respectively, the maximum recommended human daily dose in adults based on AUC
Lactation
There are no data on drug presence in human milk, effects on breastfed infants, or effects on milk production
Low levels of berotralstat detected in plasma of rat pups when oral administered to dams during lactation period; berotralstat concentration in pup plasma was ~2% of maternal plasma
When drug is present in animal milk, it is likely the drug will be present in human milk
Pregnancy Categories
A: Generally acceptable. Controlled studies in pregnant women show no evidence of fetal risk.
B: May be acceptable. Either animal studies show no risk but human studies not available or animal studies showed minor risks and human studies done and showed no risk. C: Use with caution if benefits outweigh risks. Animal studies show risk and human studies not available or neither animal nor human studies done. D: Use in LIFE-THREATENING emergencies when no safer drug available. Positive evidence of human fetal risk. X: Do not use in pregnancy. Risks involved outweigh potential benefits. Safer alternatives exist. NA: Information not available.Pharmacology
Mechanism of Action
Kallikrein inhibitor; binds to plasma kallikrein and inhibits its proteolytic activity
Plasma kallikrein is a protease that cleaves high-molecular-weight-kininogen (HMWK) to generate cleaved HMWK and bradykinin, a potent vasodilator that increases vascular permeability resulting in swelling and pain associated with HAE
In patients with HAE caused by C1-inhibitor deficiency or dysfunction, normal regulation of plasma kallikrein activity is not present, which leads to uncontrolled increases in plasma kallikrein activity and results in angioedema attacks
Absorption
Peak plasma time: 5 hr
Peak plasma concentration at steady-state
- 110 mg/day: 97.8 ng/mL
- 150 mg/day: 158 ng/mL
AUC at steady-state
- 110 mg/day: 1,600 ng⋅hr/mL
- 150 mg/day: 2,770 ng⋅hr/mL
Steady-state
- Reached at days 6-12
- Exposure at steady state is ~5x that after a single dose
Effect of food
- No differences of peak plasma concentration and AUC with high-fat meal
- Median peak plasma time was delayed by 3 hr
Distribution
Protein bound: ~99%
Blood-to-plasma ratio: ~0.92
Metabolism
Metabolized by CYP2D6 and CYP3A4
Elimination
Half-life: ~93 hr
Excretion: Urine (~9% [3.4% unchanged]); feces (79%)
Administration
Oral Administration
Administer with food
Storage
Store at 20-25ºC (68-77ºF); excursions permitted to 15-30ºC (59-86ºF)
