Seizures
- Seizures may occur
- Unknown if antiepileptic medications will prevent darolutamide-related seizures
- Advise patients of the risk of developing a seizure during therapy and of engaging in any activity where sudden loss of consciousness could cause harm to themselves or others
- Consider discontinuing therapy in patients who develop a seizure during treatment
- Inform patients to contact their healthcare provider right away if they have loss of consciousness or seizure
Drug interaction overview
- P-gp and CYP3A4 substrate
- BCRP transporter inhibitor; OATP1B1 and OATP1B3 inhibitor
-
Combined P-gp and strong or moderate CYP3A4 inducers
- Avoid coadministration
- Combined P-gp and strong or moderate CYP3A4 inducer decreases darolutamide exposure, which may decrease darolutamide activity
-
Combined P-gp and strong CYP3A4 inhibitors
- Combined P-gp and strong CYP3A4 inhibitor increases darolutamide exposure which may increase the risk of darolutamide adverse reactions
- Monitor more frequently for darolutamide adverse reactions and modify darolutamide dosage as needed
-
Breast cancer resistance protein (BCRP) substrates
- Darolutamide increases the AUC and peak plasma concentration of BCRP substrates, which may increase the risk of BCRP substrate-related toxicities
- Avoid use with drugs that are BCRP substrates where possible
- If used together, monitor more frequently for adverse reactions, and consider dose reduction of the BCRP substrate drug; refer to the prescribing information of the BCRP substrate when used concomitantly with darolutamide
Pregnancy & Lactation
Pregnancy
Safety and efficacy have not been established in females
Based on its mechanism of action, fetal harm and loss of pregnancy may occur
Animal embryofetal developmental toxicology studies were not conducted with darolutamide
There are no human data on the use in pregnant females
Contraception
- Males: Based on the mechanism of action, advise male patients with female partners of reproductive potential to use effective contraception during treatment and for 1 week after the last dose
Infertility
- Males: Based on animal studies, fertility may be impaired in males of reproductive potential
Lactation
Safety and efficacy have not been established in females
There are no data on the presence of darolutamide or its metabolites in human milk, the effect on the breastfed child, or the effect on milk production
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
Androgen receptor (AR) inhibitor; competitively inhibits androgen binding, AR nuclear translocation, and AR-mediated transcription
Keto-darolutamide (major metabolite) exhibited similar in vitro activity
In addition, darolutamide functioned as a progesterone receptor (PR) antagonist in vitro
Also, decreases prostate cancer cell proliferation in vitro and tumor volume in mouse xenograft models of prostate cancer
Absorption
Steady-state peak plasma concentration: 4.79 mg/L
Peak plasma time: ~4 hr (after single 600-mg dose)
Absolute bioavailability: ~30% (after 300-mg dose under fasted conditions)
AUC: 52.82 mcg⋅hr/mL
Steady-state is reached 2-5 days after repeated dosing with food, with a ~2-fold accumulation
Effect of food
- Bioavailability of darolutamide increased by 2- to 2.5-fold when administered with food
- Similar increase of exposure was observed for the active metabolite keto-darolutamide
Distribution
Vd: 119 L (IV)
Protein bound: 92% (darolutamide); 99.8% (active metabolite, keto-darolutamide)
Serum albumin is main binding protein for darolutamide and keto-darolutamide
Metabolism
Primarily metabolized CYP3A4, as well as by UGT1A9 and UGT1A1
Keto-darolutamide total exposure in plasma is 1.7-fold higher compared with darolutamide
Elimination
Half-life: ~20 hr
Clearance: 116 mL/min
Excretion
- Urine: 63.4%, ~7% unchanged
- Feces 32.4%; ~30% unchanged
- >95% of dose recovered within 7 days after administration
Administration
Oral Administration
Take with food
Swallow tablets whole
Missed dose: Take any missed dose as soon as possible before the next scheduled dose; do NOT double dose to make up for missed dose
Storage
Store at 20-25ºC (68-77ºF); excursions permitted to 15-30ºC (59-86ºF)
Keep bottle tightly closed after opening
