Last clinically reviewed: July 2026 · OpiCalc Medical Review Team
Apalutamide is a nonsteroidal antiandrogen that inhibits androgen receptor (AR) nuclear translocation, DNA binding, and transcription of AR target genes. It also decreases AR-mediated tumor cell proliferation and increases apoptosis.
WINLEVI (clascoterone) is a topical androgen receptor inhibitor. It binds to the androgen receptor, preventing androgen-mediated signaling in sebocytes and inflammatory cells, thereby reducing sebum production and inflammation.
Metastatic castration-sensitive prostate cancer (m CSPC),Non-metastatic castration-resistant prostate cancer (nm CRPC)
FDA-approved for the topical treatment of acne vulgaris in patients aged 12 years and older.
240 mg orally once daily with or without food.
WINLEVI (clascoterone) topical cream 1%: Apply a thin layer to the affected skin areas twice daily, in the morning and evening.
Terminal elimination half-life is approximately 3 days (72 hours) for apalutamide and 3–5 days for the active metabolite N-desmethyl-apalutamide. The long half-life supports once-daily dosing and requires approximately 2–3 weeks to reach steady state.
Terminal elimination half-life is approximately 7.3 hours following topical application of clascoterone 1% cream. This supports twice-daily dosing for maintaining therapeutic drug levels.
Primarily metabolized by CYP2C8 and CYP3A4 to active metabolite N-desmethylapalutamide. Also involves glucuronidation by UGTs.
Clascoterone is metabolized primarily by CYP3A4 and CYP2C8 to its major metabolite, cortexolone. It undergoes extensive first-pass metabolism if absorbed systemically.
Apalutamide and its active metabolite N-desmethyl-apalutamide are eliminated primarily via hepatic metabolism and subsequent fecal excretion. Approximately 65% of the dose is recovered in feces (as unchanged drug and metabolites) and 24% in urine (primarily as metabolites). Renal excretion of unchanged drug is negligible.
Primarily fecal (approximately 84% of the dose) and renal (approximately 2.5% of the dose) following intravenous administration. Unchanged drug accounts for less than 1% in urine and feces.
Apalutamide is highly protein bound (>96%), primarily to albumin and alpha-1-acid glycoprotein. No significant displacement interactions are expected with other highly bound drugs.
Approximately 72% bound to plasma proteins (mainly albumin and alpha-1-acid glycoprotein).
Apparent volume of distribution (Vd/F) is approximately 200 L (2.7 L/kg for a 70 kg adult), indicating extensive distribution into tissues including the prostate and other androgen-responsive organs.
Following intravenous administration, volume of distribution is approximately 1.8 L/kg, indicating extensive tissue distribution.
Oral bioavailability is not precisely determined due to lack of an intravenous formulation, but absorption is at least 90% based on mass balance studies. Food does not significantly affect absorption, so it can be taken with or without food.
Systemic bioavailability is minimal after topical application of clascoterone 1% cream, with plasma concentrations typically below the limit of quantitation; the exact percentage is not determined, but systemic exposure is negligible (<1% of applied dose).
No dose adjustment required for mild to moderate renal impairment (e GFR 30-89 m L/min). For severe renal impairment (e GFR 15-29 m L/min), use with caution; no specific dose recommendation. Not studied in end-stage renal disease (e GFR <15 m L/min) or on hemodialysis.
No dosage adjustment required for renal impairment, as systemic absorption is minimal.
Mild hepatic impairment (Child-Pugh A): No dose adjustment. Moderate hepatic impairment (Child-Pugh B): Reduce dose to 120 mg once daily. Severe hepatic impairment (Child-Pugh C): Not recommended due to lack of data.
No dosage adjustment required for mild to moderate hepatic impairment (Child-Pugh A or B). Not studied in severe hepatic impairment (Child-Pugh C); use with caution.
Safety and efficacy not established; no approved pediatric dosing.
Approved for patients aged 12 years and older. Same dosing as adults: apply a thin layer of 1% cream twice daily to affected areas. Safety and efficacy in children under 12 years have not been established.
No specific dose adjustment required; consider comorbidities and potential for increased adverse effects based on renal and hepatic function.
No specific dosage adjustment needed. However, elderly patients may have more sensitive skin; monitor for local irritation. Systemic exposure is minimal.
None.
None.
Seizures: Discontinue permanently if seizure occurs during treatment.,Fractures and Falls: Increased risk of bone fractures and falls; assess bone density and manage accordingly.,Cardiovascular Events: Increased risk of hypertension, cardiac ischemia, and heart failure; monitor cardiovascular status.,Hypothyroidism: Monitor thyroid function before and during treatment; replacement therapy may be needed.,Embryo-Fetal Toxicity: Can cause fetal harm; advise males with female partners of reproductive potential to use effective contraception.
Local skin reactions including erythema, pruritus, and scaling may occur. Avoid contact with eyes, mouth, and mucous membranes. Not for oral, ophthalmic, or intravaginal use. Discontinue if signs of systemic toxicity or hypersensitivity develop. Use in pregnancy only if clearly needed; no adequate and well-controlled studies exist.
Pregnancy (can cause fetal harm),Women of reproductive potential (unless using effective contraception)
Hypersensitivity to clascoterone or any component of the formulation.
Avoid grapefruit and grapefruit juice due to potential CYP3A4 interaction. No other specific dietary restrictions; can be taken with or without food.
No specific food interactions are known. No dietary restrictions are required.
Apalutamide is contraindicated in pregnancy. Based on its mechanism of androgen receptor inhibition, it may cause fetal harm, including feminization of male fetuses and developmental abnormalities. Adequate animal reproduction studies have not been conducted; however, in rats, fetal malformations were observed at exposures below human clinical exposures. Effective contraception is required for females of reproductive potential during treatment and for 3 months after the last dose.
WINLEVI (clascoterone) is a topical androgen receptor inhibitor. No adequate and well-controlled studies in pregnant women. In animal reproduction studies, no evidence of fetal harm was observed following topical administration of clascoterone during organogenesis at doses up to 2.5 mg/kg/day in rats (systemic exposure ~27 times the MRHD based on AUC) and 50 mg/kg/day in rabbits (systemic exposure 4 times the MRHD). However, because systemic absorption is minimal, the risk is considered low. Per FDA labeling, use during pregnancy only if clearly needed. No known fetal risks by trimester; avoid use on large areas of broken skin.
It is unknown whether apalutamide or its metabolites are excreted in human milk. Due to potential for serious adverse reactions in breastfed infants, breastfeeding is not recommended during treatment and for at least 3 months after the last dose. M/P ratio is not available.
It is not known whether clascoterone is excreted in human milk after topical application. Systemically absorbed clascoterone is minimal; however, it is lipophilic and may partition into breast milk. No M/P ratio is available. Due to potential for serious adverse reactions in nursing infants, advise patients to avoid application to the breast area and to discontinue nursing or drug, taking into account importance of drug to mother.
No dosing adjustments have been established for pregnancy. Apalutamide is not indicated for use in pregnant women. Physiological changes in pregnancy may alter pharmacokinetics, but no data are available to guide dose modifications.
No dose adjustment required in pregnancy due to minimal systemic absorption and lack of pharmacokinetic changes reported. Use with caution for acne treatment during pregnancy; weigh benefit vs risk. Apply thin layer once daily; avoid use on large areas of damaged skin.
Apalutamide is an androgen receptor inhibitor used for non-metastatic castration-resistant prostate cancer (nm CRPC). It is a strong CYP3A4 inducer and moderate CYP2C8 inhibitor, requiring careful management of drug interactions. Monitor thyroid function and blood pressure. Concomitant use with warfarin or other anticoagulants may necessitate increased monitoring due to reduced efficacy. Apalutamide can cause seizures; avoid in patients with history of seizure disorders. Baseline and periodic serum lipid profiles and glucose levels are recommended. Dose reduction in severe hepatic impairment (Child-Pugh C) is suggested.
WINLEVI (clascoterone) is a topical androgen receptor inhibitor approved for acne vulgaris. Avoid use on broken or eczematous skin. Monitor for signs of hyperkalemia in patients with renal impairment or those taking medications affecting potassium. Application should be limited to 1 gram per day (approximately 4 pump actuations) to minimize systemic absorption. Can be used in conjunction with other topical acne therapies but may require adjustment of irritation potential.
