FOCINVEZ vs KETOZOLE
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
FOCINVEZ is a small-molecule inhibitor of the interaction between the N-terminal domain of the androgen receptor (AR) and the AR N-terminal domain coactivator binding site, thereby blocking AR-mediated gene transcription and inhibiting prostate cancer cell growth.
Ketoconazole is an imidazole antifungal agent that inhibits fungal cytochrome P450 14α-demethylase, thereby blocking the conversion of lanosterol to ergosterol, a key component of the fungal cell membrane. This leads to increased membrane permeability and cell death.
Intravenous: 1.5 mg/kg every 6 hours; maximum single dose: 200 mg.
200 mg orally once daily with food.

Terminal elimination half-life: 12-15 hours; allows twice-daily dosing in most patients, extended in renal impairment (up to 30-40 hours in severe impairment).
Terminal elimination half-life is approximately 2 hours (range 1.5–3.5 hours). Clinically, duration of antifungal effect extends beyond plasma half-life due to persistent tissue levels.
Renal: 70% (unchanged drug), Biliary/Fecal: 20% (metabolites), Other: 10% (minor pathways).
Primarily hepatic metabolism; renal excretion of unchanged drug <1%. Biliary/fecal excretion accounts for ~20-35% of metabolites.
