BREXAFEMME vs EVEX
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
BREXAFEMME (ibrexafungerp) inhibits glucan synthase, an enzyme involved in fungal cell wall synthesis, disrupting cell wall integrity and causing fungal cell death.
Estrogen receptor agonist; binds to and activates nuclear estrogen receptors, leading to gene transcription and cellular effects in target tissues.
200 mg orally once daily.
0.625-1.25 mg orally once daily; or 0.3-0.625 mg vaginally once daily for 21 days with 7 days off.

The terminal elimination half-life of ibrexafungerp is approximately 20-30 hours in healthy subjects, supporting once-daily oral dosing without need for a loading dose.
Terminal elimination half-life is 12-24 hours, with a mean of approximately 18 hours. Due to significant enterohepatic recirculation, the half-life may be prolonged in patients with hepatic impairment or when administered with drugs that inhibit recirculation.
Ibrexafungerp is primarily eliminated via the biliary/fecal route. In clinical studies, approximately 51% of the dose was recovered in feces (as unchanged drug and metabolites) and ~1% in urine. Renal excretion is negligible.
Primarily hepatic metabolism with renal excretion of metabolites; approximately 60% of a dose is excreted in urine as conjugates (glucuronides and sulfates) and 30% in feces via biliary elimination. Less than 5% is excreted unchanged in urine.
