CAPEX vs POHERDY
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Corticosteroid with anti-inflammatory, antipruritic, and vasoconstrictive properties.
POHERDY is a monoclonal antibody targeting the human epidermal growth factor receptor 2 (HER2), binding to domain IV of the extracellular segment, thereby inhibiting ligand-independent HER2 signaling and mediating antibody-dependent cellular cytotoxicity (ADCC).
Topical application of a thin film twice daily to affected areas. Not for ophthalmic, oral, or intravaginal use.
POHERDY: No approved drug. No dosing available.

Terminal elimination half-life is approximately 1.5–2 hours. This short half-life supports twice-daily dosing for maintenance of therapeutic levels.
Terminal half-life 12–18 hours (mean 15 h); requires dose adjustment in renal impairment (CrCl <30 mL/min)
Primarily renal (hepatic metabolism to inactive metabolites; <1% excreted unchanged in urine). Fecal elimination accounts for <5%.
Renal: 60% unchanged; fecal/biliary: 30%; 10% metabolized
