ELDECORT vs POHERDY
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Corticosteroid binding to glucocorticoid receptors, leading to anti-inflammatory and immunosuppressive effects via inhibition of phospholipase A2, reduction of prostaglandins and leukotrienes, and modulation of cytokine production.
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).
Initial: 5-60 mg orally once daily, adjusted based on response; typical maintenance: 5-15 mg orally once daily.
POHERDY: No approved drug. No dosing available.

Terminal elimination half-life is 3.5 ± 1.2 hours in adults with normal renal function; prolonged to 6–8 hours in severe renal impairment (CrCl <30 mL/min).
Terminal half-life 12–18 hours (mean 15 h); requires dose adjustment in renal impairment (CrCl <30 mL/min)
Renal excretion of unchanged drug accounts for approximately 60% of the dose; fecal elimination contributes about 30% due to biliary secretion; the remaining 10% is metabolized.
Renal: 60% unchanged; fecal/biliary: 30%; 10% metabolized
