Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Polymyxin B binds to the lipid A portion of bacterial lipopolysaccharides, disrupting the outer membrane permeability and causing bacterial cell death. It is primarily active against Gram-negative bacteria.
RAXAR (revumenib) is a selective inhibitor of the menin-KMT2A protein-protein interaction. By binding to menin, it blocks the interaction with KMT2A (MLL1), thereby disrupting the transcription of oncogenic genes such as HOXA9 and MEIS1, leading to differentiation and apoptosis of leukemic cells.
Polymyxin B sulfate: 1.5-2.5 mg/kg/day intravenously divided every 12 hours, or 25,000-30,000 units/kg/day intramuscularly divided every 12 hours. Ophthalmic: 1-2 drops in affected eye every 4 hours. Topical: Apply to affected area 3-4 times daily.
Subcutaneous injection: 200 mg once daily, irrespective of timing of meals.

Terminal elimination half-life is approximately 2-3 hours in adults with normal renal function; prolonged to 20-40 hours in severe renal impairment (CrCl <10 mL/min), necessitating dose adjustment.
Terminal elimination half-life is 12-15 hours in healthy adults; prolonged in hepatic impairment (up to 25 hours).
Primarily renal excretion of unchanged drug via glomerular filtration. Approximately 60-70% of an intravenous dose is recovered in urine within 24 hours; minimal biliary/fecal elimination (<5%).
Primarily hepatic metabolism; renal excretion of unchanged drug <5%; biliary/fecal elimination as metabolites accounts for >90% of total clearance.
