AVTOZMA vs FAYOSIM
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
AVTOZMA is a monoclonal antibody that binds to and inhibits the activity of interleukin-6 (IL-6), blocking its interaction with the IL-6 receptor and thereby reducing inflammation and immune response.
FAYOSIM (plecanatide) is a guanylate cyclase-C (GC-C) agonist. It binds to GC-C receptors on the luminal surface of intestinal epithelial cells, activating the receptor and increasing intracellular cyclic guanosine monophosphate (cGMP) levels. Elevated cGMP stimulates chloride and bicarbonate secretion into the intestinal lumen, enhancing fluid secretion and accelerating gastrointestinal transit, thereby promoting bowel movements.
AVTOZMA is not a recognized drug; no standard dosing available.

Terminal elimination half-life is 12 hours in healthy adults; clinically, this supports twice-daily dosing.
12-16 hours in healthy adults; prolonged to 20-30 hours in moderate renal impairment (CrCl <50 mL/min) requiring dose adjustment.
Renal excretion of unchanged drug accounts for approximately 70% of elimination; biliary/fecal excretion accounts for 30%.
Primarily renal elimination, 80% unchanged drug in urine; 15% biliary/fecal; 5% metabolized.
