FABHALTA vs VEOPOZ
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Fabhalta (iptacopan) is a complement factor B inhibitor that binds to factor B and prevents the formation of the alternative pathway C3 convertase, thereby inhibiting complement alternative pathway activation.
VEOPOZ (tirzepatide) is a dual glucose-dependent insulinotropic polypeptide (GIP) and glucagon-like peptide-1 (GLP-1) receptor agonist. It activates both GIP and GLP-1 receptors, leading to increased insulin secretion, decreased glucagon secretion, delayed gastric emptying, and reduced appetite.

Terminal elimination half-life is approximately 8 hours (range 6-10 hours), supporting twice-daily dosing for sustained complement inhibition.
Terminal elimination half-life is 4-6 hours in patients with normal renal function; prolonged to 12-24 hours in moderate renal impairment (CrCl 30-50 mL/min) and up to 48 hours in severe impairment (CrCl <30 mL/min).
Primarily renal (approximately 70% as unchanged drug) and biliary/fecal (approximately 30% as metabolites).
Primarily renal excretion as unchanged drug (85-90%); biliary/fecal elimination accounts for 10-15%.
