KANUMA vs PALYNZIQ
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Recombinant human lysosomal acid lipase (LAL) that catalyzes the hydrolysis of cholesteryl esters and triglycerides in lysosomes.
PALYNZIQ (pegvaliase-pqpz) is a recombinant phenylalanine ammonia lyase conjugated to polyethylene glycol. It converts phenylalanine to trans-cinnamic acid and ammonia, reducing blood phenylalanine levels in patients with phenylketonuria.
1 mg/kg intravenously over 4 hours once weekly.
2.4 mg subcutaneously once daily.

Terminal elimination half-life: approximately 2–5 hours (range 1.5–7.5 hours) in patients with LAL deficiency. Clinical context: half-life supports weekly intravenous dosing.
Approximately 60–80 hours (terminal half-life); supports weekly dosing regimen.
Primarily cleared via receptor-mediated endocytosis and lysosomal degradation; negligible renal or biliary/fecal elimination of active drug. <1% excreted unchanged in urine.
Renal (predominantly as intact pegylated enzyme); less than 5% fecal. No active metabolites.
