OZILTUS vs WEGOVY
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
OZILTUS (alectinib) is a tyrosine kinase inhibitor that targets anaplastic lymphoma kinase (ALK) and RET. It blocks phosphorylation and downstream signaling pathways, including STAT3 and PI3K/AKT, leading to cell cycle arrest and apoptosis in ALK-positive tumors.
Semaglutide, a GLP-1 receptor agonist, increases insulin secretion, decreases glucagon secretion, delays gastric emptying, and reduces appetite via central GLP-1 receptor activation.
10 mg subcutaneously twice daily.
Subcutaneous injection 0.25 mg once weekly for 4 weeks, then increase to 0.5 mg once weekly for 4 weeks, then 1 mg once weekly for 4 weeks, then 1.7 mg once weekly for 4 weeks, then maintenance 2.4 mg once weekly.

The terminal elimination half-life is 12-15 hours in patients with normal renal function. This supports twice-daily dosing. In patients with moderate to severe renal impairment (CrCl <30 mL/min), the half-life may be prolonged to up to 30 hours, necessitating dose adjustment.
Terminal elimination half-life is approximately 1 week (6–8 days), supporting once-weekly subcutaneous dosing.
OZILTUS is primarily eliminated via renal excretion (65-70% as unchanged drug) and biliary/fecal excretion (20-25% as metabolites and unchanged drug). Approximately 5% is eliminated via other routes.
Primarily renal; approximately 97% of the dose is excreted unchanged in urine, with less than 3% in feces via biliary excretion.
