Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Recombinant interleukin-2 (IL-2) that activates cellular immunity by promoting proliferation and differentiation of T cells, natural killer cells, and lymphokine-activated killer cells; stimulates cytokine release including TNF, IL-1, and IFN-gamma.
Dimethyl fumarate (DMF) is a methyl ester of fumaric acid. The exact mechanism of action in multiple sclerosis is unknown. It is thought to activate the nuclear factor (erythroid-derived 2)-like 2 (Nrf2) pathway, which induces antioxidant response elements and upregulates cytoprotective genes, reducing oxidative stress and inflammation.
600,000 IU/kg (0.037 mg/kg) intravenously every 8 hours for 14 doses, repeated after 9 days for a maximum of 28 doses per course.
240 mg orally twice daily.

Terminal elimination half-life is approximately 85 minutes (range 25-195 minutes) after intravenous infusion; clinical context: short half-life necessitates continuous infusion for sustained immunomodulatory effect.
The terminal elimination half-life of monomethyl fumarate (MMF) is approximately 1 hour. Due to rapid metabolism and elimination, MMF does not accumulate with multiple doses. No context of clinical significance is observed for accumulation.
Renal (primarily via glomerular filtration and tubular reabsorption with subsequent metabolism; <1% excreted unchanged in urine); fecal/biliary elimination is negligible.
Dimethyl fumarate is extensively metabolized; less than 1% is excreted unchanged in urine. The major metabolite, monomethyl fumarate, is further metabolized via the tricarboxylic acid cycle. Excretion occurs primarily as CO2 via exhalation, with about 60% of a dose recovered as CO2. Renal excretion accounts for approximately 16% of the dose as metabolites, and fecal excretion accounts for about 1%.
