SCANLUX-300 vs SCANLUX-370
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
SCANLUX-300 (gadoxetate disodium) is a hepatobiliary MRI contrast agent that shortens T1 relaxation time, enhancing signal intensity in tissues. It is taken up by hepatocytes via OATP1B1/1B3 transporters and excreted into bile via MRP2, allowing both dynamic and hepatobiliary phase imaging.
Radiopaque contrast agent that contains iodine, attenuates X-rays, enhancing vascular and tissue visualization during imaging.
30 mg/m² IV over 1 hour every 4 weeks.
The typical adult dose of SCANLUX-370 is 0.1 mg/kg administered intravenously as a single dose, up to a maximum of 7 mg.

Terminal elimination half-life is 3.5 hours (range 2.8–4.5 h); may be prolonged in hepatic impairment (up to 7 h).
The terminal elimination half-life of SCANLUX-370 is approximately 1.5-2 hours in patients with normal renal function. This short half-life allows for rapid clearance and minimal accumulation with repeated dosing.
Renal excretion of unchanged drug accounts for approximately 30% of the administered dose; fecal/biliary elimination accounts for about 60% (via hepatobiliary secretion into feces); minimal excretion via other routes.
SCANLUX-370 is primarily eliminated via renal excretion, with approximately 85-90% of the dose recovered unchanged in urine within 24 hours. The remaining 10-15% is excreted unchanged in feces via biliary elimination.
