LEQSELVI vs SPRX-105
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
LEQSELVI is a selective estrogen receptor degrader (SERD) that binds to estrogen receptors (ER), inducing their degradation and blocking ER-mediated signaling.
SPRX-105 is a dual dopamine D2 and serotonin 5-HT1A receptor partial agonist, functioning as a postsynaptic antagonist and presynaptic agonist at D2 receptors, and as a partial agonist at 5-HT1A receptors, modulating neurotransmitter release.
LEQSELVI is not a recognized pharmaceutical name. No dosing information available.
SPRX-105 is administered orally at a dose of 50 mg once daily.

Terminal elimination half-life is approximately 12 hours in healthy adults; may be prolonged in patients with moderate to severe hepatic impairment.
12-15 hours in healthy adults; extended to 24-30 hours in renal impairment.
Primarily excreted as unchanged drug via renal elimination (approximately 70% of dose), with biliary/fecal excretion accounting for about 20%.
Primarily renal (70-80% unchanged) with 15-20% biliary/fecal elimination.
