ALYQ vs SPRX-105
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
ALYQ (alectinib) is a selective and potent anaplastic lymphoma kinase (ALK) inhibitor. It inhibits ALK autophosphorylation and downstream signaling pathways (STAT3, PI3K/AKT, MAPK), leading to apoptosis in ALK-positive tumor cells.
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.
Intravenous: 400 mg on Day 1, then 200 mg daily for 4 days; total 5 doses per cycle.
SPRX-105 is administered orally at a dose of 50 mg once daily.

Terminal elimination half-life is approximately 6-8 hours in adults with normal renal function; prolonged in renal impairment.
12-15 hours in healthy adults; extended to 24-30 hours in renal impairment.
Primarily renal excretion as unchanged drug (approximately 70-80%) and biliary/fecal elimination (20-30%) following intravenous administration.
Primarily renal (70-80% unchanged) with 15-20% biliary/fecal elimination.
