PONLIMSI vs TEPMETKO
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Ponlimsi is a small molecule inhibitor of the bromodomain and extraterminal (BET) family of proteins, specifically BRD2, BRD3, BRD4, and BRDT. It binds to acetyl-lysine recognition motifs, displacing BET proteins from chromatin, thereby inhibiting transcription of oncogenes such as MYC and BCL2.
Tepotinib is a highly selective, ATP-competitive inhibitor of the mesenchymal-epithelial transition (MET) receptor tyrosine kinase, including the MET exon 14 skipping variant. It inhibits MET phosphorylation and downstream signaling pathways, thereby reducing tumor cell proliferation and migration.

Terminal half-life is 24 hours (range 20-28 h), supporting once-daily dosing.
Terminal elimination half-life approximately 12-15 hours in patients, supporting twice-daily dosing.
Primarily renal (60% unchanged) and biliary (30% as metabolites), with 10% fecal.
Primarily fecal (≥80% of absorbed dose), with renal excretion accounting for <5% as unchanged drug.
