Abstract excerpt
Osimertinib is a third-generation epidermal growth factor receptor (EGFR) tyrosine kinase inhibitor with proven efficacy in EGFR-mutant non-small cell lung cancer (NSCLC), including patients with central nervous system (CNS) disease. However, pharmacokinetic (PK) studies demonstrate low CNS penetration (CSF:plasma 0.8%-22%), largely due to ABCB1/ABCG2 efflux. OB-001, a KinetiSol amorphous solid dispersion...
