Abstract
Repotrectinib, a next-generation ROS1/TRK/ALK tyrosine kinase inhibitor, overcomes resistance due to acquired solvent-front mutations involving ROS1, NTRK1-3, and ALK. A bioanalytical assay for quantification of repotrectinib in mouse plasma and seven tissue-related matrices (brain, liver, spleen, kidney, small intestinal tissue, small intestinal content, and testis homogenates) was developed and validated
