“considering that the majority of toxicology studies, including the pivotal 13-week rat and dog studies, tested the Form II (A) also used in clinical trials, results from toxicology studies are considered reliable for extrapolation to humans.”
100% or near-100% sequence homology of the entrectinib binding site in the toxicology species
“Sequence comparisons showed 100% or near 100% sequence homologies in the entrectinib binding site, building confidence on the theoretical validity of the selected species used for the safety validation.”
