BDTX-1535 abstract for AACR presentation is released. There is no clinical data, it is about science. This study was conducted mostly by scientists from MD Anderson Cancer Center including John Heymach, who is an expert in EGFR/HER2 mutations in NSCLC. They discovered that treatment of two classical EGFR mutations, Exon 19 deletions and L858R, by Osimertinib results in two different resistance outcomes. Patients with Exon 19 deletions usually develop C797S resistance mutation whereas patients with L858R develop multiple non-classical resistance mutations. They also found that non-classical mutations often co-exist with L858R in first-line patients, making Osimertinib treatment less effective. For these patients BDTX-1535 should be a better option.
