Cristian Massacesi, Chief Medical Officer & Oncology Chief Development Officer, AstraZeneca, said: “The clinically meaningful activity, together with the favourable safety profile seen in the DESTINY-Lung02 trial helps establish the optimal dose of Enhertu at 5.4 milligrams per kilogram in previously-treated HER2-mutant non-small cell lung cancer. As we continue to explore the potential of this important medicine across multiple HER2-targetable tumour types, these data reaffirm the need to undertake HER2 testing in patients diagnosed with lung cancer.”
