Enhertu demonstrated strong and durable tumour responses in previously treated HER2-mutant advanced lung cancer in DESTINY-Lung02 Phase II trial
AstraZeneca and Daiichi Sankyo’s Enhertu showed objective response rates of 49% and 56% with 5.4mg/kg and 6.4mg/kg doses respectively in primary analysis. Enhertu provided a median progression-free survival of 9.9 months at 5.4mg/kg dose and 15.4 months at 6.4mg/kg dose with a median duration of response of 16.8 months seen at the 5.4 mg/kg dose and not reached at the 6.4 mg/kg dose. Favourable safety profile confirms 5.4mg/kg as optimal dose in this tumour type and reinforces role of Enhertu in this setting. Results from the primary analysis of the DESTINY-Lung02 Phase II trial showed
