Positive high-level results from the TROPION-Lung01 phase III trial showed datopotamab deruxtecan (Dato-DXd) demonstrated a statistically significant improvement for the dual primary endpoint of progression-free survival (PFS) compared to docetaxel, the current standard of care chemotherapy, in patients with locally advanced or metastatic non-small cell lung cancer (NSCLC) treated with at least one prior therapy.
For the dual primary endpoint of overall survival (OS), the data were not mature and an early trend was observed in favour of datopotamab deruxtecan versus docetaxel that did not meet the prespecified threshold for statistical significance at this interim analysis. The trial will continue as planned to assess OS with greater maturity. The investigators and participants will remain blinded to the results.
The safety profile of datopotamab deruxtecan was consistent with previous clinical trials with no new safety signals identified. All grade interstitial lung disease was generally consistent with prior clinical trials, with the majority being low grade. Some Grade 5 events were observed.
Datopotamab deruxtecan is a specifically engineered TROP2-directed DXd antibody drug conjugate (ADC) being jointly developed by AstraZeneca and Daiichi Sankyo.
