AstraZeneca and Daiichi Sankyo have officially submitted a new Biologics License Application for accelerated approval in the US for datopotamab deruxtecan for the treatment of adult patients with locally advanced or metastatic epidermal growth factor receptor-mutated non-small cell lung cancer who have received prior systemic therapies, including an EGFR-directed therapy.

This BLA is based on results from the TROPION-Lung05 Phase II trial and supported by data from the TROPION-Lung01 Phase III and TROPION-PanTumor01 Phase I trials. New results from a pooled analysis of patients with previously treated EGFR-mutated NSCLC in the TROPION-Lung05 and TROPION-Lung01 trials.

Susan Galbraith, Executive Vice President, Oncology R&D, AstraZeneca, said: “TROPION-Lung01 was designed to test the potential to improve upon standard-of-care chemotherapy in a broad, previously treated, advanced lung cancer patient population. The results, together with data from TROPION-Lung05, showed an especially pronounced benefit for patients with an EGFR mutation which informed our discussions with the FDA and the decision to seek accelerated approval of datopotamab deruxtecan in this patient population. TROPION-Lung01 has also provided exciting exploratory data supporting our biomarker development, which will be validated in ongoing and planned Phase III lung cancer trials.”

Ken Takeshita, MD, Global Head, R&D, Daiichi Sankyo, said: “Treating EGFR-mutated non-small cell lung cancer is incredibly challenging following disease progression given that the complexity and variability of these mutations often lead to resistance. The potential approval of datopotamab deruxtecan could offer renewed hope for patients with this formidable disease.”

Note that, Datopotamab deruxtecan is a specifically engineered TROP2-directed DXd antibody drug conjugate discovered by Daiichi Sankyo and being jointly developed by AstraZeneca and Daiichi Sankyo.
