AstraZeneca PLC (LSE/STO/Nasdaq: LON:AZN) disclosed today that the final overall survival (OS) results from the TROPION-Breast01 Phase III trial did not meet the statistical significance. The study evaluated the efficacy of datopotamab deruxtecan (Dato-DXd) in patients with inoperable or metastatic hormone receptor (HR)-positive, HER2-low or negative breast cancer who had previously undergone endocrine-based therapy and at least one systemic therapy.
Despite not achieving statistical significance in the final OS analysis, the trial had previously met its dual primary endpoint of progression-free survival (PFS). The PFS results, which were presented at the 2023 European Society for Medical Oncology Congress, showed a statistically significant and clinically meaningful improvement. Additionally, patient-reported outcomes also indicated an improvement. These findings were recently published in the Journal of Clinical Oncology.
The safety profile of datopotamab deruxtecan was consistent with prior analyses, with lower rates of Grade 3 or higher treatment-related adverse events compared to chemotherapy. The rates of all grade interstitial lung disease (ILD) remained low, with no new Grade 3 or higher ILD events observed.
AstraZeneca (NASDAQ:AZN)'s Executive Vice President, Oncology R&D, Susan Galbraith, stated that despite the advanced treatment landscape for metastatic HR-positive breast cancer, there is evidence of the clinical value of datopotamab deruxtecan in this setting. The company will continue discussions with regulatory authorities and apply insights from these results to their clinical development program for the drug in breast cancer.
Daiichi Sankyo's Global Head of R&D, Ken Takeshita, noted that datopotamab deruxtecan had previously shown a significant progression-free survival benefit, a result supported by multiple meaningful secondary measures including patient-reported outcomes. He expressed Daiichi Sankyo's commitment to making datopotamab deruxtecan another potential option for patients.
Datopotamab deruxtecan, a TROP2-directed DXd antibody-drug conjugate (ADC) discovered by Daiichi Sankyo, is being jointly developed by AstraZeneca and Daiichi Sankyo. The results will be presented at a forthcoming medical meeting and shared with regulatory authorities.
The TROPION-Breast01 trial is part of a comprehensive global clinical development program, which includes additional Phase III trials evaluating datopotamab deruxtecan as a treatment for various types of breast cancer.
