The European Medicines Agency (EMA) has validated two marketing authorisation applications (MAAs) for AstraZeneca and Daiichi Sankyo’s datopotamab deruxtecan (Dato-DXd) in two types of cancer. One MAA is for the treatment of adult patients with locally advanced or metastatic nonsquamous non-small cell lung cancer (NSCLC) who require systemic therapy following prior treatment. The other MAA is for the treatment of adult patients with unresectable or metastatic hormone receptor (HR)-positive, HER2-negative (IHC 0, IHC 1+ or IHC 2+/ISH-) breast cancer who have progressed on and are not suitable for endocrine therapy and received at least one additional systemic therapy.

The validations confirm the completion of the applications and commence the scientific review process by the EMA’s Committee for Medicinal Products for Human Use. The applications are based on data from the pivotal TROPION-Lung01 and TROPION-Breast01 Phase III trials presented during two Presidential Symposia at the 2023 European Society for Medical Oncology Congress.

Datopotamab deruxtecan is a specifically engineered TROP2-directed DXd antibody drug conjugate (ADC) discovered by Daiichi Sankyo and being jointly developed by AstraZeneca and Daiichi Sankyo.

Susan Galbraith, Executive Vice President, Oncology R&D, AstraZeneca, said: “Our ambition is for datopotamab deruxtecan to improve upon and replace conventional chemotherapy in the treatment of multiple cancer types. Today’s dual validation of our applications in lung and breast cancers brings this potential medicine a meaningful step closer to redefining treatment expectations for patients with two of the most common cancers in Europe.”

Ken Takeshita, MD, Global Head, R&D, Daiichi Sankyo, said: “The EMA validation is an important first step toward bringing this TROP2-directed antibody drug conjugate to eligible patients in Europe with nonsquamous lung cancer and HR-positive, HER2-negative breast cancer. This news builds on our recent regulatory progress in the US, where our lung cancer application has been accepted and our breast cancer application is underway, underscoring our commitment to changing the standard of care by developing new medicines to help as many patients worldwide as possible."

Additional regulatory submissions for datopotamab deruxtecan in lung cancer and breast cancer are underway in the US and globally.
