Abstract Datopotamab deruxtecan (DATROWAY®) is a trophoblast cell surface antigen 2 (TROP2)-directed antibody-drug conjugate being developed by Daiichi Sankyo and AstraZeneca for the treatment of solid tumours. On 27 December 2024, datopotamab deruxtecan was approved in Japan for the treatment of adult patients with hormone receptor (HR) positive, human epidermal growth factor receptor 2 (HER2) negative unresectable or recurrent breast cancer after prior chemotherapy. The drug has since been approved on 17 January 2025 in the USA for the treatment of adult patients with unresectable or metastatic HR positive, HER2 negative breast cancer who have received prior endocrine-based therapy and chemotherapy for unresectable or metastatic disease. Datopotamab deruxtecan has also received a positive opinion in the EU. Regulatory review of datopotamab deruxtecan in breast cancer is underway in Canada and China. This article summarizes the milestones in the development of datopotamab deruxtecan leading to this first approval for the treatment of HR positive, HER2 negative breast cancer. © Springer Nature Switzerland AG 2025

How this classification was reachedexpand
Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
