NeoadjuVAnt muLti-agENT Chemotherapy or Patritumab Deruxtecan With or Without endocrINE Therapy for High-risk HR+/HER2- Breast Cancer - VALENTINE Trial

Summary

VALENTINE is a parallel, non-comparative, three-arm, randomized 1:2:2 open-label, multicenter, exploratory study in women or men with primary operable HR+/HER2-negative breast cancer with ki67 ≥ 20% and/or high genomic risk (defined by gene signature) aiming at evaluating the clinical benefit and biological effects of HER3-DXd with/without letrozole as a neoadjuvant treatment regimen. The primary aim is to evaluate the ability of each treatment strategy to achieve a pCR at surgery. This study is exploratory and no formal comparison between treatment arms is intended. The inclusion of a chemotherapy treatment arm serves as an internal response control instead of using historical data as comparators. In addition, the chemotherapy control arm is the standard of care appropriate treatment in these patients, to include this arm will ensure the recruitment of the target patient population (patients should have indication for neoadjuvant chemotherapy) and allowing comparison of secondary endpoint such as safety and/or HrQoL.
