To Reduce the Use of Chemotherapy in Postmenopausal Patients With ER-positive and HER2-positive Breast Cancer (TOUCH)

Summary

This is a phase II open-label, multicentre, randomized trial. The study assesses the treatment of postmenopausal patients with hormone receptor positive/HER2 positive early breast cancer with neoadjuvant palbociclib in combination with hormonal therapy and HER2 blockade, versus the treatment with paclitaxel in combination with HER2 blockade.
