In the I-SPY2.2 trial, patients with high-risk stage 2/3 breast cancer received neoadjuvant datopotamab–deruxtecan plus durvalumab, followed by sequential chemotherapy with or without targeted therapy, with the option of early surgical resection after each block of therapy, showing that de-escalation of therapy is possible for several patient subgroups without compromising outcome and avoiding toxicity of standard chemotherapy.
