Brief Summary
This is a Phase III, 2-arm, randomised, open-label, multicentre, global study assessing the efficacy and safety of neoadjuvant Dato-DXd plus durvalumab followed by adjuvant durvalumab with or without chemotherapy compared with neoadjuvant pembrolizumab plus chemotherapy followed by adjuvant pembrolizumab with or without chemotherapy in participants with previously untreated TNBC or hormone receptor-low/HER2-negative breast cancer.
Study details include:
• The study duration will be up to 82 months after the first participant has been randomised.
• The treatment duration will be approximately 57 weeks (24 weeks of treatment in the neoadjuvant setting followed by surgery 25 days to 6 weeks after conclusion of neoadjuvant treatment or following early discontinuation, then 27 weeks of treatment in the adjuvant setting). Treatment duration will be longer for participants receiving up to 1 year of adjuvant olaparib treatment. Adjuvant radiotherapy may be given concurrently with adjuvant durvalumab or pembrolizumab monotherapy but not concurrently with adjuvant chemotherapy. Adjuvant endocrine therapy for hormone receptor-low tumours is permitted per investigator’s discretion (Note: participants cannot receive adjuvant CDK4/6 inhibitor therapy, including abemaciclib and ribociclib). All participants will receive study intervention in the neoadjuvant and adjuvant setting. Note, endocrine therapy is not considered study intervention and as such will not be provided by AstraZeneca.
• The on-treatment visit frequency will be weekly to Q3W. |
