Description of intervention(s) / exposure
Treatment: Drugs - Dato-DXd
Treatment: Drugs - Durvalumab
Treatment: Drugs - Pembrolizumab
Treatment: Drugs - Doxorubicin
Treatment: Drugs - Epirubicin
Treatment: Drugs - Cyclophosphamide
Treatment: Drugs - Paclitaxel
Treatment: Drugs - Carboplatin
Treatment: Drugs - Capecitabine
Treatment: Drugs - Olaparib

Experimental: Dato-DXd plus durvalumab - Participants receive durvalumab every 3 weeks (Q3W) + Dato-DXd Q3W as neoadjuvant therapy prior to surgery; followed by 9 cycles of durvaluamb Q3W as adjuvant therapy post-surgery. Adjuvant chemotherapy may be given in combination with durvalumab only if participants have residual disease.

Olaparib may be given for participants with gBRCA-positive tumours and residual disease

Adjuvant chemotherapy may be one of these:

1. Doxorubicin (Q3W) or epirubicin (Q3W) + cyclophosphamide (Q3W) for 4 cycles (12 weeks) followed by paclitaxel (weekly) and carboplatin (weekly or Q3W) for 4 cycles (12 weeks);
2. Doxorubicin (Q3W) or epirubicin (Q3W) + cyclophosphamide (Q3W) for 4 cycles (12 weeks) followed by paclitaxel (weekly) for 4 cycles (12 weeks);
3. Carboplatin (weekly or Q3W) + paclitaxel (weekly) for 4 cycles (12 weeks);
4. Capecitabine (Q3W) for 8 cycles.

Active comparator: Pembrolizumab plus chemotherapy - Participants receive pembrolizumab every 3 weeks (Q3W) + paclitaxel weekly + carboplatin (weekly or Q3W) x 4 cycles, followed by pembrolizumab Q3W + (doxorubicin OR epirubicin) + cyclophosphamide Q3W x 4 cycles as neoadjuvant therapy prior to surgery; followed by 9 cycles of pembrolizumab Q3W as adjuvant therapy post-surgery. Adjuvant capecitabine (Q3W) for 8 cycles may be given in combination with pembrolizumab only if participants have residual disease. Olaparib may be given for participants with gBRCA-positive tumours and residual disease.
