3. Patient must have locally confirmed advanced/unresectable or metastatic TNBC.
4. No prior treatment for metastatic (Stage IV) TNBC
5. Patient must have at least 1 lesion, not previously irradiated, that can be accurately measured
6. WHO/ECOG status at 0 or 1 at enrollment
Patients enrolled to Arm 6 (durvalumab and DS-8201a) Must provide documentation of locally determined advanced/unresectable or metastatic TNBC with HER2 low tumor expression (IHC 2+/ISH-, IHC 1+/ISH-, or IHC 1+/ISH untested)
Patients enrolled in Arm 8 (durvalumab + Dato-DXd) Must have PD-L1 positive tumor as determined by an IHC based assay
Exclusion criteria
1. History of allogeneic organ transplantation
2. Active or prior documented autoimmune or inflammatory disorders
3. Active infection including tuberculosis, hepatitis B (known positive HBV surface antigen [HBsAg] result), hepatitis C virus (HCV), or human immunodeficiency virus (positive HIV 1/2 antibodies)

2. Diagnosis of diabetes mellitus Type I or diabetes mellitus Type II requiring insulin treatment.
3. Any factors that increase the risk of QTc prolongation or risk of arrhythmic events, such as heart failure, hypokalemia, potential for torsades de pointes, congenital long QT syndrome, family history of long QT syndrome or unexplained sudden death under 40 years of age, or any concomitant medication known to prolong the QT interval
