Experimental Treatment

Group I: Cohort B: Tiragolumab and Atezolizumab + Nab-pac-carbo-ACExperimental Treatment8 Interventions

Participants with early TNBC in the neoadjuvant setting, who are eligible for surgery, will receive tiragolumab and atezolizumab every 2 weeks (Q2W) in combination with nab-paclitaxel weekly (QW) and carboplatin every 3 weeks (Q3W) for four cycles, followed by tiragolumab and atezolizumab in combination with doxorubicin and cyclophosphamide Q2W with granulocyte colony-stimulating factor (G-CSF; filgrastim or pegfilgrastim) or granulocyte-macrophage colony-stimulating factor (GM-CSF) support for four doses.

Group II: Cohort B: Tiragolumab and Atezolizumab + Nab-pac-ACExperimental Treatment7 Interventions

Participantswith early TNBC in the neoadjuvant setting, who are eligible for surgery, will receive tiragolumab and atezolizumab Q2W in combination with nab-paclitaxel QW for 12 weeks, followed by tiragolumab and atezolizumab in combination with doxorubicin and cyclophosphamide Q2W with G-CSF (filgrastim or pegfilgrastim) or GM-CSF support for four doses.

Group III: Cohort A: Tiragolumab and Atezolizumab + Nab-paclitaxelExperimental Treatment3 Interventions

Participants with first-line metastatic TNBC will receive tiragolumab and atezolizumab on Day 1 of every 28-day cycle plus nab-paclitaxel on Days 1, 8, and 15 of every 28-day cycle.
