IMpassion031 Trial Design

2Treatment groups
Experimental Treatment
Placebo Group
Group I: Atezolizumab and ChemotherapyExperimental Treatment6 Interventions
Participants received atezolizumab (840 milligrams [mg]) via intravenous (IV) infusion every 2 weeks in combination with nab-paclitaxel (125 milligrams per square meter [mg/m^2]) via IV infusion every week for 12 weeks, followed by atezolizumab (840 mg) every 2 weeks in combination with doxorubicin (60 mg/m^2) and cyclophosphamide (600 mg/m^2) every 2 weeks via IV infusions with filgrastim/pegfilgrastim support for 4 doses. Participants continued to receive unblinded atezolizumab post-surgery at a fixed dose of 1200 mg by IV infusion every 3 weeks for 11 doses, for a total of approximately 12 months of atezolizumab therapy.
Group II: Placebo and ChemotherapyPlacebo Group6 Interventions
Participants received placebo matched to atezolizumab via IV infusion every 2 weeks in combination with nab-paclitaxel (125 mg/m^2) via IV infusion every week for 12 weeks, followed by placebo matched to atezolizumab every 2 weeks in combination with doxorubicin (60 mg/m^2) and cyclophosphamide (600 mg/m^2) every 2 weeks via IV infusions with filgrastim/pegfilgrastim support for 4 doses. Participants will be unblinded post-surgery and will continue to be followed.
