Summary

The main purpose of this study is to learn if the usual chemotherapy given before surgery (neoadjuvant therapy) for breast cancer plus the experimental drug, atezolizumab, is better than the usual chemotherapy plus a placebo. (A placebo is a drug that looks like the study drug but contains no medication.) The usual chemotherapy in this study is paclitaxel (WP) and carboplatin followed by doxorubicin and cyclophosphamide (AC) or epirubicin and cyclophosphamide (EC). Usually, after neoadjuvant therapy and surgery for triple negative breast cancer, no additional treatment is given unless the cancer returns. This study will also look at continuing treatment after surgery with atezolizumab or the placebo. To be better, atezolizumab given with the neoadjuvant therapy should be better at: 1) decreasing the amount of tumor in the breast than the placebo given with the usual chemotherapy and 2) decreasing the chance of the cancer from returning after surgery.

Another purpose of this study is to test the good and bad effects of atezolizumab when added to the usual chemotherapy. Atezolizumab may keep your cancer from growing but it can also cause side effects.

Conditions

Interventions

DRUG

Placebo

Following randomization, patients will receive Paclitaxel 80 mg/m2 IV weekly x 12 doses + Carboplatin AUC of 5 IV Day 1 every 3 weeks for 4 cycles + placebo IV Day 1 every 3 weeks for 4 doses. Followed 2-3 weeks later by Doxorubicin (A) 60 mg/m2 IV + cyclophosphamide (C) 600 mg/m2 IV Day 1 every 2 or 3 weeks for 4 cycles OR Epirubicin (E) 90 mg/m2 IV + cyclophosphamide (C) 600 mg/m2 IV Day 1 every 2 or 3 weeks for 4 cycles. \+ placebo IV Day 1 every 3 weeks for 3 to 4 doses depending on AC/EC schedule used. Approximately 3-4 weeks later: Surgery (Lumpectomy or mastectomy and axillary staging), followed by placebo IV Day 1 every 3 weeks after surgery until 1 year after the first dose.

DRUG

Atezolizumab

Following randomization, patients will receive Paclitaxel 80 mg/m2 IV weekly x 12 doses + Carboplatin AUC of 5 IV Day 1 every 3 weeks for 4 cycles + Atezolizumab 1200 mg Day 1 every 3 weeks for 4 doses. Followed 2-3 weeks later by Doxorubicin (A) 60 mg/m2 IV + cyclophosphamide (C) 600 mg/m2 IV Day 1 every 2 or 3 weeks for 4 cycles OR Epirubicin (E) 90 mg/m2 IV + cyclophosphamide (C) 600 mg/m2 IV Day 1 every 2 or 3 weeks for 4 cycles. \+ Atezolizumab 1200 mg Day 1 every 3 weeks for 3 to 4 doses depending on AC/EC schedule used. Approximately 3-4 weeks later: Surgery (Lumpectomy or mastectomy and axillary staging), followed by Atezolizumab 1200 mg Day 1 every 3 weeks after surgery until 1 year after the first dose.
