Study Summary

This trial is studying how well paclitaxel, trastuzumab, and pertuzumab with or without atezolizumab works in treating patients with breast cancer that has spread to other parts of the body (metastatic).

Who is the study for?
This trial is for adults with HER2-positive metastatic breast cancer. Eligible participants have a tumor no larger than 3 cm, four or fewer brain metastases, measurable disease, and proper organ function. HIV-positive patients can join if they're on effective therapy. Pregnant women, those planning pregnancy, or lactating are excluded.Check my eligibility
What is being tested?
The study tests how well the usual therapy (paclitaxel, trastuzumab, pertuzumab) works with or without atezolizumab in treating first-line HER2-positive metastatic breast cancer. It's a randomized phase III trial where some patients will also receive a placebo instead of atezolizumab.See study design
What are the potential side effects?
Atezolizumab may cause immune-related side effects like inflammation in various organs; infusion reactions; fatigue; nausea; liver issues; skin rash and itching. The chemotherapy drugs can cause hair loss, nerve damage, low blood cell counts leading to increased infection risk.

Trial Design

2Treatment groups
Experimental Treatment
Active Control
Group I: Arm I (pertuzumab, trastuzumab, taxane therapy, atezolizumab)Experimental Treatment10 Interventions
Patients receive pertuzumab IV over 30-60 minutes on days 1 and 22, trastuzumab IV over 30-90 minutes on days 1 and 22, and paclitaxel IV over 60 minutes on days 1, 8, 15, 22, 29, and 36 or docetaxel IV over 60 minutes on days 1 and 22. Cycles repeat every 6 weeks in the absence of disease progression or unacceptable toxicity. Patients also receive atezolizumab IV over 30-60 minutes on day 22 of cycle 1 and days 1 and 22 of subsequent cycles. Cycles repeat every 6 weeks for 2 years in the absence of disease progression or unacceptable toxicity. Patients may undergo a biopsy at baseline. Patients undergo a CT or MRI at baseline, prior to weeks 10, 19, 28 and then at 9, 12, 15, 18, 21, and 24 months from study entry, every 3 months through year 3, every 6 months for years 4 and 5, and then every 6 months for years 6 through 10 from study entry. Patients undergo a bone scan at baseline, every 6 months from study entry, every 6 months through year 3, and every 12 months for years 4 and 5.
Group II: Arm II (pertuzumab, trastuzumab, taxane therapy, placebo)Active Control10 Interventions
Patients receive pertuzumab, trastuzumab, and paclitaxel or docetaxel as in Arm I. Patients also receive placebo IV 30-60 minutes on day 1 of cycle 22 and days 1 and 22 of subsequent cycles. Cycles repeat every 6 weeks for 2 years in the absence of disease progression or unacceptable toxicity. Patients may undergo a biopsy at baseline. Patients undergo a CT or MRI at baseline, prior to weeks 10, 19, 28 and then at 9, 12, 15, 18, 21, and 24 months from study entry, every 3 months through year 3, every 6 months for years 4 and 5, and then every 6 months for years 6 through 10 from study entry. Patients undergo a bone scan at baseline every 6 months from study entry, every 6 months through year 3, and every 12 months for years 4 and 5.
