Summary

This trial will study whether adding pertuzumab to standard chemotherapy and trastuzumab improves outcomes in patients with operable HER2-positive breast cancer.

Who is the study for?

This trial is for individuals with non-metastatic, operable HER2-positive primary breast cancer. Participants must have completed surgery within the last 8 weeks and be able to start chemotherapy within 7 days of joining. They should have a normal heart function (LVEF ≥55%), an ECOG performance status ≤1, known hormone receptor status, and agree to use effective contraception. Exclusions include prior breast cancer or systemic cancer treatments, current pregnancy or lactation, other serious illnesses that could interfere with treatment, and sensitivity to study drugs.

What is being tested?

The trial is testing the effectiveness of adding Pertuzumab to a standard adjuvant therapy regimen for HER2-positive breast cancer patients. This includes Trastuzumab and various chemotherapies like Cyclophosphamide and Paclitaxel in a randomized comparison against placebo plus the same additional therapies. The goal is to see if Pertuzumab improves outcomes when used alongside these existing treatments.

What are the potential side effects?

Potential side effects may include allergic reactions to medication components, heart problems due to Trastuzumab or Pertuzumab, infusion-related reactions from any administered drugs, as well as common chemotherapy side effects such as fatigue, nausea/vomiting, hair loss (alopecia), low blood cell counts leading to increased infection risk or bleeding complications.

Experimental Treatment

Placebo Group

Group I: Pertuzumab + Trastuzumab + ChemotherapyExperimental Treatment9 Interventions

Participants will receive pertuzumab (840 mg loading dose, then 420 mg) and trastuzumab (8 mg/kg loading dose, then 6 mg/kg) intravenously (IV) every 3 weeks (Q3W) for 1 year (maximum 18 cycles) in combination with 1 of the following IV chemotherapy regimen (anthracycline-based or nonanthracycline-based) per Investigator's choice: 1) 3-4 cycles (Q3W) of 5-fluorouracil 500-600 mg/m\^2 + epirubicin 90-120 mg/m\^2 or doxorubicin 50 mg/m\^2 + cyclophosphamide 500-600 mg/m\^2 followed by either 3-4 cycles of docetaxel Q3W (100 mg/m\^2 for 3 cycles, 75 mg/m\^2 in first cycle and 100 mg/m\^2 in subsequent cycles, or 75 mg/m\^2 for 4 cycles) or 12 cycles of paclitaxel 80 mg/m\^2 once weekly (QW); 2) 4 cycles (Q3W) of doxorubicin 60 mg/m\^2 or epirubicin 90-120 mg/m\^2 + cyclophosphamide 500-600 mg/m\^2 followed by either 3-4 cycles of docetaxel Q3W or 12 cycles of paclitaxel QW (as described in Option 1); 3) 6 cycles (Q3W) of docetaxel 75 mg/m\^2 + carboplatin area under the curve (AUC) 6 (up to 900 mg).
