A Phase IIIB, Multinational, Multicenter, Randomized, Open-Label Study to Evaluate Patient Preference for Home Administration of Fixed-Dose Combination of Pertuzumab and Trastuzumab for Subcutaneous Administration in Participants With Early or Locally Advanced/Inflammatory HER2-Positive Breast Cancer
In Brief
A Phase 3 clinical trial evaluating Fixed Dose Combination of Pertuzumab and Trastuzumab for Subcutaneous Use (PH FDC SC), Pertuzumab IV, and 5 other interventions for Early Breast Cancer and 2 related conditions. Completed, enrolled 346 participants across 45 sites in 17 countries.
Detailed Summary
This is a Phase IIIb, multinational, multicenter, randomized, open-label study to evaluate patient preference of the fixed-dose combination of pertuzumab and trastuzumab for subcutaneous use (PH FDC SC) administration in the home setting compared with the hospital setting during the cross-over period of adjuvant treatment in participants with early or locally advanced/inflammatory human epidermal growth factor receptor 2-positive (HER2+) breast cancer.

Interventions
PH FDC SC is administered subcutaneously (SC) as a fixed non-weight-based dose. A loading dose of 1200 milligram (mg) pertuzumab, 600 mg trastuzumab, and 30,000 units of recombinant human PH20 hyaluronidase (rHuPH20) is given in the first cycle (1 cycle is 21 days). In subsequent cycles, maintenance doses of 600 mg pertuzumab, 600 mg trastuzumab, and 20,000 units rHuPH20 are administered once every 3 weeks (Q3W).
Pertuzumab is given as a fixed dose of 840 mg intravenous (IV) loading dose and then 420 mg IV for subsequent maintenance doses once every 3 weeks.
Trastuzumab is given as an 8 milligram per kilogram (mg/kg) intravenous (IV) loading dose and then 6 mg/kg IV for subsequent maintenance doses once every 3 weeks.
Trastuzumab emtansine will be given at a dose of 3.6 mg/kg by intravenous (IV) infusion, once every 3 weeks.
Option 1: Docetaxel and carboplatin once every 3 weeks for 6 cycles; Option 2: Doxorubicin plus cyclophosphamide once every 3 weeks for 4 cycles, followed by a taxane (docetaxel once every 3 weeks for 4 cycles or paclitaxel once every week for 12 cycles); Option 3: Dose-dense doxorubicin plus cyclophosphamide (ddAC) once every 2 weeks for 4 cycles, followed by a taxane (docetaxel once every 3 weeks for 4 cycles or paclitaxel once every week for 12 cycles).
After completing their neoadjuvant therapy, participants will undergo surgical resection for early or locally advanced HER2+ breast cancer (if eligible for surgery). Participants may undergo breast-conserving surgery or mastectomy according to routine clinical practice. The surgery cannot be performed ≤2 weeks from the last systemic neoadjuvant therapy and must be performed ≤6 weeks after the last systemic neoadjuvant therapy.
After surgery, radiotherapy is to be given as clinically indicated and as per local practice or institutional standards. The selected radiotherapy regimen should be initiated within 4 weeks after surgery.
