Details and patient eligibility

About

This single arm, multicenter study will evaluate the safety of assisted subcutaneous administration of trastuzumab in participants with HER2+ eBC. Participants who have completed the first 6 cycles of intravenous (IV) trastuzumab as part of the (neo)adjuvant treatment will be eligible to receive a further 12 cycles of trastuzumab in this study. Participants will receive IV trastuzumab at initial loading dose of 8 milligrams per kilogram (mg/kg) body weight (BW) for three-weekly (q3w) regimen and then recommended maintenance dose of 6 mg/kg BW q3w for the first 3 cycles (cycles 7-9) in hospital followed by subcutaneous (SC) administration of trastuzumab at a fixed dose of 600 mg q3w for next 3 cycles (Cycles 10-12) at hospital and SC administration of trastuzumab at a fixed dose of 600 mg q3w at home for the next 6 cycles (Cycles 13-18).

Inclusion criteria

• Histologically confirmed non-metastatic primary invasive adenocarcinoma of the breast
• HER2-positive disease immunohistochemistry (IHC)3+ or in situ hybridization (ISH) positive, in line with local reimbursement criteria and determined in a local laboratory that is experienced/certified in HER2-expression testing using an accurate and validated assay
• Eastern Cooperative Oncology Group (ECOG) performance status 0-1
• Hormonal therapy will be allowed as per institutional guidelines
• Left ventricular ejection fraction (LVEF) of greater than or equal to (>/=) 50% measured by echocardiography (ECHO) or multiple gated acquisition (MUGA) scan prior to first dose of trastuzumab SC, or, for those who were receiving trastuzumab when beginning the study, documented results within an acceptable limit from a cardiac assessment within 3 months prior to enrollment
• Participants have completed the first 6 cycles of trastuzumab IV as part of the (neo)adjuvant treatment
• No evidence of residual, locally recurrent or metastatic disease after completion of surgery and chemotherapy, (neo-adjuvant or adjuvant)
• Use of concurrent curative radiotherapy will be permitted

Exclusion criteria

• History of other malignancy which could affect compliance with the protocol or interpretation of results. Participants with curatively treated carcinoma in situ of the cervix or basal cell carcinoma, and patients with other curatively treated malignancies who have been disease-free for at least 5 years, are eligible
• Participants with severe dyspnea at rest or requiring supplementary oxygen therapy
• Participants with other concurrent serious diseases that may interfere with planned treatment, including severe pulmonary conditions/illness
• Serious cardiac illness or medical conditions that would preclude the use of trastuzumab, specifically: history of documented congestive heart failure (CHF), high-risk uncontrolled arrhythmias, angina pectoris requiring medication, clinically significant valvular disease, evidence of transmural infarction on electrocardiogram (ECG), diagnosed poorly controlled hypertension
• Known infection with human immunodeficiency virus (HIV), active hepatitis B virus (HBV) or hepatitis C virus (HCV)
• Pregnant or lactating women
• Women of childbearing potential and male participants with partners of childbearing potential who are unable or unwilling to use adequate contraceptive measures during study treatment
• Concurrent enrollment in another clinical trial using an investigational anti-cancer treatment, including hormonal therapy, bisphosphonate therapy and immunotherapy, within 28 days prior to the first dose of study treatment
• Known hypersensitivity to trastuzumab, murine proteins, to any of the excipients of Herceptin including hyaluronidase, or the adhesive of the SC device, or a history of severe allergic or immunological reactions, e.g. difficult to control asthma
• Inadequate bone marrow, hepatic or renal function

Experimental group

Description:

Participants with HER2+ eBC who completed the first 6 cycles of trastuzumab IV infusion as part of the (neo) adjuvant treatment will be included to continue to receive 12 cycles of trastuzumab to complete a total of 18 cycles of trastuzumab. Participants will receive trastuzumab IV infusion at initial loading dose of 8 mg/kg BW for q3w regimen as a part of neo adjuvant treatment before entering in the study and then recommended maintenance dose of 6 mg/kg BW q3w for the first 3 cycles (cycles 7-9) in hospital followed by SC administration of trastuzumab at a fixed dose of 600 mg q3w for next 3 cycles (Cycles 10-12) at hospital and SC administration of trastuzumab at a fixed dose of 600 mg q3w at home for the next 6 cycles (Cycles 13-18) (Each cycle=21 days).
