Note: the use of filgrastim (non<br> pegylated form only) is authorized prior to the randomisation.<br><br> - Patients requiring the concomitant use of any forbidden treatment including: Any<br> other anti-cancer treatments not listed in the protocol, including chemotherapy,<br> radiotherapy, immunotherapy, targeted therapy or biologic therapy for cancer<br> treatment, Any investigational treatment.<br><br> - Any contra-indication to trastuzumab, paclitaxel, and pegfilgrastim respective SPCs<br> including:Hypersensitivity to trastuzumab, murine proteins, or to any of the<br> excipients listed in trastuzumab SPC, Severe dyspnea at rest due to complications of<br> advanced malignancy or requiring supplementary oxygen therapy, Hypersensitivity to<br> pegfilgrastim or filgrastim, or to any of the excipients listed in SPC, Hereditary<br> problems of fructose intolerance, Hypersensitivity to paclitaxel or to any<br> excipient, particularly macrogolglycerol ricinoleate, Patients with history of or<br> active cardiac disease including myocardial infarction (MI), angina pectoris<br> requiring medical treatment, congestive heart failure NYHA (New York Heart<br> Association) Class =II, other cardiomyopathy, cardiac arrhythmia requiring medical<br> treatment, clinically significant cardiac valvular disease, and hemodynamic<br> effective pericardial effusion.<br><br> - Active secondary malignancy unless this malignancy is not expected to interfere with<br> the evaluation of study endpoints and is approved by the sponsor.
