Summary
Brief summary (as posted)
This randomized study will assess the effect of adding bevacizumab to trastuzumab plus docetaxel in neoadjuvant therapy in participants with early stage human epidermal growth factor receptor 2 (HER2)-positive breast cancer. After 2 cycles of trastuzumab and docetaxel once every 3 weeks, participants with a response (change in standard uptake value \[SUV\]) of less than (\<) 70 percent (%) on Positron Emission Tomography (PET) will be randomized in a 2:1 ratio to receive Cycles 3 to 6 of trastuzumab (6 milligrams per kilogram \[mg/kg\]) and docetaxel (100 milligrams per square meter \[mg/m\^2\]) with or without bevacizumab (15 mg/kg). Participants with a response of greater than or equal to (\>/=) 70% will receive trastuzumab plus docetaxel in Cycles 3 to 6. All participants will receive trastuzumab alone in Cycle 7, and will undergo surgery (as per investigator's discretion) after Cycle 7 and between 4 and 6 weeks after the treatment perfusion of Cycle 6. After surgery, all participants will receive a further 11 cycles of trastuzumab plus radiotherapy (starting from 4-8 weeks after surgery during 4-6 weeks, according to site's standard practice) with or without hormonal therapy (mandatory if positive hormone receptors). Participants will be followed for up to 5 years from start of neoadjuvant treatment.
