Trial overview

Official title: Neo ALTTO (Neoadjuvant Lapatinib and/or Trastuzumab Treatment Optimisation) Study: A randomised, multicenter open-label phase III study of neoadjuvant lapatinib, trastuzumab and their combination plus paclitaxel in women with HER2/ErbB2 positive primary breast cancer
Trial description: This is a randomised, open label multicenter Phase III study comparing the efficacy of neoadjuvant lapatinib plus paclitaxel, versus trastuzumab plus paclitaxel, versus concomitant lapatinib and trastuzumab plus paclitaxel given as neoadjuvant treatment in HER2/ErbB2 over-expressing and/or amplified primary breast cancer.
Patients will be randomised to receive either: lapatinib 1500 mg daily, trastuzumab 4 mg/kg intravenous (IV) load followed by 2 mg/kg IV weekly, or lapatinib 1000 mg daily with trastuzumab 4 mg/kg IV load followed by 2 mg/kg IV weekly for a total of 6 weeks. After this biological window, patients on monotherapy arms will continue on the same targeted therapy plus weekly paclitaxel 80 mg/m^2 for a further 12 weeks, up to definitive surgery. In the combination arm, patients will receive lapatinib 750 mg daily in combination with trastuzumab 2 mg/kg IV plus weekly paclitaxel 80mg/m^2 IV for a further 12 weeks, up to definitive surgery. After surgery, patients will receive three courses of adjuvant chemotherapy with 5-Fluorouracil Epirubicin Cyclophosphamide (FEC) followed by the same targeted therapy as in the biological window of the neoadjuvant setting for a further 34 weeks (in the combination arm, lapatinib dose will be 1000 mg daily in combination with trastuzumab). The planned total duration of the anti-HER2 therapy will be one year.
