Last verified: November 2016
This 2-arm, randomized, open-label study will evaluate the efficacy and safety of trastuzumab emtansine versus trastuzumab as adjuvant therapy in patients with HER2-positive breast cancer who have residual tumor present in the breast or axillary lymph nodes following preoperative therapy. Eligible patients will be randomized to receive either trastuzumab emtansine 3.6 mg/kg or trastuzumab 6 mg/kg intravenously every 3 weeks for 14 cycles. Radiotherapy and/or hormone therapy will be given in addition if indicated.

Primary Purpose: Treatment
Official Title: A Randomized, Multicenter, Open-Label Phase III Study to Evaluate the Efficacy and Safety of Trastuzumab Emtansine Versus Trastuzumab as Adjuvant Therapy for Patients With HER2-Positive Primary Breast Cancer Who Have Residual Tumor Present Pathologically in the Breast or Axillary Lymph Nodes Following Preoperative Therapy

Further study details as provided by Hoffmann-La Roche:

Primary Outcome Measures:
  • Invasive disease-free survival (IDFS): Time from randomization to ipsilateral invasive breast tumor recurrence, ipsilateral local-regional invasive breast cancer recurrence, distant recurrence, contralateral invasive breast cancer, or death of any cause [ Time Frame: up to 10 years ]

Secondary Outcome Measures:
  • Invasive disease-free survival including second non-breast cancers [ Time Frame: up to 10 years ]
  • Disease-free survival: Time from randomization to first occurrence of an IDFS event including second primary non-breast cancer or contralateral or ipsilateral ductal carcinoma in situ [ Time Frame: up to 10 years ]
  • Overall survival: Time from randomization to death of any cause [ Time Frame: up to 10 years ]
  • Distant recurrence-free interval: Time from randomization to date of distant breast cancer recurrence [ Time Frame: up to 10 years ]
  • Safety: Incidence of adverse events [ Time Frame: up to 10 years ]
  • Incidence of cardiac events: Death from cardiac cause or severe chronic heart failure (NYHA Class III or IV) [ Time Frame: up to 10 years ]
  • Patient reported outcomes: European Organization for Research and Treatment of Cancer (EORTC) Quality of Life Quetionnaire QLQ-C30/QLQ-BR23, EuroQol EQ-5d Questionnaire [ Time Frame: up to 10 years ]
