Condition her2-positive carcinoma of breast
Treatment trastuzumab
Phase phase 3
Target HER2
Sponsor Celltrion
Collaborator Nippon Kayaku Co.,Ltd.
Start date June 2014
End date December 2016
Trial size 562 participants
Trial identifier NCT02162667, 2013-004525-84, CT-P6 3.2


This study will determine whether CT-P6 and Herceptin are equivalent in patients with early-stage breast cancer undergoing neoadjuvant chemotherapy. Our hypothesis is that the pathologic complete response rate will be equivalent in patients treated with neoadjuvant CT-P6 or Herceptin. Patients will receive 8 cycles of neoadjuvant systemic therapy and up to 10 cycles of therapy in the adjuvant setting.

(Active Comparator)
trastuzumab Herceptin
Trastuzumab 6mg/kg is ongoing to be administered for both arms after 8mg/kg loading dose.

Primary Outcomes

Equivalence to Herceptin as determined by pCR (pathological Complete Response)
time frame: After Neo-adjuvant therapy and Surgery (up to 30 weeks)

Eligibility Criteria

Female participants at least 18 years old.

Inclusion Criteria: - Patient who has histologically confirmed and newly diagnosed breast cancer - Patient who has clinical stage I, II, or IIIa operable breast cancer according to AJCC (American Joint Committee on Cancer) Breast Cancer Staging 7th edition - Patient who has HER2-positive status confirmed locally, defined as 3+ score by IHC (immuno-histochemistry). Exclusion Criteria: - Patient who has bilateral breast cancer - Patient who has received prior treatment for breast cancer, including chemotherapy, biologic therapy, hormone therapy, immunotherapy, radiation or surgery, including any prior therapy with anthracyclines.
