This study is currently recruiting participants.
Verified July 2013 by Hoffmann-La Roche
Sponsor:
Hoffmann-La Roche
Collaborators:
National Surgical Adjuvant Breast and Bowel Project (NSABP)
German Breast Group
Information provided by (Responsible Party):

History of Changes


Purpose 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.


Condition Intervention Phase Breast Cancer
Drug: trastuzumab emtansine
Drug: trastuzumab
Phase 3

Study Type: Interventional Study Design: Allocation: Randomized
Endpoint Classification: Safety/Efficacy Study
Intervention Model: Parallel Assignment
Masking: Open Label
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:

  • 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 ] [ Designated as safety issue: No ]
  • Overall survival: Time from randomization to death of any cause [ Time Frame: up to 10 years ] [ Designated as safety issue: No ]
  • Distant recurrence-free interval: Time from randomization to date of distant breast cancer recurrence [ Time Frame: up to 10 years ] [ Designated as safety issue: No ]
  • Safety: Incidence of adverse events [ Time Frame: up to 10 years ] [ Designated as safety issue: No ]
  • Incidence of cardiac events: Death from cardiac cause or severe chronic heart failure (NYHA Class III or IV) [ Time Frame: up to 10 years ] [ Designated as safety issue: No ]
  • 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 ] [ Designated as safety issue: No ]


Estimated Enrollment: 1484 Study Start Date: April 2013 Estimated Study Completion Date: March 2023 Estimated Primary Completion Date: March 2023 (Final data collection date for primary outcome measure)
Arms Assigned Interventions Experimental: Trastuzumab emtansine Drug: trastuzumab emtansine 3.6 mg/kg intravenously every 3 weeks, 14 cycles
Active Comparator: Trastuzumab Drug: trastuzumab 6 mg/kg intravenously every 3 weeks, 14 cycles

Re: TDM1 trial (KATHERINE) Phase III

Mister Sister,

You are not eligible because you did adjuvant chemo - after your mastectomy.

This is for neoadjuvant, before surgeries.

A nice vaccine trial might be good.

Re: TDM1 trial (KATHERINE) Phase III

SISTER!! I read TOO far into this...it was late...looking for ALL I can find to KICK this...

Actually, when I had my first consult with my MO, he asked his "fellow" to see if there were any clinical studies available...!!

Tomorrow, I have an echo, along with the beginnning of my first Herceptin...or to complete my year of herceptin, praying my EF holds up, and my body doesn't reject Herceptin along the road...

I "check" on your studies... "
