Brief Summary:

T-DM1 , which is a highly innovative but also expensive antiHER2 agent consisting in the coupling of the humanised monoclonal antibody trastuzumab with a cytotoxic agent (maytansine derivate) has shown an encouraging antitumor activity evaluated by Recist criteria (35% objective response rate, 44% stable disease, 18% progressive disease) in patients with advanced HER2 positive Breast Cancer pretreated with several cytotoxic drugs, trastuzumab and lapatinib.

Rationale I :For TDM1 to be active, the presence of an intact HER2 receptor is "key" since the internalization of the cytotoxic moiety depends on the binding of trastuzumab to the external domain of HER2.

The zirconium 89 labelled trastuzumab PET/CT (or HER2 immunoPET/CT) is a non invasive test which shows promise in measuring HER2 expression (extracellular domain) for the entire disease burden and which could identify non responding patients prior to TDM1 administration.

Rationale II: As for many such agents, it is desirable to identify early on (here with the use of FDG-PET/CT) which patients are unlikely to benefit from the therapy

Condition or disease Intervention/treatment Phase
HER-2 Positive Breast Cancer Drug: T-DM1 Procedure: 89Zr-trastuzumab Phase 2

Detailed Description:

The main objective of the trial is to prospectively evaluate the ability of a zirconium 89 labelled trastuzumab PET, to predict, before initiation of the treatment, treatment failure to a new targeted drug: T-DM1.

At the same time, the early FDG-PET/CT, performed after 1 course of T-DM1, will also evaluated for its ability to predict non response to TDM1.

Arm Intervention/treatment
After an imaging phase, the patient will receive T-DM1 iv every 3 weeks until progression or toxicity
Drug: T-DM1
3.6 mg/kg iv every 3 weeks
Other Name: Trastuzumab-DM1

Procedure: 89Zr-trastuzumab
Injection of 89Zr-trastuzumab for HER2 imaging
Other Name: Zirconium 89 labelled trastuzumab

Primary Outcome Measures :
  1. negative predictive value of the 89Zr-trastuzumab PET/CT [ Time Frame: 2 years ]
    The primary objective is to show that pre-treatment 89Zr-trastuzumab PET/CT is able to select lesions not responding morphologically from treatment with T-DM1 (applying RECIST 1.0 criteria).

Secondary Outcome Measures :
  1. negative predictive value of the early FDG PET/CT [ Time Frame: 2 years ]
    The first secondary objective is to show that early FDG PET/CT (performed after one cycle of T-DM1 just before the second cycle) is able to select lesions not responding from treatment with T-DM1 according to metabolic and morphological response criteria post 3 cycles of T-DM1.

  2. negative predictive value of the 89Zr-trastuzumab PET/CT [ Time Frame: 2 years ]
    The second secondary objective is to show that 89Zr-trastuzumab PET/CT is able to select lesions not responding from treatment with T-DM1 according to metabolic response criteria post 3 cycles of T-DM1.

  3. negative predictive value of the combined 89Zr-trastuzumab PET/CT and early PET/CT [ Time Frame: 2 years ]
    The third secondary objective is to show that a lesion with no/faint uptake on 89Zr-trastuzumab PET/CT and not responding metabolically on the early FDG-PET/CT will not respond according to metabolic and morphological criteria after 3 cycles of T-DM1.

Layout table for eligibility information
Ages Eligible for Study:   18 Years and older   (Adult, Older Adult)
Sexes Eligible for Study:   All
Accepts Healthy Volunteers:   No

Inclusion Criteria:

  1. The patient must have histologically confirmed HER2 positive invasive carcinoma of the breast in the reference laboratory of the participating center. HER2 positive criteria to be applied are those used in the participating countries:

    • Belgium: FISH amplification ratio ≥ 2 in the reference laboratory of the participating center
    • The Netherlands: IHC 3+ or FISH ratio ≥ 2 in the reference laboratory of the participating center
  2. The patient must have documented progressive disease and present with at least 2 non-bone "target" metastatic lesions, unequivocally of neoplastic origin with

    • a transaxial diameter greater than 2 cm on the screening diagnostic CT/MRI for all non-bone lesions except lymphnodes
    • a short axis greater than 1,5 cm for lymphnodes on the screening diagnostic CT/MRI These two lesions should not be confluent with adjacent lesions and not have been irradiated previously.
  3. A concurrent biopsy of a metastatic site is mandatory (with two formalin fixed paraffin embedded (FFPE) core sample and two snap frozen tumor sample) after progression has been documented and before inclusion and the patient agrees with the procedure.
  4. Primary tumor blocks (or 11 unstained slides) available for confirmatory central laboratory HER2 testing in Institut Jules Bordet. If available, a snap frozen sample of the primary tumor will also be centralized in Institut Jules Bordet.
  5. Age ≥ 18 years
  6. Eastern Cooperative Oncology Group (ECOG) performance status (PS) 0 to 1
  7. No significant cardiac history and current LVEF ≥ 50%
