Studien-Informationen

Detailed Description:

Dual targeting of HER2 with trastuzumab and pertuzumab in HER2-positive breast cancer is linked to clinical evidence of reversal of initial resistance to trastuzumab (Baselga J et al, J Clin Oncol 2010) in cases progressing on trastuzumab therapy, and in dramatic improvement in progression free and overall survival when the two monoclonal antibodies are used in combination with docetaxel (THP regimen) as first line therapy of metastatic disease as shown in the CLEOPATRA study (Swain S et al, ESMO abstract 2014). The randomized NeoSphere study showed that the same THP regimen given for 4 cycles as neoadjuvant treatment increased the rate of pathologic complete response (pCR) over that with conventional docetaxel and trastuzumab or docetaxel and pertuzumab (Gianni L et al, Lancet Oncol 2012).

Encouraging clinical data emerging in the field of tumor immunotherapy have demonstrated that therapies focused on enhancing T cell responses against cancer can result in a significant survival benefit in patients with advanced malignancies (Hodi FS and Dranoff G, J Cutan Pathol 2010; Kantoff PW et al, New Engl J Med 2010; Chen DS et al, Clin Cancer Res 2012). Many human tumors have been found to overexpress PD L1, which acts to suppress anti tumor immunity. PD 1 is an inhibitory receptor expressed on T cells following T cell activation, which is sustained in states of chronic stimulation, such as in chronic infection or canc Atezolizumab is a human monoclonal antibody containing an engineered Fc-domain to optimize efficacy and safety that targets PD-L1 and blocks binding of its receptors, including PD-1 and B7.1.

In addition to being involved in the natural progression of cancer, immunity can affect the activity of various anticancer agents. Accordingly, recent evidence suggests that some chemotherapeutic drugs, such as anthracyclines and oxaliplatin, rely on the induction of anticancer immune responses. Immune responses also play a major role in the efficacy of targeted therapies with monoclonal antibodies (Stagg J et al, Breast Care 2012). Studies have shown monoclonal antibodies such as trastuzumab and rituximab rely in part on immunemediated killing through antibody-dependent cellular cytotoxicity (ADCC). While innate immune responses appear to be important for tumor antigen-targeted monoclonal antibody therapies, recent studies in mice and correlative clinical evidence suggest that trastuzumab may also stimulate adaptive antitumor immunity. These studies raise the possibility that combination strategies may be used to capitalize on the adaptive tumor-specific immunity generated by anti-HER2 monoclonal antibodies.

Based on these considerations, we plan to conduct a randomized neoadjuvant study of the combination of trastuzumab, pertuzumab, carboplatin and paclitaxel with or without atezolizumab in women with early high-risk and locally advanced HER2-positive suitable for neoadjuvant therapy. One study arm will also include anthracycline and cyclophosphamide.
 

Ein-/Ausschlusskriterien

Inclusion Criteria:

1. Female patients aged 18 years or older with early high-risk ((T1cN1; T2N1; T3N0) or locally advanced and inflammatory breast cancers (stage III A-C according to AJCC) suitable for neoadjuvant treatment

2. Histologically confirmed unilateral invasive breast cancer

3. HER2 positive disease according to ASCO/CAP guidelines 2013 [defined as IHC 3+ or ISH positive (by gene copy number or HER2 gene/CEP17 ratio of 2 or greater)]

4. Known estrogen (ER) and progesterone receptor (PgR)

5. Availability of a representative paraffin-embedded (FFPE) tumor block taken at diagnostic biopsy for central confirmation of HER2 eligibility, for assessment of ER, PgR, Ki67 and PD-L1 expression and for biomarker evaluation is mandatory. Note: the diagnostic biopsy of the breast lesion may have been taken before the required screening procedures. If diagnostic sentinel node biopsy if performed, an FFPE block must be available. An FFPE tumor block is also mandatory after the first cycle of therapy. Surgery tissue (residual tumor or tumor bed in case of pCR and axillary node material) is also mandatory.

6. Consent to the collection of blood samples mandatorily before starting neoadjuvant treatment, after the first cycle of therapy, at the end of neoadjuvant treatment (before surgery), 6 months after surgery and at the end of all treatments.

7. ECOG performance status 0 or 1

8. For women who are not postmenopausal (≥ 12 months of non-therapy-induced amenorrhea) or surgically sterile (absence of ovaries and/or uterus): agreement to remain abstinent or use single or combined contraceptive methods that result in a failure rate of < 1% per year during the treatment period and for at least 6 months after the last dose of study drugs. Abstinence is only acceptable if it is in line with the preferred and usual lifestyle of the patient. Periodic abstinence (e.g., calendar, ovulation, symptothermal, or postovulation methods) and withdrawal are not acceptable methods of contraception. Examples of contraceptive methods with a failure rate of < 1% per year include tubal ligation, male sterilization, hormonal implants, established, proper use of combined oral or injected hormonal contraceptives, and certain intrauterine devices. Alternatively, two methods (e.g., two barrier methods such as a condom and a cervical cap) may be combined to achieve a failure rate of < 1% per year. Barrier methods must always be supplemented with the use of a spermicide

9. Written informed consent to participate in the trial (approved by the Institutional Review Board [IRB]/ Independent Ethics Committee [IEC]) obtained prior to any study specific screening procedures
