E.2.3 | Trial contains a sub-study | Yes |
E.2.3.1 | Full title, date and version of each sub-study and their related objectives |
Genetic Markers from peripheral blood to predict tumor biology, treatment response and prognosis |
|
E.3 | Principal inclusion criteria |
1. Written informed consent for all study according to local regulatory requirements prior to beginning specific protocol procedures.
2. Complete baseline documentation must be sent to GBG Forschungs GmbH.
3. Unilateral or bilateral primary carcinoma of the breast, confirmed histologically by core biopsy. Fine-needle aspiration alone is not sufficient. Incisional biopsy is not allowed. In case of bilateral cancer, the investigator has to decide prospectively which side will be evaluated for the primary endpoint.
4. Tumor lesion in the breast or the nodes must be measurable in two dimensions, preferably by sonography. In case of inflammatory disease, the extent of inflammation can be used as measurable lesion.
5. Patients must be in the following stages of disease:
- cT1b - cT4a-d irrespective of nodal involvement.
In patients with multifocal or multicentric breast cancer, the largest lesion should be measured.
6. Triple negative disease with centrally confirmed ER negative/PR negative/HER-2 negative, and centrally confirmed Ki-67 value. ER negative is defined as <1%, PR negative is defined as <10% stained cells and HER2-negative is defined as either IHC 0/1+ or IHC 2+ and in-situ hybridisation (ISH) of either ratio <2.0 or less than 6 copies of HER2 per tumor cell. Stromal TILs will be evaluated in three groups: low immune infiltrate (0-10% stromal TILs), intermediate immune infiltrate (11-59% stromal TILs), LPBC 60-100% stromal TILs. PD-L1 status and other predefined markers will be prospectively assessed during the study. Formalin-fixed, paraffin-embedded (FFPE) breast tissue from core biopsy has therefore to be sent to the GBG central pathology laboratory prior to randomization.
7. Age 18 years.
8. ECOG Performance status 0-1.
9. Normal cardiac function must be confirmed by ECG and cardiac ultrasound (LVEF or shortening fraction) within 3 months prior to randomization. Results must be above the normal limit of the institution.

Thyroid function
- FT3 within local laboratory normal range
- FT4 within local laboratory normal range
- TSH within local laboratory normal range
11. Negative pregnancy test (urine or serum) within 14 days prior to randomization for all women of childbearing potential. Female subjects must either be of non-reproductive potential (ie, post-menopausal by history: ≥60 years old and no menses for ≥1 year without an alternative medical cause; OR history of hysterectomy, OR history of bilateral tubal ligation, OR history of bilateral oophorectomy) or must have a negative serum pregnancy test upon study entry.
12. Complete staging work-up within 3 months prior to randomization. All patients must have had breast imaging by breast ultrasound plus either bilateral mammography or breast MRI (one of those ≤21 day). All patients must have had chest X-ray (PA and lateral), abdominal ultrasound or CT scan or MRI, and bone scan (according to guidelines). In case of positive bone scan, bone X-ray is mandatory. Other tests may be performed as clinically indicated.
13. Patients must be available and compliant for central diagnostics, treatment and follow-up.

E.4 | Principal exclusion criteria |
1. Prior chemotherapy for any malignancy.
2. Prior radiation therapy for breast cancer.
3. Pregnant or lactating patients. Patients of childbearing potential must implement adequate non-hormonal contraceptive measures (barrier methods, intrauterine contraceptive devices, sterilization) during study treatment.

E.5 End points |
E.5.1 | Primary end point(s) |
Pathological complete response of breast and lymph nodes (ypT0 ypN0; primary endpoint) is defined as no microscopic evidence of residual invasive and no non-invasive viable tumor cells in all resected specimens of the breast and axilla.
Pathological response will be assessed considering all removed breast and lymphatic tissues from all surgeries.
Patients with negative sentinel node biopsy prior to treatment start and no axilla surgery after neoadjuvant chemotherapy will be counted as pCR if no invasive and non-invasive residual tumor is detected in the removed breast tissue. Patients with histologically/cytologically positive nodes prior to treatment start and no axilla surgery after chemotherapy will be counted as no pCR (preferably axillary dissection instead of sentinel node biopsy is strongly recommended in this situation). Patients with positive sentinel node biopsy prior to treatment start and no invasive and non-invasive residual tumor detected in the removed breast tissue and lymph nodes after chemotherapy will be counted as pCR. |
|
E.5.1.1 | Timepoint(s) of evaluation of this end point |
Pathological response will be assessed considering all removed breast and lymphatic tissues from all surgeries. pCR rate will be assessed approximately 25 weeks after randomization. |
|
E.5.2 | Secondary end point(s) |
ypT0/is ypN0 is defined as no microscopic evidence of residual invasive viable tumor cells in all resected specimens of the breast and axilla; in case of sentinel node biopsy prior to treatment start, the axillary lymph nodes will be evaluated as described for the primary endpoint.
ypT0 ypN0/+ is defined as no microscopic evidence of residual invasive or non-invasive viable tumor cells in all resected specimens of the breast;
ypT0/is ypN0/+ is defined as no microscopic evidence of residual invasive viable tumor cells in all resected specimens of the breast; patients with a sentinel node biopsy prior to treatment start will be evaluated for ypT(any) ypN0 similarly to the description given for the primary endpoint.
Clinical (c) and imaging (i) response will be assessed after part 2 of the study and before surgery by physical examination and imaging tests. Sonography is the preferred examination, however, if sonography appears not to provide valid results or is not performed, other imaging tests will be considered with the following priority: MRI, mammography, computed tomogram. The same imaging method should be considered for the measurement before, during and after treatment.
Breast conservation is defined as tumorectomy, segmentectomy or quadrantectomy as a most radical surgery.
Tolerability and Safety: Descriptive statistics for the 2 treatments will be given on the number of patients whose treatment had to be reduced, delayed or permanently stopped. The reason for termination includes aspects of efficacy (e.g. termination due to tumor progression), safety (e.g. termination due to adverse events) and compliance (e.g. termination due to patient's withdrawal of consent). Reasons for premature termination will be categorized according to the main reason and will be presented in frequency tables. Safety by toxicity grades is defined by the NCI-CTCAE version 4.0.
Quality of life: the two treatment arms will be compared descriptively concerning important side effects of taxane therapy and their impact on QoL described by the patient.
Correlative science research: Predefined and other exploratory analyses will be performed to identify possible relationships between biomarkers and drug activity. The aim is to identify potential predictive parameters (pCR, no treatment effect (according to regression score 0-1), RFS, EFS (per FDA definition) and OS). Missing data on response evaluation will be set to no response.
