Brief summary

This single arm study will assess the efficacy and safety of a combination of Avastin and docetaxel following cyclophosphamide and doxorubicin, in patients with HER2 negative operable breast cancer. Patients will receive 4 x 3 week cycles of chemotherapy with doxorubicin (60mg/m2 iv on day 1 of each cycle) and cyclophosphamide (600mg/m2 iv on day 1 of each cycle). They will then receive 4 x 3 week cycles of docetaxel (75mg/m2 on day 1 of each cycle) in combination with Avastin (15mg/kg on day 1 of each cycle). The anticipated time on study treatment is 3-12 months, and the target sample size is \<100 individuals.

MeasureTime frameDescription
Percentage of Participants With Pathological Complete Response (pCR)After Week 24 (surgery)The percentage of participants with pCR was determined by anatomopathological study after completion of 8 cycles of study treatment. The anatomopathological study of the surgical piece was performed and assessed according to the Miller-Payne criteria: 1) the primary tumor was Grade 5 (no malignant cells identified at the location of the primary tumor (ductal carcinoma in situ may be present); 2) no involvement was identified in the lymph nodes; 3) the tumour size at evaluation of the surgical piece was 0 centimeters (cm); and 4) the pathological staging of the tumour from the surgical piece was pT0pN0pM0, the stage is not applicable (NA). It will only be considered pCR in the case of absence of invasive tumour cells in the breast and lymph nodes.

MeasureTime frameDescription
Percentage of Participants With Objective Clinical ResponseWithin 28 days of enrollment, Weeks 12 and 24Overall clinical response is the best response obtained through physical examination and/or radiological tests after completion of chemotherapy cycles.

Percentage of Participants With pCR by Proliferation of Ki67

The percentage of participants with pCR was determined by anatomopathological study after completion of 8 cycles of study treatment. The anatomopathological study of the surgical piece was performed and assessed according to the Miller-Payne criteria. It was only considered pCR in the case of absence of invasive tumour cells in the breast and lymph nodes. Biomarker Ki67 proliferation was defined as low (less than \[\<\]15% ) and high (≥15%).

Time frame: After Week 24 (surgery)

Population: Population evaluable for anatomopathological response with evaluable levels of the specified biomarker; data were missing for 2 participants.

Percentage of Participants With pCR by RKISS1 Gene Expression

The percentage of participants with pCR was determined by anatomopathological study after completion of 8 cycles of study treatment. The anatomopathological study of the surgical piece was performed and assessed according to the Miller-Payne criteria. It was only considered pCR in the case of absence of invasive tumour cells in the breast and lymph nodes. RKISS1 gene expression was defined as below the housekeeping reference level (\>0), above the housekeeping reference level (\<0), or equal to the housekeeping reference level (0).

Percentage of Participants With pCR by Vascular Endothelial Growth Factor Receptor (VEGFR) Amplification

The percentage of participants with pCR was determined by anatomopathological study after completion of 8 cycles of study treatment. The anatomopathological study of the surgical piece was performed and assessed according to the Miller-Payne criteria. It was only considered pCR in the case of absence of invasive tumour cells in the breast and lymph nodes. VEFGR amplification was defined as 1 (aneuploid), 2 (normal), 4 (amplification), or NE (not evaluated).
