A Study of Avastin (Bevacizumab) and Sequential Chemotherapy in Patients With Primary HER2 Negative Operable Breast Cancer.

5 november 2014 bijgewerkt door: Hoffmann-La Roche

An Open Label Study to Assess the Effect of a Combination of Avastin and Docetaxel and Sequential Chemotherapy on Pathological Response in Patients With Primary Operable HER2 Negative Breast Cancer

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.

Maatregel Beschrijving
Tijdsspanne
Percentage of Participants With Pathological Complete Response (pCR)
Tijdsspanne: 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.
After Week 24 (surgery)

Tijdsspanne
Percentage of Participants With Objective Clinical Response
Tijdsspanne: Within 28 days of enrollment, Weeks 12 and 24
Overall clinical response is the best response obtained through physical examination and/or radiological tests after completion of chemotherapy cycles. The percentage of participants with objective response based on assessment of complete response (CR) or partial response (PR) according to Response Evaluation Criteria in Solid Tumors (RECIST) and was categorized as clinical response (CR+PR) or clinical benefit (CR+PR+ no change [NC]). Per RECIST, CR was defined as disappearance of all target lesions, non-target lesions, and normalization of tumor marker level. PR was defined as greater than or equal to (≥)30 percent (%) decrease under baseline of the sum of the longest diameter (LD) of all target lesions. No unequivocal progression of non-target disease. No new lesions. Complete and partial responses must have been confirmed no less than 4 weeks after the criteria for response were first met.
