Study information
Scientific title
ARTiST: Aromasin® Randomised TrIal +/- Sutent® as neoadjuvant Therapy for post-menopausal women with breast cancer
Acronym
ARTiST
Study hypothesis
Angiogenesis is important for the growth of all cancers and there is emerging evidence that angiogenesis inhibitors will be an important therapeutic option in breast cancers. The multi-targeted signal transduction inhibitor sunitinib has shown efficacy in advanced disease. Exemestane is a steroidal aromatase inhibitor commonly used.
Hypothesis: Simultaneous blockage of two important pathways will lead to a superior clinical response.

Condition
Breast cancer
Intervention
The participants will be randomly allocated to the following two arms (randomisation ratio 1:1):
Arm A: Exemestane (Aromasin®) (oral) 25 mg/day for 18 weeks
Arm B: Exemestane (Aromasin®) (oral) 25 mg/day for 18 weeks + sunitinib (Sutent®) (oral) 37.5 mg/day for weeks 1 to 16, followed by a 2-week break before surgery
Intervention type
Drug
Phase
Phase II
Drug names
Exemestane (Aromasin®), sunitinib (Sutent®)
Primary outcome measures
Ki67 response to therapy. Assessed by biopsy analysis pre-, during (week 3) and post-treatment (week 18)
Secondary outcome measures
1. Clinical response rate (cRR), assessed by clinical examination at weeks 3, 9 and 17
2. Radiological response rate (rRR), assessed by US scan at weeks 3, 9 and 17
3. Clinical/radiological response among patients over-expressing EGFR/HER-2, assessed by US scan/clinical examination at weeks 3, 9 and 17
4. Complete pathological response (pCR), assessed from the tumour tissue removed at surgery
5. Circulatory endothelial cells (CEC) and circulatory endothelial progenitor (CEP) levels, assessed by blood sample pre-, during (week 3) and post-treatment (week 18)
6. Analysis of candidate genes and global gene expression profiling to identify molecular markers of response or resistance. Assessed by biopsy analysis pre-, during (week 3) and post-treatment (week 18)
7. Disease free and overall survival. After surgery, patients will have a hospital visit every 6 months for 5 years
