E.5 End points |
E.5.1 | Primary end point(s) |
ER-positivity at surgery after pre-treatment with imatinib [time frame from base-line to surgery]. ER is assessed according to the international guide-lines and by gene expression profiles. |
|
E.5.1.1 | Timepoint(s) of evaluation of this end point |
From base-line biopsy to surgery [2 weeks] |
|
E.5.2 | Secondary end point(s) |
Toxicity and safety of short term exposure to imatinib [time frame 6 weeks] Side effects are assessed and graded according to the National Cancer Institute CTCAE version 5.
Exploratory analyses (gene expression profiles including intrinsic subtypes, immune response, proliferation) in relation to proportion of patients in whom tumours are successfully converted to oestrogen dependent breast cancer. |
|
E.5.2.1 | Timepoint(s) of evaluation of this end point |
Toxicity - from first dose of imatinib to 30 days after the last dose of imatinib [time frame 6 weeks].
Exploratory analyses: Laboratory analyses will be completed within 6 months from the last dose of imatinib for the last included patient. |
