Clinical Trial Summary

This is a single centre Window-of-Opportunity trial investigating the efficacy and feasibility of short term imatinib in patients with newly diagnosed triple negative breast cancer (TNBC) planned for surgery, with tumours ≥ 15 mm, any status in the axilla when neoadjuvant treatment not is considered as an option. The primary aim is to determine the proportion of patients that converts to estrogen receptor (ER) positive breast cancer in the removed breast cancer tissue at surgery.


Description:

This is a single centre Window-of-Opportunity trial that will investigate the efficacy and feasibility of short term (10 days) imatinib in patients with newly diagnosed TNBC planned for surgery, with tumours ≥ 15 mm, any status in the axilla and when neoadjuvant treatment not is considered as an option. Imatinib is given at a dose of 400 mg daily. The primary aim is to determine the proportion of patients that converts to ER positive breast cancer in the removed breast cancer tissue at surgery. The secondary aim is to evaluate the safety and adverse events (AE) will be collected throughout the study, from informed consent until 30 days after the last dose of the IMP imatinib. AEs will be graded according to National Cancer Institute (NCI) Common Terminology Criteria for Adverse Events (CTCAE) version 5.0.
