Measure
Upfront Breast Surgery
Patients will have the microdevice implanted prior to breast surgery, in the absence of neoadjuvant chemotherapy KIBUR MICRODEVICE: This device contains 16 reservoirs, each with a unique single agent or drug combination in microdose amounts of less than one millionth of a systemic patient dose. The device is implanted directly into the tumor during a biopsy procedure, and remains in situ for \~24 hours.
Neoadjuvant Therapy
Patients will have the device placed and retrieved on a core biopsy the following day, then receive neoadjuvant chemotherapy prior to definitive breast surgery. KIBUR MICRODEVICE: This device contains 16 reservoirs, each with a unique single agent or drug combination in microdose amounts of less than one millionth of a systemic patient dose. The device is implanted directly into the tumor during a biopsy procedure, and remains in situ for \~24 hours. anthracycline and taxane based chemotherapy: Conventional, standard of care neoadjuvant chemotherapy delivered irrespective of device readout
