What was measured

Sensitivity of LUM Imaging System on cancer was calculated as percentage of tissues with cancer that was removed from lumpectomy cavity due to positive detection by LUM Imaging System. The estimates of the instrument diagnostic sensitivity used Generalized Estimating Equations (GEE) approach. This method was used to analyze correlated data which was modeled with generalized linear model having binomial link function and including correlation cluster and matrix information (here within each subject). LUM Imaging System was used during the surgery, but the assessment of the outcomes was unknown until the pathology report was available.

Analysis population: modified intent to treat population (mITT) includes subjects injected with LUM015 and LUM Imaging was performed

Groups in this outcome

Device Intervention: LUM Imaging System Used During Surgery

The LUM Imaging Device was used to examine inside the lumpectomy cavity to determine if the dye indicated any areas that might contain residual tumor. If the imaging tested positive for the cancer cells remaining in the lumpectomy cavity, the surgeon would remove an additional piece of tissue. This process was continued until a negative reading from the device was obtained or a maximum of 2 shaves of additional tissue had been removed. Patients in this arm received the study drug, LUM015. Study Device Arm: LUM015 was administered 2 to 6 hours prior to surgery. The LUM Imaging device was used to assist in the removal of additional tumor tissue.
