Optiscan Imaging (ASX:OIL) said 25 of the target 50 patients were imaged in its first in-human breast cancer imaging study at Royal Melbourne Hospital in Victoria, reaching a halfway mark milestone, according to a Thursday Australian bourse filing.
The study is assessing surgical margins in breast cancer patients undergoing lumpectomy procedures using the InVue precision surgery imaging device for in vivo imaging and the InForm digital pathology imaging device for ex vivo imaging, per the filing.
InVue is used intraoperatively in the resection cavity to generate live in vivo images immediately after tumor removal, while InForm is used to analyze the excised tissue.
Clinical readouts of the analyzed cases to date show nine with clear margins, four with narrowly clear margins, and five with involved margins, the company said. There were no reported adverse events related to intravenous sodium fluorescein contrast agent injections.
The study was expanded to a second clinical site to accelerate recruitment.
