Precision Optical Guidance for Oral Biopsy Based on Next-Generation Hallmarks of Cancer (1R01DE029590-01): A Clinical Study to Evaluate and Optimize the Technical Performance Characteristics of an Active Biopsy Guidance System

NCT ID: NCT05554133Sponsor: M.D. Anderson Cancer CenterLast updated: 2026-04-16

Summary

To learn if a new type of imaging device called the Active Biopsy Guidance System can help doctors to decide when and where to perform invasive biopsies of mouth lesions.

Detailed description

Primary objective: -To evaluate and optimize the technical performance characteristics of an Active Biopsy Guidance System. Secondary objective: -To provide a preliminary estimate of the sensitivity and specificity of the Active Biopsy Guidance System with respect to histopathology. Optical imaging; optical projection of light onto tissue; optical contrast agent (proflavine).

Arms & interventions

DeviceHigh Resolution Microendoscope (HRME)
The High Resolution Microendoscope (HRME) take pictures of a very small area of the lining of the mouth, about the size of a pencil tip, but at high magnification.
DeviceOptical Mapping Scope
The optical mapping scope displays a wide area of the lining of the mouth (about the size of the top of a soda can) by shining different colors of light into the mouth and taking pictures.
DrugProflavine hemisulfate
A coloring substance (a fluorescent dye which glows green in the dark), called proflavine hemisulfate, will be painted on areas of the mouth with a cotton tip applicator to help improve the pictures

Outcome measures

Primary

To establish a preliminary estimate of the sensitivity and specificity of the Active Biopsy Guidance System with respect to histopathology
Time frame: Through study completion an average of 1 year.
