A Dye for the Detection of Cancer of the Tongue and Mouth

February 10, 2026 updated by: Memorial Sloan Kettering Cancer Center

A Phase I/II Study of the Fluorescent PARP1 Binding Imaging Agent PARPi-FL in Patients With Oral Squamous Cell Carcinomas

The purpose of this study is to test if an investigational dye, called PARPi-FL, can be used to detect this type of cancer. This will be the first time that PARPi-FL is being tried in people. First, the investigators will test the safety of PARPi-FL at different doses to find out what effects, if any, it has on people. The investigators will also see which amount of PARPi-FL is best suited to detect cancers of the mouth and tongue.

Arms and Interventions

Participant Group / Arm
Intervention / Treatment
Experimental: Fluorescent PARPi Binding Imaging Agent PARPi-FL
In the phase I of the study, increasing concentrations of PARPi-FL will be used in up to 12 patients with OSCC to determine concentration that results in the highest contrast between tumor and normal mucosa. Dose escalation will be performed in groups of three patients until image contrast decreases, side effects are noted or the concentration of PARPi-FL exceeds 1μM. Imaging will be performed in the Department of Surgery during a presurgical visit including clinical examination of the oral cavity. In the phase II part of the study the concentration of PARPi-FL determined in phase I will be used to image 18 patients with OSCC on the day of surgery. Imaging findings will be correlated with histopathologic findings in the surgically resected specimens.
Drug: Olaparib
For PARRi-FL, imaging patients will first gargle a solution of PARRi-FL for 1 min, then spit out this solution and gargle with a cleaning solution (the solvent used for PARRi-FL) for 1 min. Then fluorescence imaging of the oral cavity and pharynx will be performed with an endoscope. The intensity and extent of the fluorescence signal will be recorded by one of the investigators for the tumor and adjacent normal mucosa.
