Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

This phase I/II trial studies the side effects of tozuleristide in imaging oral cavity squamous cell cancer and high-grade oral cavity dysplasia during surgery. Tozuleristide is an imaging agent that specifically binds to tumor cells. When exposed to near-infrared light, tozuleristide causes tumor cells to fluoresce (light up), so that surgeons may better distinguish tumor cells from healthy cells during surgery.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

OUTLINE:

Beginning 1 hour before surgery, patients receive tozuleristide intravenously (IV) over 1-5 minutes. Patients then surgical resection per standard of care and undergo near infrared (NIR) imaging with standard of care device.

Eligibility Criteria

Check the participation requirements, including inclusion and exclusion rules, age limits, and whether healthy volunteers are accepted.

Inclusion Criteria

* Adult subjects age \>= 18 years (yr)
* Subjects must have suspected or confirmed oral cavity dysplasia or cT1-4 squamous cell carcinoma for which surgical excision is deemed clinically indicated by the treating physician. Histology confirmation not required prior to surgery
* Able to provide written informed consent
* If of child-bearing potential, agree to the continued use of 2 reliable forms of contraception from study enrollment through 30 days after receiving the study product. Male subjects must agree to use 2 reliable methods of contraception simultaneously for 30 days after receiving the study product if their partner is of child-bearing potential
* Available for all study visits and able to comply with all study requirements

Exclusion Criteria

* Known or suspected sensitivity to indocyanine green

* Any current medications with the potential to generate fluorescence or photochemical reaction
* Enrolled in any other ongoing study
* Currently lactating or breastfeeding
* Positive pregnancy test or planning to become pregnant within 30 days (d) of receiving tozuleristide
* Any current condition, including psychological and social situations which, in the opinion of the investigator, would impact adversely on the subject or the interpretation of the study data
