Brief summary

The purposes of the research trial are to study the safety of ABY-029 and to understand how much of the drug is needed to reach head and neck squamous cell carcinomas (HNSCC) so it can be visualized best by surgeons. Investigators will do this by comparing two groups of participants that receive different, very small amounts of ABY-029. Investigators will use an imaging system during surgery to record the amount of ABY-029 in the participant's tumor and in the surrounding tissue.

Interventions

ABY-029 will be administered via single intravenous injection to subjects with HNSCC approximately 1-3 hours prior to surgery. All research procedures will occur during surgery. The research procedures involve image and measurement data collection and biopsy specimen sampling. Research data collection will occur at 3 or 4 time points during surgery using either standard-of-care tools and methods or non-significant risk experimental devices. No follow-up visit will be required of participants. Participants will be monitored for possible adverse events for approximately 30 days by the operating surgeon involved in the clinical trial procedures and through review of participant medical records.

Design outcomes

Primary

MeasureTime frameDescription
Adverse events related to ABY-029one monthTo study the safety of ABY-029, adverse events related to 6X and 10X doses of ABY-029 will be tracked following surgery, and the proportion of study-drug related adverse events at 6X and 10X doses will be compared statistically for significant differences.
Diagnostic accuracy of measured ABY-029 fluorescence ex-vivo in surgical specimensup to three monthsTo measure the diagnostic performance of ABY-029, the diagnostic accuracy of measured ABY-029 fluorescence ex-vivo in surgical specimens histologically confirmed as tumor from participants receiving the 6X microdose and 10X microdose.
