This study will evaluate the safety, tolerability, and efficacy of Bevonescein (ALM-488) administered as an intravenous (IV) infusion to patients undergoing head \& neck surgery. The study will also characterize the pharmacokinetics of Bevonescein (ALM-488) in this subject population and determine the dose of Bevonescein (ALM-488) needed to generate a fluorescence signal in nerve tissue to enable fluorescence recordings and image analysis with an imaging system. The study will also evaluate the effect of timing of Bevonescein (ALM-488) administration, relative to surgery, on fluorescence characteristics.
