Brief Summary
The primary end-point of the study is to determine the specificity and sensitivity of OTL38 in identifying pituitary adenomas when excited by an imaging probe. The investigators intend to enroll 50 patients in this study. The study is focusing on patients presenting with suspected pituitary adenomas who are considered to be good surgical candidates.

Conditions
Outcome Measures
Primary Outcomes (2)
Detection of OTL38 in tumor tissue.
The detection of OTL38 uptake by tumor tissue will be made with the use of an imaging system that detects the presence of dye in tissue.
60 months
Evaluate the ability of OTL38 to discern between tumorous tissue and normal, neural tissue.
Specificity and sensitivity of OTL38 will be calculated through the comparison of the video images gathered from the imaging system and the final pathology results from the surgical procedure.
60 months
Secondary Outcomes (1)
Incidence rates of all adverse events, treatment-emergent adverse events and adverse device events from time of OTL38 administration through participants' first, post-operative appointment with surgeon.
