The goal of this clinical trial is to determine if the drug Nizaracianine Triflutate can help surgeons see and avoid the ureters during abdominopelvic surgery. The ureters are thin-wall, collapsible tubes that connect the kidneys to the bladder. They are difficult to see during surgery and are sometimes damaged accidentally. The main questions to answer are: 1) is this drug safe for use in patients undergoing abdominopelvic surgery and 2) can the drug see the ureters while simultaneously providing information about how well they are working. The clinical trial has 3 parts. Surgery patients enrolled in the first part (Phase 2) will receive drug at different doses to determine the best dose. Patients enrolled in the second part (Phase 3A) will be randomly assigned to drug or placebo (sugar), at the best dose from Phase 2, so the two can be compared directly. Patients enrolled in the final part (Phase 3B) will all receive drug at the best dose from Phase 2.
Human surgery often suffers from poor visual contrast among anatomical landmarks within the surgical field and distinguishing one anatomical structure from another becomes nearly impossible if covered by connective tissue, blood, and/or bodily fluids. A major unsolved problem in surgical imaging is anatomical enhancement of the ureters. Damage to the ureters is a serious unintended complication of abdominopelvic and retroperitoneal surgery, with rates as high as 30% in certain gynecological procedures. Ureter damage also leads to extraordinarily high patient morbidity and cost. Currently, to…
Inclusion Criteria: * Age ≥ 18 years old * Scheduled to undergo a medically necessary abdominopelvic surgical procedure expected to last ≥ 2 hours (Phase 2) or any duration (Phase 3), during which one or more ureters should be visualized during the procedure. All abdominopelvic surgical procedures are eligible unless specifically excluded in the Exclusion Criteria. * For Phase 2, the procedure must require identification of one or both ureters using dissection, mobilization, or other surgical means. * The planned surgical procedure is open or minimally invasive surgery (MIS), including roboti…
Participants will receive up to 3 intravenous bolus injections with a minimal interval between doses of 60 minutes (surgeon discretion). Dose will be 1.0 or 2.5 mg depending on trial phase.
In Phase 3A only, \~50 subjects will be randomly allocated to receive sugar placebo
