ArmTypeDescription
EfficacyOTHERSingle intravenous injection of IS-001 and ureter visualization and delineation will be compared in white light standard of care and near-infrared (NIR) imaging mode.
Single ArmEXPERIMENTALSingle Arm Safety and Feasibility Study of IS-001 with 20 mg in Multiple Injections
Dose-escalationEXPERIMENTALDose-cohort escalation of single intravenous injection of IS-001 starting with 20 mg (n=8), escalating in 20 mg increments until optimal dose is determined.
Optimal dose-characterizationEXPERIMENTALSingle intravenous injection of IS-001 at the optimal dose will be administered to subjects assigned to the treatment group. Safety control subjects will not receive any study drug but will undergo robotic surgery and all associated safety assessment clinical trial procedures.
