Conditions

Ureter Injury

Brief summary

This study evaluates the safety and feasibility of intravenous injection of IS-001 to aid in intraoperative ureter structure delineation

Detailed description

Injury to the ureter, the duct by which urine passes from the kidney into the bladder, is a well-known and serious complication of pelvic and abdominal surgery that frequently goes unrecognized intraoperatively. This study seeks to evaluate the safety and feasibility of intravenous IS-001 injection to improve surgeon ureter visualization during robotic-assisted surgery with the da Vinci® Surgical System and Firefly® imaging.

Inclusion criteria

1. Male and female subjects between the ages of 18 and 75, inclusive 2. Subject is scheduled to undergo robotic-assisted rectal, sigmoid, or left colon resection surgery using the da Vinci® X/Xi Surgical System with Firefly® Fluorescent Imaging

Exclusion criteria

1. Subject is pregnant or nursing 2. Subject has known hepatitis B virus (HBV) or hepatitis C virus (HCV) infection 3. Subject has any of the following screening laboratory values: 1. eGFR \< 60 mL/min/1.73 m\^2 2. Aspartate aminotransferase (AST) or serum glutamic oxaloacetic transaminase ≥ 2.5 × ULN 3. Alanine aminotransferase (ALT) or serum glutamic pyruvic transaminase ≥ 2.5 × ULN 4. Subject is already enrolled in another investigational drug or device study receiving therapeutic agents within the past 6 months 5. Subject has any other condition or personal circumstance that, in the judgment of the Investigator, might interfere with the collection of complete quality data or represents an unacceptable safety profile 6. Subjects with known or suspected hypersensitivity to indocyanine green (ICG) or any components of the formulation used.

Design outcomes

Primary

MeasureTime frameDescription
Evaluate ureter visualization by Independent Reader10 minutes after first IS-001 injection during surgeryIndependent reader assessment of ureter visibility of a 5 second video segment of the surgical field in both Firefly® and standard white light comparator mode on a Five-point rating scale where 1 = Not Visible, 1 = Questionably Visible, 3 = Low Visibility, 4 = Visible, 5 = Clearly Visible

Secondary

MeasureTime frameDescription
Evaluate ureter visualization by Intra-operative surgeon10 minutes after first IS-001 injection during surgeryIntra-operative surgeon assessment of ureter visibility in both Firefly® and standard white light comparator mode on a Five-point rating scale where 1 = Not Visible, 1 = Questionably Visible, 3 = Low Visibility, 4 = Visible, 5 = Clearly Visible
Ureter Delineation Efficacy as Length of Line Drawn10 minutes after first IS-001 injection during surgeryIndependent reader assessment of ureter delineation on a still frame of the surgical field in both Firefly® and standard white light comparator mode. Length of line drawn on still frame where ureter is visible to independent reader is compared between imaging conditions.
Evaluate fluorescent intensity of ureter by signal to background analysis10 minutes after first IS-001 injection during surgeryFluorescent intensity of ureter evaluated as signal to background
