IS-001 Injection in Patients Undergoing Robotic-Assisted Gynecological Surgery

Phase 3
Recruiting
Conditions
Ureter Injury
Interventions
Drug: IS-001
Registration Number
NCT05954767
Lead Sponsor
Intuitive Surgical
Brief Summary

This study evaluates the safety and efficacy 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 efficacy of intravenous IS-001 injection to improve surgeon ureter visualization during robotic-assisted surgery with the da Vinci® Surgical System and Firefly® imaging.

Exclusion Criteria
  1. Subject is pregnant or nursing.

  2. Subject has known active hepatitis B virus (HBV) or hepatitis C virus (HCV) infection.

  3. Subject is already enrolled in another investigational drug or device study receiving therapeutic agents within the past 6 months
