Is this trial a fit for you?

Likely a good fit

Ideal candidates are adults aged 16–75 undergoing robotic-assisted colectomy with no significant liver disease, kidney impairment, or prior investigational drug or device exposure within 6 months.

Probably not a fit

Patients with severe liver or kidney dysfunction, active non-colorectal cancer, pregnancy, or hypersensitivity to indocyanine green may not experience benefit or could be excluded for safety reasons.

What this trial studies

This Phase 3 interventional study tests whether IV IS-001 improves intraoperative visualization of the ureters when using the da Vinci Surgical System with Firefly imaging during robotic-assisted colectomy. Participants are adults aged 16 to 75 undergoing robotic-assisted colectomy and have specific safety criteria to minimize risk. The trial assesses safety and efficacy of IS-001 in enhancing ureter delineation to reduce intraoperative injury. Sites include Hoag Memorial Hospital Presbyterian, Yale New Haven Hospital, and Orlando Health, with Intuitive Surgical as lead sponsor. Enrollment and eligibility focus on patients without significant hepatic impairment, kidney function within safe limits, and no conflicting conditions.

Why it matters

Potential benefit: If successful, IS-001 could help surgeons prevent ureter injuries by improving real-time ureter visualization during surgery.

How similar studies have gone: Previous imaging agents with fluorescence-guided techniques have shown promise in improving intraoperative visualization in other procedures; this study tests a similar approach for ureter delineation.
