What the study statuses mean

This study's is highlighted.

Recruitment status, easiest to join first

Recruiting now This study
This trial is taking on new participants right now.
Not yet recruiting
Registered, but not yet taking participants.
By invitation only
Not open to general applications. Only people the study team invites can take part.
Paused
Paused for now. It may or may not start again.
Ongoing
Running, but no longer taking on new participants.
Completed
The trial has finished. Results may not be published yet.
Stopped early

Cancelled
Cancelled before anyone took part.

Expanded access (not trials)

Expanded access
Not a trial. This treatment can be requested outside a study, case by case, for people who qualify.
Expanded access (paused)
Not a trial. The treatment can normally be requested outside a study, but is unavailable right now.
Expanded access (ended)
Not a trial. The treatment could once be requested outside a study, but no longer can.

Summary

This study tests an injection called IS-001 that makes ureters glow under special imaging during robotic colorectal surgery. The goal is to help surgeons see the ureters more clearly and avoid accidentally injuring them. About 146 adults having robotic-assisted colorectal surgery will take part. The dye is given through a vein and its effects are measured up to 30 minutes after injection.

Inclusion Criteria: 1. Male and female participants between the ages of 16 and 75, inclusive 2. Participant is scheduled to undergo robotic-assisted colectomy using the da Vinci X/Xi Surgical System with SFF Fluorescence Imaging Exclusion Criteria 1\. Participant is pregnant or nursing 2. Participant has known current acute or chronic hepatitis B virus (HBV) or hepatitis C virus (HCV) infection 3. Participant has any of the following screening laboratory values: eGFR \< 30 mL/min/1.73 m2 1. Aspartate aminotransferase (AST) ≥ 2.5 × ULN 2. Alanine aminotransferase (ALT) ≥ 2.5 × ULN 3. Total Bilirubin \> 2mg/dL 4. Participant has any concomitant non-colorectal cancer 5. Participant has any circumstances that, in the judgment of the Investigator, might make them not a suitable candidate for the study 6. Participants have already been enrolled in another investigational drug or device study within the past 6 months 7. Participants with known or suspected hypersensitivity to indocyanine green (ICG) or any components of the formulation used 8. Participant is expected to receive or has received other methods for ureter identification during the surgery (e.g., ureteral stent placement, illuminated catheters, retrograde ICG injections) before the administration of IS-001 9. The duration of the surgery is expected to be less than 90 minutes as determined during preoperative planning.
