Using Indigotindisulfonate Sodium to Check Ureter Function in Patients with Kidney Issues
An Open-Label, Randomized, Parallel Group Study to Investigate the Influence of Renal Impairment on the Efficacy and Safety of Two Doses of Bludigo™ When Used as an Aid in the Determination of Ureteral Patency
This study is testing if a new dye can help doctors check how well the ureters are working in people with kidney problems.

What this trial studies
This open-label, randomized, multicenter study evaluates the efficacy and safety of two doses of Indigotindisulfonate Sodium Injection, USP 0.8% in determining ureteral patency in patients with varying degrees of renal impairment. Participants will be stratified into four cohorts based on their estimated glomerular filtration rate (eGFR) and will undergo a surgical procedure requiring cystoscopy to assess ureter function. The study will enroll approximately 48 subjects across multiple centers in the United States, with a comprehensive screening and evaluation process prior to treatment.
Who should consider this trial
Good fit: Ideal candidates are adults aged 18 to 85 with varying degrees of renal impairment scheduled for a surgical procedure requiring ureter assessment.
Not a fit: Patients with normal renal function who do not require ureteral assessment may not benefit from this study.
Why it matters
Potential benefit: If successful, this study could improve the assessment of ureteral function in patients with renal impairment, leading to better surgical outcomes.
How similar studies have performed: While this approach is novel in its specific application, similar studies have shown promise in evaluating renal function and ureteral patency.
Eligibility criteria
Show full inclusion / exclusion criteria
Inclusion Criteria: * Subjects between ≥ 18 and ≤ 85 years old * Subjects who signed a written IRB approved, informed consent form * Subjects scheduled for a surgical procedure in which the patency of the ureter must be assessed by cystoscopy following the procedure. * An estimated glomerular filtration rate (eGFR) at baseline will be determined using the Modification of Diet in Renal Disease formula (MDRD) and standardized by using individual's body surface area. Subject's renal function will be defined based on the following criteria: * Normal subjects: eGFR of ≥90 mL/min * Mild renal impairment: eGFR 60 to 89 mL/min * Moderate renal impairment: eGFR 30 to 59 mL/min * Severe renal impairment: eGFR 15 to 29 mL/min Subjects with normal renal function that are judged to be in good health based on medical history, physical examination, vital signs, and laboratory safety tests performed at the Screening Visit and/or prior to administration of study drug. Patients with renal impairment (mild, moderate, or severe) who have a diagnosis of chronic (\>6 months), stable (no acute episodes of illness within the previous 2 months due to deterioration in renal function) renal insufficiency meeting criteria at the Screening Visit Exclusion Criteria: * Subjects with eGFR \<15 mL/min or expected need for dialysis in the near future, or having only 1 kidney * Subjects with known severe hypersensitivity reactions to Bludigo™ or other dyes, including contrast dyes * Known history of drug or alcohol abuse within 6 months prior to the time of screening visit * Subjects, as assessed by the Investigator, with conditions/concomitant diseases precluding their safe participation in this study (e.g., major systemic diseases) * Unable to meet specific protocol requirements (e.g., scheduled visits) or subject is uncooperative or has a condition that could lead to non-compliance with the study procedures * Subject is the Investigator or any Sub-Investigator, research assistant, pharmacist, study coordinator, other staff or relative thereof directly involved in the conduct of the protocol * Subjects with life expectancy \< 6 months * Requirement for concomitant treatment that could bias primary evaluation. * Subjects who are pregnant or breast-feeding
