Inyección de indigotindisulfonato de sodio, USP como ayuda en la determinación de la permeabilidad ureteral

4 de noviembre de 2026 actualizado por: Prove pharm

Un estudio multicéntrico, aleatorizado y abierto para evaluar la seguridad, la eficacia y la satisfacción del médico de dos dosis diferentes de Bludigo ™ (inyección de indigotindisulfonato de sodio, USP) al 0,8% cuando se usa como ayuda en la determinación de la permeabilidad ureteral

This is a randomized, multicenter study to evaluate the efficacy and safety of two dose levels (2.5 mL and 5.0 mL) of Bludigo when used as an aid in the determination of ureteral patency.

Descripción detallada

Subjects scheduled for a surgical procedure in which the patency of the ureter must be assessed by cystoscopy following the procedure, age 18 to 85 years inclusive, will be screened for participation. Screening will occur within 30 days before study drug administration (Day of Surgery). After signing the informed consent, review of inclusion and exclusion criteria will be performed, the collection of concomitant medications, medical history, physical examination, baseline laboratory testing, 12-lead ECG, and vital sign measurements will be completed during the screening visit.

On the day of surgery (Day 1) subjects will be evaluated for eligibility for randomization. Eligible subjects will be stratified by BMI (<30.0 kg/m2or ≥ 30.0 kg/m2) and randomized in a 1:1 ratio to receive a dose of either Bludigo™ high dose (5.0 mL) or Bludigo™ low dose (2.5 mL). Each randomized subject will serve as his/her own control (i.e., intra-patient controlled) by receiving a dose of normal saline prior to receiving the randomized Bludigo™ dose.

All treated subjects will have a follow-up visit 7 to 30 days (± 2 days) after the procedure. A final telephone follow-up call will occur on Day 30 (± 2 days) in subjects who have the follow-up visit before Day 28. Safety assessments will include monitoring of AEs during and post the procedure, clinical laboratory tests, 12-Lead ECG, and vital sign measurements.

¿Qué mide el estudio?

Medidas de resultado primarias

Medida de resultado
Medida Descripción
Periodo de tiempo
Paired sample difference (Bludigo™-Saline) in urine jet conspicuity score .
Periodo de tiempo: 10 minutes post study drug administration

Visualization will be measured by a conspicuity scale designed to provide an objective tool applicable to the visualization of the urinary flow from the ureteral orifices when determining ureter patency. The conspicuity of the urine flow from the ureteral orifices is defined using the 5-point conspicuity score as follows:

  1. = No jet observed
  2. = Weak jet, little color contrast
  3. = Color contrast or significant jet flow
  4. = Strong jet flow with good color contrast
  5. = Strong jet flow with striking contrast in color

Paired sample difference (Bludigo™-Saline) in conspicuity score (PSDCS). PSDCS will be calculated for each ureter (left or right) for each subject from each reviewer.

Responders to Bludigo
Periodo de tiempo: 10 Minutes post study drug administration

Visualization will be measured by a conspicuity scale designed to provide an objective tool applicable to the visualization of the urinary flow from the ureteral orifices when determining ureter patency. The conspicuity of the urine flow from the ureteral orifices is defined using the 5-point conspicuity score as follows:

  1. = No jet observed
  2. = Weak jet, little color contrast
  3. = Color contrast or significant jet flow
  4. = Strong jet flow with good color contrast
  5. = Strong jet flow with striking contrast in color

A subject is considered a responder to Bludigo™ if there is >=1 point improvement in the conspicuity score following the Bludigo™- treatment vs the saline treatment and the conspicuity score for the Bludigo™ treatment must be (3, 4, or 5). The responder criteria will be assessed separately for each ureter (left or right) from each reviewer.

Physician Satisfaction
Periodo de tiempo: 10 Minutes post study drug administration

To determine physicians' overall satisfaction with the Bludigo™ treatment by assessing the proportion of surgeons who agree using the 5-point Physician Satisfaction Agreement Scale (PSAS) with the statement:

"Compared to the saline treatment, my ability to assess ureter patency was improved after the addition of Bludigo™."

  1. = Strongly Agree
  2. = Agree
  3. = Neither Agree nor Disagree
  4. = Disagree
  5. = Strongly Disagree A surgeon's evaluation is considered satisfactory if the rating is either a 1 (strongly agree) or 2 (agree).
