詳細な説明
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.

説明
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
Exclusion Criteria:
- Subjects with stage 4 or 5 Chronic Kidney Failure as evidenced by a GFR <30 mL/min (calculated using the MDRD formula and standardized by using individual's body surface area) or 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

Paired sample difference (Bludigo™-Saline) in urine jet conspicuity score .
時間枠: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:
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
時間枠: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:
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. |
