A Study for Ureter Visualization, Using ASP5354 in Subjects Undergoing Laparoscopic/Minimally Invasive Colorectal Surgery
A Phase 2 Randomized Open-label, Dose-ranging Study for Ureter Visualization Using ASP5354 in Subjects Undergoing Laparoscopic/Minimally Invasive Colorectal Surgery
Study Overview
Status
Intervention / Treatment
Detailed Description
Participants were randomly assigned at each dose level (dose A, B, C). During a standard minimally invasive surgery, visualization of the surgical field was assessed following the placement of the near infrared fluorescence (NIR F) imaging system proximal to the ureter of interest and then ASP5354 was administered.
Based on Visualization Review Committee (VRC) review of the initial 3 dose levels, if none of the doses selected had visualization, then additional two dose levels (dose D and E) was planned to be added; if 1 dose selected has visualization, then the dose level D was planned to be added. The dose level F was planned to be added if only the dose E level has visualization.

- Subject has a mean resting heart rate ≤ 45 bpm or ≥ 115 bpm, mean systolic blood pressure (SBP) ≥ 160 mmHg or mean diastolic blood pressure (DBP) ≥ 100 mmHg on day -1. If the mean blood pressure exceeds the limits above, repeat readings can be taken. Subject who has adequately controlled blood pressure is eligible.
- Subject has a mean corrected QT interval (Triplicate electrocardiogram [ECG]) using Fridericia's formula (QTcF) > 430 msec (for male subjects) and > 450 msec (for female subjects) on day -1. If the mean QTcF exceeds the limits above, the mean of 1 additional triplicate ECG may be taken.
Subject has any of the following screening laboratory values:
- Hemoglobin ≤ 9 g/dL
- Absolute neutrophil count ≤ 1500/µL
- Platelet count ≤ 100000/µL
- eGFR < 60 mL/min/1.73 m^2 (Not applicable to subjects enrolled after optimal dose determination.)
- Serum bilirubin ≥ 2 × upper limit of normal (ULN)
- Aspartate aminotransferase (AST) or serum glutamic oxaloacetic transaminase ≥ 2.5 × ULN
- Alanine aminotransferase (ALT) or serum glutamic pyruvic transaminase ≥ 2.5 × ULN
- Subject has taken ICG or other near-infrared fluorescence (NIR)-F imaging agents within 48 hours prior to study treatment administration.
- Subject has taken diuretics or inhibitors of renal transporters defined by Food and Drug Administration (FDA) within 48 hours prior to study treatment administration.
- Subject has used any illicit drugs, unless legally prescribed and is not being abused (amphetamines, barbiturates, benzodiazepines, cannabinoids, cocaine and opiates) within 1 month prior to day -1.
- Subject has a history of alcohol abuse. Subject should not have consumed any alcohol within 48 hours of surgery.

Primary Outcome Measures
Outcome Measure |
Measure Description |
Time Frame |
---|---|---|
Percentage of Participants With Successful Anatomical Visualization of the Index Ureter(s)
Time Frame: 30 minutes postdose through end of surgery (on day 1)
|
The anatomical visualization of the index ureter(s) was assessed by the investigator intraoperatively using a binary "Yes or No" question on the ability to visualize the ureter and was assessed as successful, if both 30 minutes after pudexacianinium chloride dosing and at end of surgery the visualization was assessed as positive (Yes)/successful.
For imputation of missing values at 30 minutes after pudexacianinium chloride administration, the nearest time points before and after the 30 minutes was considered.
If both time points (before and after 30 minutes) were successful, 30 minutes anatomical visualization was imputed as successful.
If both time points were not successful, then 30 minutes anatomical visualization was imputed as not successful, and all other cases were not imputed.

Measure Description |
Time Frame |
---|---|---|
Number of Participants With Treatment Emergent Adverse Events
Time Frame: From first dose of study drug until follow-up period (day 10)
|
An adverse event (AE) was any untoward medical occurrence in a participant administered an investigational product (IP), and which did not necessarily have a causal relationship with the treatment.
An AE could therefore be any unfavorable and unintended sign (including an abnormal laboratory finding), symptom, or disease (new or exacerbated) temporally associated with the use of IP whether or not considered related to the IP.
A TEAE was defined as an AE observed after administration of the IP and up to the follow-up period.
An AE was considered "serious" if the event: results in death;is life-threatening; results in persistent or significant disability/incapacity or substantial disruption of the ability to conduct normal life functions;results in congenital anomaly, or birth defect;requires inpatient hospitalization (except for planned procedures as allowed per study) or leads to prolongation of hospitalization; Other medically important events.
