Randomized, Double-Blind, Controlled Study to Evaluate Safety and Pharmacokinetics of Single Ascending Doses of ASP5354, an Investigational Imaging Product, in Healthy Adult Volunteers.

ABSTRACT: Intraoperative ureter identification helps reduce the risk of ureteral injury. Currently, no suitable agents for real-time ureter visualization are approved. ASP5354 (TK-1) is a novel indocyanine green derivative. In this first-in-human phase 1, double-blind, sequential ascending-dose study, urethral catheters were placed in 6 healthy volunteers who were randomized to single-dose, intravenous ASP5354 0.1 mg (n = 4) or placebo (n = 2). Sequential dose escalations to 0.5-, 2-, 8-, and 24-mg ASP5354 in new cohorts were contingent upon Dose-Escalation Committee approval after review of pharmacokinetic (PK) and safety data. Blood and urine samples were collected over 24 hours following dose administration. Objectives were to assess the safety/tolerability and PK of ASP5354. Treatment-emergent a
