Pharmacokinetics and Safety of Gadopiclenol in Japanese Healthy Volunteers

Guerbet27 enrolled

Overview

This single center, single ascending dose, double blind, randomized, placebo-controlled phase I trial will include male and female Japanese healthy volunteers. Within a 4-week run-in period before inclusion in the trial, healthy volunteers will be checked for inclusion/non-inclusion criteria and will then be randomized and administered with gadopiclenol or placebo. For each healthy volunteer, there will be a confinement period of one night before the inclusion visit and 2 days post administration at the clinical unit. The healthy volunteers will return to the clinical unit for safety visit 7 days after study product administration. In each dose group, 6 healthy volunteers (3 male and 3 female) will receive gadopiclenol and 3 healthy volunteers (2M/1F or 1M/2F) will receive placebo (physiological saline solution, 0.9% sodium chloride) in one single intravenous administration. Dose escalation from one group to the next group will be sequential and will be allowed only if the clinical and biological safety of all healthy volunteers from the previous tested dose is acceptable. The decision will be made by a Trial Safety Review Board (TSRB), consisting in members of Guerbet team and the principal investigator.
