An Open-Label Study to Evaluate the Absolute Bioavailability of Genz-112638 and the Absorption, Metabolism, and Excretion of [14C]-Genz-112638 in Male Subjects
An Open-Label Study to Evaluate the Absolute Bioavailability of Genz-112638 and the Absorption, Metabolism, and Excretion of [14C]-Genz-112638 in Male Subjects
Objectives:
To determine pharmacokinetic (PK) variables, including absolute bioavailability (F), of Genz-99067, the free base of the L-tartaric acid salt of Genz-112638 as it exists in plasma, after a single intravenous (IV) dose and after a single oral dose of Genz-112638 (unlabeled).
To determine the PK, total recovery, routes and rates of excretion, and the metabolic profile of Genz-99067 after 5 days of BID oral dosing with unlabeled Genz-112638 followed by a single dose of [14C]-Genz-112638.
The maximum study duration for an individual subject was approximately 65 days from the beginning of Screening through the Safety Follow-up visit.
Inclusion Criteria: Having given written informed consent prior to undertaking any study-related procedure The subject has a body weight of 50 to 100 kg [110 to 220 pounds (lb)] with a body mass index (BMI) less than 30 kilograms per square meter (kg/m2) at Screening.
The subject's physical examination results, vital signs, laboratory assessments, and cardiac assessments are within normal limits or, if abnormal, are not clinically significant at Screening and Day -1. Exclusion Criteria: Participants are excluded from the study if any of the following criteria apply:
Prolonged QTc interval (eg, repeated demonstration of a QTc interval ≥450 msec), family history of long QT or Brugada Syndrome, and/or history of sudden death in a first-degree relative.
The subject receives an immunization within 30 days of providing informed consent.
The subject has a history of drug allergies (eg, significant rash, hives, etc in response to antibiotics).
The above information is not intended to contain all considerations relevant to the potential participation in a clinical trial.
