About

This study is designed to describe the metabolism of AT1001 (migalastat HCl) and the contribution of metabolism and urinary excretion to its overall elimination as part of the continuing assessment of the safety and effectiveness of the drug.

This is a Phase 1, single-site, open-label, single dose study of the absorption, metabolism and excretion of radiolabeled AT1001 in healthy male subjects between 30 and 55 years of age, inclusive. Six subjects will be dosed, with the goal of having at least 4 subjects complete the study through follow-up. All subjects will be screened within 28 days before admission to the Clinical Unit. Subjects will be confined to the clinical unit for 10 days after dosing and will return to the clinic for a follow-up visit 28 days after dosing.

Each subject will receive a single oral dose of AT1001 as an aqueous solution containing 150 mg [14C] AT1001 (1 μCi). Blood, duodenal bile, expired air, urine, and feces samples will be collected at specified time points after dosing throughout the period of confinement at the study site. Safety will be assessed throughout the study by monitoring clinical laboratory tests, ECGs, physical examinations, vital signs, and adverse events. The total duration of the study for each subject is approximately 8 weeks.

Exclusion criteria

Any previous or ongoing clinically significant illness, medical condition, medical history, physical findings, ECG finding, or laboratory abnormality that, in the investigator's opinion, could affect the safety of the subject, or alter the absorption, distribution, metabolism, or excretion of the study drug, or could impair the assessment of study results
History or presence of significant ophthalmic, cardiovascular, pulmonary, hepatic, renal, hematologic, gastrointestinal, endocrine, immunologic, dermatologic, neurologic or psychiatric disease
History of a major surgical procedure within 30 days before screening
History of blood or plasma donation or blood loss (>400 mL) within 60 days before screening
History of drug or alcohol abuse or addiction within 2 years before screening
Intake of more than 2 alcoholic drinks per day within the past 7 days or use of alcohol-, grapefruit-, or caffeine-containing foods or beverages within 72 hours prior to Day -1
Self-reported smoker (occasional or frequent) or positive urine cotinine test (measured at screening and baseline) exceeding the local laboratory's lower limit of detection.
Presence or history of severe adverse reaction to any drug; history of hypersensitivity or allergic reaction to AT1001 or related iminosugars
Receipt of any investigational agent or participation in any other interventional clinical trial within the past 30 days
Participation in any clinical study involving administration of [14C] labeled compound(s) within the last 12 months. A subject's previous effective dose will be reviewed by the medical investigator to ensure there is no risk of contamination/carryover into the current study
At Day -1, a drug toxicology screen positive for any illicit substances, or alcohol
Anticipated need for alcohol, tobacco, or any drug during the period of confinement in the clinical unit
