A Study to Assess the Absorption, Metabolism and Excretion of Migalastat Hydrochloride (AT1001-014)
A Phase 1 Study to Investigate the Absorption, Metabolism and Excretion of [14C] AT1001 (Migalastat Hydrochloride) Following a Single Oral Administration in Healthy Volunteers (AT1001-014)
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.

Arms and Interventions
Participant Group / Arm |
Intervention / Treatment |
---|---|
Experimental: [14C] AT1001 Arm
Each subject will receive a single oral dose of 150 mg of [14C] AT1001 as an aqueous solution containing 1 μCi AT1001 on Study Day 1.
|
150 mg of [14C] labelled AT1001 will be administered as a solution (prepared by weighing 150 mg of AT1001 powder and dissolving in 100 mL of water).
The entire solution will be swallowed orally.
After ingestion of study medication, the dosing bottle will be rinsed with 50 mL of water and this will be ingested by the subject.
This rinse procedure should be performed twice.
Following the second rinse ingestion, the subjects should be instructed to drink additional water to bring the total volume ingested to 240 mL.

Primary Outcome Measures
Outcome Measure |
Measure Description |
Time Frame |
---|---|---|
Recovery of total radioactivity in urine
Time Frame: Days 1 to 11
|
Urine will be collected: pre-dose (-12-0 hours), 0-12 and 12-24 hours on Day 1, 24-hourly on Days 2-10; the last sample will be collected on Day 11.
Total radioactivity excreted in urine will be calculated for the entire collection period.
The excretion rate will be calculated from total radioactivity collected in urine, divided by the duration of collection.
The percentage of dose excreted in urine will be calculated from the total amount excreted in urine divided by the dose administered, multiplied by 100.
|
Days 1 to 11
|
Recovery of total radioactivity in feces
Time Frame: Days 1 to 11
|
Feces will be collected: predose (-24 to 0 hours); all bowel movements post-dose will be collected on Days 1 to 10; the last sample will be collected on Day 11.
Total radioactivity excreted in feces will be calculated for the entire collection period.
The excretion rate will be calculated from total radioactivity collected in feces, divided by the duration of collection.
The percentage of dose excreted in feces will be calculated from the total amount excreted in feces divided by the dose administered, multiplied by 100.
