Official title: A Phase I, Randomized, Single-Blind, Four-Period Cross-Over, Placebo-Controlled, Dose-Escalation Study to Evaluate the Safety and Pharmacokinetics of Single Oral Doses of GR181413A/AT1001 in Healthy Japanese Subjects
Trial description: GR181413A/AT1001 (migalastat hydrochloride) is a low molecular weight iminosugar, an analog of the terminal galactose group that is cleaved from the substrate GL-3. This compound was researched and developed as a drug for treatment of Fabry disease. This study, MGM115806, will be the first administration of GR181413A/AT1001 to Japanese subjects to investigate the safety, tolerability and pharmacokinetics of single oral doses in healthy Japanese adult subjects. Approximately 12 subjects will receive three treatments of 50, 150 and 450 mg GR181413A/AT1001 under fasted conditions plus placebo in a dose ascending crossover design. Serial pharmacokinetic samples will be collected and safety assessments will be performed following each dose. The pharmacokinetics and dose proportionality of GR181413A/AT1001 after single oral doses of GR181413A/AT1001 at the dose levels of 50, 150 and 450 mg under fasted conditions will be assessed.

    Female & Male
    Age
    20 - 55 Years
    Accepts healthy volunteers
    yes
    • 1.Healthy as determined by a responsible and experienced physician, based on a medical evaluation including medical history, physical examination, laboratory tests and cardiac monitoring. A subject with a clinical abnormality or laboratory parameters outside the reference range for the population being studied may be included only if the Investigator and the GSK Medical Monitor agree that the finding is unlikely to introduce additional risk factors and will not interfere with the study procedures.
    • 2. Male or female between 20 and 55 years of age inclusive, at the time of signing the informed consent.
    • 1. A positive pre-study Hepatitis B surface antigen or positive Hepatitis C antibody result within 3 months of screening.
    • 2. A positive pre-study drug/alcohol screen.
