Detailed Description:

Gaucher disease is a lysosomal storage disorder resulting from a deficiency in the key enzyme beta-glucocerebrosidase (GCase). The enzyme deficiency is caused by genetic mutations, which can result in the production of misfolded GCase. AT2101 is designed to act as a pharmacological chaperone by selectively binding to the misfolded GCase and helping it fold correctly, which may restore GCase activity.

This study is being conducted to test the safety of AT2101 in patients with type I Gaucher disease who have not already received enzyme replacement therapy (ERT) or substrate reduction therapy (SRT), or who have not received ERT or SRT in the 12 months before screening. This study will also evaluate the effects of AT2101 on parameters that are commonly abnormal in Gaucher disease. The study will involve 9 visits over 29 weeks.

  Eligibility

Ages Eligible for Study:   18 Years to 74 Years
Genders Eligible for Study:   Both
Accepts Healthy Volunteers:   No
Criteria

Inclusion Criteria:

  • Confirmed diagnosis of type 1 Gaucher disease with a known genotype and a documented missense gene mutation in at least one of the two mutated GBA alleles
  • Clinically stable
  • Treatment naïve to enzyme replacement therapy (ERT) and substrate reduction therapy (SRT) or has not received ERT or SRT in the 12 months before screening
  • Willing not to initiate ERT or SRT treatment during study participation
  • At the screening period visit, subjects must meet at least two of the following criteria:
  • Platelet count of ≤ 150,000 per microliter
  • Hemoglobin ≤ 12 g/dL for females and ≤13 g/dL for males
  • Liver volume ≥ 1.25 multiples of normal
  • Spleen volume ≥ 2 multiples of normal
  • All subjects of reproductive potential are required to practice an acceptable method of contraception
  • Provide written informed consent to participate in the study

Exclusion Criteria:

  • A clinically significant disease, severe complications from Gaucher disease, or serious illness that may preclude participation in the study in the opinion of the Investigator
  • During the screening period, any clinically significant findings, as deemed by the Investigator
  • Partial or total splenectomy
  • Documentation of moderate or severe pulmonary hypertension, defined as pulmonary arterial pressure (PAP) > 35 mmHg or significant Gaucher related lung disease
  • History of allergy or sensitivity to the study drug or any excipients, including any prior serious adverse reaction to iminosugars
  • Pacemaker or other contraindication for MRI scanning
  • Pregnant or breast-feeding
  • Current/recent drug or alcohol abuse
  • Treatment with any investigational product in the last 90 days before study entry
  • Treatment in the previous 90 days with any drug known to have a well defined potential for toxicity to a major organ
  • Presence of symptoms of gastrointestinal, liver or kidney disease, or other conditions known to interfere with the absorption, distribution, metabolism, or excretion of drugs
