Detailed Description:
ASM deficiency (ASMD), also known as Niemann-Pick A and B disease, is a rare genetic disorder in which reduced activity of the lysosomal enzyme, ASM, leads to the accumulation of sphingomyelin primarily in macrophages throughout the body. This deficiency results in characteristic features such as hepatosplenomegaly, thrombocytopenia, interstitial lung disease, growth retardation, coronary artery disease, fatigue, and in severe cases, neurodegeneration with death in early childhood. There is no specific treatment for this disease. This Phase 1 safety study will seek to enroll a minimum of 12 and a maximum of 30 eligible adults patients with ASMD with each patient participating for approximately 7 weeks.
Eligibility| Ages Eligible for Study: | 18 Years to 65 Years |
| Genders Eligible for Study: | Both |
| Accepts Healthy Volunteers: | No |
Inclusion Criteria:
- Signed, informed consent by the patient or legal guardian prior to performing any study-related procedures;
- Have ≤ 0.2 nmol/hr/mg protein ASM activity in peripheral leukocytes, as measured by the reference laboratory;
- Have a diffusing capacity (DLco) > 30% of the predicted normal value;
- Have a spleen volume ≥ 2x normal
- Female patients of childbearing potential must have a serum pregnancy test negative for β-hCG and agree to use a reliable birth control method for the duration of the study.
Exclusion Criteria:
- Is pregnant or lactating;
- Has received an investigational drug within 30 days prior to study enrollment;
- Has a medical condition, including serious intercurrent illness, active hepatitis B or C or human immunodeficiency virus (HIV) infection, cirrhosis, > stage 3 liver fibrosis, INR >1.5, platelet count < 60.0x10^3/µL, significant cardiac disease (e.g. pulmonary artery pressure > 40 mm Hg, moderate or severe valvular dysfunction, or < 40% left ventricular ejection fraction by echocardiography (ECHO)), or any other extenuating circumstances that may significantly interfere with study compliance including all prescribed evaluations and follow-up activities;
