About this study

Official title: A Phase I, Single-Center, Single Dose, Dose Escalation Study of Recombinant Human Acid Sphingomyelinase (rhASM) in Adults With Acid Sphingomyelinase Deficiency (ASMD)

The purpose of this study is to determine the safe range of single doses of rhASM administered to adults with ASM deficiency.

Read the 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.

Questions about this trial

What is this clinical trial studying?

A Phase 1 study testing rhASM in people with Acid Sphingomyelinase Deficiency and Niemann-Pick Disease, run by Genzyme, a Sanofi Company at 1 site in United States.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 5 inclusion and 7 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: stopped early, as of the sponsor's last update on 19 Mar 2015. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in United States. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

What does this phase mean?

Phase 1 studies test a treatment in a small group of people for the first time or in a new way, mainly to check safety and find the right dose.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

Are results available for this study?

The study was stopped early (reason given: Terminated by sponsor - Single dose safety objective achieved.). Results are not available in the source record.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Safety assessments via physical exam,AE reporting,telemetry heartrate monitoring,ECG,ECHO,clinical lab evaluations,liver and adrenal function tests,cytokine testing,adrenal hormone levels,lipid profile,chest Xrays,liver biopsies,MRI of internal (time frame: Pre-, During-, and Post-infusion (up to 72 hrs); 14 day and 28 day follow-up visit). The study lists 2 primary outcomes in all. It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 19 Mar 2015.
