About this study

Metabolomics is the study of metabolic pathways and the unique biochemical molecules which result from the regulatory response to physiological stressors, disease processes, or drug therapy. By measuring changes in metabolite concentrations, the range of biochemical effects and therapeutic intervention can be determined.

Aspirin exacerbated respiratory disease (AERD) is a chronic inflammatory disease characterized by chronic rhinosinusitis, nasal polyposis, asthma, and airway reactivity to aspirin and/or other nonsteroidal anti-inflammatory drugs (NSAIDs). This reaction to aspirin during challenge/desensitization is equivalent to an allergic drug reaction however we are able to evaluate these specific reactions in a controlled, clinical environment. This population of patients undergoing aspirin desensitization is ideal for studying metabolomics as serial blood sampling can be performed in patients before, during a reaction, and after aspirin desensitization, thereby allowing each patient to serve as his or her own biological control. The investigator hopes that this study of metabolomics will allow for better methods of identifying anaphylaxis in the future.

Study groupRoleWhat they receive
Aspirin desensitizationThis group of patients has AERD (aspirin exacerbated respiratory disease) and is undergoing aspirin desensitization.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Change in metabolic profile of blood serum metabolites from Baseline to 1 week post-desensitization

    Metabolic profiling will be done on specific blood serum metabolites including lipid mediators, amino acids, and leukotrienes.

    Measured: before start of aspirin desensitization, 2 hours into desensitization, at time of reaction(s) - an expected average of 6 hours into desensitization, 1 week post-desensitization

Questions about this trial

What is this clinical trial studying?

An observational study of Patients With AERD Undergoing Aspirin Desensitization, run by Massachusetts General Hospital 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 1 inclusion and 1 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The record says: withdrawn, as of the sponsor's last update on 7 Mar 2019. 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.

Are results available for this study?

The study was withdrawn before enrolling participants, so there are no results.

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?

Change in metabolic profile of blood serum metabolites from Baseline to 1 week post-desensitization (time frame: before start of aspirin desensitization, 2 hours into desensitization, at time of reaction(s) - an expected average of 6 hours into desensitization, 1 week post-desensitization). 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 7 Mar 2019.
