Protection Against Benzene Toxicity
An observational study of Leukemia and Aplastic Anemia, run by National Institute of Environmental Health Sciences (NIEHS) at 1 site in United States.
Trial summary
We are investigating the role of an enzyme (NQO1) in protection against the bone marrow toxicity of the occupational and environmental toxicant benzene. All of the proposed studies involve use of human bone marrow cells in-vitro to define mechanisms of NQO1-mediated protection. Read more about this study

About this study
Official title: NQO1 in Protection Against Benzene Toxicity
We are investigating the role of an enzyme (NQO1) in protection against the bone marrow toxicity of the occupational and environmental toxicant benzene. All of the proposed studies involve use of human bone marrow cells in-vitro to define mechanisms of NQO1-mediated protection. Cells are obtained from healthy volunteers and protocols have undergone IRB review and approval.

Questions about this trial
What is this clinical trial studying?
An observational study of Leukemia and Aplastic Anemia, run by National Institute of Environmental Health Sciences (NIEHS) 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?
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: finished, as of the sponsor's last update on 24 Jun 2005. 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 is completed, but results are not available in the source record. That does not mean the treatment did or did not work.
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.
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 24 Jun 2005.
