Hematotoxic Effects of Particulate Exposure
An observational study of Cancer, run by National Institute of Environmental Health Sciences (NIEHS).
Trial summary
Hematotoxicity is caused by a number of agents such as a benzene by-product called hydroquinone and the antitumor agent doxorubicin. This is a basic research study, conducted using normal human donors, of mechanisms involved in hematotoxicity and of the protective response of human hematopoietic progenitor cells to… Read more about this study

About this study
Official title: Hematotoxic Effects of Benzene and Doxorubicin
Hematotoxicity is caused by a number of agents such as a benzene by-product called hydroquinone and the antitumor agent doxorubicin. This is a basic research study, conducted using normal human donors, of mechanisms involved in hematotoxicity and of the protective response of human hematopoietic progenitor cells to hematotoxic agents. Tumor necrosis factor exposure protects these cells from a subsequent exposure to hematotoxic agents. The alteration of gene expression in these cells caused by tumor necrosis factor is being studied. Additionally, the tumor necrosis factor-induced biochemical pathways involved in protection of human hematopoietic progenitor cells will be studied.

Questions about this trial
What is this clinical trial studying?
An observational study of Cancer, run by National Institute of Environmental Health Sciences (NIEHS).
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 4 Sep 2006. Status can change between updates, so confirm with the study contact before making plans.
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 4 Sep 2006.
