Safety and Effectiveness of Azidothymidine (AZT) in HIV-Positive Patients With Hemophilia
A Phase 1 study testing Zidovudine in people with HIV Infections and Hemophilia A, run by National Institute of Allergy and Infectious Diseases (NIAID) at 2 sites in United States.
Trial summary
The purpose of this study is to see if giving azidothymidine (AZT) to HIV-positive patients with hemophilia is safe and if it is effective in lowering HIV levels and boosting the immune system. HIV infects and inactivates certain blood cells that are part of the body's immune system. Read more about this study

About this study
Official title: A Phase I Trial to Evaluate Azidothymidine (AZT) in the Treatment of HIV Infections in Patients With Hemophilia
The purpose of this study is to see if giving azidothymidine (AZT) to HIV-positive patients with hemophilia is safe and if it is effective in lowering HIV levels and boosting the immune system.
HIV infects and inactivates certain blood cells that are part of the body's immune system. The damage to the body's immune system can result in unusual infections and/or unusual forms of cancer. A large percentage of hemophiliacs are HIV-positive and there is a clear risk for the development of AIDS in these patients. AZT may be effective in lowering HIV levels and boosting the immune system but its side effects are not understood in these patients.
Read the detailed description
There is a clear risk for development of AIDS in hemophilic patients. AZT administration has been shown to inhibit HIV replication in vitro. Patients taking AZT have experienced fewer opportunistic infections and improvements in measures of immunity. The most common laboratory abnormalities observed with AZT are hematologic. However, the clinical and laboratory toxicity of AZT remains poorly understood in hemophiliacs. Hepatitis and liver dysfunction are more common in this population compared to other groups at risk for HIV infection. Because AZT is largely metabolized in the liver, drug pharmacokinetics needs to be evaluated in this patient population.
Both hemophiliacs and non-hemophiliacs take AZT for a period of 12 weeks. The first dose is administered intravenously. AZT is then given orally every 4 hours while awake (5 doses per day). Patients are evaluated by physical examinations and laboratory assessments. These include HIV culture of blood and leukocyte counts, lymphocyte counts, and lymphocyte subsets measured at study entry and every 4 weeks thereafter. Patients are hospitalized for pharmacokinetic studies at study entry and at Weeks 6 and 12. Each of these studies involves both intravenous and oral administration within 48 hours of one another. Blood is sampled at 0, 0.5, 1, 2, 3, 4, 6, 8, 10, and 12 hours after each administration and urine is collected every 2 hours for 12 hours.

The record says: finished, as of the sponsor's last update on 29 Oct 2021. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 2 sites 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 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?
On the ClinicalTrials.gov record for NCT00000705, which also lists 4 linked publications.
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 29 Oct 2021.
