Impact of Menstrual Cycle on Antiretroviral Pharmacokinetics in Healthy Women
A Phase 4 study testing tenofovir, emtricitabine and atazanavir in people with Healthy, run by University of Alabama at Birmingham at 1 site in United States.
Trial summary
Data suggest that women taking drugs to treat human immunodeficiency virus (HIV) have higher amounts of drugs in their body compared with men taking the same dose of anti-HIV drugs. The reason for this higher drug exposure has not been determined. Read more about this study

About this study
Data suggest that women taking drugs to treat human immunodeficiency virus (HIV) have higher amounts of drugs in their body compared with men taking the same dose of anti-HIV drugs. The reason for this higher drug exposure has not been determined. The primary purpose of this study is to examine whether the pharmacokinetics (factors that determine the amount of drug in the body) of anti-HIV drugs change during different phases of the menstrual cycle in women and ultimately result in higher amounts of drug in the body compared with men. In other words, we plan to examine whether changes in sex hormones throughout the menstrual cycle affect the amount of anti-HIV drugs in women. The antiretroviral drugs atazanavir, ritonavir, tenofovir and emtricitabine will be studied. This study will be conducted in healthy women since HIV may change the pharmacokinetics of anti-HIV drugs.

What is being measured
The primary outcome is the main question the study is designed to answer.
Tenofovir Systemic Exposure During the Follicular Phase (Days 6-10 After Menses)
Systemic exposure determined by area under the concentration time curve was measured by blood drawn for PK assessment at the following times: 0 (time of dose), 0.5, 1, 2, 4,6, 8, 12 and 24 hours. The Follicular phase starts on day 1 of the menstrual cycle when estrogen and progesterone levels are lowest. this lasts 14 days. Dose administration and PK would have been drawn on day 6, 7, 8, 9, or 10 after Day 1 (start of Follicular phase).

Clinical summary
The research question as the sponsor registered it. This describes what the study plans to test, not what it found.
Data suggest that women taking drugs to treat human immunodeficiency virus (HIV) have higher amounts of drugs in their body compared with men taking the same dose of anti-HIV drugs. The reason for this higher drug exposure has not been determined. The primary purpose of this study is to examine whether the pharmacokinetics (factors that determine the amount of drug in the body) of anti-HIV drugs change during different phases of the menstrual cycle in women and ultimately result in higher amounts of drug in the body compared with men. In other words, we plan to examine whether changes in sex hormones throughout the menstrual cycle affect the amount of anti-HIV drugs in women. The antiretroviral drugs atazanavir, ritonavir, tenofovir and emtricitabine will be studied. This study will be conducted in healthy women since HIV may change the pharmacokinetics of anti-HIV drugs.

Questions about this trial
What is this clinical trial studying?
A Phase 4 study testing tenofovir, emtricitabine and atazanavir in people with Healthy, run by University of Alabama at Birmingham 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 4 inclusion and 2 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: finished, as of the sponsor's last update on 6 Sep 2013. 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 4 studies take place after a treatment is approved, to learn more about its long-term benefits and risks in everyday use.
Not every study follows the same path, and some studies (observational studies, device studies) have no phase.
Are results available for this study?
Yes. Results are posted in the registry (first posted 12 Apr 2012). A summary is in the For doctors view, and the full results are on ClinicalTrials.gov.
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?
Tenofovir Systemic Exposure During the Follicular Phase (Days 6-10 After Menses) (time frame: between time of dosing to 24 hours after dose administered). The study lists 8 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 6 Sep 2013; AzTrials last refreshed its copy on 8 Nov 2026.
