About this study
Patients with human immunodeficiency virus (HIV) and respiratory disease commonly require protease inhibitors (PIs) and orally inhaled corticosteroids. Inhaled corticosteroids alone do not generally cause systemic adverse effects because of low systemic bioavailability, but the combination of inhaled fluticasone and various PIs has led to increased systemic fluticasone levels and multiple cases of secondary adrenal insufficiency. A study in healthy volunteers showed > 350-fold increase in fluticasone area under the curve when ritonavir (RTV) 100mg twice daily was coadministered with intranasal fluticasone compared to intranasal fluticasone alone. The mechanism of this drug interaction is presumably secondary to PI inhibition of cytochrome P450 3A4, the enzyme responsible for fluticasone metabolism. As a result, inhaled fluticasone is not recommended in combination with most PIs unless the benefit outweighs the risk. One possible alternative to fluticasone is inhaled beclomethasone, which has not been studied in combination with PIs. Although beclomethasone also undergoes metabolism via CYP3A4 in vitro to its more active metabolite, beclomethasone-17-monopropionate, it appears to be largely hydrolyzed by esterases in vivo. Furthermore, the pharmacokinetic properties of beclomethasone-17-monopropionate, such as relatively short half-life, low maximum plasma concentration, and low volume of distribution, suggest that systemic accumulation leading to significant adverse effects is unlikely even in the presence of a CYP3A4 inhibitor such as a PI.
In this open-label study, 46 subjects will receive inhaled beclomethasone for 6 weeks from Days 1 to 42. Subjects will be randomized into 1 of 3 groups, such that from Days 15 to 42, 18 subjects will add no additional study drugs, 14 subjects will add RTV 100mg twice daily, and 14 subjects will add DRV/r 600/100mg twice daily. Pharmacokinetic sampling for beclomethasone and beclomethasone-17-monopropionate levels will occur on Days 14 and 28. Pre-cosyntropin cortisol levels and a low-dose adrenocorticotropic hormone (ACTH) stimulation test will be performed on all subjects on Days 1, 14, 28, and 42. Data from this investigation will determine whether RTV and/or DRV/r, potent CYP 3A4 inhibitors, alter the pharmacokinetics of beclomethasone and its active metabolite, beclomethasone-17-monopropionate (primary objective), and whether or not a possible increase in systemic bioavailability of beclomethasone and beclomethasone-17-monopropionate alters pre-cosyntropin cortisol levels and responses to ACTH stimulation test over a 4-week period (secondary objective). Results from this investigation will provide pharmacokinetic and pharmacodynamic data to assist clinicians in determining whether inhaled beclomethasone is an appropriate option in HIV-infected patients requiring concomitant therapy with an inhaled corticosteroid and PIs.

Questions about this trial
What is this clinical trial studying?
A Phase 1 study testing Darunavir, Ritonavir and Beclomethasone Dipropionate HFA in people with HIV and Asthma, run by National Institutes of Health Clinical Center (CC) 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 5 inclusion and 35 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 2 Jul 2017. 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 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.
What does the primary outcome measure?
Influence of Darunavir/Ritonavir and Ritonavir alone on the pharmacokinetics of inhaled Beclomethasone.. It is what the study was designed to measure, not a finding.
Where can I read the original study information?
On the ClinicalTrials.gov record for NCT00936793, which also lists 3 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 2 Jul 2017; AzTrials last refreshed its copy on 6 Nov 2026.
