About this study

Official title: A Single-Dose, Open-Label, Randomized, Replicate Crossover Pivotal Bioequivalence Study in Healthy Adult Participants to Assess the Bioequivalence of Darunavir 675 mg, Emtricitabine 200 mg, and Tenofovir Alafenamide 10 mg in the Presence of Cobicistat 150 mg When Administered as a Fixed Dose Combination (Darunavir/Cobicistat/Emtricitabine/Tenofovir Alafenamide) Compared to the Co-administration of the Separate Agents (Darunavir, Cobicistat, and Emtricitabine/Tenofovir Alafenamide), Under Fed Conditions

The purpose of the study is to evaluate the single-dose pharmacokinetics (PK) and pivotal bioequivalence of 3 compounds Darunavir (DRV), emtricitabine (FTC), and tenofovir alafenamide (TAF) in the presence of cobicistat (COBI) when administered as an fixed dose combination (FDC) (Darunavir/Cobicistat/Emtricitabine/Tenofovir Alafenamide [D/C/F/TAF]) compared to the co-administration as the separate commercial formulations (DRV and F/TAF and COBI), under fed conditions, in healthy adult participants.

What is being measured

The primary outcome is the main question the study is designed to answer.

Maximum Observed Analyte Concentration (Cmax) of Darunavir, Emtricitabine and Tenofovir Alafenamide
Cmax is the maximum observed analyte concentration.
Measured: Up to 72 hours post-dose
Area Under the Analyte Concentration-time Curve from time Zero to Last Quantifiable time (AUC[0-last]) of Darunavir, Emtricitabine and Tenofovir Alafenamide
AUC(0-last) is the area under the analyte concentration-time curve from time zero to the time of the last measurable (non-below quantification limit [non-BQL]) concentration, calculated by linear-linear trapezoidal summation.
Measured: Up to 72 hours post-dose

Secondary outcomes (4)

Area Under the Analyte Concentration-time Curve From Time Zero to Infinite Time (AUC[0-infinity]) of Darunavir, Cobicistat, Emtricitabine and Tenofovir Alafenamide
AUC (0-infinity) is the area under the analyte concentration-time curve from time zero to infinite time, calculated as the sum of AUC(0-last) and C(last)/lambda(z); wherein AUC(0-last) is area under the analyte concentration-time curve from time zero to last quantifiable time, C(last) is the last observed measurable concentration, and lambda(z) is elimination rate constant.
Measured: Up to 72 hours post-dose
Cmax of Cobicistat
Cmax is the maximum observed analyte concentration of Cobicistat.
Measured: Up to 72 hours post-dose
AUC(0-last) of Cobicistat
AUC(0-last) is the area under the analyte concentration-time curve from time zero to the time of the last measurable (non-BQL) concentration, calculated by linear-linear trapezoidal summation.
Measured: Up to 72 hours post-dose
Number of Participants with Adverse Events (AEs)
An AE is any untoward medical occurrence in a participant participating in a clinical study that does not necessarily have a causal relationship with the pharmaceutical/biological agent under study.
Measured: Up to 9 weeks

Questions about this trial

What is this clinical trial studying?

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 9 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 3 Feb 2025. 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 Netherlands. 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?

Maximum Observed Analyte Concentration (Cmax) of Darunavir, Emtricitabine and Tenofovir Alafenamide (time frame: Up to 72 hours post-dose). The study lists 2 primary outcomes in all. 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 NCT04661397, which also lists 1 linked publication.

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 3 Feb 2025.
