Key requirements

Who can take part, as listed by the sponsor. Only the study team can confirm whether you are eligible, so take this list to your doctor.

  • Ages 18 to 55 years
  • All sexes
  • Healthy volunteers accepted
  • Adult

Who may be able to join

  • Subject is at least 18 and not older than 55 years at screening.
  • Subject does not smoke more than 10 cigarettes, 2 cigars, or 2 pipes per day for at least 3 months prior to Day 1.
  • Subject has a Quetelet Index (Body Mass Index) of 18 to 30 kg/m2, extremes included.
  • Subject is able and willing to sign the Informed Consent Form prior to screening evaluations.
  • Subject is in good age-appropriate health condition as established by medical history, physical examination, electrocardiography, results of biochemistry, haematology and urinalysis testing within 4 weeks prior to day 1. Results of biochemistry, haematology and urinalysis testing should be within the laboratory's reference ranges (see Appendix A). If laboratory results are not within the reference ranges, the subject is in-cluded on condition that the Investigator judges that the deviations are not clinically relevant. This should be clearly recorded.

About this study

Elvitegravir is an HIV-1 integrase inhibitor which is marketed in a fixed dose combination tablet with cobicistat, tenofovir and emtricitabine (Stribild®, referred to as STB). For patients with swallowing difficulties, administration of whole tablets can be problematic and tablets are cut or crushed to ease administration. In addition if HIV patients develop opportunistic infections, patients can become severely ill and may end up on the intensive care. Patients at the intensive care might not be able to swallow medication. Therefore it is useful to know if it is possible to administer STB through a different route, like a feeding tube. If STB can be crushed or dissolved and given through a catheter it is also useful to know if it can be given with drip feed.

Currently there is no information about crushing STB tablets. "Crushing STB tablets into a liquid medium has not been studied and is not recommended" according to the SPC text. Depending on the biopharmaceutical characteristics of a drug formulation, crushing tablets can lead to altered pharmacokinetics of drugs.

It is important to know whether pharmacokinetics are influenced by crushing of tablets as low concentrations are associated with virologic failure. Therefore higher doses might be needed. In addition, higher Cmax and/or exposure can lead to toxicity. As a result therapeutic drug monitoring is advised, or crushing the drug is a contra-indication based on the available data.

It has been shown that simultaneous oral ingestion of antacids and elvitegravir gives a decrease in Cmax and AUC of elvitegravir. This interaction is not shown for co-ingestion with omeprazole. Which makes it unlikely that this interaction is caused by a pH-lowering effect influencing the absorption of elvitegravir. It is probably a local gastrointestinal complexation phenomenon, similar to what has been observed with other HIV integrase inhibitors. A possible pharmacokinetic interaction between elvitegravir and complexation formers may be expected. Especially considering the active binding sites of elvitegravir which bind magnesium metal ion cofactors. Although there is data that STB can be ingested with a protein rich drink, it is unclear if foods or liquids containing high amounts of magnesium or other cations can cause this same interaction.

Therefore this study will be conducted to investigate whether crushed and suspended STB and crushed and suspended STB with drip feed are bioe-quivalent to taking STB as a whole.

Questions about this trial

What is this clinical trial studying?

A Phase 1 study testing Stribild and Stribild, crushed in people with HIV, run by Radboud University Medical Center at 1 site in Netherlands.

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 6 inclusion and 13 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 15 Mar 2021. 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?

AUC (time frame: up to 32 hours after administration). 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 NCT02325934, 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 15 Mar 2021.
