About this study

Official title: A Study of the Pharmacokinetic and Pharmacodynamic Interactions Between Raltegravir (Isentress) and Buprenorphine

The main purpose of this protocol is to study the effect of an HIV medication known as Raltegravir on Buprenorphine in people who have been receiving the same dose of Buprenorphine for at least 3 weeks before study entry. This will be determined by giving Raltegravir along with Buprenorphine and by measuring the amount of Raltegravir and Buprenorphine in the blood. The investigators will also learn about the effects of Buprenorphine on Raltegravir and about the safety of taking these two medications together.

Read the detailed description

A large number of people who are infected with HIV have acquired it through injection drug use. Some of these people are currently being treated with Buprenorphine for their addiction and with medications for HIV infection. Raltegravir is a medication that was approved by the Food and Drug Administration (FDA) for the treatment of HIV infection. Raltegravir acts by making it more difficult for the virus that causes AIDS to multiply and cause more damage to the immune system in someone who is HIV infected.

Earlier studies looking at the effect of Buprenorphine and HIV medications have shown that Buprenorphine and some HIV medications act differently when taken together. It is important to learn if taking Buprenorphine and HIV medications together results in changes in the blood level of either medication. If the HIV medication affects the level of Buprenorphine in the blood, an individual taking Buprenorphine and HIV medications may experience symptoms of withdrawal, even while taking their usual dose of Buprenorphine. On the other hand, if Buprenorphine decreases the amount of HIV medication in the blood, then the HIV medication may be less effective in controlling HIV infection. It is therefore important to learn if Raltegravir and Buprenorphine will affect each other when taken together.

In order to learn about the effects of Buprenorphine and Raltegravir, we will need to measure the amount of Buprenorphine in your blood for 24 hours before you have taken Raltegravir and then compare that to the amount of Buprenorphine in your blood after you have taken Buprenorphine and Raltegravir together .

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • RaltegravirDrug

    Also called Isentress

    400 mg of raltegravir orally twice daily together with normally prescribed stable dose of buprenorphine for a minimum of 4 days and up to 14 days.

Study groups in NCT00858962
Study groupRoleWhat they receive
Bup/RalExperimentalBuprenorphine and Raltegravir co-administration
Receives: Drug: Raltegravir

What is being measured

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

  1. Area Under the Curve (AUC) of BUP/NLX With Raltegravir (hr*ng/mL)

    PK parameters of BUP were determined by non-compartmental methods. AUC of BUP was determined by use of the trapezoidal rule.

    Measured: 6-14 days after beginning co-administration of drugs

Questions about this trial

What is this clinical trial studying?

A study testing Raltegravir in people with HIV Infection and HIV Infections, run by Yale University 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 24 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 21 Nov 2012. 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.

Are results available for this study?

Yes. Results are posted in the registry (first posted 21 Nov 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?

Area Under the Curve (AUC) of BUP/NLX With Raltegravir (hr*ng/mL) (time frame: 6-14 days after beginning co-administration of drugs). 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 21 Nov 2012.
