TMC125-TiDP2-C188: A Phase I, Open-label Trial to Investigate the Pharmacokinetic Effect of Multiple-dose TMC125 on Buprenorphine and Norbuprenorphine Administered in HIV-negative Patients on Stable Buprenorphine/Naloxone Maintenance Therapy.
A Phase 1 study testing TMC125 in people with HIV and Pharmacokinetics, run by Tibotec Pharmaceuticals, Ireland.
Trial summary
TMC125 is from the class of drugs called non-nucleoside reverse transcriptase inhibitors (NNRTIs). NNRTIs work by blocking reverse transcriptase, a protein that HIV needs to make more copies of itself. TMC125 is used in the treatment of adults with HIV-1 infection. Read more about this study

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
- No healthy volunteers
- Adult
Who may be able to join
- Body Mass Index (BMI) of 18.0 to 30.0 kg/m2, extremes included. BMI is calculated as the weight (in kg) divided by the square of height (in m)
- Receiving once daily buprenorphine/naloxone maintenance therapy at a stable individualized dose formulated and administered as sublingual tablets with a maximum daily dose of 16/4 mg of buprenorphine/naloxone. Patients using buprenorphine only are also eligible if they switch to buprenorphine/naloxone minimally 2 weeks before randomization
- The patient agrees not to change the current buprenorphine/naloxone therapy from Screening until Day 14 included (switching buprenorphine to buprenorphine/naloxone between Screening and Day -14 is allowed)and to have a daily observed and documented buprenorphine/naloxone intake from Day -14 until Day 15

About this study
Official title: A Phase I, Open-label Trial to Investigate the Pharmacokinetic Effect of Multiple-dose TMC125 on Buprenorphine and Norbuprenorphine Administered in HIV-negative Subjects on Stable Buprenorphine/Naloxone Maintenance Therapy.
TMC125 is from the class of drugs called non-nucleoside reverse transcriptase inhibitors (NNRTIs). NNRTIs work by blocking reverse transcriptase, a protein that HIV needs to make more copies of itself. TMC125 is used in the treatment of adults with HIV-1 infection. The purpose of this trial is to see if there is any potential interaction (change in the effectiveness of the drug) when taking multiple-dose TMC125 and buprenorphine/naloxone together. The trial will also assess the short-term safety and tolerability (how well your body handles the drug) when TMC125 and buprenorphine/naloxone are taken together.
Read the detailed description
This is a Phase I, open-label (patient and trial doctor know what medication you are taking at any point in time during the trial), add-on trial in patients who are on stable sublingual (placed in the mouth under the tongue until it disolves) buprenorphine/naloxone maintenance therapy, to investigate the potential pharmacokinetic effect of multiple-dose TMC125 on buprenorphine and norbuprenorphine administered as buprenorphine/naloxone. The study population will consist of 16 HIV-negative opioid-dependent patients on stable individualized sublingual buprenorphine/naloxone maintenance therapy. Patients will first participate in a 2 weeks run-in period with supervised buprenorphine/naloxone intake. Subsequently, patients will receive TMC125 200 mg orally twice daily for 14 days added to their buprenorphine/naloxone treatment. During the treatment period from Day 1 to Day 14, the individualized buprenorphine/naloxone treatment will be continued with co-administration of TMC125. Full pharmacokinetic profiles of buprenorphine and norbuprenorphine will be determined on Days -1 and 14 up to 24 hours postdose. Full pharmacokinetic profiles of TMC125 will be determined on Day 14 up to 12 hours postdose. Pharmacodynamic assessments of symptoms of opiate withdrawal and excess will be performed. The short-term safety and tolerability will be assessed throughout the trial. Patients will firstparticipate in a 2 weeks run-in period with supervised buprenorphine/naloxone intake. Subsequently, patients will receive 2 tablets of 100 mg TMC125 twice daily for 14 days added to their buprenorphine/naloxone treatment. During the treatment period from Day 1 to Day 14, the individualized buprenorphine/naloxone treatment will be continued with co-administration of TMC125.

Questions about this trial
What is this clinical trial studying?
A Phase 1 study testing TMC125 in people with HIV and Pharmacokinetics, run by Tibotec Pharmaceuticals, Ireland.
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 5 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 9 Jun 2011. Status can change between updates, so confirm with the study contact before making plans.
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?
The primary objective is to determine the effect of multiple-dose TMC125 on the steady-state pharmacokinetics of buprenorphine and its metabolite norbuprenorphine in HIV-negative patients during 2 weeks.. 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 9 Jun 2011.
