About this study
Official title: A Phase I, Open-label, Randomized Cross-over, 2-period, 2-way Interaction Trial to Investigate the Pharmacokinetic Interaction Between Lopinavir/Ritonavir and TMC125 Both at Steady-state in Healthy Subjects.
The purpose of the study is to determine the effect of steady-state concentrations of LPV, co-administered with a low dose of ritonavir, on the steady-state pharmacokinetics of TMC125 and to determine the effect of steady-state concentrations of TMC125 on the steady-state pharmacokinetics of LPV, co-administered with a low dose of ritonavir.
Read the detailed description
This is a Phase I, open-label, randomized (patients are assigned different treatments based on chance), 2-period, 2-way cross-over interaction trial to investigate the pharmacokinetic interaction (study of the bodily absorption, distribution, metabolism, and excretion of drugs) between lopinavir/ritonavir (LPV/rtv) and TMC125, both at steady-state.The trial population will consist of 16 healthy volunteers. In 2 consecutive sessions, healthy volunteers will receive Treatment A and Treatment B, in a randomized sequence. In Treatment A, 200 mg TMC125 b.i.d.will be administered for 7 days (from Day 1 to Day 7) with an additional morning dose on Day 8. In Treatment B, 400/100 mgLPV/rtv twice a day will be administered for 15 days (from Day 1 to Day15) with an additional morning dose on Day 16, while 200 mgTMC125 b.i.d. will be co-administered from Day 9 to Day 15 with an additional morning dose on Day 16. Subsequent sessions will be separated by a washout period of at least 2 weeks. Full pharmacokinetic profiles of TMC125 will be determined over the 12-hour dosing interval after the morning intake on Day 8 of Treatment A and on Day 16 of Treatment B. Full pharmacokinetic profiles of LPV and ritonavir will be determined over the 12-hour dosing interval after the morning intake on Days 8 and 16 of Treatment B. All treatments will be administered under fed conditions and will be taken within 10 minutes after a meal. Safety and tolerability evaluations will be recorded continuously. Treatment A = 200 mg TMC125 b.i.d. will be administered for 7 days (from Day 1 to Day 7) with an additional morning dose on Day 8. Treatment B = 400/100 mg LPV/rtv b.i.d. will be administered for 15 days (from Day 1 to Day 15) with an additional morning dose on Day 16, while 200 mg TMC125 b.i.d. will be co-administered from Day 9 to Day 15 with an additional morning dose on Day 16.

Questions about this trial
What is this clinical trial studying?
A Phase 1 study testing Etravirine; Lopinavir; Ritonavir in people with HIV, 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 5 inclusion and 8 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?
Determine the effect of steady-state concentrations of LPV/low dose ritonavir, on the steady-state pharmacokinetics of TMC125 and vice versa.. 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.
