About this study

Official title: A Phase IIa, Open-label, Randomized Trial in Treatment-naive HIV-1-infected Subjects to Determine the Antiviral Activity of 14 Days of Monotherapy With 4 Different Dose Regimens of TMC310911 Coadministered With Ritonavir

The purpose of this study is to evaluate the antiviral activity as measured by the change in viral load from baseline in the 14 days following initiation of treatment with 4 different dose regimens of TMC310911 co-administered with ritonavir.

Read the detailed description

This is an open-label (all people know the identity of the intervention) and randomized (study medication assigned by chance) study in treatment-naive human immunodeficiency virus type 1 (HIV-1)-infected participants (participants who had not been treated with a therapeutic HIV vaccine within 1 year prior to enrollment and who had never been treated with an antiretroviral [ARV] medication indicated for the treatment of HIV-infection or ARVs for treatment of hepatitis B infection with anti-HIV activity prior to screening). In this study approximately 32 participants will be enrolled and randomly assigned to receive 4 different dose regimens co-administered with ritonavir (8 participants in each dosing regimen). The trial will consist of a screening period (maximum 6 weeks), a treatment period with TMC310911 (2 weeks), and a follow-up period (4 weeks). Safety evaluation will include assessment of adverse events, clinical laboratory tests, vital sign measurements, physical examinations and electrocardiograms.

What is being measured

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

  1. Mean Changes From Baseline in Plasma log10 Human Immunodeficiency Virus Type 1 Ribonucleic Acid (HIV-1 RNA)

    The antiviral activity of TMC310911 is measured by the change in viral load from baseline in the 14 days of treatment following initiation of treatment with 4 different dosing regimens of TMC310911 coadministered with ritonavir.

    Measured: Baseline (Day 1), Day 8, Day 15

Secondary outcomes (8)
  1. Number of Participants With Virologic Response at Any Timepoint During the 14-day Treatment Period

    Virologic response is a viral load test result below a chosen threshold value (less than 50 copies/mL, less than 400 copies/mL, or at least 1 log drop in viral load) at any timepoint during a 14-day treatment of 4 different dose regimens of TMC310911 coadministered with 100 mg ritonavir.

    Measured: 14 days

  2. Mean Changes From Baseline in CD4+ Cell Count

    Measured: Baseline (Day 1), Day 8, Day 15

  3. Maximum Plasma Concentration (Cmax) of TMC310911

    Measured: Day 1 and Day 14

  4. Time to Reach the Maximum Plasma Concentration (Tmax) of TMC310911

    Measured: Day 1 and Day 14

  5. Area Under the Plasma Concentration-time Curve (AUC12) From the Time of Administration of TMC310911 up to 12 Hours After Dosing

    Measured: Day 1 and Day 14

  6. Predose Plasma Concentration (C0h) of TMC310911

    Measured: Day 2, Day 3, Day 4, Day 6, Day 8, Day 10, Day 12 and Day 14

  7. Average Steady-state Plasma Concentration (Css,av) of TMC310911

    Measured: Day 14

  8. Fluctuation Index of TMC310911

    Fluctuation index, ie, percentage fluctuation: variation between maximum (Cmax) and minimum (Cmin) plasma concentration at steady-state, calculated as: 100 x ([Cmax-Cmin]/Css,av). Css,av is an average steady-state plasma concentration.

    Measured: Day 14

Questions about this trial

What is this clinical trial studying?

A Phase 2 study testing TMC310911 75 mg twice daily, TMC310911 150 mg twice daily and TMC310911 300 mg twice daily in people with Human Immunodeficiency Virus Type 1, run by Tibotec Pharmaceuticals, Ireland at 3 sites in Germany.

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 7 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 12 Jun 2013. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 3 sites in Germany. 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 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

Are results available for this study?

Yes. Results are posted in the registry (first posted 7 Mar 2013). 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?

Mean Changes From Baseline in Plasma log10 Human Immunodeficiency Virus Type 1 Ribonucleic Acid (HIV-1 RNA) (time frame: Baseline (Day 1), Day 8, Day 15). 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 12 Jun 2013.
