About this study

Official title: A Phase II, Open-label Trial, to Investigate Pharmacokinetics, Safety, Tolerability and Antiviral Activity of TMC114/Rtv b.i.d in Treatment-Experienced HIV-1 Infected Children and Adolescents

The purpose of this study is to evaluate the pharmacokinetics (the study of the way a drug enters and leaves the blood and tissues over time), safety, tolerability and antiviral activity to support dose recommendations of TMC114 with ritonavir and other antiretroviral agents in treatment-experienced, human immunodeficiency virus (HIV)-1 infected children and adolescents.

Read the detailed description

This is an open-label (all people know the identity of the intervention) and randomized (study drug assigned by chance) study to evaluate pharmacokinetics, safety, tolerability, efficacy, antiviral activity, immunology and resistance characteristics of TMC114 with ritonavir in treatment-experienced, HIV-1 infected children and adolescent participants. The study consists of 3 periods: Screening period (maximum 4 weeks); Treatment period (maximum 48 weeks); and Follow-up period (4 weeks). The Treatment period consists of two parts: Part-1 for pediatric dose selection and Part-2 for the recommendation of pediatric or adult dose. Part-1 was further divided into two groups: Group A with adult equivalent dose of TMC114 with ritonavir twice daily and Group B with 20-33 percent higher dose of TMC114 with ritonavir twice daily. The recommended dose will be selected based on short-term safety, tolerability, antiviral activity and pharmacokinetics at Week 2. Once selected, all Part-1 participants who will not be on the selected dose will be switched to the selected dose at their next visit and will continue the study up to 48 weeks in Part-2. Participants with less than or equal to 18 years at Week 48 visit, and continued to benefit from treatment with TMC114 and will be living in a country where TMC114 pediatric use is not yet part of the label, will have the opportunity to roll-over to the extension phase where they will continue to receive TMC114/ritonavir until the participant became 18 years and TMC114 will be available through the local Health Care Systems or until TMC114 is indicated for use in pediatrics. Efficacy will primarily be evaluated by virologic response. Participants' safety will be monitored throughout the study.

What is being measured

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

  1. Area Under the Plasma Concentration-Time Curve From Time of Administration to 12 hours After Dosing (AUC 0-12h) - Part 1

    The Area Under the Plasma Concentration-Time Curve (AUC) is a measure of the plasma concentration of the drug over time. It is used to characterize drug absorption.

    Measured: Week 2

  2. Predose Plasma Concentration (C0) - Part 1

    The C0 is the predose plasma concentration.

    Measured: Week 2

  3. Maximum Observed Plasma Concentration (Cmax) - Part 1

    The Cmax is the maximum observed plasma concentration.

    Measured: Week 2

  4. Recommended Dose of TMC114 per Body Weight

    The recommended dose of TMC114 will be determined in participants with a body weight: greater than and equal to 20 Kilogram (kg) to less than 30 kg; greater than and equal to 30 kg to less than 40 kg; and greater than 40 kg.

    Measured: Week 2

  5. Change From Baseline in Plasma Viral Load at Week 2 - Part 1

    Plasma viral load levels will be determined using Roche amplicor human immunodeficiency virus (HIV)-1 monitor test (Version 1.5).

    Measured: Baseline and Week 2

  6. Change From Baseline in Plasma Viral Load at Week 24- Part 2

    Plasma viral load levels will be determined using Roche amplicor HIV-1 monitor test (Version 1.5).

    Measured: Baseline and Week 24

  7. Number of Participants With Adverse Events

    Adverse event is defined as any untoward medical occurrence in a participant or clinical investigation participant administered with a pharmaceutical product and which does not necessarily have a causal relationship with the treatment.

    Measured: Week 2

  8. Number of Participants With Adverse Events

    Adverse event is defined as any untoward medical occurrence in a participant or clinical investigation participant administered with a pharmaceutical product and which does not necessarily have a causal relationship with the treatment.

    Measured: Week 24

Secondary outcomes (6)
  1. Change From Baseline in Plasma Viral Load at Week 48 - Part 2

    Plasma viral load levels will be determined using Roche amplicor HIV-1 monitor test (Version 1.5).

    Measured: Baseline and Week 48

  2. Change from Baseline in Cluster of Differentiation 4 (CD4+) cell count - Part 2

    The immunologic change will be determined by changes in CD4+ cell count.

    Measured: Baseline and Week 48

  3. Number of Participants With Resistance - Part 2

    Resistance will be determined by viral phenotype and genotype determinations, which will be performed by Virco BVBA, by means of the antivirogram and Virco type HIV-1 respectively. Resistance determinations will only be generated if the viral load is greater than 1000 HIV-1 RNA copies/milliliter.

    Measured: Week 48

  4. Area Under the Plasma Concentration-Time Curve From Time of Administration to 12 hours After Dosing (AUC 0-12h) - Part 2

    The Area Under the Plasma Concentration-Time Curve (AUC) is a measure of the plasma concentration of the drug over time. It is used to characterize drug absorption.

    Measured: Week 48

  5. Predose Plasma Concentration (C0) - Part 2

    The C0 is the predose plasma concentration.

    Measured: Week 48

  6. Oral Clearance (CL/F) - Part 2

    The CL/F is the oral clearance; that is clearance based on oral bioavailability.

    Measured: Week 48

Questions about this trial

What is this clinical trial studying?

A Phase 2 study testing TMC114 and Ritonavir in people with HIV-1 and HIV Infections, run by Tibotec Pharmaceuticals, Ireland at 22 sites in 8 countries.

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 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 8 Jul 2013. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 22 sites in United States, Brazil, South Africa, Canada, Romania and 3 more countries. 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?

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?

Area Under the Plasma Concentration-Time Curve From Time of Administration to 12 hours After Dosing (AUC 0-12h) - Part 1 (time frame: Week 2). The study lists 8 primary outcomes in all. 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 NCT00355524, 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 8 Jul 2013.
