About this study

Official title: Multicenter, Double-Blind, Randomized, Dose Ranging Study to Compare the Safety and Activity of MK0518 Plus Tenofovir and Lamivudine (3TC) Versus Efavirenz Plus Tenofovir and Lamivudine (3TC) in ART-Naive, HIV-Infected Patients

This is a study that will investigate the safety and efficacy of an investigational drug in Human immunodeficiency virus (HIV) infected patients.

Read the detailed description

Participants who completed 48 weeks of the original 48-week double-blind study were invited to continue in two extensions: MK0518-004-10 (NCT00100048), which extended the study to 144 weeks, and MK0518-004-20 (NCT00100048), which extended the study to 240 weeks. Participants who had been randomized to MK0518 in the base study continued at 400 mg MK0518 twice daily.

Participants randomized to efavirenz in the base study continued to receive efavirenz at the dosage given in the base study. The doses of open label tenofovir and lamivudine continued unchanged.

What is being measured

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

  1. Change From Baseline in Plasma Human Immunodeficiency Virus (HIV) Ribonucleic Acid (RNA) on Day 10 (Cohort I)

    Mean change from baseline on Day 10 in plasma Human Immunodeficiency Virus (HIV) Ribonucleic acid (RNA) (copies/mL)

    Measured: Baseline and Day 10

  2. Number of Patients With Clinical Adverse Experiences (CAEs) and Number of Patients With Serious CAEs at Day 10 (Cohort I)

    An adverse experience (AE) is defined as any unfavorable and unintended change in the structure, function, or chemistry of the body temporally associated with the use of the SPONSOR'S product, whether or not considered related to the use of the product.

    Serious CAEs are any AEs occurring at any dose that; Results

    in death; or Is life threatening; or Results in a persistent or significant disability/incapacity; or Results in or

    prolongs an existing inpatient hospitalization; or Is a congenital anomaly/birth defect; or Is a cancer; or Is an

    overdose.

    Measured: 10 days

  3. Number of Participants With HIV RNA Levels Below 400 Copies/mL at Week 24 (Cohort II)

    Measured: Week 24

  4. Number of Patients With Clinical Adverse Experiences (CAEs)

    An adverse experience (AE) is defined as any unfavorable and unintended change in the structure, function, or chemistry of the body temporally associated with the use of the SPONSOR'S product, whether or not considered related to the use of the product.

    Measured: 48 weeks

  5. Number of Patients With Serious CAEs (Cohort I and II Combined)

    Serious CAEs are any AEs occurring at any dose that; Results in death; or Is life threatening; or Results in a persistent or significant disability/incapacity; or Results in or prolongs an existing inpatient hospitalization; or Is a congenital anomaly/birth defect; or Is a cancer; or Is an overdose

    Measured: 48 weeks

  6. Number of Patients With Serious CAEs and Non-serious CAEs at Week 144

Questions about this trial

What is this clinical trial studying?

A Phase 2 study testing Comparator: MK0518 monotherapy, Comparator: MK0518 combination therapy and Comparator: efavirenz in people with HIV Infections and Acquired Immunodeficiency Syndrome, run by Merck Sharp & Dohme LLC.

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 2 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 Sep 2015. 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. Some participants in this study may receive a placebo. 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 29 Mar 2010). 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?

Change From Baseline in Plasma Human Immunodeficiency Virus (HIV) Ribonucleic Acid (RNA) on Day 10 (Cohort I) (time frame: Baseline and Day 10). 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 NCT00100048, which also lists 4 linked publications.

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 Sep 2015.
