The Safety and Effectiveness of Lamivudine Plus Stavudine or Zidovudine in HIV-Infected Patients Who Have Taken Zidovudine

April 28, 2011 updated by: Bristol-Myers Squibb

A Randomized Double-Blind Study of Safety, Virologic and Immunological Effects of Stavudine Plus Lamivudine (3TC) Versus Zidovudine Plus Lamivudine in HIV-Infected Subjects Following At Least Six Months of Zidovudine Therapy

To compare the magnitude and durability of the reduction in plasma HIV RNA in the two treatment groups over the first 12 weeks of treatment. To determine the safety of each of the two treatment groups.

Study Overview

Status

Status

Indicates the current recruitment status or the expanded access status.
Completed

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Detailed Description

Patients will be randomized to either Stavudine (d4T) + Lamivudine (3TC) + Zidovudine placebo or Zidovudine (ZDV) + Lamivudine + Stavudine placebo. Patients whose plasma HIV RNA levels remain >= 500 copies/ml after 8 weeks of blinded double combination therapy will have indinavir added to their treatment regimen at the week 12 visit.

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

18 years and older (Adult, Older Adult)

Accepts Healthy Volunteers

No

Genders Eligible for Study

All

Description

Inclusion Criteria

Patients must have:

  • At least six months of prior cumulative ZDV therapy.
  • Qualifying plasma HIV RNA count of >= 4 log10 copies/ml obtained within 2 weeks of randomization.

Exclusion Criteria

Co-existing Condition:

Patients with any of the following symptoms or conditions are excluded:

  • Presence of newly diagnosed AIDS defining opportunistic infection requiring acute therapy at time of enrollment.
  • Intractable diarrhea (>= 6 loose stools/day for >= 7 consecutive days).
  • Signs and symptoms of bilateral peripheral neuropathy >= grade 2 at the time of screening.
  • Inability to tolerate oral medication.
  • Any other clinical conditions that in the opinion of the investigator, would make the patient unsuitable for study or unable to comply with the dosing requirements.

Concurrent Medication:

Excluded:

  • Therapy with agents with systemic myelosuppressive, neurotoxic pancreatotoxic, hepatotoxic or cytotoxic potential.
  • Therapy with rifampin, rifabutin, terfenadine, astemizole, cisapride, triazolam, midazolam and ketoconazole at any time while on indinavir therapy.

Patients with any of the following prior conditions or symptoms are excluded:

  • History of acute or chronic pancreatitis.
  • Prior history of bilateral peripheral neuropathy.
  • Intractable diarrhea (>= 6 loose stools/day for >= 7 consecutive days) within 30 days prior to study entry.

Prior Medication:

Excluded:

  • Any prior antiretroviral therapy except for ddI, ddC, 3TC or ZDV (for ZDV, as specified in inclusion criteria).
  • Previous therapy with agents with significant systemic myelosuppressive, neurotoxic pancreatotoxic, hepatotoxic or cytotoxic potential within 3 months of study start.
  • Therapy with rifampin, rifabutin, terfenadine, astemizole, cisapride, triazolam, midazolam and ketoconazole within 2 weeks prior to starting indinavir.
  • Any other prior therapy that, in the opinion of the investigator, would make the patient unsuitable for study or unable to comply with the dosing regimen.

Risk Behavior:

Excluded:

  • Active alcohol abuse, sufficient in the investigator's opinion, to prevent compliance with study therapy or to increase the risk of developing pancreatitis.

Required:

At least 6 months of prior cumulative ZDV therapy.

Study record dates

These dates track the progress of study record and summary results submissions to ClinicalTrials.gov. Study records and reported results are reviewed by the National Library of Medicine (NLM) to make sure they meet specific quality control standards before being posted on the public website.

Study Major Dates

Study Start

Study Start

The actual date on which the first participant was enrolled in a clinical study. The "anticipated" study start date is the date that the researchers think will be the study start date.
June 1, 1996

Primary Completion (Actual)

Primary Completion

The date on which the last participant in a clinical study was examined or received an intervention to collect final data for the primary outcome measure. Whether the clinical study ended according to the protocol or was terminated does not affect this date. For clinical studies with more than one primary outcome measure with different completion dates, this term refers to the date on which data collection is completed for all the primary outcome measures. The "anticipated" primary completion date is the date that the researchers think will be the primary completion date for the study.

Study Completion (Actual)

Study Completion

The date on which the last participant in a clinical study was examined or received an intervention/treatment to collect final data for the primary outcome measures, secondary outcome measures, and adverse events (that is, the last participant's last visit). The "anticipated" study completion date is the date that the researchers think will be the study completion date.
