April 5, 2013 updated by: Ines Perez

Análisis de Los Cambios en el Tejido Adiposo de Pacientes Con infección VIH y Lipoatrofia en Tratamiento Con análogos de nucleósidos timidínicos, Tras el Cambio a Monoterapia Con Lopinavir/Ritonavir

The objective is to analyse the changes in the adipose tissue hystological features and the adipogenesis gene expression and related to inflammation after 48 and 96 weeks after the change from AZT+3TC+ABC (Trizivir®) to a monotherapy treatment with LPV/r (Kaletra®)

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.

Study Type

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 infected with VIH-1, documented with a positive HIV-1 antibody test and/or positive PCR, confirmed for HIV-1 RNA.
  • Patients treated with a HAART that should contain AZT+3TC+ABC (Trizivir®)
  • Patients with an indetectable viral load, which will be defined <40 copies/mL within the last six months.
  • Patients with a lipoatrophy clinical evidence (which will be defined as moderate or severe, according to the Lipodystrophy Severity Grading Scale).
  • Men or women aged ≥ 18.
  • For women of childbearing potential, negative urine pregnancy test during the Screening visit.
  • Patients that have signed and dated the Informed consent Form prior to any Study-specific procedure.

Exclusion Criteria:

  • Patients with evidence of protease inhibitors failure, and/or documented evidence of protease gene resistance mutation. This evidence could be prior or during the inclusion period in the Study.
  • Patients who, for any reason could not be treated with LPV/r.
  • Cachexia, defined as an Body Mass Index <17 Kg/m2.
  • Pregnant or breastfeeding women, or women of childbearing potential who do not use the appropriate contraceptive method, according to the Investigator judgment.
  • Clinically relevant disease or condition, according to the Investigator judgment, three months prior to the patient inclusion in the Study.
  • Patients taking the following concomitant medication that could affect the adipocyte function or morphology, such as: insulin, steroids, anabolic steroid, anti-inflammatory medication for more than three months.

Arms and Interventions

Participant Group / Arm

Participant Group / Arm

A group or subgroup of participants in a clinical trial that receives a specific intervention/treatment, or no intervention, according to the trial's protocol.
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.
Experimental: Kaletra, all patients
Patients will change actual treament for monotherapy LPV/r. They only will take Kaletra 2/day

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Time Frame
Change in those representative gene expression of adipose tissue toxicity (variable established from those gene involved in adipogenesis, inflammation and metabolism. This gene expression will counted)
Time Frame: 48 and 96 weeks
48 and 96 weeks

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Time Frame
Changes in physical fat deposits
Time Frame: Baseline, 24, 48, 72 and 96 weeks
Baseline, 24, 48, 72 and 96 weeks

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.
