MARCH Renal Substudy (MARCHrenal)

January 18, 2016 updated by: Kirby Institute

Maraviroc Switch Collaborative Study Renal Substudy

Chronic kidney disease (CKD) is an emerging problem in patients with treated HIV. Antiretroviral therapy associated renal dysfunction has been predominantly described in terms of reduced glomerular filtration (eGFR). Proteinuria is a key component of CKD and may occur in the absence of significant reductions in eGFR. This substudy is an exploration of changes in urinary protein excretion in a randomised, open-label study to evaluate the efficacy and safety of MVC as a switch for either nucleoside or nucleotide analogue reverse transcriptase inhibitors (N(t)RTI) or boosted protease inhibitors (PI/r) in HIV-1 infected individuals with stable, well-controlled plasma HIV-RNA while taking their first N(t)RTI + PI/r regimen of combination antiretroviral therapy (cART).

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

The aim of this substudy of MARCH is to characterize the changes in protein and salt excretion through the kidney utilising the randomised arms of the parent study MARCH. The investigators hypothesize there will be an improvement in proteinuria in those switching to maraviroc containing regimens.

Study Type

Interventional

Enrollment (Actual)

76

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:

  • Provision of written, informed consent for participation in the substudy
  • Enrolled into the substudy either at or before the week 0 visit of the main study

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
Measure Description
Time Frame
changes in proteinuria and albuminuria between baseline and week 96
Time Frame: 96 weeks
To compare the change in protein and albumin excretion as measured by the urine PCR and ACR through the kidneys between the randomised and standard of care (control) arm of MARCH.
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
Measure Description
Time Frame
changes in renal tubular function between baseline and week 96
Time Frame: 96 weeks

To evaluate the following aspects of renal function at baseline and changes within and between study groups:

  • Tubular function defined as proximal tubular function; ascending thick loop of Henle; distal tubular function; volume and renal potassium handling;
  • Non-tubular function i.e. eGFR; Urine albumin:creatinine ratio;
  • Determine factors associated with renal dysfunction within the cohort e.g. demographics, HIV related, HIV-treatment related, co-morbidities, concomitant medication (such as ACE inhibitors and ARB; PI/r co-administered with TDF); TDF use;
96 weeks
