Analysis of Telmisartan Administered With Antiretroviral Therapy (ART) in Patients With Acute HIV Infection (SEARCH018)

March 4, 2020 updated by: Yale University

Adjunctive Therapy With Telmisartan Instituted With ART During Acute HIV Infection to Reduce the Establishment of Central Nervous System Reservoirs of HIV and Lymph Node Fibrosis [Southeast Asia Research Collaboration With Hawaii (SEARCH) 018]

This research project will study whether the drug telmisartan administered in conjunction with antiretroviral therapy (ART) will help reduce nervous system infection with HIV. The investigators are studying the effect of this treatment in people who have contracted HIV infection within the past three weeks, and thus have a form of HIV called acute HIV infection. The investigators will measure biological markers of immune activation in the blood and cerebrospinal fluid to see if telmisartan may reduce the spread of HIV reservoirs in affected patients.

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

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.

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.
No Intervention: Antiretroviral Therapy (ART) only
Acute HIV-infected subjects (n=7) will be randomly assigned to a group that will receive antiretroviral therapy (the current standard of care for HIV patients) for 72 weeks.
Experimental: ART + Telmisartan
Acute HIV-infected subjects (n=14) will be randomly assigned to a group that will receive treatment with telmisartan in addition to ART. Subjects will receive 40mg telmisartan daily for 4 weeks, followed by 80mg telmisartan daily for 44 weeks, to be taken in conjunction with ART. Subjects unable to tolerate 80mg of telmisartan will be able to de-escalate to 40mg daily. After telmisartan is stopped, subjects will continue to take ART for an additional 24 weeks (total 72 weeks).
Drug: Telmisartan

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
Change in level of neopterin in the cerebrospinal fluid (CSF) of patients placed on antiretroviral therapy (ART) administered in conjunction with telmisartan, versus those placed on ART only
Time Frame: Change from baseline to 48 weeks following ART initiation
Neopterin is a biological marker of immune activation. Its presence in the CSF provides information on the establishment and persistence of HIV viral reservoirs within the central nervous system of HIV-positive patients.
Change from baseline to 48 weeks following ART initiation

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
Change in levels of mast cell progenitor-1 (MCP-1), IP-10, and HIV RNA in the cerebrospinal fluid (CSF)
Time Frame: Change from baseline to 48 weeks following ART initiation
Will assess CSF levels of MCP-1, IP-10, and HIV RNA. Absolute levels of these compounds will be compared between subjects on ART + telmisartan versus those on ART only.
Change from baseline to 48 weeks following ART initiation
Change in blood plasma levels of neopterin, interleukin-6, D-dimers, soluble cluster of differentiation 14 (sCD14), and soluble cluster of differentiation 163 (sCD163)
Time Frame: Change from baseline to 48 weeks following ART initiation
Will assess blood plasma levels of these biomarkers in subjects on ART + telmisartan versus those on ART only.
Change from baseline to 48 weeks following ART initiation
Change in absolute concentrations and ratios with respect to creatine of choline, myoinositol, and n-acetylaspartate (NAA) in specified brain regions
Time Frame: Change from baseline to 48 weeks following ART initiation
These measurements will be made using magnetic resonance spectroscopy (MRS).
Change from baseline to 48 weeks following ART initiation
Test scores on HIV neuropsychological battery
Time Frame: Change from baseline to 48 weeks following ART initiation
The assessments to be used in this study have been tested for use with native Thai speakers and will be consistent with other SEARCH study tests. SEARCH employs a HIV neurocognitive battery designed to minimize cultural bias, which has been tested in Bangkok.
Change from baseline to 48 weeks following ART initiation
