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.

Detailed Description

Note regarding the primary purpose of the study: In the Study Design section, this protocol is classified as "Other", since it is specifically designed to examine the effect of telmisartan administered in conjunction with ART on the size of HIV reservoirs in the central nervous system.

Description

Inclusion Criteria:

  • Age ≥ 18 years old
  • Have protocol-defined acute HIV-1 infection
  • Be part of the SEARCH 010/RV 254 study in Bangkok, Thailand
  • Ability and willingness to start ART immediately after diagnosis
  • Availability for follow-up for the duration of the planned study
  • Systolic blood pressure ≥ 110 mmHg
  • Agree to undergo lumbar puncture at weeks 0, 48 and 72

  • Known renal artery stenosis
  • Known cirrhosis or severe liver disease
  • Unstable coronary artery disease/angina or decompensated congestive heart failure
  • Any history of intolerance to any angiotensin receptor blocker
  • Need for ongoing potassium supplementation
  • Any contraindication to lumbar puncture such as history of bleeding diathesis or cerebral mass lesion

Design Details

  • Primary Purpose: Other
  • Allocation: Randomized
  • Interventional Model: Parallel Assignment
  • Masking: Double

Arms and Interventions

Participant Group / Arm
Intervention / Treatment
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).

What is the study measuring?

Primary Outcome Measures

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

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
