Clinical Trial Summary

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.


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.

Eligibility 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

- 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

Outcome

Type Measure Description Time frame Safety issue
Primary 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 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 Change in levels of mast cell progenitor-1 (MCP-1), IP-10, and HIV RNA in the cerebrospinal fluid (CSF) 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
Secondary Change in blood plasma levels of neopterin, interleukin-6, D-dimers, soluble cluster of differentiation 14 (sCD14), and soluble cluster of differentiation 163 (sCD163) 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
Secondary Change in absolute concentrations and ratios with respect to creatine of choline, myoinositol, and n-acetylaspartate (NAA) in specified brain regions These measurements will be made using magnetic resonance spectroscopy (MRS). Change from baseline to 48 weeks following ART initiation
Secondary Test scores on HIV neuropsychological battery 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
