Clinical Trial Summary

Despite treatment with antiretroviral therapy, women living with HIV continue to experience cognitive impairment. Psychological risk factors, including stress, impair cognition more in HIV-infected women than HIV-uninfected women. This study plans to examine a novel intervention for cognitive dysfunction that targets the mechanisms by which stress negatively affects cognitive functioning.

Description:

The overall aim of this study is to contribute important foundational knowledge of the utility of targeting neuroinflammation and the hypothalamic-pituitary-adrenal (HPA) axis to improve cognition in HIV and will provide key clinical insights into the mechanisms underlying any cognitive benefit. The investigators are conducting a single-dose study of low dose hydrocortisone (LDH) followed by a 4-week study of daily LDH as a probe of the mechanisms of neuroinflammation including myeloid-lineage cells and the HPA axis in HIV-infected (HIV+) women demonstrating cognitive dysfunction and reporting high levels of stress, trauma history, and mental health risk factors which commonly occur in this population. The use of a pharmacological challenge may aid in the identification of: 1) a putative biomarker of stress- and psychiatric disorder-related neurocognitive complications in HIV-infected women and/or 2) an adjunctive, cost-effective therapy for the treatment of cognitive deficits in HIV

The design is a two-phase study of HIV+ women who: 1) first participate in a double-blind, placebo-controlled cross-over study of a single, low dose (10 mg) of hydrocortisone versus placebo on cognition; and 2) then participate in a mechanistic, randomized, double-blind, placebo controlled trial of daily LDH for 4 weeks on cognition and side effects. The clinical trial will include 100 virally suppressed HIV+ women who show elevated stress and cognitive impairment and who represent the range of psychological risk factors characteristic of this population. Next, to understand the mechanism and broader clinical significance of LDH on cognition, investigators will conduct a 4-week randomized study of the effects of daily treatment with LDH versus placebo on cognition in HIV+ women (targeted n=80).

Women meeting enrollment criteria will complete three cognitive assessments. The first and second assessments will be embedded in the double-blind, placebo-controlled, cross-over study of a single administration of LDH versus placebo (targeted n=100). Investigators will measure cognitive performance 30 minutes and 4 hours post-dosing, because an emerging literature shows that the cognitive effects of LDH depends on timing of the assessment post-dosing. The 30-minute assessment addresses how the maximal cortisol levels following LDH affect cognition. This immediate assessment is standard in studies of stress and cognition and allows for comparisons with the broader literature. More novel and clinically important is the 4-hour assessment which occurs post-peak, when cortisol levels are more steady state and typical of the broader daily cortisol profile following LDH. The third assessment will take place after 4 weeks of treatment with LDH or placebo. That assessment addresses the clinical significance and safety of longer-term LDH treatment. Lastly, the investigators will explore glucocorticoids and inflammation and immune activation as mechanisms by which LDH might affect cognition.

Objective 1 To examine immediate and delayed effects of a single administration of LDH on cognition in HIV+ women.

Objective 2 To examine the effects of a 4-week course of daily LDH on cognition in HIV+ women.

Objective 3 To investigate potential mechanisms of LDH effects on cognition in HIV+ women.

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Hopkins Verbal Learning Test-Revised assesses total learning	a 12-item list-learning task across 3 trials used to measure total learning. Outcome=total learning across trials (range 0-36). Neuropsychological measures are normed on populations and therefore the clinical significance of a score can be assessed in relation to expected levels of performance.	change between baseline and 28 days
Primary	Hopkins Verbal Learning Test-Revised assesses verbal memory	following the 3 learning trials there is a 20-25 minute delay. After the delay, participants are asked to recall as many words as they can from the initial learning list. Outcome=delayed free recall (range 0-12).Neuropsychological measures are normed on populations and therefore the clinical significance of a score can be assessed in relation to expected levels of performance.	change between baseline and 28 days
Primary	Wechsler Adult Intelligence Scale IV Letter-Number Sequencing assesses working memory condition	participants hear a series of letters and numbers, and then recite them back in ascending order, with the numbers first and then the letters. Outcome=total correct (range 0-24). Neuropsychological measures are normed on populations and therefore the clinical significance of a score can be assessed in relation to expected levels of performance.	change between baseline and 28 days
Primary	Repeatable Battery for the Assessment of Neuropsychological Status (RBANS) Line Orientation Task assesses visuospatial abilities	In each of 10 trials, a visual array of 13 lines fans out from a common point of origin. Two target lines are shown beneath each array, and participants must identify the lines within the array that match each of the two target lines. Outcome=Total correct (range=0-20).	change between baseline and 28 days
Secondary	Trail Making Test Part A assesses processing speed/attention	25 circles distributed over a sheet of paper. The circles are numbered 1 - 25 and the participant should draw lines to connect the numbers in ascending order. Outcome=Time to completion (range: 10 to 300 seconds). Neuropsychological measures are normed on populations and therefore the clinical significance of a score can be assessed in relation to expected levels of performance.	change between baseline and 28 days
Secondary	Trail Making Test Part B assesses mental flexibility	25 circles are distributed over a sheet of paper. Circles include both numbers (1 - 13) and letters (A - L). The participant draws lines to connect the circles in an ascending pattern, but with the added task of alternating between the numbers and letters (i.e., 1-A-2-B-3-C, etc.). Outcome=time to completion (range: 18-300). Neuropsychological measures are normed on populations and therefore the clinical significance of a score can be assessed in relation to expected levels of performance.	change between baseline and 28 days
Secondary	Comalli Stroop Test, Trial 1 assesses processing speed/attention	Participants identify aloud the colors of a series of squares. Outcome=time to completion (range: 30 to 240). Neuropsychological measures are normed on populations and therefore the clinical significance of a score can be assessed in relation to expected levels of performance.	change between baseline and 28 days
Secondary	Comalli Stroop Test, Trial 2 assesses processing speed/attention	Participants read a series of color names printed in black ink. Outcome=time to completion (range: 30 to 240). Neuropsychological measures are normed on populations and therefore the clinical significance of a score can be assessed in relation to expected levels of performance.	change between baseline and 28 days
Secondary	Comalli Stroop Test, Trial 3 assesses behavioral inhibition	Participants name the color of the ink but ignore the word. Outcome=time to completion (range: 50 to 240). Neuropsychological measures are normed on populations and therefore the clinical significance of a score can be assessed in relation to expected levels of performance.	change between baseline and 28 days
