Study Description

Brief Summary:

There is still no cure for the human immunodeficiency virus (HIV). While combination antiretroviral therapy (cART) is effective in decreasing deaths from HIV, infected individuals face a lifetime of treatment and many potential complications including end organ diseases such as HIV-associated neurocognitive disorders. HIV infection is controllable with antiretroviral therapy (ART), but ART cannot eliminate HIV reservoirs. Thus, there is no available cure for HIV. There is a large and growing body of evidence that the central nervous system (CNS) is an HIV reservoir site and a barrier to HIV eradication. Our group has done extensive pre-clinical work with janus-kinase (JAK 1/2) inhibitors. This includes baricitinib, which is an orally available, FDA-approved drug for rheumatoid arthritis. Evidence suggests that this drug has activity against HIV in the central nervous system (CNS). In our recently completed pilot study, we showed that baricitinib crosses the blood brain barrier (BBB) and decreases HIV CNS persistence in the brain.

Using bloodwork, neurocognitive testing, MRIs and lumbar punctures, we plan to evaluate the change in central nervous system HIV after treatment with baricitinib versus placebo. We will also evaluate changes in neuroimaging, inflammation in blood and cerebrospinal fluid (CSF), and neuropsychological performance after treatment with baricitinib versus placebo.

Evidence shows that the central nervous system is one of the reservoir sites that enables the HIV virus to persist in the body even after years of treatment. In order to attack this reservoir and eventually find a cure, it is vital to learn if certain medications can suppress HIV in the CNS.

Detailed Description:

HIV infection is controllable with antiretroviral therapy (ART), but ART cannot eliminate HIV reservoirs. Thus, there is no available cure for HIV. There is a large and growing body of evidence that the central nervous system (CNS) is an HIV reservoir site and a barrier to HIV eradication. HIV DNA is commonly found in brain from people with HIV (PWH) on suppressive ART. HIV genetic compartmentalization occurs in both the brain and CSF, showing that CNS HIV is distinct from peripheral sources such as blood. Multiple studies have demonstrated that CSF HIV RNA can be detected at very low levels during suppressive ART. A study from the AIDS Clinical Trials Group (ACTG) found HIV DNA in CSF cells from approximately 50% of PWH on suppressive ART, a finding that was associated with neurocognitive impairment. The study team's group recently demonstrated a significant advance in quantitating HIV from the CSF. Specifically, CSF cell associated HIV RNA was quantifiable in 90% and CSF HIV DNA was quantifiable in 80% of PWH on suppressive ART. Based on these multiple lines of evidence that the CNS is an HIV reservoir, more research is needed on therapies that have the potential to target the CNS reservoir.

The study team has performed extensive pre-clinical and clinical work on the Janus Kinase (Jak 1/2) inhibitor drug class for viral infections. This includes work on ruxolitinib and baricitinib, two FDA approved orally bioavailable agents for myelofibrosis and polycythemia vera (ruxolitinib) as well as rheumatoid arthritis (baricitinib). The investigators have evaluated their potential to target HIV in the CNS in vitro, ex vivo, and in vivo Specifically, the study team has demonstrated that these agents block HIV replication and infection in key CNS cells, reduce the lifespan of HIV CNS reservoirs, and block reservoir reseeding. In vivo, the study team has shown in the murine model that baricitinib decreases CNS HIV and reverses behavioral abnormalities associated with HIV, which correlates with reversal of phenotypic markers of brain inflammation. This has also demonstrated that baricitinib reaches therapeutic CNS concentrations in the rhesus macaque model (including in brain parenchyma) as well as in humans. In a recently published multi-site Phase 2a ACTG-sponsored study with ruxolitinib (A5336, n = 60),the research group demonstrated that ruxolitinib is safe, well-tolerated, and reduces key markers of immune activation. New data that ruxolitinib decreased the peripheral HIV reservoir in a subset of A5336 participants provides even more evidence for this drug class to be included in eradication strategies. However, A5336 did not have any CNS assessments. The investigators now propose to study baricitinib, one of the most promising Jak 1/2 inhibitors with once daily dosing, renal clearance, and a more favorable safety/ pharmacokinetic profile, as a therapy to decrease the HIV CNS reservoir in PWH with durable virologic suppression on ART.

12. Changes in Stroop Test (Color Naming and Color-Word) [ Time Frame: Baseline and study week 10 ]

    In psychology, the Stroop effect is the delay in reaction time between congruent and incongruent stimuli.

    The effect has been used to create a psychological test (the Stroop test) that is widely used in clinical practice and investigation.

    A basic task that demonstrates this effect occurs when there is a mismatch between the name of a color (e.g., "blue", "green", or "red") and the color it is printed on (i.e., the word "red" printed in blue ink instead of red ink). When asked to name the color of the word it takes longer and is more prone to errors when the color of the ink does not match the name of the color.

    Word, color, and color-word T-Scores of 40 or less are considered "low." Word, color, and color-word T-Scores above 40 or are considered "normal." In order for one score to be considered "higher" or "lower" than another, a 10 point or greater T score difference is required.

13. Changes in Hopkins Verbal Learning Test II (Learning and Recall) [ Time Frame: Baseline and study week 10 ]

    This will be performed in a quiet exam room. Participants will have the opportunity to take breaks as needed and snacks will be provided.

    The Hopkins Verbal Learning Test-Revised (HVLT-R) is used to assess acquisition and delayed recall. The HVLT-R is a list learning test, which consists of 12 nouns within three semantic groups. The acquisition variable consists of three acquisition trials in which the administrator reads the words aloud and then asks the child to repeat as many as he/she can remember in any order. A delayed recall trial is introduced after 20-25 min, in which the child is asked to simply retrieve as many of the words listed in the acquisition trial as he/she can remember. The children are not informed about the delayed recall trial beforehand. Lower raw scores indicate difficulties with the task.

14. Changes in Brief Visuospatial Test (Learning and Recall) [ Time Frame: Baseline and study week 10 ]

    The Brief Visuospatial Memory Test (BVMT) is a commonly used assessment tool to measure visuospatial learning and memory abilities.

    In three Learning Trials, the respondent views the stimulus page for 10 seconds and is asked to draw as many of the figures as possible in their correct location on a page in the response booklet. A Delayed Recall Trial is administered after a 25-minute delay. Last, a Recognition Trial, in which the respondent is asked to identify which of 12 figures were included among the original geometric figures, is administered.

    An optional Copy Trial may be administered to screen for severe visuoconstructive deficits and to help in scoring recall responses.

    12 scores may be derived from BVMT-R performance. Recall performance is recorded for each of the immediate recall trials (Trial 1, Trail 2, and Trial 3) and for the delayed recall trial (Delayed Recall).

    The recall scores are combined to form three additional summary measures of learning and memory.

15. Changes in Trailmaking [ Time Frame: Baseline and study week 10 ]

    The Trail Making Test is a neuropsychological test of visual attention and task switching. It requires a subject to connect a sequence of 25 consecutive targets on a sheet of paper or computer screen. There are 2 parts to the test: in the first, the targets are all numbers from 1 to 25 and the test taker needs to connect them in sequential order; in the second part, the dots go from 1 to 13 and include letters from A to L. As in the first part, the patient must connect the dots in order while alternating letters and numbers, as in 1-A-2-B-3-C..., in the shortest time possible without lifting the pen from the paper. If the subject makes an error, the administrator corrects them before moving on to the next dot.

    The subject's goal is to finish both parts as quickly as possible, with the time taken to complete the test being used as the primary performance metric. Scoring is based on time taken to complete the test (e.g. 35 seconds yielding a score of 35) with lower scores being better

16. Changes in Digit Symbol Test [ Time Frame: Baseline and study week 10 ]

    This will be performed in a quiet exam room. Participants will have the opportunity to take breaks as needed and snacks will be provided.

    The Digit Symbol Substitution Test (DSST) is a paper-and-pencil cognitive test presented on a single sheet of paper that requires a subject to match symbols to numbers according to a key located on the top of the page. The subject copies the symbol into spaces below a row of numbers. The number of correct symbols within the allowed time, usually 90 to 120 seconds, constitutes the score.

17. Changes in Letter Number Sequencing Test [ Time Frame: Baseline and study week 10 ]

    This will be performed in a quiet exam room. Participants will have the opportunity to take breaks as needed and snacks will be provided.

    Letter-number sequencing is a subtest of the WAIS (Wechsler Adult Intelligence Scale) and the WISC (Wechsler Intelligence Scale for Children). It is a test that measures an individual's short-term memory skills in being able to process and re-sequence information. The task involves hearing a series of letters and digits, and then reporting back the stimuli with the letters in alphabetical order, and digits in ascending numerical order. The task is traditionally administered orally, but recent studies have administered versions of the tasks visually by displaying stimuli on a computer screen. Results suggest that performance differences on the Letter-Number Sequencing task may arise as a function of language background and task administration modality

18. Changes in Wisconsin Card Sorting Test [ Time Frame: Baseline and study week 10 ]
    This will be performed in a quiet exam room. Participants will have the opportunity to take breaks as needed and snacks will be provided.
19. Changes in Grooved Pegboard Test [ Time Frame: Baseline and study week 10 ]

    This will be performed in a quiet exam room. Participants will have the opportunity to take breaks as needed and snacks will be provided.

    The Grooved Pegboard Test (GPT) is used primarily as a measure of motor functioning, but some research indicates that performance on this test my also reflect cognitive factors, particularly attention and executive functioning.

    This manipulative dexterity test contains twenty-five holes with randomly positioned slots and pegs which have a key along one side. Pegs must be rotated to match the hole before they can be inserted.

    This procedure measures performance speed in a fine motor task by examining both sides of the body, inferences may be drawn regarding possible lateral brain damage.

    The test requires more complete visual motor coordination than most of our pegboards and has been used in several neuropsychological test batteries, in student labs, and as a screening technique in industrial environment.

20. Changes in Letter and category fluency test [ Time Frame: Baseline and study week 10 ]
    This will be performed in a quiet exam room. Participants will have the opportunity to take breaks as needed and snacks will be provided.
21. Changes in Beck Depression Inventory II (BDI-II) [ Time Frame: Baseline and study week 10 ]

    This will be performed in a quiet exam room. Participants will have the opportunity to take breaks as needed and snacks will be provided. The BDI-II is a widely used 21-item self-report inventory measuring the severity of depression in adolescents and adults.

    The questionnaire consists of 21 questions with answers ranging from 0 to 3. Scores are later analyzed by adding all scores and comparing to ranges :

    0-10:These ups and downs are considered normal 11-16:Mild mood disturbance 17-20:Borderline clinical depression 21-30:Moderate depression 31-40: Severe depression over 4: Extreme depression

22. Changes in MRI neuroimaging findings [ Time Frame: Baseline and study week 10 ]

    This will be performed with established techniques to evaluate brain structure and function.

    Briefly, magnetic resonance (MR) images will be acquired on a 3T Siemens Magnetom Prisma-Fit scanner with a 32-channel receiver array head coil. Blood oxygenation level dependent (BOLD) contrast rsfMRI scans will be acquired using a simultaneous multi-slice (SMS) gradient echo (GE) echo planar imaging (EPI) sequence.
