Clinical Trial Summary

The primary objective of this research project is to compare neuropsychiatric functioning, cortical activity, white matter integrity, and immune response among Veterans with and without alcohol use disorder (AUD), before and after direct-acting antiviral (DAA) therapy [a new treatment for chronic infection with the hepatitis C virus (HCV)]. Demographically-matched comparison groups of Veterans without HCV (HCV-, with and without AUD) will similarly be evaluated to determine the relative contribution of HCV and an HCV "cure" to outcomes putatively affected by alcohol abuse.

Two specific aims are proposed.

Aim 1: Determine the impact of DAA therapy and a sustained viral response on central nervous system (CNS) function.

Aim 2: Evaluate the effects of AUD and unhealthy alcohol drinking on DAA therapy outcomes and CNS function.

The information learned will address a critical gap in knowledge concerning the effects of alcohol use on DAA therapy outcomes and will help inform treatment guidelines that could be translated to clinical practice, such as targeted interventions to treat AUD in conjunction with HCV infection and follow-up strategies for patients who successfully complete DAA therapy but then need care for other potential CNS-related outcomes.

Description:

Aim 1 will evaluate the impact of DAA therapy on CNS function in Veterans with HCV and will test the hypotheses that following DAA therapy and obtaining a sustained viral response [SVR; i.e., when the virus continues to be undetectable in blood 12 weeks (or more) after completing therapy], participants will show: i) improved neuropsychiatric outcomes (e.g., cognitive function, fatigue, mood), as compared to baseline (pre-DAA therapy), ii) restored functional connectivity and disintegrity within white matter tracks that had been observed at baseline, and iii) reduced immune activation profiles (e.g., decreased expression of inflammatory biomarkers and restored T cell balance), as compared to baseline. Aim 2 will determine the impact of an active AUD on the neuropsychiatric, neuroimaging, and immunological outcomes observed in aim 1. Participants will be evaluated at two time points [i.e., baseline and 12 weeks post-therapy (week 24)]. Evaluations will incorporate brain imaging methods [i.e., resting state magnetic resonance imaging (MRI), functional MRI, and diffusion tensor imaging] along with clinical and laboratory methods to assess the interactive effects of alcohol use and HCV on brain function. Clinical and laboratory data will include: i) demographic and medical information, ii) neuropsychological measures of attention, memory, and executive function, iii) neuropsychiatric symptom questionnaires (e.g., depression and anxiety), iv) urine and oral fluid collection for medical laboratory tests, and v) blood sample collection for planned experiments (e.g., flow cytometry, qPCR, and multiplex immunoassays) and for contribution to the VA Liver Disease Repository.

Evidence-based guidelines for the new DAA therapies are needed (e.g., How much alcohol is too much?). The VA is at the forefront of treating HCV and is now offering DAA therapy to all Veterans with HCV treated within VA health care systems. The proposed studies will address a critical gap in our knowledge concerning the effects of co-morbid HCV and AUD on antiviral therapy outcomes, particularly CNS function and neuropsychiatric symptoms that contribute to addiction and relapse.

Intervention

Diagnostic Test:
• Neuropsychological assessment
Clinical research staff will complete a standardized neuropsychiatric study visit protocol with eligible participants who provide informed consent. The protocol will be conducted twice for each participant (baseline and 6 months later).

Behavioral:
• Neuroimaging
Subjects, well characterized with respect to their substance use, will be evaluated with fMRI tasks, rsMRI, high resolution anatomical MRI, standard DWI and high angular resolution diffusion imaging (HARDI) at baseline and 6 months later.

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Changes in Neuropsychological Assessment Battery (NAB) Attention Module Scores	The neuropsychological test battery measures an individual's attentional capacity, working memory, psychomotor speed, selective attention, divided attention, and information processing speed. Raw scores will be calculated per domain and as a composite score. Differences in mean changes in composite score between baseline and end of study will be assessed with a paired T-test.	Baseline and 6 months
Primary	Changes in Neuropsychological Assessment Battery (NAB) Memory Module Scores	The neuropsychological test assesses an individual's verbal explicit learning, visual explicit learning, verbal delayed free recall, visual delayed recognition memory, and verbal explicit learning and recognition of information likely to be encountered in daily living. Raw scores will be calculated per domain and as a composite score. Differences in mean changes in composite score between baseline and end of study will be assessed with a paired T-test.	Baseline and 6 months
Primary	Changes in Neuropsychological Assessment Battery (NAB) Executive Functions Module Scores	The neuropsychological test assesses executive function, such as problem-solving, planning, and mental flexibility. Raw scores will be calculated per domain and as a composite score. Differences in mean changes in composite score between baseline and end of study will be assessed with a paired T-test.	Baseline and 6 months
Primary	Changes in alcohol use measured using the Timeline Follow Back (TLFB)	The TLFB will be used to measure change across several dimensions of alcohol drinking behavior: (a) variability (i.e., scatter); (b) pattern (i.e., shape); and (c) extent of drinking (i.e., elevation/reduction; how much).	Baseline and 6 months
Primary	Change in behavior as assessed by the Balloon Analogue Risk Task (BART)	The BART is a computerized measure of risk-taking behavior that concurrently measures several domains (i.e., risky decision-making, reward/negative outcome processing) during fMRI scanning.	Baseline and 6 months
Primary	Change in behavior as assessed by the Monetary Incentive Delay (MID) task	The MID is a validated task to examine anticipatory brain responses to reward during fMRI scanning.	Baseline and 6 months
Primary	Change in Fatigue Severity Scale (FSS) score	The Fatigue Severity Scale (FSS) is a 9-item self-report questionnaire designed to measure level of fatigue. The FSS is graded on a 7-point Likert-like scale ranging from 1 ("strongly disagree") to 7 ("strongly agree"). The minimum score is 9 and the maximum score possible is 63. A higher score represents a greater fatigue severity. The average score for all 9 items constitute the FSS score.	Baseline and 6 months
Primary	Change in Beck Depression Inventory Second Edition (BDI-II) score	The Beck Depression Inventory Second Edition (BDI-II) is a 21-question multiple-choice self-report inventory that measures depression. There is a four-point scale for each item ranging from 0-3. The total score can range from 0 to 63 points. Higher scores reflect a great level of depression severity.	Baseline and 6 months
Primary	Change in fractional anisotropy (FA) in white matter tracts	MRI-based diffusion tensor imaging (DTI) tractography is used to measure fractional anisotropy (an indicator of CNS microstructural integrity).	Baseline and 6 months
Primary	Change in mean diffusivity in white matter tracks	MRI-based DTI tractography is used to measured mean diffusivity (an indicator of CNS microstructural integrity).	Baseline and 6 months
Primary	Changes in inflammatory profile marker concentration	Immune factors in the inflammatory profile include: C-reactive protein (CRP), C-X-C motif chemokine (CXCL10), interleukin-1 beta (IL-1 beta), interleukin-6 (IL-6), interleukin-8 (IL-8), interleukin-10 (IL-10), interleukin-18 (IL-18), monocyte chemoattractant protein-1 (MCP-1), matrix metalloproteinase-3 (MMP-3), S100 calcium binding protein B (S100B), tissue inhibitor of metalloproteinase-1 (TIMP-1), and tumor necrosis factor alpha (TNF-alpha).	Baseline and 6 months
Primary	Changes in T cell subpopulation frequency	T-cells will be evaluated for changes in the frequencies of double negative (DN; CD4-CD8-) and double positive (DP; CD4+CD8+) CD3+ cells.	Baseline and 6 months
