Clinical Trial Summary

The purpose of this 10-week, double-blind, placebo-controlled study is to determine whether inflammation impacts reward and motor neural circuitry to contribute to depressive symptoms like anhedonia and psychomotor slowing in people with Human Immunodeficiency Virus (HIV) and depression. Sixty male and female patients with HIV who have depression, anhedonia and high inflammation and are stable on effective treatment for their HIV will be randomized to receive either the anti-inflammatory drug baricitinib or a placebo for 10 weeks. Participants will complete lab tests, medical and psychiatric assessments, neurocognitive testing, functional MRI (fMRI) scans, and optional spinal taps as part of the study. The total length of participation is about 5 months.

Description:

Risk of depression is substantially higher in people with HIV (PWH) than the general population, and depression in PWH confers worse outcomes regarding treatment adherence, morbidity and mortality. Increased inflammation is one biological pathway that is linked to greater risk for depression in PWH and limits options for effective antidepressant therapy. Chronically elevated inflammation is associated with impairments within reward and motor neural circuits that contribute to symptoms of anhedonia (an inability to experience pleasure) and psychomotor slowing, which are overrepresented in PWH. The purpose of this 10-week, double-blind, placebo-controlled study is to provide mechanistic information on whether inflammation impacts corticostriatal reward and motor circuitry to contribute to anhedonia and psychomotor slowing in PWH with depression using the anti-inflammatory drug baricitinib.

This study will utilize an FDA-approved medication, baricitinib, to establish whether the effects of inflammation on reward and motor circuits are a mechanism of anhedonia and motor slowing in PWH with depression, while advancing avenues for new therapies.

Sixty male and female patients with HIV who have depression and high inflammation and are stable on effective treatment for their HIV will be randomized to receive either baricitinib or a placebo for 10 weeks. Participants will complete lab tests, medical and psychiatric assessments, neurocognitive testing, functional MRI (fMRI) scans, and optional spinal taps as part of the study. The total length of participation is about 3.5 months.

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Change in corticostriatal functional connectivity (FC) in reward circuit	Patients will undergo resting-state and task-based functional magnetic resonance imaging (fMRI) to calculate functional connectivity (FC) between the ventral striatum (VS) and ventromedial prefrontal cortex (vmPFC). FC is measured as continuous Z scores reflecting the correlation of activity between the brain regions. Higher FC Z scores reflect stronger connectivity.	Baseline visit, week 2, and week 10 after study medication
Secondary	Change in Effort Expenditure for Reward Task (EEfRT) Score	The EEfRT is a widely used, multi-trial task measuring motivation for rewards as an assessment of anhedonia, as anhedonia is specifically associated with decreased motivation for rewards. For each task participants repeatedly press a button to raise a "bar" on a screen. Before each task participants choose between between receiving a "hard task" (using the non-dominant little finger) for a larger reward or an "easy task" (using the dominant index finger) for a smaller reward. The EEfRT is reported as the proportion of "hard task" trials that participants select. Possible scores range between 0 to 1 with higher scores indicating greater motivation, which in turn is an indication for lower anhedonia.	Baseline visit, week 2 and week 10
Secondary	Change in Snaith-Hamilton Pleasure Scale-Self Report (SHAPS-SR) Score	The Snaith-Hamilton Pleasure Scale (SHAPS), a 14-item self-report scale with high psychometric validity for assessing the presence of anhedonia, is used to assess hedonic capacity. Participants rate how much they agree or disagree with 14 items phrased as "I would enjoy __" based on their ability to experience pleasure. Of the four possible response categories (Definitely Agree, Agree, Disagree, and Strongly Disagree), either of the Disagree responses receives a score of 1 and either of the Agree responses receives a score of 0. The total SHAPS score is calculated as the sum of these 14 items and ranges from 0 to 14, where higher SHAPS scores indicate greater anhedonia.	Baseline visit, week 1, week 2, week 4, week 6, week 10
Secondary	Change in Motivation and Pleasure Scale-Self-Report (MAP-SR) Score	The Motivation and Pleasure-Self-Report (MAP-SR) is an 18-item self-report inventory that was created to disentangle state-wise motivational and consummatory components of everyday activities over a 24-hour period. Participants respond to statements about daily activities on a 5-point Likert scale from 0 (no pleasure/not at all) to 4 (extreme pleasure/very often). Total scores range from 0 to 72 where higher scores indicate greater motivation and effort given to everyday situations.	Baseline visit, week 1, week 2, week 4, week 6, week 10
Secondary	Change in Inventory of Depressive Symptoms Self Report (IDS-SR) Anhedonia Subscale Score	Anhedonia is assessed with a 3-item subscale of the Inventory of Depressive Symptomatology Self-Report (IDS-SR). Items are scored on a 4-point scale from 0 to 3. Total scores for the Anhedonia Subscale range from 0 to 9 with higher scores reflecting greater anhedonia.	Baseline visit, week 1, week 2, week 4, week 6, and week 10
Secondary	Change in Multidimensional Fatigue Inventory (MFI) Score	The Multidimensional Fatigue Inventory (MFI) assesses 5 dimensions of fatigue, including general fatigue, physical fatigue, mental fatigue, reduced activity and reduced motivation. Participants read 20 statements (such as "I feel very active") and indicate how true that feeling is for them on a 5-point scale where "yes, that is true" = 1 and "no, that is not true" = 5. Total scores range from 20 to 100 and higher scores indicate greater fatigue.	Baseline visit, week 1, week 2, week 4, week 6, and week 10
Secondary	Change in Finger Tapping Task (FTT) Mean Number of Taps	The Finger Tapping Task (FTT) uses a specially adapted tapper that the participant taps as fast as possible using the index finger. The participant is given 5 consecutive 10-second trials for the preferred and non-preferred hands. The FTT score is calculated as the mean number of taps for the preferred and non-preferred hands. The FTT is designed to assess subtle motor impairment and is altered in subjects with basal ganglia disorders and lesions. A lower score indicates motor impairment.	Baseline visit, week 2 and week 10
Secondary	Change in Finger Tapping Task (FTT) Total Number of Taps	The Finger Tapping Task (FTT) uses a specially adapted tapper that the participant taps as fast as possible using the index finger. The participant is given 5 consecutive 10-second trials for the preferred and non-preferred hands.; The FTT score is calculated as the total number of taps for the preferred and non-preferred hands. The FTT is designed to assess subtle motor impairment and is altered in subjects with basal ganglia disorders and lesions. A lower score indicates motor impairment.	Baseline visit, week 2 and week 10
Secondary	Change in Trail Making Test Part A (TMT-A) Score	The Trail Making Test Part A (TMT-A) measures psychomotor processing speed by asking participants to accurately draw lines connecting circles printed on a piece of paper as quickly as possible. In Part A, participants connect 25 circles in numeric sequence and the test is scored as the time in seconds that it takes to complete. Higher scores (i.e., time) indicate poorer performance.	Baseline visit, week 2 and week 10
Secondary	Change in Retardation Rating Scale (RRS) Score	The Retardation Rating Scale (RRS) is a 14-item, clinician-administered scale used to assess psychomotor retardation (a feature of depression) related to motility or mental activity. Items are scored on a scale from 0 to 4 where normal = 0 and extremely severe = 4. Total scores range from 0 to 56 where higher scores indicate increased severity of depression.	Baseline visit, week 1, week 2, week 4, week 6, and week 10
