Abstract

The main purpose of this study is to examine the effects of infliximab on measures related to depression symptoms. Infliximab is also known by its brand name Remicade. Infliximab, or Remicade, is given to by an intravenous (IV) needle and is currently used to treat rheumatoid arthritis and Crohn's disease. Infliximab is thought to help these conditions because it reduces inflammation in the body. Infliximab (Remicade) reduces inflammation by blocking a chemical in the body called tumor necrosis factor (TNF)-alpha. This chemical produces inflammation. Inflammatory chemicals in the body like TNF-alpha appear to be increased in some people with major depression. Researchers believe that a drug like infliximab, which blocks TNF-alpha, may be helpful in treating depression.
This is a double-blind, placebo-controlled study in which participants will be randomized to receive one infusion of infliximab or placebo. The study will assess neuroimaging measures of corticostriatal circuitry before and after a placebo-controlled pharmacologic blockade of inflammation in 80 depressed patients.

The main purpose of this study is to examine the effects of infliximab on measures related to depression symptoms. Infliximab is also known by its brand name Remicade. Infliximab, or Remicade, is given by an intravenous (IV) needle and is currently used to treat rheumatoid arthritis and Crohn's disease. Infliximab is thought to help these conditions because it reduces inflammation in the body. Infliximab (Remicade) reduces inflammation by blocking a chemical in the body called tumor necrosis factor (TNF)-alpha. This chemical produces inflammation. Inflammatory chemicals in the body like TNF-alpha appear to be increased in some people with major depression. Researchers believe that a drug like infliximab, which blocks TNF-alpha, may be helpful in treating depression.

This is a double-blind, placebo-controlled study in which participants will be randomized to receive one infusion of infliximab or placebo. This study will assess neuroimaging measures of corticostriatal circuitry before and after a placebo-controlled pharmacologic blockade of inflammation in 80 depressed patients (n = 40 per group) recruited to ensure high levels of peripheral inflammation (CRP > 3mg/L).

Primary aims are to evaluate whether 1) corticostriatal function during reward motivation and anticipation are associated with change in peripheral inflammation following pharmacologic blockade relative to placebo 2) the temporal dynamics of change in inflammation, gene- expression, reward motivation and reinforcement learning behavior and motivational symptoms assessed at baseline, and 24 hours, 3 days, 1 week and two weeks post infliximab infusion, and 3) test an integrative multi- level path model to determine whether change in corticostriatal circuitry following inflammation blockade mediates the relationship between change in inflammation and change in motivational anhedonia symptoms.

These data will provide further validation of inflammatory cytokines as therapeutic targets for motivational symptoms in depression and will define symptom targets and biomarkers of response for future studies.

Outcome

Primary Outcome Measures

1. Change in Reward Motivation assessed by the Behavioral Effort-Expenditure for Rewards Task (behEEfRT) Score [Baseline, Day 14]

Assessment of reward motivation will be accomplished using an fMRI-adapted version of the EEfRT task.The behEEfRT task is a multi-trial game in which participants are given an opportunity on each trial to choose between two different task difficulty levels in order to obtain monetary rewards. The higher the reward, the more motivation the participant expresses.

Secondary Outcome Measures

1. Change in the Columbia Suicide Severity Rating Scale (C-SSR) Score [Baseline, Day 14]

The C-SSR is a suicidal ideation rating scale created to evaluate suicidality in children ages 12 and up. It rates an individual's degree of suicidal ideation on a scale, ranging from "wish to be dead" to "active suicidal ideation with specific plan and intent." The scale identifies behaviors which may be indicative of an individual's intent to commit suicide. An individual exhibiting even a single behavior identified by the scale was 8 to 10 times more likely to commit suicide.

2. Change in the Multidimensional Fatigue Inventory (MFI) Score [Baseline, Day 14]

The MFI is a 20-item self-report instrument designed to measure fatigue, covering the dimensions General Fatigue (GF), Physical Fatigue (PF), Mental Fatigue (MF), Reduced Motivation (RM) and Reduced Activity (RA). A higher total score indicates more fatigue.

3. Change in Inventory of Depressive Symptoms Self-Report (IDS-SR) Score [Baseline, Day 14]

The IDS-SR is a 30 item measure designed to assess the severity of depressive symptoms. A higher score indicates more depressive symptoms.

4. Change in the Positive Affect/Negative Affect Scale - Now (PANAS-X) Score [Baseline, Day 14]

The PANAS-X measures four basic negative emotions (fear, hostility, guilt, and sadness), three basic positive emotions (joviality, self-assurance, and attentiveness), and four more complex affective states (shyness, fatigue, serenity, and surprise).The PANAS scale gives a score for positive and negative affect between 10 and 50 points. A higher score expresses more affect.

5. Change in the Snaith-Hamilton Pleasure Scale (SHAPS) Score [Baseline, Day 14]

The Snaith-Hamilton Pleasure Scale (SHAPS) is a self-administered, paper-pencil questionnaire with 14 items assessing four domains of pleasure response/hedonic experience: interest/pastimes, social interaction, sensory experience, and food/drink. The SHAPS is scored as the sum of the 14 items so that total scores ranged from 0 to 14. A higher total SHAPS score indicated higher levels of anhedonia. A cut-off score of 2 provides the best discrimination between "normal" and "abnormal" level of hedonic tone.

6. Change in the Fatigue Severity Scale (FSS) Score [Baseline, Day 14]

The FSS questionnaire contains nine statements that rate the severity of fatigue symptoms. A total score of less than 36 suggests that a participant may not be suffering from fatigue. A total score of 36 or more suggests that a participant may need further evaluation by a physician.

7. Change in the Mood and Pleasure Scale (MAP-SR) Score [Baseline, Day 14]

The MAP-SR is an 18-item self-report measure related to social and recreational or work domains, feelings and motivations to be around family, romantic partners, and friends, and effort to engage in activities. All items are rated on a 5-point Likert scale; higher scores reflect greater pathology.

8. Change in the Go No-Go Variant Task Score [Baseline, Day 14]

During the Go No-Go variant task stimuli are presented in a continuous stream and participants perform a binary decision on each stimulus. One of the outcomes requires participants to make a motor response (go), whereas the other requires participants to withhold a response (no-go). Accuracy and reaction time are measured for each event.

9. Change in Finger Tapping Task (FTT) Score [Baseline, Day 14]

The FTT uses a specially adapted tapper that the subject taps as fast as possible using the index finger. The subject is given 5 consecutive 10-second trials for the preferred and non-preferred hands. The finger tapping score is the mean of 5 trials and is computed for each hand.

10. Change in Reaction Time Task (RTT) Score [Baseline, Day 14]

The RTT provides measures of simple and choice movement and reaction time tasks and is divided into 5 stages requiring increasingly complex chains of responses and providing distinction between reaction (or decision) time and movement latencies. The test measures assessing correct and incorrect responses, errors of commission and omission (late and early responses), and latency (response speed).

11. Change in Digit Symbol Task (DST) Score. [Baseline, Day 14]

The DST consists of rows of blank squares, each printed with a randomly assigned number. The test involves graphimotor speed, visual scanning and memory, with about half of the variance being accounted for by graphimotor speed, a third by visual scanning and 4-5% by memory. The number of correct symbols within the allowed time is measured.

12. Change in Plasma C-reactive Protein (CRP) Level [Baseline, Day 14]

C-reactive protein (CRP) is a blood test marker for inflammation in the body. CRP is produced in the liver and its level is measured by testing the blood. Change is defined as the difference in CRP level from baseline to Day 14.

13. Change in Plasma Tumor Necrosis Factor (TNF) Alpha Level [Baseline, Day 14]

Plasma TNF-alpha level will be collected via blood draw. Change is defined as the difference in TNF-alpha level from baseline to Day 14.

14. Change in Plasma Soluble Tumor Necrosis Factor (TNF) Receptor 1 Level [Baseline, Day 14]

Plasma TNF Receptor 1 level will be collected via blood draw. Change is defined as the difference in TNF Receptor 1 level from baseline to Day 14.

15. Change in Plasma Soluble Tumor Necrosis Factor (TNF) Receptor 2 Level [Baseline, Day 14]

Plasma TNF Receptor 2 level will be collected via blood draw. Change is defined as the difference in TNF Receptor 2 level from baseline to Day 14.

16. Change in Plasma Interleukin-1 (IL-1) Level [Baseline, Day 14]

Plasma IL-1 level will be collected via blood draw. Change is defined as the difference in IL-1 level from baseline to Day 14.

17. Change in Plasma Interleukin-1 (IL-1) Receptor Agonist Level [Baseline, Day 14]

Plasma IL-1 Receptor agonist level will be collected via blood draw. Change is defined as the difference in IL-1 receptor agonist level from baseline to Day 14.

18. Change in Plasma Interleukin-6 (IL-6) Level [Baseline, Day 14]

Plasma IL-6 level will be collected via blood draw. Change is defined as the difference in IL-6 level from baseline to Day 14.

19. Change in Plasma Soluble Interleukin-6 Receptor (sIL-6R) Level [Baseline, Day 14]

Plasma sIL-6R level will be collected via blood draw. Change is defined as the difference in sIL-6R level from baseline to Day 14.
