Brief Summary:

Depression is one of the most important causes of disability in the world today, with major personal, social and economic costs. Although some moderately effective drug treatments are already available, about a third of patients with major depressive disorder (MDD) remain depressed despite current treatment.

There is growing evidence that inflammation - the response of the body's immune system to physical and social stresses - can cause depressive symptoms in some patients. It is therefore predicted that anti-inflammatory drugs could have anti-depressant effects and the research team aims to test this using a new drug, JNJ-54175446, which blocks the activity of a receptor called P2X7. P2X7 is present on many immune cells and plays a key role in the release of inflammatory molecules during stress, which may be linked to stress-related depression.

The research team will recruit approximately up to 142 participants with MDD to this clinical trial. Patients will have moderate-severe depressive symptoms despite ongoing treatment with a conventional anti-depressant drug, and they will have blood test results at screening that indicate they are likely to have active P2X7 signalling in the brain. Eligible participants will be randomly allocated to receive either 50mg/day JNJ-54175446 or placebo for 8 weeks. Participants will be assessed at weeks 2, 5 and 8 using a standard clinical depression scale and the scores compared between those treated with placebo and those treated with JNJ-54175446. To understand more about the effects of JNJ-54175446 on the immune system and the brain, patients will also complete additional blood tests, questionnaires and magnetic resonance imaging (MRI) brain scans at different visits throughout the trial. The trial will be carried out across 5 centres in the UK.

  Hide Detailed Description

Detailed Description:

This trial will be a multi-centre, phase II, randomised, double blinded, placebo-controlled, parallel group trial.

The research team estimates that the majority of the participants will be recruited through the trial website, posters and research databases. In order to better assess the suitability of the interested participants, interested participants are required to answer pre-screening questions.

Only those who might be suitable to take part will be invited to a screening visit to continue with the rest of the trial screening procedures. The trial will consist of 3 phases - a screening phase, treatment phase of 8 weeks and follow up phase. This includes a total of 6 clinic visits and will be spread over about 15 weeks. Each clinic visit will last between 1.5 hours to 5 hours. Participants will have to be fasted overnight (10 hrs) prior to baseline visit 1 and visit 4 for biomarker blood samples. At these visits, breakfast will be provided after sample collection.

The list below outlines the study schedule and key assessments applicable to a participant who passes the pre-screening questions:

Screening phase clinic visit Participants who are interested in taking part will be invited to attend a screening visit in the clinic which lasts about 4 hours. At this visit the trial team will discuss the trial further and answer any queries the participants may have. If the participants agree, they will then provide informed consent prior to any screening tests and procedures being undertaken. An alcohol breath test and urine drug screen will be carried out. Urine samples will be taken for urinalysis.

Blood samples will be taken for safety assessments including full blood count, clinical chemistry tests, thyroid function tests, pregnancy and Follicle-stimulating hormone test (if applicable). Biomarker blood samples will also be taken for genetic analysis of P2X7 receptor and analysis of C-reactive protein (CRP) for eligibility check, and for other biomarker assays including genetic analysis. Other screening assessments include a review of the participant's medical and medication history, review of their depressive disorder and self-reported stress, and a physical examination. Vital signs will be measured and participants will have an electrocardiogram (ECG) performed. Participants will also be introduced to the other trial activities that will have to be carried out in their homes. This includes collection of saliva samples, the use of activity monitoring device and completion of daily sleep diary.

Screening phone call Once results from the genetic analysis of the P2X7 receptor and CRP levels are available (about 1 to 2 weeks after the screening visit), the results will be returned to the site team who will then inform the participant by phone whether they are eligible. If eligible, a baseline clinic visit will be arranged.

During this call, eligible participants will be reminded that saliva sample collection packs will be sent in the post, to collect saliva samples at specific time points and return them to the research team. Participants will also be sent an activity monitoring watch and sleep diary; participants should start wearing the watch everyday for at least 7 days prior to baseline visit and record their sleep.

Baseline/Treatment phase Visit 1 Participants will be asked to fast a minimum of 10 hours and attend a baseline site visit (Day 1) which would last approximately 5 hours.

At this visit, the participant's diagnosis of major depressive episode will be re-checked to ensure they are still eligible. Fasting blood samples will be taken for full blood count, clinical chemistry, biomarkers and baseline drug concentration analysis. After breakfast is given, an alcohol breath test and urine drug screen will be carried out. Urine samples will be taken for urinalysis and pregnancy test (if applicable). An ECG will be performed and vital signs will be assessed. Participants who continue to meet eligibility will be randomised in 1:1 ratio to receive JNJ-54175446 or placebo.

Participants will be asked about any adverse events and concomitant therapies. Various clinical and participant reported questionnaires will be completed to assess stress, depression symptoms and suicidal risk. Participants will be asked to complete a range of online cognition tests, during which heart rate variability measurements will be carried out. Participants will also have a baseline MRI scan which includes completion of a cognitive task during the scan. At the end of the visit, participants will receive 1 bottle of allocated trial drug and will be instructed to take 1 capsule every day within 30 minutes after breakfast. A medication diary will be provided to aid participants in recording their daily administration. Data from the activity watch will be downloaded and a new copy of daily sleep diary will be provided.

Visit 2 and Visit 3 Participants will be required to attend a visit to the site at Day 14 ± 2 (Visit 2) and at Day 32 ± 3 (Visit 3), each visit will last approximately 3 ½ hours. Participants do not need to be fasted for these visits. On these days, participants should not take their trial drug at home, they will be asked to take the drug at clinic after their blood and urine collection. At this visit, blood samples will be taken for full blood count, clinical chemistry analysis, CRP and drug concentration analysis. A urine drug screen will be carried out. Urine samples will be taken for urinalysis and pregnancy test (if applicable). Participants will then be asked to take their drug. An ECG will be performed and vital signs will be assessed. Participants will be asked about any adverse events and concomitant therapies. Various clinical questionnaires will be carried out to assess stress, depression and suicidal risk. Participants will be asked to complete a range of online cognition tests. Participant's trial drug compliance will be reviewed through review of the medication diary (visits 2 and 3) and physical counting of returned capsules (visit 3). Data will be downloaded from the activity monitoring device at each of these visits and a new daily sleep diary will be provided. At visit 3, participants will receive the 2nd bottle of allocated trial drug.

Telephone checks In order to maintain regular contact with the participants, the research team will contact the participants by telephone 8 to 12 days after visit 2 (phone check #1) and 8 to 12 days after visit 3 (phone check #2). Participants will be asked if they have had any adverse events, any changes to concomitant therapies and if they had been able to take the trial drug according to trial instructions.

At phone check #2, participants will also be instructed to collect saliva samples within 7 days before the next visit. The saliva collection packs will be posted to the participants.

Visit 4 Participants will attend a clinic visit on Day 56 ± 3 (Visit 4) lasting approximately 5 hours. Participants need to come to the site in fasted condition (minimum of 10 hours) and should not take their trial rug at home, they will be asked to take the drug at clinic after blood and urine collection and breakfast. This will be the final dose for the participants. At this visit, fasting blood samples will be taken for full blood count, clinical chemistry analysis, CRP and biomarkers and drug concentration analysis. A urine drug screen will be carried out. Urine samples will be taken for urinalysis and pregnancy test (if applicable). Participant will then be asked to take their drug. An ECG will be performed and vital signs will be assessed. Targeted physical examination will be carried out. Participants will be asked about any adverse events and concomitant therapies. Various clinical and participant reported questionnaires will be completed to assess stress, depression symptoms and suicidal risk. Participants will be asked to complete a range of online cognition tests, during which heart rate variability measurements will be carried out. The anti-depressant response will be assessed using a clinical scale (MADRS). Participants will also have a post-treatment MRI scan which includes completion of a cognitive task during the scan. Data will be downloaded from the activity monitoring device and the device collected from the participants. All unused drug will be collected from the participants.

Follow up visit (Visit 5) A follow-up visit will be scheduled between 7 and 14 days after last dose of administration (visit 4) and will last approximately 1 hour. Blood samples will be taken for full blood count, clinical chemistry and CRP analysis. Urine samples will be taken for urinalysis and pregnancy test (if applicable). An ECG will be performed and vital signs will be assessed. Participants will be asked about any adverse events and concomitant therapies. Targeted physical examination and medical review of symptoms and systems will be carried out and body weight measured. Participants will be asked to complete a depression questionnaire.

Home-based trial assessments Participants will be requested to wear the activity monitoring device from 7 days prior to visit 1 (Day -7) up until visit 4, and complete a daily sleep diary. This activity monitoring device will record the participant's activity and sleep patterns.

Participants have to self-administer 1 capsule of trial drug daily, preferably in the morning and within 30 min after breakfast. The date and time of administration should be recorded in the medication diary.

Participants will have to provide 2 sets of 6 saliva samples each during the trial.

Data analysis The primary endpoint is the change between baseline score and score at final dose on visit 4 (week 8) assessed by the MADRS scale. 142 participants will be enrolled. All data will be analysed and summarised in a clinical trial report.

Secondary Outcome Measures :
  1. Change from baseline in total score on the MADRS scale [ Time Frame: At baseline, 2 and 5 weeks of treatment ]
    The Montgomery Asberg Depression Rating Scale (MADRS), a researcher-rated scale designed to measure depression severity and detects changes due to antidepressant treatment. The test consists of 10 items, each of which is scored from 0 (item not present or normal) to 6 (severe or continuous presence of the symptoms), for a total possible score of 60. Higher scores represent a more severe condition.

  2. Change in scores on Perceived Stress Scale [ Time Frame: At baseline, 2, 5 and 8 weeks of treatment ]
    Perceived Stress Scale is a questionnaire measure of recent or current social stress. This scale ranges from 0 to 40; scores ranging from 0-13 would be considered low stress; scores ranging from 14-26 would be considered moderate stress; scores ranging from 27-40 would be considered high perceived stress.

  3. Change in scores on SHAPS [ Time Frame: At baseline, 2, 5 and 8 weeks of treatment ]
    Snaith-Hamilton Pleasure Scale. SHAPS is an instrument developed for the assessment of hedonic capacity and consists of 14-items. Four major domains are covered in the scale, namely interest/pastimes, social interaction, sensory experience, and food/drink. The score range is 0-14. The higher the score the lower the ability to experience pleasure of the patient.

  4. Change in scores on CFQ [ Time Frame: At baseline, 2, 5 and 8 weeks of treatment ]
    Chalder Fatigue Questionnaire (CFQ). The Fatigue Scale, sometimes referred to as the Chalder Fatigue Questionnaire, is a self-administered questionnaire for measuring the extent and severity of fatigue within both clinical and non-clinical, epidemiological populations. The respondent's global score can range from 0 to 33. The global score also spans two dimensions—physical fatigue (measured by items 1-7) and psychological fatigue (measured by items 8-11).

  5. Change in scores on QIDS-SR16 [ Time Frame: At baseline, 2, 5 and 8 weeks of treatment ]
    Quick Inventory of Depressive Symptomatology (QIDS-SR16). The QIDS-SR16 is designed to assess the severity of depressive symptoms and is sensitive to change due to with medications, psychotherapy, or other treatments. Participants will provide responses to each item of this instrument with a 4-point Likert scale, with scores ranging from 0-3 for each item. The total score ranges from 0 to 27. Using a scale of severity of depression of none, mild, moderate, severe, and very severe, corresponding QIDS-SR16 total scores are none 1 to 5, mild 6 to 10, moderate 11 to 15, severe 16 to 20 and very severe 21 to 27.

  6. Change in scores on GAD-7 [ Time Frame: At baseline, 2, 5 and 8 weeks of treatment ]
    Generalized Anxiety Disorder 7 (GAD-7). GAD-7 is a self-reported questionnaire for screening and severity measuring of GAD. GAD-7 has seven items, which measure severity of various signs of GAD according to reported response categories with assigned points. Assessment is indicated by the total score, which made up by adding together the scores for all 7 items. The score ranges from 0 to 21. Using a scale of severity of anxiety of none, mild, moderate and severe, corresponding to GAD-7 total scores are none 0 to 4, mild 5 to 9, moderate 10 to 14 and severe 15 to 21.

  7. Change in score on participant self-reported depression scale [ Time Frame: At baseline and at 8 weeks of treatment ]
    Participants will be asked to self-assess their depression using the Beck Depression Inventory scale (BDI). BDI is a 21-question multiple-choice self-report inventory, widely used for assessment of depression, including in the NIMA BIODEP study, with a score range of 0-63. Each of the 21 items is rated by the participant on a 4 point scale.

  8. Change in scores in the cognitive function test ReVeRe-D [ Time Frame: At baseline, 2, 5 and 8 weeks of treatment ]
    Revere-D is an application developed by Johnson and Johnson, and consists of a battery of eight validated cognitive tasks that assesses cognitive functions, such as memory and learning, that do not involve cognitive processing of emotionally salient stimuli.

  9. Change in scores in Continuous performance test [ Time Frame: At baseline, 2, 5 and 8 weeks of treatment ]
    The continuous performance test is a computerised test of sustained attention which provides a measure of cognitive fatigue.

  10. Change in scores in Emotional Test battery [ Time Frame: At baseline and 2 weeks of treatment ]
