About this study
Official title: Placebo-controlled, Dose-response Study of Ibuprofen Effects on Brain Function
The aim of this project is to determine whether the acute oral administration of Ibuprofen changes the activation pattern in the amygdala and other brain structures during functional magnetic resonance imaging. The investigators use a double-blind, randomized, repeated-measures design. Each of the 20 healthy control subjects will be tested three times and receive placebo, 200 mg or 600 mg dose of ibuprofen p.o. The study will consist of 4 sessions: a baseline screening session and 3 testing sessions scheduled 1-2 weeks apart. Each of these individuals will undergo a multi-level assessment based on the RDoC approach that consists of (a) a standardized diagnostic assessment, (b) self-report questionnaires assessing the positive and negative valence domains as well as interoception, (c) behavioral tasks assessing reward-related processing, avoidance, and aversive processing, cognition, and interoception; (d) physiological measurements consisting of facial emotion expression monitoring, heart rate and respiration, (e) functional magnetic resonance imaging focusing on reward-related processing, fear conditioning and extinction, cognitive inhibition, and interoceptive processing, and (f) biomarker assessments.
Read the detailed description
Occasional OTC nonsteroidal anti-inflammatory drugs (NSAID) use is prevalent in the United States (25% aspirin, 9% ibuprofen, and 2% naproxen). An estimated 36 million Americans use over-the-counter (OTC) analgesics daily, however, considering the widespread use of analgesic agents, the overall incidence of serious drug-drug interactions involving these agents has been relatively low. Neuroinflammatory mechanisms have been implicated in depression, and NSAIDs have been found effective in animal models of depression both in monotherapy and when used to augment antidepressant drugs. However, results with NSAIDs have been mixed in human observational studies, with both better and worse depression outcomes reported. In animal studies, mice injected with BCG showed an increase in the total immobility time during the forced swim test (FST) and the tail suspension test (TST) and an increase in cerebral PGE2 and NO levels. Ibuprofen decreased the total immobility time during FST and TST and decreased cerebral PGE2 and NO levels, which was comparable to fluoxetine's effect. This would suggest that ibuprofen might have an antidepressant effect through inhibition of PGE2 and NO production.
Some studies have demonstrated the success of augmentation of antidepressant therapy with nonsteroidal anti-inflammatory drugs (NSAID) in decreasing depressive symptoms. However, little is known about the benefit of NSAID therapy on depressive symptoms. In a recent meta-analysis, using multivariable regression analysis a detectable effect in lowering PHQ-9 score in the ibuprofen or naproxen group (-0.31) and Celebrex group (-0.61) (p= .0390) was observed. However, in a study with cognitively normal volunteers age 70 and older with a family history of Alzheimer-like dementia who were randomly assigned to receive celecoxib 200 mg twice daily, naproxen sodium 220 mg twice daily, or placebo the investigators found no treatment effect on geriatric depression scores over time in the subgroup of participants with significant depressive symptoms at baseline. Moreover, there is some concern that anti-inflammatory drugs inhibit the antidepressant effects of SSRIs. In the only published fMRI study, ten healthy subjects underwent a double-blind, placebo-controlled, randomized, cross-over phFMRI study with somatosensory painful stimulation of the right median nerve. These authors reported a task-related increase of BOLD signal between drug and placebo in the primary somatosensory area and the middle frontal gyrus that was not related to changes in subjective pain scores. Thus there is some evidence that ibuprofen influences the BOLD response in specific pain-related brain areas. Taken together, there is mixed evidence for the effect of ibuprofen on mood and no data on its effect on the emotion circuitry.
Hypotheses:
- The activation pattern in the amygdala during risk-taking decision-making will be attenuated by ibuprofen in a dose dependent manner.
- The activation pattern in the amygdala during anticipatory emotional arousal will be attenuated by ibuprofen in a dose dependent manner.
- The activation pattern in the amygdala during emotional face processing will be attenuated by ibuprofen in a dose dependent manner.
- The behavioral response during tasks assessing emotional and cognitive processes including positive and negative valence and reward based learning will be modulated by ibuprofen in a dose dependent manner.

Questions about this trial
What is this clinical trial studying?
A Phase 2/3 study testing Ibuprofen in people with Major Depressive Disorder, run by Laureate Institute for Brain Research, Inc. at 1 site in United States.
The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
The sponsor lists 3 inclusion and 13 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: finished, as of the sponsor's last update on 23 Feb 2018. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 1 site in United States. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. Some participants in this study may receive a placebo. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
What does this combined phase mean?
Phase 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.
Phase 3 studies compare the treatment with the current standard treatment or a placebo in a large group, to confirm how well it works and watch for side effects.
Not every study follows the same path, and some studies (observational studies, device studies) have no phase.
Are results available for this study?
Yes. Results are posted in the registry (first posted 23 Feb 2018). A summary is in the For doctors view, and the full results are on ClinicalTrials.gov.
How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Dose-dependent Differences in the BOLD Response to fMRI Tasks in the Amygdala (time frame: 3-6 weeks). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
On the ClinicalTrials.gov record for NCT02507219, which also lists 9 linked publications.
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 23 Feb 2018.
