Study of Neural Responses Induced by Antidepressant Effects (SONRISA)
October 11, 2022 updated by: Marta Peciña, MD PhD
Study of Neural Responses Induced by Simulated Antidepressants
The proposed work aims to examine the neural changes associated with fast-acting antidepressant treatments in order to develop imaging-based biomarkers of treatment response for depression.

Detailed Description
Over the past decade, neuroimaging tools have rapidly advanced the field of neural biomarkers of treatment response in depression.
Still, despite obvious scientific progress in this field, the ability to implement neuroimaging biomarkers of antidepressant treatment response in clinical trial settings is lacking.
In order to objectively assess the neural bases of treatment response in depression, the investigators will use a "Real-time Neurofeedback fMRI task", specifically designed to record and modulate mood improvement by providing neurofeedback in the context of the administration of an antidepressant treatment.
In a pilot study, positive neurofeedback during the administration of the drug was associated with significant acute mood improvement and increased blood oxygen level dependent (BOLD) responses in the rostral anterior cingulate cortex (rACC), a common neural target of antidepressant treatments.
The central hypothesis is that antidepressant effects in depression are mediated by increased neural activity in the rACC (AIM1), which can be used in clinical trials of antidepressant treatment to predict antidepressant effects (AIM 2) and assess the effect of antidepressant treatment on antidepressant-induced rACC neural responses (AIM 3).
The results obtained from this project are expected to have an important impact on our ability to understand the cognitive and neural mechanisms implicated in antidepressant treatment responses in patients with depression, as well as on the ability to implement neuroimaging biomarkers of treatment response in the clinical trial settings.

Change in Montgomery-Åsberg Depression Rating Scale (MADRS) Scores
Time Frame: baseline and week 8
|
The Montgomery-Åsberg Depression Rating Scale (MADRS) is a ten-item diagnostic questionnaire which psychiatrists use to measure the severity of depressive episodes in patients with mood disorders.
It was designed in 1979 by British and Swedish researchers as an adjunct to the Hamilton Rating Scale for Depression (HAMD) which would be more sensitive to the changes brought on by antidepressants and other forms of treatment than the Hamilton Scale was.[2] There is, however, a high degree of statistical correlation between scores on the two measures.

The Quick Inventory of Depressive Symptomatology (QIDS) is a 16-item, self-reported measure of depression that ranges from 1 (no depression) to 27 (very severe depression).

Yes
IPD Plan Description
The study will follow NIMH schedule for data sharing for clinical trials.
The schedule allows for descriptive data to be submitted - but not shared - ongoing and results associated with a finding - both positive and negative - to be submitted prior to the communication of a result.
Once a result is communicated, either through publication and/or on the NDCT website the data specifically defined to the clinical trial will then be shared.
This information was retrieved directly from the website clinicaltrials.gov without any changes. If you have any requests to change, remove or update your study details, please contact register@clinicaltrials.gov. As soon as a change is implemented on clinicaltrials.gov, this will be updated automatically on our website as well.
