Study summary

Mood disorders, such as depression and bipolar disorder, are difficult to treat. One reason is that there are no objective ways to measure how these disorders affect the body and respond to different treatments. In this study, researchers want to perform tests on people undergoing clinical care for mood disorders. The purpose is to understand the experience of receiving treatment for depression, bipolar disorder, and suicide risk. We also hope that this study will help us to predict which medications will improve thoughts of suicide.

People 18 years or older who are receiving treatment for depression, bipolar disorder, or suicide risk may take part in this study. Participants must have also been enrolled in protocol 01-M-0254.

This study will be conducted at the NIH Clinical Center in Bethesda, MD. The study typically lasts up to 12 weeks, but may last longer if a participant s treatment continues past that time.

Participants will have weekly interviews and questionnaires while they are being treated for their mood disorder. Other tests are optional and include psychological testing, blood draws, sleep tests, and imaging scans. These will be done at the start and the end of research participation.

Read the detailed description

Study Description:

This proposal would collect systematic data on individuals undergoing personalized treatments for depression, bipolar disorder and suicide risk within the Experimental Therapeutics and Pathophysiology Branch (ETPB). The ETPB recruits individuals with treatment-resistant mood disorders from around the country. After research participation, they are often offered a course of standard treatment, tailored to clinical needs, for clinical stabilization and discharge back to non-NIH clinicians. This protocol would allow for clinical ratings in-person and remotely throughout clinical standard treatments, as well as neurobiological procedures at baseline and study termination to identify potential clinical and demographic predictors and biomarkers of treatment response.

Objectives:

The primary objective is to identify predictors of antidepressant treatment response.

The secondary and tertiary objectives are to identify predictors of suicide ideation response to treatment, and biomarkers of antidepressant response to treatment, respectively.

Endpoints:

Primary Endpoint: Score on the Montgomery Asberg Depression Rating Scale

Secondary Endpoint: Score on the Scale for Suicidal Ideation

Go through the criteria one by one — yes, no or not sure — and take the list to your doctor or the study team. Kept in this browser only.

Inclusion criteria

In order to be eligible to participate in this study, an individual must meet all of the following criteria:

  • Signed consent for Protocol 01-M-0254: The Evaluation of Patients with Mood and Anxiety Disorders and Healthy Volunteers
  • Age 18 years or older
  • Able to provide
  • Able to read and write English

Exclusion criteria

EXCLUSION CRITERIA:

  • Unstable medical conditions in the opinion of the investigator that would preclude participation in outpatient or inpatient treatment.
  • Pregnancy
  • Participation in the Protocol 01-M-0254: The Evaluation of Patients with Mood and Anxiety Disorders and Healthy Volunteers, as a healthy volunteer.
  • Participants with a history of substance or alcohol abuse or dependence, or DSM-5 substance use disorder (except for caffeine, nicotine, or cannabis), or moderate to severe alcohol use disorder, within the preceding three months. In addition, participants who are currently using drugs (except for caffeine, nicotine, or cannabis) must not have used illicit substances or known drugs of abuse in the two weeks prior to consent and must have a negative drug urine test (except for prescribed benzodiazepines or stimulants) prior to enrolling in the study. Cannabis use is exclusionary if the use is daily, or if participants are unable to abstain during the study, or if function of daily life is impaired by use as determined by a clinician.
Terms in these criteria, in plain language(2)

Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.

Informed consent

Before you join, the study team explains what taking part involves — its purpose, what happens, the risks and possible benefits — and answers your questions, so you can decide freely. Consent is usually recorded on a form (the informed consent form, ICF) signed by you or, where the law allows, by someone legally authorised to decide for you.

You can keep asking questions during the study, you are told of new information that matters, and you can choose to leave at any time.

DSM diagnostic criteria

The American Psychiatric Association’s manual of mental health diagnoses. DSM-5 (2013, revised as DSM-5-TR in 2022) replaced DSM-IV, and some studies still name the older edition. “Meets DSM criteria for …” means diagnosed by that edition’s diagnostic criteria, usually by a clinician in an interview.

Individual participant data

Plan to share: Yes — Clinical and research ratings, multi-modal MRI images, MEG scans, sleep studies, physiological, behavioral, and phenotypic data collected during the study, after deidentification.

Supporting information: Statistical analysis plan

Time frame: Starting within 1 year of completion of the study

Access criteria: Participants data will only be shared if they have opted into the data share agreement. Data deposited into repositories will not be subject to any access, distribution, or reuse limitation beyond the standard procedures of the repository. Data will be uploaded to repositories listed in our NIH Intramural Research Program (IRP) Data Management and Sharing Plan. There are no restrictions on subsequent access, distribution, or reuse once the data is placed in a repository. The Branch Chief will review requests and access will need to be approved by the NIMH/DIRP SD and OCD NIMH and the NIH IRB.

What these dates mean
Start.
When the first participant enrolled; while estimated, when the study expects to open to recruitment.
Primary completion.
When the last participant was examined or treated to collect data for the study's main question, its primary outcome. A study that stopped early gives the date its data collection stopped.
Completion.
When the last participant's last visit took place, for every outcome, secondary ones and side effects included: the end of the study. Often later than primary completion, sometimes the same day.
Actual and Est.
Actual means the registry says the date has happened. Est. (estimated) is a date the sponsor plans or expects. It can still move, and the sponsor is expected to change it to actual once it has passed.
