About this study

Official title: Effect of Psychotherapy on Brain Serotonin Activity

This study will examine changes in brain serotonin activity in people with depression before and after they receive cognitive behavioral therapy.

Read the detailed description

Depression is a serious illness that affects almost 19 million adults in the United States each year. Common symptoms of depression include persistent feelings of anxiety, guilt, or hopelessness; irregular sleep and appetite patterns; lethargy; disinterest in previously enjoyed activities; excessive irritability and restlessness; suicidal thoughts; and inability to concentrate. A person's depression can be attributed to a variety of causes, including biological and genetic factors, environmental influences, or developmental experiences. Among biological factors, a recently researched possible cause is the altered activity of specialized areas on brain nerve cells called serotonin receptors, which have been found to be at reduced levels in people with depression. The hormone serotonin is known to naturally influence mood, making depression treatments that aim to increase levels of serotonin important. Treatment for depression with cognitive behavioral therapy (CBT), which teaches ways to modify thoughts and behaviors that contribute to depression, may help in raising brain serotonin levels and in improving depressive symptoms. This study will examine changes in brain serotonin activity using single photon emission computed tomography (SPECT) imaging in people with depression before and after they receive CBT. The study will also use SPECT imaging to compare brain serotonin activity of non-depressed healthy participants with that of depressed participants.

Participation in this study will last between 12 and 14 weeks. All participants will first undergo an initial evaluation that will include questions about medical history, a physical exam, a blood draw, a urine test, and an electrocardiogram (ECG). Participants will then undergo an ADAM (a selective radioligand for SPECT imaging) SPECT scan. During the ADAM SPECT scan visit, participants will undergo an injection of the ADAM, an ECG, blood pressure monitoring, and a 60-minute SPECT scan. If necessary, participants may also be asked to have a magnetic resonance imaging (MRI) brain scan after completing the SPECT scan.

Depressed participants will then attend at least once weekly CBT sessions for 12 weeks. During the 45-minute sessions, participants will meet with a therapist to learn ways to adjust thoughts and behaviors that may be adding to their depression. After completing the 12 weeks of CBT, all participants will be re-evaluated by a study doctor and, if still in good health, will undergo a repeat ADAM SPECT scan.

Questions about this trial

What is this clinical trial studying?

A Phase 2/3 study testing ADAM SPECT plus Cognitive Therapy and ADAM SPECT plus No Therapy in people with Depression, run by University of Pennsylvania 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 4 inclusion and 25 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 16 Apr 2020. 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. 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 16 Apr 2020). 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?

Change in Serotonin Transporter Availability (time frame: Measured at Weeks 0 and 12). It is what the study was designed to measure, not a finding.

Where can I read the original study information?
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 16 Apr 2020.
