Study Overview

This clinical trial focuses on testing the efficacy of different digital interventions to promote re-engagement in cancer-related long-term follow-up care for adolescent and young adult (AYA) survivors of childhood cancer.

Description

Background: Major depressive disorder (MDD) is a psychiatric condition. People with MDD have occasional bouts of depressive symptoms; these bouts are called major depressive episodes (MDEs). Researchers want to know if people having MDEs have lower levels of an enzyme called PDE4B in their brains. Primary Objective: To determine whether PDE4B is reduced in the brains of individuals with MDD experiencing a major depressive episode (MDE). Secondary Objectives: To determine the optimal length of scanning and the retest variability and reliability of \[18F\]PF-06445974, and whether PDE4B binding correlates with clinical rating scales. To measure if PDE4B radioligand binding can be blocked by taking apremilast. Eligibility: People aged 18-70 years with MDD. Healthy volunteers are also needed. Design: Participants will have up to 5 clinic visits. Participants will be screened. They will have a physical exam with blood tests. They will have a test of their heart function. Some participants may have a psychiatric assessment; they will answer questions about their state of mind and related topics. Participants will have magnetic resonance imaging (MRI) of the brain. They will lie on a table that slides into a metal cylinder. Participants will have a positron emission tomography (PET) scan. A needle will be used to guide a thin plastic tube (catheter) into a vein in one arm. An experimental substance called a radioactive tracer (\[18F\]PF-06445974) will be injected through the catheter. Participants will lie on a table that slides into a doughnut-shaped machine. The scan will last up to 4 hours with a 15-minute break. Participants blood pressure, heart rate, and breathing will be monitored before, during, and after the PET scan. A second catheter will be inserted in the artery of the wrist so blood can be drawn during the scan. Some participants may return for a second PET scan; have a lung scan or receive apremilast. https://nimhcontent.nimh.nih.gov/start/surveys/?s=KE88DXXPLDFHHTF8

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Ages Eligible for Study:18 Years to 70 Years
Sexes Eligible for Study:ALL
Accepts Healthy Volunteers:Yes
Standard Ages:ADULT, OLDER_ADULT
Inclusion CriteriaExclusion Criteria
  1. * 18 to 70 years of age.
  2. * Female participants of childbearing potential must be using a medically acceptable means of contraception.
  3. * Be in good general health as evidenced by medical history and physical examination. Stable medical conditions as assessed by their primary care provider (PCP) and/or in-house clinician are permitted to join the study.
  4. * Each participant must have a level of understanding sufficient to agree to all required tests and examinations and sign an informed consent document.
  5. * All participants must have undergone a screening assessment under protocol 01-M-0254, The Evaluation of Patients with Mood and Anxiety Disorders and Healthy Participants .
  6. * Participants must fulfill DSM-5 criteria for major depression (MDD) without psychotic features, as based on clinical assessment and structured diagnostic interview (SCID-P).
  7. * Participants must have an initial score on the MADRS \>= 18 or HAM-D \>= 15 within one week of study entry.
  8. * Participants must be experiencing an MDE lasting at least four weeks.
  9. * All MDD participants must have a PCP or psychiatrist in the community.
  10. * Participants must have their radial artery pulse checked for the presence of adequate ulnar collateral flow and the absence of any metal or foreign objects in both wrists.
  11. * Participants must agree to adhere to the lifestyle considerations.
  12. * Aged 18 to 70 years old.
  13. * Female participants of childbearing potential must be using a medically acceptable means of contraception.
  14. * Able to provide informed consent.
  15. * Be in good general health, as evidenced by medical history and physical examination, and have no cognitive impairment.
  16. * Be enrolled in 01M0254, The Evaluation of Participants with Mood and Anxiety Disorders and Healthy Volunteers or 17M0181, Recruitment and Characterization of Healthy Research Volunteers for NIMH Intramural Studies .
  17. * Have their radial artery pulse checked for the presence of adequate ulnar collateral flow and the absence of any metal or foreign objects in both wrists.
  18. * Agree to adhere to the lifestyle considerations.
  1. * Clinically significant abnormalities on EKG or laboratory testing. This includes CBC and acute care panel (Na, K, Cl, CO2, creatinine, glucose, urea nitrogen). Any lab value that is two-times the upper limit or even lower values in the investigator s judgment. Creatinine level \>1.3 mg/dL.
  2. * Participants must be free of all prohibited medications for at least two weeks (5 weeks for aripiprazole, brexpiprazole, fluoxetine) prior to screen visit. These medications include antidepressants, antipsychotics, anxiolytics, psychotropic drugs not otherwise specified
  3. * Current psychotic features, a diagnosis of schizophrenia or any other psychotic disorder as defined in the DSM-5.
  4. * Participants with a history of psychiatric inpatient hospitalization within the past year.
  5. * Participants with a history of DSM-5 substance use disorder (except for caffeine or nicotine dependence) within the preceding three months. In addition, participants must not have substance use disorder or alcohol use disorder. However, alcohol or cannabis use by themselves are not exclusion criteria, unless that use impairs function of daily life.
