Neuropharmacologic Imaging and Biomarker Assessments of Response to Acute and Repeated-Dosed Ketamine Infusions in Major Depressive Disorder

ClinConnect Summary

This clinical trial is studying the effects of ketamine, a medication that has been shown to quickly help with depression, to see how it can be used more effectively. The main goal is to understand how ketamine can treat major depressive disorder, especially for people who haven’t responded well to other treatments. Researchers will also look at how ketamine changes brain chemistry by examining substances created when the body breaks down the medication.

To participate, you need to be between 18 and 65 years old and either have major depressive disorder or be a healthy volunteer. Participants will spend time at the National Institutes of Health (NIH) for around 14-20 weeks, undergoing various tests including brain scans, mood assessments, and receiving ketamine infusions. Throughout the study, researchers will monitor your mood and other health factors. Importantly, if you have certain medical conditions or a history of substance abuse, you may not be eligible to participate. This study aims to provide new insights into rapid treatments for depression, which could be a significant breakthrough for many people suffering from this condition.

Eligibility criteria

• * INCLUSION CRITERIA:
• • Inclusion Criteria: All Subjects (Main Study)
• • 1. 18 to 65 years of age.
• • 2. Each subject must have a level of understanding sufficient to agree to all required tests and examinations and sign an informed consent document.
• • 3. All subjects must have undergone a screening assessment under either protocol 01-M-0254, "The Evaluation of Patients with Mood and Anxiety Disorders and Healthy Volunteers" or protocol 17-M-0181 ("Recruitment and Characterization of Research Volunteers for NIMH Intramural Studies").
• • 4. Agree to be hospitalized
• • Additional Inclusion Criteria: Patients with MDD (Main Study)
• • 1. At the initial study enrollment, subjects must have fulfilled DSM-IV or DSM-V criteria for Major Depression, single episode or recurrent. Subjects must be experiencing a current major depressive episode of at least 2 weeks duration.
• • 2. At the initial screening and beginning of Phases II and III, subjects must have a baseline score on the MADRS greater than or equal to 20 and YMRS of \< 12.
• • 3. Current or past history of lack of response to one adequate antidepressant trial, operationally defined using the Antidepressant Treatment History Form (ATHF); a failed adequate trial of ECT would count as an adequate antidepressant trial.
• • Ketamine Metabolites Substudy Inclusion Criteria: Healthy Volunteers
• • 1. 18 to 65 years of age.
• • 2. Each subject must have a level of understanding sufficient to agree to all required tests and examinations and sign an informed consent document.
• • 3. All subjects must have undergone a screening assessment under either protocol 01-M-0254, "The Evaluation of Patients with Mood and Anxiety Disorders and Healthy Volunteers") or 17-M-0181 ("Recruitment and Characterization of Research Volunteers for NIMH Intramural Studies").
• • 4. Agree to be hospitalized.
• EXCLUSION CRITERIA:
• • Additional Exclusion Criteria: Patients with MDD (Main Study)
• • 1. Current diagnosis of Bipolar Disorder including Bipolar I, Bipolar II, or Bipolar NOS diagnoses.
• • 2. Current psychotic features or a diagnosis of Schizophrenia or any other psychotic disorder as defined in the DSM-IV or DSM-V.
• • 3. Subjects with a history of DSM-IV or DSM-V drug or alcohol dependency or abuse (except for caffeine or nicotine dependence) within the preceding 3 months. In addition, subjects who currently are using drugs (except for caffeine or nicotine) must not have used illicit substances or known drugs of abuse in the 2 weeks prior to screen and must have a negative alcohol and drug urine test (except for prescribed benzodiazepines or stimulants) urine test at screening.
• • 4. Treatment with a reversible MAOI within two weeks prior to Phase II.
• • 5. Subjects who, in the investigator s judgment, pose a current serious suicidal or homicidal risk.
• • Exclusion Criteria: All Subjects (Main Study)
• • 1. Pregnant or nursing women or women who plan to become pregnant. Women who are able to get pregnant must be willing to use at least one form of effective birth control during the entire period of study participation (or until last clinical labs and rating) and have a negative pregnancy test that was obtained no more than 24 hours prior to MRI and infusion of ketamine.
• • 2. Serious, unstable illnesses including hepatic, renal, gastroenterologic, respiratory, cardiovascular (including ischemic heart disease, coronary artery disease, atherosclerotic ischemic stroke, and atrial fibrillation), endocrinologic, neurologic, immunologic, or hematologic disease.
• • 3. Clinically significant abnormal laboratory tests.
• • 4. Subjects with one or more seizures without a clear and resolved etiology or current use of medication known to lower seizure threshold. History of seizure (regardless of age or etiology), history of epilepsy in self or first-degree relatives, stroke, brain surgery, head injury, or known structural brain lesion will be excluded from the TMS procedures.
• • 5. Treatment with any other concomitant medication 14 days prior to Phase II. An exception of this would be necessary for those who are taking Fluoxetine or Aripiprazole. Prior to Phase II, treatment with Fluoxetine must be discontinued for at least 5 weeks and treatment with Aripiprazole must be discontinued for at least 3 weeks.
• • 6. Any use of opioid medication in the past 3 months
• • 7. Presence of metallic (ferromagnetic) implants (e.g, heart pacemaker, aneurysm clip) (for subjects doing imaging component of the study only).
• • 8. Presence of any medical illness likely to alter brain morphology and/or physiology (e.g., hypertension, diabetes) even if controlled by medications.
• • 9. Subjects who have hearing loss that has been clinically evaluated and diagnosed
• • 10. Participants who are uncomfortable in small closed spaces (have claustrophobia), unable to lie comfortably supine for up to 90 minutes, and would feel uncomfortable in the MRI machine (for subjects doing imaging component of the study only).
• • 11. Positive HIV test
• • 12. Weight \> 119 kg
• • 13. A current NIMH employee/staff or their immediate family member

• • 1. Current or past history of any DSM-IV or DSM-V Axis I disorder based on clinical assessment and confirmed by a structured diagnostic interview (SCID).
• • Ketamine Metabolites Substudy Exclusion Criteria: Healthy Volunteers
