Study of Depression-Ketamine-Brain Function

December 4, 2015 updated by: Markus KOSEL

Pilot Study Probing the Antidepressant Effects of 0.5 mg/kg Intravenous Ketamine in Drug-resistant Depressed Patients (Unipolar Depression): Efficacy, Safety, Brain Function

Targeting the glutamatergic system to treat depression is a new and promising strategy based on studies at the molecular, synaptic, and neuronal level but also on results of studies conducted in animal models and first clinical studies involving depressed patients.Ketamine has been proposed as a novel approach to induce rapid antidepressant response. In this pilot project the investigators aim to introduce this novel and promising approach into clinical practice. Besides the assessment of clinical efficacy, the investigators will put a special emphasis on the assessment of ketamine-associated effects on brain function using fMRI and cognitive testing.

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Study Type

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

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.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

18 years to 65 years (Adult, Older Adult)

Accepts Healthy Volunteers

No

Genders Eligible for Study

All

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
