Natural History of Depression, Bipolar Disorder and Suicide Risk

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.

Investigation of the Antidepressant Effects of (2R,6R)-HNK, an Enhancer of Synaptic Glutamate Release, in Treatment-Resistant Depression

Background: Major depressive disorder (MDD) is a serious mental illness that can put people at risk of self-harm and death. Many drugs are used to treat MDD, but it can take a long time for them to be effective. Researchers want to know if a faster-acting drug, (2R,6R)-hydroxynorketamine (HNK), can better treat the symptoms of MDD. Objective: To test a study drug (HNK) in people with MDD. Eligibility: People aged 18 to 70 years with MDD. They must have had a screening assessment under protocol 01-M-0254. Design: Participants will be tapered off their current MDD drugs over 2 to 5 weeks. They will stay off of the drugs for up to 2 weeks prior to starting the study medication and procedures. They will have a physical exam with blood tests. They will have tests of their heart function, mood, and thinking. They will answer questions about their symptoms. They may choose to have imaging scans and scans of their brain activity. HNK is given through a tube attached to a needle inserted into a vein. Participants will receive infusions on this schedule: They will receive 4 infusions over 2 weeks. They will stay in the clinical center overnight after each infusion or for the duration of the study. They will receive no drugs for 2 to 3 weeks. They will have 4 more infusions over 2 weeks, with overnight stays after each or for the duration of the study. One set of 4 infusions will be the HNK. The other set of 4 infusions will be a placebo. A placebo looks just like the real drug but contains no medicine. Participants will not know when they are getting the HNK or placebo. ...
