Bipolar II disorder

This study tests whether gabapentin, an FDA-approved medication, can help restore the balance of key brain chemicals (GABA and glutamate) in people with bipolar disorder who also use cannabis. Participants are randomly assigned to receive either gabapentin or a placebo for 17 day…

This completed study tested Igalmi, a fast-dissolving film placed under the tongue, for managing frequent agitation in people with schizophrenia or bipolar disorder. 29 adults received the drug as needed for 7 days in a clinic. Researchers looked for signs that the drug might sto…

This study tested a personalized brain stimulation technique called accelerated intermittent theta burst stimulation (aiTBS) in 79 people with treatment-resistant depression. The goal was to see if targeting specific brain areas could ease symptoms like loss of pleasure (anhedoni…

This study looked at whether repeated ketamine infusions can help people with hard-to-treat bipolar depression stay well. 41 adults who had already responded to an initial course of ketamine received up to 6 more infusions over 12 weeks. The goal was to see if maintenance doses c…

Researchers are testing whether daily sessions with a bright light lamp can ease depressive episodes in people with bipolar II disorder. The trial compares a bright 10,000 lux lamp against a dim placebo lamp, with each session lasting 30 minutes. Participants are adults whose dep…

This study tested a fast-dissolving film (BXCL501) placed under the tongue to quickly reduce agitation in people with bipolar disorder. About 380 adults with bipolar I or II who were very agitated took part. The goal was to see if the film safely calms agitation better than a pla…

This study tested an investigational medication called BXCL501 (dexmedetomidine) given as a film under the tongue for episodes of agitation in people with schizophrenia, schizoaffective disorder, or bipolar disorder. The trial included 452 adults aged 18-75 and compared the drug …

This study tests whether bezafibrate, a drug currently used for high cholesterol, can safely improve depression in people with bipolar disorder. Thirty adults with bipolar I or II who are already on a mood-stabilizing medication will take bezafibrate for 8 weeks. Researchers will…

This study tested an accelerated schedule of theta-burst stimulation, a type of brain stimulation, in 40 people with treatment-resistant depression. Participants received multiple sessions per day targeting the left or both sides of the brain. Researchers measured changes in depr…

This study tested whether taking buprenorphine (a low-dose opioid) after a ketamine infusion can reduce suicidal thoughts more quickly and effectively than ketamine alone in people with major depression. Fifty adults participated, and researchers measured changes in suicidal idea…

This study tested an oral drug called NMRA-335140 (navacaprant) against a placebo in 18 adults with bipolar II disorder who were currently experiencing a major depressive episode. Over 6 weeks, researchers measured changes in depression symptoms using a standard rating scale. The…

This phase 2 trial tested four intravenous ketamine infusions over two weeks in 71 adults with treatment-resistant bipolar depression. Participants received either ketamine or a sedative (midazolam) to see if ketamine could quickly reduce depression symptoms. The study measured c…

This study tested a personalized form of brain stimulation for people with depression who no longer feel pleasure (anhedonia). Sixty adults received either individualized, standard, or fake magnetic pulses to the brain over one week. The goal was to see if tailoring the stimulati…

This study tested an experimental drug called ABBV-932 in 161 adults with bipolar I or II disorder who were experiencing a depressive episode. Participants took either the drug or a placebo daily for 6 weeks. Researchers measured changes in depression symptoms using standard rati…

This study tested a new medication, lumateperone, to see if it can safely ease depression in people with bipolar I or II disorder. Over 550 adults took either the drug or a placebo for six weeks. Researchers measured changes in depression symptoms using a standard rating scale.

This study tested whether a drug called esketamine works as well as electroconvulsive therapy (ECT) for quickly reducing suicidal thoughts in people with depression. 340 adults with major depression or bipolar disorder and active suicidal ideas took part. They received either esk…

This study looked at nearly 2,000 people from the community to understand how depression, anxiety, and migraine are passed down through families. Researchers interviewed family members of all ages, including children as young as 8, to track patterns of these conditions over time.…

This study looked at how well patients, their family members, and doctors agree when rating agitation episodes in people with bipolar disorder or schizophrenia. Thirty-three adults received a treatment called BXCL501, and researchers compared different questionnaires to see which…

This study looks at how lithium, a common treatment for bipolar disorder, affects the brain's wiring. Researchers will use MRI scans to track changes in brain connections over 26 weeks in 120 adults with bipolar depression. The goal is to understand why lithium works, not to test…

This study used a non-invasive brain stimulation technique called theta burst stimulation (TMS) to explore how the brain processes rewards in people with bipolar disorder. Researchers compared brain scans before and after stimulation in 146 adults, both with and without bipolar d…

This study tested whether a smartphone app that tracks how you type (speed, backspace use, autocorrect) can help monitor mood and thinking problems in people with mood disorders like depression or bipolar disorder. 132 adults aged 25-50 took part. The goal was to see if this simp…

This early-stage study tested a new oral drug, SEP-380135, in 43 adults with schizophrenia or major depression (including bipolar disorder). The main goal was to check its safety and how the body processes it. Participants took multiple doses and were monitored for side effects, …
