Clinical Study of GH001 in Depression
Treatment Resistant DepressionMajor Depressive Disorder1 moreThe aim of the study is to investigate the safety of GH001 (containing 5-methoxy-dimethyltryptamine; 5-MeO-DMT), and to investigate its effects on severity of depressive symptoms, and its dose-related psychoactive effects in patients with Treatment-Resistant Depression (TRD). The study is comprised of two open-label, single-arm study parts where Part A evaluates single doses of GH001 at two dose levels and Part B evaluates a specific individualized dosing regimen of GH001.
An Expanded Access Protocol for Esketamine Treatment in Participants With Treatment Resistant Depression...
DepressionThe purpose of this expanded access program (EAP) is to provide expanded access to esketamine treatment and collect additional safety data and quality of life until esketamine is commercially available for participants with Treatment-Resistant Depression (TRD).
rTMS With and Without iCBT For the Treatment of Resistant Depression (TRD)
Depressive DisorderTreatment-ResistantThis is a prospective, two-arm randomized controlled trial. 100 patients diagnosed with resistant depression in psychiatric care clinic in Edmonton, Alberta, Canada will be randomized to one of two conditions: (1) enrolment in rTMS sessions alone (2) enrolment in the rTMS sessions plus iCBT. Patients in each group will complete evaluation measures (eg, recovery, general symptomatology and functional outcomes) at baseline, 1 month, 3 months and 6 months. The primary outcome measure would be changes to scores on the Hamilton Depression Rating Scale. Patient service utilization data and clinician-rated measures will also be used to gauge patient progress. Patient data will be analyzed with descriptive statistics, repeated measures and correlational analyses.

Treatment Resistant DepressionRandomized, two-part, placebo-controlled study of single ascending doses of NV-5138 in healthy volunteers, and a single dose of NV-5138 in subjects with Treatment-Resistant Depression (TRD)
Nitrous Oxide for Major Depressive Disorder
Depressive DisorderMajor Depressive Disorder4 moreThis study aims at investigating the persistence of antidepressant effect of Nitrous Oxide (N2O) for Treatment-Resistant Depression(TRD). The investigators also aim to assess the effect of N2O on the electroencephalograph, multimodal magnetic resonance imaging(MRI), blood cytokines, feces bacteria flora and neuropsychological performance in patients with TRD. The investigators further aim to identify the predictors of N2O's antidepressant effeect using the above techniques.
Implementation Trial of Evidence Based Practices for Mood Disorders
Bipolar DisorderTreatment Resistant DepressionThe objective of this Implementation Trial is to evaluate the implementation of evidence based practices for Bipolar Disorder and Treatment Resistant Depression in small rural Federally Qualified Health Centers. The evidence based practices chosen and adapted by Health Center providers and patients in consultation with clinical experts include: screening for and diagnosing Bipolar Disorder, prescribing mood stabilizers, on-line cognitive behavioral therapy, on-line peer support, collaborative care management and tele-psychiatry consultation. A quasi-experimental study design will be used, with each of the six participating Federally Qualified Health Centers choosing one implementation clinic and one control clinic. Implementation outcomes include: reach, adoption, implementation-fidelity and effectiveness. Providers and patients may choose to use all, any or none of the evidence based practices based on their needs and preferences. Data will be collected from chart review and patient surveys will be administered by an Interactive Voice Response telephone system.
