Supportive and Supportive-Expressive Treatment for Depression
Major Depressive DisorderThis study will assign patients to two types of psychotherapies in treating people with a major depression disorder, expressive versus supportive techniques, and will examine their ability to benefit from treatment based on their attachment orientation. This is a four month protocol, with a year follow up period, will compare patients receiving supportive-expressive treatment with either expressive focus or supportive focus.
Ketamine for the Rapid Treatment of Major Depressive Disorder and Alcohol Use Disorder
Major Depressive DisorderAlcohol Use DisorderThe investigators will compare 3 treatment groups (ketamine plus naltrexone vs. ketamine alone vs. placebo) for treating major depressive disorder (MDD) and alcohol use disorder (AUD) in an 8-week randomized, double-blind, placebo-controlled, between-subjects trial. First, prior to the double-blind trial, the investigators will conduct an open-label trial that will include 5 patients with comorbid MDD and AUD to test safety and efficacy of repeated ketamine treatment (0.5 mg/kg; once a week for 4 weeks; a total of 4 ketamine infusions) with a follow-up of 4 weeks. Second, after reviewing the safety and efficacy of repeated ketamine treatment from the open-label trial, the investigators will conduct an 8-week, randomized, double-blind, placebo-controlled trial that will include 60 patients with comorbid MDD and AUD to test safety and efficacy of repeated ketamine treatment (0.5 mg/kg; once a week for 4 weeks; a total of 4 ketamine infusions) plus naltrexone with a follow-up of 4 weeks. The 4-month follow-up session will also occur.
NESBID: Neuro-Stimulation of the Brain in Depression
Depressive DisorderMajor4 moreIn Canada, approximately 20% of patients with Major Depressive Disorder (MDD) have treatment-resistance and fail to respond to trials of pharmacotherapy or psychotherapy. Although the treatment of choice has historically consisted of electroconvulsive therapy (ECT), this is not always feasible or practical, and carries a risk of side-effects that may be unacceptable to certain patients. In this pragmatic, multi-site, placebo-controlled and double-blinded clinical trial, participants with ultra treatment-resistant MDD will be randomized to receive either active or sham transcranial direct current stimulation in addition to their usual treatment. Ultra treatment-resistant depression will be operationally defined as MDD that has failed to respond to at least five previous trials of antidepressants at sufficient doses, or ECT, or ketamine. Patients will receive a total of 30 active or sham treatment sessions (5 per week), for 30 minutes per session. In both groups, the anode will be placed over the left dorsolateral prefrontal cortex (position F3), and the cathode over the right dorsolateral prefrontal cortex (position F4). Patients in the sham group will receive electrical stimulation at 2 mA for less than 30 seconds, whereas patients in the active group will receive that level of stimulation for the entire duration of treatment. The study's primary outcome is the change in score on a clinician-graded depression inventory (the Montgomery-Asberg Depression Rating Scales). Secondary outcomes include change in scores on a self-administered depression rating scale and measurement of function scale. Information on language ability will also be collected, as will data on side-effects of treatment. Scores will be collected before the trial start, after every 10 sessions, and one month after trial completion.

Phase 1 Evaluation of (2R,6R)-Hydroxynorketamine
Major Depressive DisorderA 6-cohort single ascending dose (SAD) study will be conducted in healthy volunteers utilizing a slow-infusion intravenous (IV) route of administration. Standard safety, pharmacokinetics (PK) and qEEG monitoring will be evaluated at all dose levels. Subsequently, a 2-cohort multiple ascending dose (MAD) study will be conducted. Doses will be administered on days 1, 4, 8, and 11. Standard safety parameters will be monitored, and PK will be evaluated at all dose levels. Finally, a single-cohort group with received a single dose by slow-infusion IV and have PK samples collected from both blood and cerebrospinal fluid (CSF).
Repurposing of Dextromethorphan as an Adjunct Therapy in Patients With Major Depressive Disorder...
Major Depressive DisorderTherapeutic latency, lack of efficacy, and adverse drug reactions are the major concerns in current antidepressant therapies. One-third of the patients with major depressive disorder do not respond to conventional antidepressants that act through the monoaminergic system. To overcome these treatment hurdles, add-on therapy to standard antidepressant drugs may lead to better therapeutic outcomes. The recent discovery of the rapid and sustained antidepressant effect of subanesthetic dose of ketamine led to many extensive clinical and preclinical research in the recent past and has established the possibilities of NMDA receptors as a potential drug target for depression. As repeated doses of ketamine are related to abusive potential and adverse effects, the search for a similar antidepressant agent with a better safety profile is essential. Dextromethorphan has the property of noncompetitively blocking N-methyl-D-aspartate receptors (like ketamine) with additional serotonin transporter and norepinephrine transporter inhibitory action. So, the investigators expect that adding dextromethorphan to selective serotonin reuptake inhibitors (SSRIs) regimen can improve clinical outcomes in major depressive disorder. The literature search found that to date, there is no randomized controlled trial on Dextromethorphan as add-on therapy to first-line antidepressants like SSRIs. So, the present randomized controlled trial has been planned to evaluate the efficacy and safety of add-on dextromethorphan to SSRIs in major depressive disorder.

MARt-Depression Trial
Major Depressive DisorderThis is an open label pilot feasibility study that will recruit 15 participants. The purpose of the pilot study will be to evaluate the feasibility of open label Transcranial direct current stimulation (tDCS) in combination with computerized cognitive behavior therapy (cCBT) to maintain wellness following an acute course of Electroconvulsive therapy (ECT) for up to 6 months.
