Detailed Description
Major depressive disorder (MDD) occurs in up to 17% of the population, is associated with profound dysfunction and, according to the WHO Global Burden of Disease Study, is estimated to become the second leading cause of disability worldwide by 2020. While antidepressants have proven efficacy, they usually take weeks to work and then only about a third of patients reach remission.
Beyond the traditional monoaminergic approaches, recent advances in understanding the pathophysiology of MDD have focused on the dysregulation of glutamate and associated neuronal glutaminergic associated excitotoxicity. Xenon is a potent antiglutaminergic agent that has been used as an anesthetic with minimal side effects, has neuroprotective effects consistent with antidepressants, and has the potential to be a novel antidepressant drug.
Although mania or hypomania are the defining characteristics of bipolar disorder, throughout the course of the illness depressive symptoms are more common than manic symptoms. People with bipolar disorder spend a substantial proportion of time with syndromal or subsyndromal depressive symptoms. The risk of suicide is greatly elevated during depressive episodes. Approximately 17% of people with bipolar I disorder and 24% with bipolar II disorder attempt suicide during the course of their illness. Annually around 0.4% of people with bipolar disorder will die by suicide, which is vastly greater than the international population average of 0.017%.
Pharmacological treatments are commonly used during episodes of mania and bipolar depression. Over time these episodes, particularly depression, tend to become more frequent and as repeated episodes are associated with increased functional impairment, effective treatment is a priority. The treatment of bipolar depression is quite challenging. Treatments used during acute episodes include antidepressants, some antipsychotic drugs such as quetiapine, the anticonvulsant drug lamotrigine and lithium. Response to these agents both acutely and during maintenance treatment is often partial. There are concerns about the potential for switching into mania and more frequent cycling mood with antidepressant treatment.
Only a handful of treatments are approved for bipolar depression and have been shown to be superior to placebo (lurasidone, valproate, quetiapine, the combination of fluoxetine and olanzapine, olanzapine alone, and lamotrigine), however atypical antipsychotics carry significant burden of side effects in particular metabolic.
Ketamine has been shown to be efficacious and well tolerated in MDD and BP depression, with low risk of inducing manic switch; other glutamatergic agents like memantine or lamotrigine are used as augmentation in depression and are well tolerated. Therefore, investigators believe Xenon could be well tolerated both in MDD and BP depression and possibly helpful in alleviating the symptoms.
The investigators hypothesize that patients with a primary diagnosis of depression will have a greater decrease in depressive symptoms after one session of xenon inhalation added to treatment as usual (X- TAU) compared to their session with nitrogen-oxygen inhalation added to treatment as usual (N-TAU). The investigators will specifically randomize the 20 patients to receive in random order one session of X- TAU and one session of N-TAU. Blind ratings of depression will be done with the modified Hamilton Depression Rating Scale (HDRS) and Quick Inventory of Depressive Symptomatology-Clinician Version (QIDS-C) at baseline and at predefined time intervals by clinicians experts in mood disorder who will be completely blinded to all the administration procedures.
The methods for depression assessments will be consistent with those used for the early proof-of-concept ketamine studies with assessments at 40, 80, 110, and 230 minutes post-administration and 1, 3, and 7 days post-administration. The primary outcome will be improvement at day 1. Mixed model repeated measures analysis will be used to compare the two groups.

- Age greater than or equal to 18 years but less than or equal to 65 years.
- Montgomery Asberg Depression Rating Scale ≥20.
- On an adequate antidepressant regimen (MDD) or on a mood stabilizing regimen (BP) that is stable for at least four weeks prior to enrollment.
- Has reliable adult transportation from and to home.
- Has a treating psychiatrist who is in agreement with the patient's participation in the study, and aware of the safety plan in the protocol.

Active Comparator: X-TAU (xenon)
Xenon is a potent antiglutaminergic agent that has been used as an anesthetic with minimal side effects, has neuroprotective effects consistent with antidepressants and has the potential to be a novel antidepressant drug. - xenon-oxygen (35:65 ratio by volume) added to treatment as usual (X-TAU group) |
The investigators have chosen to use as a maximum concentration about half the general anesthetic partial pressure of xenon (35%=70%/2) to achieve a dose that is sub-anesthetic.
This concentration of xenon is very close to that at which subjects emerging from xenon anesthesia first respond to verbal commands, commonly referred to as MAC awake.

Hamilton Depression Rating Scale (HDRS):This scale is a 6-item survey which is one of the most frequently used instruments for evaluating depression in adults, the questionnaire allows clinicians to assess the nature and severity of mood disorders in patient populations. Score Range: 0-42, higher scores means worse outcomes |

Quick Inventory of Depressive Symptomatology-Clinician Version (QIDS-C): The Quick Inventory of Depressive Symptomatology (QIDS) is designed to assess the severity of depressive symptoms. The questions to be administered by the clinician assess the severity of the nine diagnostic symptom criteria used in DSM. Score Range: 0-48, higher scores means worse outcomes |
