    To address the significant need for effective treatment of suicidal ideation in Veterans, this trial is designed as an open label pilot study of intranasal ketamine in 15 people.

    Participant Groups

    • Subjects will receive study medication, intranasal ketamine.

    Eligibility Criteria

    Sex: All
    Minimum Age: 21
    Maximum Age: 70
    Age Groups: Adult / Older Adult
    Healthy Volunteers: Yes

    Inclusion Criteria:

    1. Male or female patients, 21-70 years of age
    2. Female individuals who are not of childbearing potential (i.e., surgically sterile, postmenopausal for at least one year) or using a medically accepted reliable means of contraception. Women using oral contraceptive medication for birth control must also be using a barrier contraceptive. Women of childbearing potential must also have a negative pregnancy test at screening and at pre-administration
    3. Any non-psychotic disorder diagnosis
    4. Score \>4 on the suicide item of the Montgomery-Asberg Depression Rating Scale (MADRS-SI; range 0-6)for clinically significant suicidal ideation or past suicide attempts
    5. Each participant must have a level of understanding sufficient to agree to all tests and examinations required by the protocol and must sign an informed consent document
    6. Each participant must agree to avoid future enrollment in ketamine trials.

    Exclusion Criteria:

    1. current psychotic symptoms or lifetime history of primary psychotic disorder
    2. active substance use in the preceding two weeks or needing medical attention for withdrawal
    3. neurodevelopmental disorder (e.g., ASD)
    4. major neurocognitive disorder (e.g., Alzheimer's type dementia)
    5. serious cardiac disease
    6. suicide attempt precipitating current admission requiring medical stabilization
    7. Lifetime histories of autism, mental retardation, pervasive developmental disorders, or Tourette's syndrome
    8. Women who are either pregnant or nursing
    9. Hypertension (systolic BP \>160 mm Hg or diastolic BP \>90 mm Hg) at screening or immediately prior to treatment with study drug
    10. Previously received ketamine for refractory depression.

    Primary Outcomes
    • Beck Scale is a 21-item self or clinician administered instrumentation used to measure the current intensity of patients' specific attitudes, behaviors and plans to commit suicide. Score range 0-42, with higher score indicating higher intensity.

    Secondary Outcomes
    • The MADRS is a 10-item instrument used for the evaluation of depressive symptoms in adults and for the assessment of any changes to those symptoms. Higher MADRS score indicates more severe depression, and each item yields a score of 0 to 6. The overall score ranges from 0 to 60.

    • QIDS-SR is a 16-item self-rated instrument designed to assess the severity of depressive symptoms present in the past seven days (Rush et al. 2003). The 16 items cover the nine symptom domains of major depression, and are rated on a scale of 0-3.
