Brief Summary:

Existing treatments for major depressive disorder (MDD) generally take weeks to months to exert their maximal benefit. There is an urgent need to develop rapid-acting treatments for MDD. Ketamine, a high-affinity N-methyl-D-aspartate (NMDA) glutamate receptor antagonist, has been used as a standard intravenous (IV) anesthetic agent for many years in both pediatric and adult patients. Beyond its well-established role in anesthesia and pain management, there is emerging evidence that ketamine may have rapid antidepressant properties for patients with severe mood disorders.

In this study we are investigating whether ketamine can have an antidepressant effect compared to midazolam. Midazolam has similar anesthetic effects compared to ketamine but has not been shown to be an antidepressant, and is therefore acting as an active control in this study.

The study period can last up to 8 weeks, depending on your response to the study medication. There are two required overnight stays in our Research Commons as part of this study.

Arm Intervention/treatment
Experimental: 1
Drug: Ketamine
Single dose .5 mg/kg IV (in the vein) infused over 40 minutes
Other Name: Racemic ketamine hydrochloride

Active Comparator: 2
Drug: Midazolam
single dose 0.045 mg/kg IV infused over 40 minutes

Primary Outcome Measures :
  1. MADRS [ Time Frame: 24 hours post-infusion ]
    Montgomery-Asberg Depression Rating Scale, each of the ten items can be scored from 0 (absence of symptoms to 6 most severe) and has a total score range of 0-60. A lower score on a MADRS indicates a less severe depression.

Sexes Eligible for Study:   All
Accepts Healthy Volunteers:   No

Inclusion Criteria:

  1. Male or female patients, 21-80 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 serum beta-human growth hormone at screening and at pre-infusion;
  3. Participants must fulfill DSM-IV criteria for Major Depression without psychotic features, based on clinical assessment by a study psychiatrist and confirmed by a structured diagnostic interview, the Structured Clinical Interview for DSM-IV TR Axis I Disorders, Patient Edition (SCID-P);
  4. Participants must have a history of at least one previous episode of depression prior to the current episode (recurrent MDD) or have chronic MDD (of at least two years' duration);
  5. Participants have not responded to three or more adequate trials of an antidepressant as determined by Antidepressant Treatment History Form (ATHF) criteria (score >=3);
  6. Participant scores on the IDS-C30 must be greater than or equal to 32 at both Screening and within 24 hours prior to Visit 1a (Phase 1);
  7. Current major depressive episode is of at least 4 weeks duration.
  8. 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;
  9. Each participant must be able to identify a family member, physician, or friend who will participate in the Treatment Contract.

Exclusion Criteria:

  1. Lifetime history of psychotic features, diagnosis of schizophrenia or any other psychotic disorder, or diagnosis of bipolar disorder
  2. Lifetime histories of autism, mental retardation, pervasive developmental disorders, or Tourette's syndrome;
  3. Current diagnosis of Obsessive Compulsive Disorder or eating disorder (bulimia nervosa or anorexia nervosa);
  4. Subjects with DSM-IV drug or alcohol abuse/dependence within the preceding 2 years;
  5. Patients with schizotypal or antisocial personality disorder, or any clinically significant axis II disorder that would, in the investigator's judgment, preclude safe study participation;
  6. Patients judged clinically to be at serious and imminent suicidal or homicidal risk;
  7. Women who are either pregnant or nursing;
  8. Serious, unstable medical illnesses including hepatic, renal, gastroenterologic (including gastroesophageal reflux disease), respiratory (including obstructive sleep apnea, or history of difficulty with airway management during previous anesthetics), cardiovascular (including ischemic heart disease and uncontrolled hypertension), endocrinologic, neurologic (including history of severe head injury), immunologic, or hematologic disease;
  9. Clinically significant abnormal findings of laboratory parameters, physical examination, or ECG;
  10. Patients with one or more seizures without a clear and resolved etiology;
  11. Patients starting hormonal treatment (e.g., estrogen) in the last 3 months prior to Visit 1a;
  12. Treatment with an irreversible MAOI or any other FDA approved Anti depressant medication within one week prior to Visit 1a (with the exception of a stable dose of non-benzodiazepines hypnotics i.e. zolpidem, eszopiclone, etc for at least 3 months);
  13. Treatment with fluoxetine within 4 weeks prior to Visit 1a;
  14. Evidence-based individual psychotherapy (e.g. CBT or IPT) and other non-pharmacological antidepressant treatments (e.g. light therapy) will not be permitted during the acute study period (7 day);
  15. Previous recreational use of PCP or Ketamine.
  16. Past intolerance or hypersensitivity to midazolam
  17. Hypertension (systolic BP >160 mm Hg or diastolic BP >90 mm Hg) not controlled by diuretic or beta-blocker therapy alone or in combination.
  18. Evidence of age-related cognitive decline or mild dementia suggested by a score of < 27 on the Mini-Mental State Examination (MMSE) at Screening
