NCT03102736

Brief Summary

The purpose of this study is to test the effects of the medication ketamine and the medication called nitroprusside in patients with major depression. Ketamine has both good and bad effects. Some studies have shown that ketamine improves depression. However, studies have also shown that it causes strange and sometimes unpleasant sensations referred to "psychotic" or "dissociative" symptoms. An example of a psychotic symptom would be hearing or seeing something that in reality is not there. The study team would like to see if nitroprusside can prevent the reported bad effects of ketamine without blocking the reported good effects. This might make ketamine a better treatment for depression.

Outcome Measures

Primary Outcomes (1)

  • Montgomery-Asberg Depression Rating Scale

    This is a 10-item instrument used for the evaluation of depressive symptoms in adults and for the assessment of any changes to those symptoms. Each of the 10 items is rated on a scale of 0 to 6, with differing descriptors for each item. These individual item scores are added together to form a total score, which can range between 0 (normal) and 60 (severe depression).

    24 hours after start of infusion

Secondary Outcomes (3)

  • Clinician-Administered Dissociative States Scale

    240 minutes after start of infusion

  • Visual Analog Scale

    240 minutes after start of infusion

  • Brief Psychiatric Rating Scale (BPRS)

Healthy VolunteersNo
Age GroupsAdult (18-64), Older Adult (65+)

You may qualify if:

  • Male or female patients, 21-65 years of age;
  • 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-infusion;
  • Participants must fulfill current DSM-5 criteria for Major Depression without psychotic features or Persistent Depressive Disorder with specifier of "with persistent major depressive episode";
  • Depression is at least moderate severity, defined as a CGI-S score of ≥ 4;
  • Current major depressive episode is of at least 4 weeks duration
  • 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
  • Each participant must be able to identify a family member, physician, or friend who will act as an emergency contact

You may not qualify if:

  • Lifetime history of psychotic features, diagnosis of schizophrenia or any other psychotic disorder, or diagnosis of bipolar disorder;
  • Lifetime histories of autism, mental retardation, pervasive developmental disorders, or Tourette's syndrome;
  • Current diagnosis of obsessive compulsive disorder (OCD) or eating disorder (bulimia nervosa or anorexia nervosa);
  • Subjects with DSM-V drug or alcohol abuse/dependence within the preceding 2 years;
  • 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;
  • Patients judged clinically to be at serious and imminent suicidal or homicidal risk;
  • Women who are either pregnant or nursing;
  • Any serious, unstable medical illnesses including hepatic, renal impairment, gastroenterologic, respiratory, cardiovascular, endocrinologic, neurologic, immunologic, or hematologic disease;
  • History of congestive heart failure or established coronary artery disease;
  • History of cerebrovascular insufficiency
  • History of intrapulmonary arteriovenous shunts, co-arctation of the aorta or other conditions where cardiac outflow tract is obstructed;
  • Vitamin B12 deficiency;
  • Clinically significant abnormal findings of laboratory parameters, physical examination, or ECG;
  • Renal impairment, as reflected by a BUN \> 20 mg/dL and/or creatinin clearance of \>1.3 mg/dL;
  • Thyroid impairment, as reflected by a thyroid-stimulating hormone (TSH) \> 4.2 mU/L;
  • +7 more criteria
