Biomarkers of Response to Ketamine in Depression: MRI and Blood Assays Before and After Open Label Intranasal Ketamine

Completed · Phase 2/Phase 3

Conditions studied: Depressive Disorder, Treatment-Resistant

In brief

This pilot study aims to identify predictors of response to intranasal ketamine treatment in patients with treatment-resistant depression. Participants will give a sample of blood and undergo magnetic resonance imaging before and after a single intranasal ketamine treatment. Participants will subsequently receive a second intranasal ketamine treatment.

Who can join

Age: 18 and older, up to 65. Sex: any. Healthy volunteers: not accepted.

You may qualify if…

Male or female, 18 to 65 years of age, inclusive, at screening.
Able to read, understand, and provide written, dated informed consent prior to screening. Participants will be deemed likely to comply with study protocol and communicate with study personnel about adverse events and other clinically important information.
Ability to participate in MRI (no history of claustrophobia, no presence of metallic foreign bodies incompatible with MRI, as assessed with MRI checklist and clinical interview).
Diagnosed with Major Depressive Disorders (MDD), single or recurrent, and currently experiencing a major depressive episode (MDE) of at least eight weeks in duration, prior to screening, according to the criteria defined in the Diagnosis and Statistical Manual of Mental Disorders, Fifth Edition (DSM-5). The diagnosis of MDD will be made by a site psychiatrist and supported by the Structured Clinical Interview for DSM-5 (SCID-5).
Has a history of treatment-resistant depression (TRD), as assessed by the investigator using the Mass General Hospital Antidepressant Treatment History Questionnaire (MGH ATRQ). TRD is defined as failure to achieve a satisfactory response (e.g., less than 50% improvement of depression symptoms), as perceived by the participant, to at least 1 "treatment course" of a therapeutic dose of an antidepressant therapy of at least 8 weeks duration (including the current antidepressant treatment). The adequacy of dose and duration of the antidepressant therapy will be determined as per the MGH ATRQ criteria.
Depression is of at least "moderate" severity, as determined by a Clinical Global Impression-Severity scale (CGI-S) score greater than or equal to 4).
In good general health, as ascertained by medical history, physical examination (including measurement of vital signs), clinical laboratory evaluations, and electrocardiogram (ECG).
If female, a status of non-childbearing potential or use of an acceptable form of birth control per the following specific criteria:
a. Non-childbearing potential (e.g., physiologically incapable of becoming pregnant, i.e., permanently sterilized (status post hysterectomy, bilateral tubal ligation), or is post-menopausal with her last menses at least one year prior to screening); or b. Childbearing potential, and meets the following criteria: i. Childbearing potential, including women using any form of hormonal birth control, on hormone replacement therapy started prior to 12 months of amenorrhea, using an intrauterine device (IUD), having a monogamous relationship with a partner who has had a vasectomy, or is sexually abstinent.
ii. Negative urinary pregnancy test at screening, confirmed by a negative urinary pregnancy test at baseline, prior to receiving ketamine treatment.
iii. Willing and able to continuously use one of the following methods of birth control during the course of the study, defined as those which result in a low failure rate (i.e., less than 1% per year) when used consistently and correctly: implants, injectable or patch hormonal contraception, oral contraceptives, IUD, double-barrier contraception, sexual abstinence. The form of birth control will be documented at screening and baseline.
Body mass index between 18-35 kg/m2.
Concurrent benzodiazepine therapy will be allowed if the dose is less than or equal to 2mg of lorazepam (or the equivalent) per day and stable for the past 4 weeks.

You may not qualify if…

Female of childbearing potential who is not willing to use one of the specified forms of birth control during the study.
Female that is pregnant or breastfeeding.
Female with a positive pregnancy test at screening or baseline.
Current diagnosis of a substance use disorder, except for nicotine dependence, at screening or within 6 months prior to screening.
History of bipolar disorder, schizophrenia or schizoaffective disorders, or any history of psychotic symptoms in the current or previous depressive episodes.
History of anorexia nervosa, bulimia nervosa, or eating disorder not otherwise specified, within 5 years of screening.
In the judgment of the investigator, the subject is considered at significant risk for suicidal behavior during his/her participation in the study.
Has dementia, delirium, amnestic, or any other cognitive disorder.
Has a clinically significant abnormality on the screening physical examination that might affect safety, study participation, or confound interpretation of study results according to the study clinician.
Current episode of:
Hypertension, Stage 1 as defined by a systolic blood pressure ≥160 mmHg or diastolic blood pressure ≥100 mmHg at screening (Visit 1) or within 1.5 hours prior to ketamine administration on two of three measurements (standing and supine) at least 15 minutes apart.
Recent myocardial infarction (within one year) or a history of myocardial infarction.
Syncopal event within the past year.
Congestive heart failure (CHF): New York Heart Association Criteria >Stage 2
Angina pectoris.
Heart rate <45 or >110 beats per minute at screening or Visit 3 ( first ketamine administration).
QTcF (Fridericia-corrected) ≥450 msec at screening or Visit 3 (first ketamine administration).
Chronic lung disease excluding asthma.
Lifetime history of surgical procedures involving the brain or meninges, encephalitis, meningitis, degenerative central nervous system (CNS) disorder (e.g., Alzheimer's or Parkinson's Disease), epilepsy, mental retardation, or any other disease/procedure/accident/intervention which, according to the screening clinician, is deemed associated with significant injury to or malfunction of the CNS, or history of significant head trauma within the past 2 years.
Presents with any of the following lab abnormalities:
Thyroid stimulating hormone (TSH) outside of the normal limits and clinically significant as determined by the investigator. Free thyroxine (T4) levels may be measured if TSH level is high. Subject will be excluded if T4 level is clinically significant.
Patients with diabetes mellitus fulfilling any of the following criteria:
i. Unstable diabetes mellitus defined as glycosylated hemoglobin (HbA1c) >8.5% at screening.
ii. Admitted to hospital for treatment of diabetes mellitus or diabetes mellitus-related illness in the past 12 weeks.
iii. Not under physician care for diabetes mellitus. iv. Has not been on the same dose of oral hypoglycaemic drug(s) and/or diet for the 4 weeks prior to screening. For thiazolidinediones (glitazones) this period should not be less than 8 weeks.
