Elucidating the Neurocircuitry of Irritability With High-Field Neuroimaging to Identify Novel Therapeutic Targets (UNIKET)
The study is investigating dysfunctions in neurocircuitry in regards to irritability with healthy controls (HC) and individuals with Major Depressive Disorder (MDD) by performing MRIs. The MDD group will also be randomized to receive ketamine or midazolam to investigate changes post-treatment in neurocircuitry with regards to irritability.

• For Healthy Controls: Subjects must be free of any lifetime psychiatric condition based on the Mini-International Neuropsychiatric Interview (MINI). For MDD: Subjects must meet Diagnostic and Statistical Manual of Mental Disorders (DSM-5) criteria for current unipolar depression [major depressive disorder (MDD) or persistent depressive disorder (PDD) in a current major depressive episode (MDE)] based on MINI.
• A woman of childbearing potential who is sexually active with a male must agree to use an acceptable method of contraception [defined as either one highly effective (permanent sterilization, intrauterine device or hormonal implant) or two other forms of contraception (such as oral contraceptive pill and condom)] to avoid pregnancy throughout the study. Throughout the study and for 90 days (one spermatogenesis cycle) after receiving the last dose of study drug (ketamine/midazolam) man who is sexually active with a woman of childbearing potential must use an acceptable method of contraception (described above) with his female partner and must agree not to donate sperm.
• Subjects must either be free of psychotropic medications (including antidepressants, antipsychotics, benzodiazepines, mood stabilizers, sedative/hypnotics, dopamine agonists, stimulants, buspirone, and triptans) and certain anticonvulsants (topiramate and levetiracetam) or be stable on these medications for four weeks prior to the baseline visit [first magnetic resonance imaging (MRI) scan].
• Subjects with MDD should be willing to participate in neuroimaging scans before and after infusions, and be willing to undergo infusions with study drug.
Exclusion Criteria:
• Lifetime diagnosis of schizophrenia or any psychotic disorder, bipolar disorder, pervasive developmental disorder or intellectual development disorder.
• Current diagnosis of obsessive-compulsive disorder, anorexia nervosa or bulimia. Comorbid anxiety, stress and trauma-related disorders are permitted as long as unipolar depression is the primary diagnosis.
• Diagnosis of a moderate or severe substance use disorder within the past 6 months per MINI; all subjects must have a negative urine toxicology test on the day of the MRI, prior to the scan.
• Female subjects who are pregnant, nursing, for may become pregnant. Women of childbearing potential must have a negative urine pregnancy test on the day of the fMRI, prior to scan, and on days of study drug infusion, prior to infusion.
• Any unstable medical illnesses including hepatic, renal, gastroenterologic, respiratory, cardiovascular (including ischemic heart disease), endocrinologic, immunologic, or hematologic disease.
• Inadequately treated obstructive sleep apnea (STOP-Bang score of 5-8 if untreated, if using positive airway pressure device then past-month apnea hypopnea index ≥ 15 per hour representing moderate or higher severity).
• Presence of a significant neurological disease such as Parkinson's disease, primary or secondary seizure disorders, intracranial tumors, or severe head trauma.
• Presence of neurocognitive or dementing disorders.
• Clinically significant abnormalities of laboratories, physical examination (including unstable hypertension - systolic blood pressure >170, diastolic blood pressure >100), or electrocardiogram at screening visit.
• Subjects judged to be at serious and imminent suicidal or homicidal risk by the PI or another study-affiliated psychiatrist.
• Any contraindications to MRI, including pacemakers or metallic objects in the body.
• Any claustrophobia or other conditions which may result in inability to lie still in the MRI scanner for 1 hour or more.
• Allergy to ketamine or midazolam in subjects with MDD.
• Must not be on any prohibited concomitant medication.

Ketamine Versus Midazolam for Recurrence of Suicidality in Adolescents
This project aims to examine the efficacy of ketamine, a rapidly acting medication shown to decrease suicidality in adults in as short as hours or days, as opposed to weeks. The study design is a double-blind, randomized, active-control trial of adolescents (ages 13-18 years) with recent suicidal behaviors (suicide attempt or increased suicidal ideation). All participants must be receiving standard of care treatment which may range broadly from both outpatient and inpatient programs which include clinically indicated psychosocial and/or psychopharmacological treatments. Ketamine/midazolam treatment will occur twice weekly during the first two weeks of the study, followed by weekly assessments through week 12.

Inclusion Criteria
Study participants must:
• Be adolescents (aged 13-18 years);
• Have had a recent suicidal event (suicide attempt or significant suicidal ideation with a plan or intent warranting emergency evaluation or inpatient hospitalization within the past 90 days);
• Receiving standard of care treatment that includes clinically indicated psychosocial and/or psychopharmacological treatment;
• Have a current primary diagnosis of a depressive disorder based on the MINI-KID (other psychiatric disorders are acceptable, but must not be primary);
• Both participants and their designated caregiver must be able to complete assessments in English, as the rating scales vital to study efficacy and safety evaluations have not been validated in Spanish. (NOTE: Most potential participants ages 13 to 18 years old, as well as most of their parents, have a good working knowledge of English);
• Use effective method of contraception during and for 90 days following the end of treatment for female and male participants. Recommended methods of birth control are namely, consistent use of an approved hormonal birth control (pill/patches, rings), an intrauterine device (IUD), contraceptive injection, double barrier methods, sexual abstinence, or sterilization; Exclusion Criteria Study participants must not:
• Have a psychotic disorder, such as lifetime schizophrenia, or a pervasive or intellectual developmental disorder requiring substantial or very substantial support;
• Have current mania, hypomania, mixed episode, or obsessive-compulsive disorder;
• Have a primary diagnosis other than a depressive disorder;
• Have moderate to severe alcohol or substance use disorder within the past six months (based on MINI-KID); If there is a positive urine drug screen at screening, the urine drug screen will be repeated at each infusion visit. Positive urine drug screen will be reviewed by study physician and infusion will proceed as long as no safety risk was identified;
• If female, be pregnant, lactating, or nursing; Women of childbearing potential must have a negative urine pregnancy test prior to all infusions;
• Have unstable medical conditions (stable for less than 3 months) or with clinically significant laboratory values or an electrocardiogram (ECG) that would pose significant risk;
• Be at serious suicidal risk that cannot be managed in the outpatient setting;
• Have prior treatment for depression with or contraindications to ketamine, esketamine, or, midazolam;
• Treatment with medications that may alter pharmacokinetics of ketamine, including moderate-to-strong inhibitors or inducers of CYP3A4 and CYP2B6, is exclusionary. Regarding pharmacodynamic interactions, medications that may increase heart rate or blood pressure such as the ADHD stimulant medications will be permitted with last dose at least 24 hours prior to infusion. All concomitant medications will be evaluated by the study physician to determine if the type and dose of concomitant medication requires discontinuation and will be excluded if the concomitant medication could substantially increase the risk of study infusion. A complete list of medications that are Not Allowed is available in Appendix D of the protocol. The study team will not ask the participant to discontinue any treatment (except for not taking ADHD medications for 24 hours before study treatment) just for the sake of taking part in this study;
