Who can join

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

You may qualify if…

• Male or female subject aged between 18 and 65 at screening visit and is able to provide informed consent prior to initiation of any study related procedures.
• At screening visit, subjects meet Diagnostic and Statistical Manual of Mental Disorders-fifth edition (DSM-5) criteria for single-episode major depressive disorder (MDD) or recurrent MDD, without psychotic features, based upon clinical assessment and confirmed by the Mini International Neuropsychiatric Interview (MINI).
• Subject is medically stable on basis of physical examination, medical history, vital signs (blood pressure, pulse rate, respiration rate, blood oxygen saturation, and temperature), clinical laboratory tests, and 12-lead ECG performed at screening visit, and/or prior to SC administration on Day 1. Subjects with abnormalities that are judged to be not clinically significant (NCS) at the discretion of the investigator may be included. This determination must be recorded in the subject's source documents and initialed by the investigator.
• At screening visit, subjects must have insufficient response to at least 2 oral AD treatments, at least one of which is in the current episode of depression. Massachusetts General Hospital Antidepressant Treatment Response Questionnaire (MGH-ATRQ) will be used to assess AD treatment response during the current episode; prior medication history (e.g., medical/pharmacy/prescription records or a letter from a treating physician, etc.) will be used to determine AD treatment response in prior episode(s). If the subject's current episode of depression is > 2 years, the upper limit of duration for assessing treatment response is applicable to only the last 2 years.
• Subject has a MADRS total score of ≥ 22 at screening.
• Male and female subjects of childbearing potential must be willing to use a reliable method of contraception (e.g., total abstinence, condom and spermicide, intrauterine device [IUD], oral contraception which has been stable for 30 days) during the entire trial and at least 4 months after stopping the investigational product.
• Female subjects of childbearing potential must have a negative serum β-human chorionic gonadotropin (β-hCG) at screening visit and a negative urine pregnancy test prior to SC administration on Day 1.
• Male and female subjects must agree not to donate sperm or eggs (ova, oocytes) during the study and for at least 3 months after receiving the investigational drug.
• Agree to adhere to the prohibitions and restrictions specified in this protocol.

You may not qualify if…

• Subject has a history of, or current signs and symptoms of, liver or renal insufficiency; significant cardiac, vascular, pulmonary, gastrointestinal, endocrine, neurologic, hematologic, rheumatologic, metabolic disturbances, or fibromyalgia.
• Subject has uncontrolled hypertension despite diet, exercise or a stable dose of a permitted anti-hypertensive treatment at screening visit, or prior to SC administration on Day 1 (defined as a supine SBP > 140 mmHg or DBP > 90 mmHg); or any past history of hypertensive crisis.
• Subject has aspartate aminotransferase (AST) or alanine aminotransferase (ALT) ≥ 2 × the upper limit of normal (ULN) or total bilirubin > 1.5 × ULN.
• Subjects with history of or current DSM-5 diagnosis of psychotic disorder, or MDD with psychotic features, post-traumatic stress disorder (PTSD), bipolar or related disorders (confirmed by MINI), obsessive compulsive disorder (current only), intellectual disability (DSM-5 diagnostic codes 317, 318.0, 318.1, 318.2, 315.8, and 319), autism spectrum disorder, borderline personality disorder, antisocial personality disorder, histrionic personality disorder, or narcissistic personality disorder.
• Subject has suicidal ideation with intent to act within 6 months prior to screening visit or Study Day 1 (predose) based on investigator's discretion or C-SSRS, or has a history of suicidal behavior within the past year as assessed on the C-SSRS; or subject has homicidal ideation/intent at screening visit or on Day 1.
• Subject had previously no treatment response to ketamine, S-ketamine, R-ketamine, all of the available AD treatment options in the double-blind phase (based on MGH-ATRQ), or an adequate course of electroconvulsive therapy (defined as at least 7 treatments with unilateral/bilateral electroconvulsive therapy [ECT]), in the current major depressive episode according to clinical judgment.
• Subject has a score of ≥ 5 on the STOP-Bang questionnaire, in which case obstructive sleep apnea must be ruled out (e.g., apnea-hypopnea index [AHI] must be < 30). A subject with obstructive sleep apnea can be included if he or she is using a positive airway pressure device or other treatment/therapy that is effectively treating (i.e., AHI < 30) his or her sleep apnea.
• Subjects who meet DSM-5 criteria for moderate or severe substance or alcohol use disorder, except for nicotine or caffeine, within 6 months prior to screening visit.
• Subjects with lifetime history of ketamine, phencyclidine (PCP), lysergic acid diethylamide (LSD), or 3,4-methylenedioxymethamphetamine (MDMA) hallucinogen-related disorder are exclusionary.
• Subjects with positive urine drug test result(s) at screening visit or predose on Day 1 for barbiturates, methadone, opiates, cocaine, phencyclidine (PCP), and amphetamine/methamphetamines will be excluded. A positive test result for cannabinoids predose on Day 1 is exclusionary.
• Subjects with positive alcohol breath test result at screening visit or predose on Day 1, or predose on Day 8.
• Subject has a history of malignancy within the 5 years prior to screening.
• Subject has known allergies, hypersensitivity, intolerance, or contraindication to ketamine, S-ketamine, R-ketamine, or excipients in the investigational drug.
• Subject has taken any prohibited therapies.
• Subjects have received an investigational drug, treatment of ketamine, S-ketamine, R-ketamine, vaccine, or used an invasive investigational medical device within 60 days before planned Study Day 1 or currently enrolled in an investigational study.
• Subjects are pregnant or lactating at screening visit or prior to the SC administration on Day 1 or planning to become pregnant during the study.
• Subject has any condition or situation/circumstance for which, in the opinion of the investigator, participation would not be in the best interest of the subject (e.g., compromise the well-being) or that could prevent, limit, or confound the protocol-specified assessments.
• Subject has had major surgery, (e.g., requiring general anesthesia) within 2 weeks before screening visit, or will not have fully recovered from surgery, or has surgery planned during the time the subject is expected to participate in the study.
• Subjects is an employee of the investigator or the trial site, with direct involvement in the proposed trial or other trials under the direction of the investigator or trial site, or is a family member of an employee or of the investigator.
• Subject has a history of human immunodeficiency virus (HIV), hepatitis B surface antigen (HBsAg) or hepatitis C antibody (anti-HCV) positive, or other clinically active liver disease, or tests positive for HIV, HBsAg, or anti-HCV at screening visit.
• Subject has CS ECG abnormalities at screening or predose on Day 1.
• Subject has received vagal nerve stimulation (VNS) or has received deep brain stimulation (DBS) in the current episode of depression.
• Subject has a current or past history of seizures (uncomplicated childhood febrile seizures with no sequelae are not exclusionary).
• Subject is taking a total daily dose of benzodiazepines greater than the equivalent of 6 mg/day of lorazepam at the start of the screening phase.
• Subjects with any underlying medical conditions where elevation of blood pressure may pose a risk (including severe cardiovascular disease, recent cerebral injury, increased intracranial pressure, intracranial bleeding, or acute stroke, unstable heart failure, untreated glaucoma) are excluded.
