  • Incidence and severity of four-item positive symptom subscale of the Brief Psychiatric Rating Scale (BPRS+)

    The Brief Psychiatric Rating Scale (BPRS) is an 18-item rating scale which is used to assess potential treatment-emergent psychotic symptoms. The scores range from 0 (not assessed) to 7 (extremely severe). The higher score represents a worse outcome. Only the four-item positive symptom subscale (BPRS+) will be used in the study to assess treatment-emergent psychotic symptoms. BPRS+ consists of suspiciousness, hallucinations, unusual thought content, and conceptual disorganization.

    Baseline (prior to dosing) and through the End of Study (Day 36)/Early termination

  • Injection site tolerability based on injection site grading scale

    Injection site grading scale consists of 5 items including assessment on pain, tenderness, induration, erythema/redness, and swelling. Each item will be scaled from Grade 0 (None) to Grade 4 (potentially life threatening). The evaluation will be performed by the investigator or trained designee who will be a qualified healthcare professional.

    At the time of injection and through the End of Study (Day 36)/Early termination or Follow up visit

    Injection site pain will be assessed by the subject with a 100 mm VAS scale ranging from 0 to 100, where 0 represents "no pain" and 100 represents "maximum pain". The evaluation will be performed by the investigator or trained designee who will be a qualified healthcare professional.

    At the time of injection and through the End of Study (Day 36)/Early termination or Follow up visit

  • Injection site tolerability based on injection site evaluation for potential reactions and evidence of removal

    The local injection site will be evaluated for potential reactions and evidence of removal. The evaluation will be performed by the investigator or trained designee who will be a qualified healthcare professional.

Eligibility Criteria

Age18 Years - 65 Years
Sexall
Healthy VolunteersNo
Age GroupsAdult (18-64), Older Adult (65+)

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 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.
