Overview

Brief Summary

The study will consist of a screening period and a randomized treatment. Approximately 220 subjects who meet eligibility during the screening period will be randomized to initiate a 12-week, double-blind treatment with NSI-189 80 milligrams/day (provided as 40 milligrams twice per day), NSI-189 40 milligrams once a day, or placebo.

Detailed Description

The screening period will range from a minimum of 14 days to a maximum of 28 days. The Investigators will determine that the subjects meet eligibility criteria and will collect the demographic and medical data permitting full characterization of the subject. The duration of the randomization period will be 12 weeks. Subjects who meet inclusion/exclusion criteria at the Baseline Visit will be randomized to NSI-189 80 milligrams/day, given as 40 milligrams twice per day, NSI-189 40 milligrams/day, given once a day, or placebo. The treatment will be double-blinded.

  • Diagnosis of major depressive disorder, recurrent, as per Diagnostic and Statistical Manual of Mental Disorders, 5th edition criteria and confirmed by Structured Clinical Interview for the Diagnostic and Statistical Manual specific for Clinical Trials. Their major depressive episode must be at least 8 weeks in duration and confirmed via Structured Clinical Interview for the Diagnostic and Statistical Manual mood module interview administered by a remote, independent raters, prior to the baseline visit.
  • Montgomery-Asberg Depression Scale (MADRS) score of 20 or greater, at Screening and Baseline (MADRS score confirmed to be 20 or greater via remote SAFER interview by an independent rater prior to the baseline visit).
  • The following applies to female Subjects: Non-pregnant, non-lactating females of childbearing potential are eligible as long as they agree to use a double barrier method of birth control from Screening until 3 months following discontinuation of IP. Women who are not of childbearing potential (bilateral oophorectomy, bilateral tubal ligation, hysterectomy, or post-menopausal for at least 1 year) will not require such parameters in order to be eligible.
  • The following applies to male subjects: Male subjects with a female partner of childbearing potential will be required to use double barrier method of birth control or practice abstinence during this study and for 3 months following discontinuation of Investigational Product. Note: These requirements also apply for male subjects who have had a vasectomy.
  • Body mass index (BMI) ≥19.5 and ≤38.0 kg/m2, at Screening. Bodyweight must be \>50 kg.
  • Of stable medical health, in the opinion of the Site Investigator, as determined by Investigator discretion (medical history, physical examination, vital signs, ECG, and clinical laboratory assessments).

Exclusion Criteria

  • Clinically significant history or evidence of cardiovascular, respiratory, hepatic, renal, gastrointestinal, endocrine, neurological, immunological, or other major disease as determined by the Investigator or designee such that participation in the study would place subjects at increased risk for serious adverse events.
  • History of cancer or malignancy within the last 5 years. Note: Subjects with basal or squamous cell carcinoma may be permitted into the study on a case by case basis.
  • History of seizures; head trauma; or any clinically significant finding on the neurologic examination such that participation in the study would place subjects at increased risk for serious adverse events.
  • Previous or current diagnosis of bipolar or schizoaffective disorder or psychotic disorder, or any psychotic symptoms during the current major depressive episode (according to Diagnostic and Statistical Manual of Mental Disorders, 5th edition).
  • Subjects who have a concurrent primary psychiatric diagnosis, diagnosed by Structured Clinical Interview for Diagnostic and Statistical Manual of Mental Disorders, 5th edition, other than depression.
  • Subjects with delirium, dementia, Parkinson's disease, or Huntington's disease.
  • Subjects who have failed to respond to more than two antidepressant trials of adequate dose (as defined in Massachusetts General Hospital Antidepressant Treatment Response) and duration (at least 8 weeks in duration) during the current major depressive episode as determined by the local rater and confirmed by an independent, remote rater prior to the baseline visit.
  • Subjects with clinically significant suicidal ideation and/or behavior currently as determined by the Site Investigator, such that participation in the study would place subjects at increased risk for serious adverse events.
  • Subjects with any current homicidal ideation.
  • Clinically significant abnormal clinical chemistry values, as determined by the Site Investigator, or any values for Alanine aminotransferase (ALT), Aspartate aminotransferase (AST), total bilirubin or creatinine that are 1.5 times above the upper limit of normal (ULN) and deemed clinically significant by the Site Investigator; any clinically significant values as determined by the Site Investigator for platelets or hemoglobin that are below the lower limit of normal (LLN); or any out of normal range values for white blood cells (WBC) deemed clinically significant by the Site Investigator.
