Study of NSI-189 for Major Depressive Disorder

Status unconfirmed · Phase 2 · Has a placebo group

Conditions studied: Major Depressive Disorder

In brief

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.

You may qualify if…

• Subject has the ability to understand the purpose, potential benefits and risks of the study and to provide signed and dated informed consent, authorizing the use of protected health information in accordance with national and local Subject privacy regulations.
• Males and females 18 to 60 years of age, inclusive, at the time of informed consent.
• 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).

You may not qualify if…

• 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.
• Clinically significant (as determined by the Investigator) 12-lead Electrocardiogram (ECG) abnormalities, including corrected QT interval using Bazett's correction method of >450 msec for males and >470 msec for females.
• Subjects with (current) severe Post-Traumatic Stress Disorder (PTSD), severe Obsessive Compulsive Disorder (OCD), severe binge eating disorder, or subjects with anorexia or bulimia nervosa active within the past three years.
• Subjects who plan to undergo elective invasive procedures/surgeries at any time during the study through End-of-study.
• Subjects taking excluded medications (See Appendix 1)..
• History of alcohol or drug-dependence or abuse by 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 within 12 months prior to Screening.
• Positive screening test or baseline test for drugs-of-abuse (cocaine, amphetamines, barbiturates, opiates, benzodiazepines, cannabinoids, phencyclidine). Note any positive test result(s) for benzodiazepine(s), opiates, or psychostimulants accompanied by confirmation of a prescription for a valid medical reason will be allowed.
• Positive serum β-human chorionic gonadotropin (β-HCG) test at Screening or positive urine pregnancy test at baseline that is consistent with pregnancy (females only).
• Donation or loss of whole blood >200 mL within 30 days prior to dosing or ≥500 mL within 56 days prior to dosing. Note: Blood taken for routine medical evaluations totaling less than 50 mL will be permitted.
• Females who are pregnant, lactating, or planning to become pregnant during the study.
