Study Details

Study Description

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.

Condition or Disease	Intervention/Treatment	Phase
Major Depressive Disorder	Drug: 80 Milligrams NSI-189 Drug: Placebo Drug: 40 Milligrams NSI-189	Phase 2

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.

Inclusion Criteria:

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.

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.

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).
