About this study

Official title: A Longitudinal Observational Cohort Study of NSI-189, a Neurogenic Compound Among Out-Patients With Major Depressive Disorder

All subjects completing the randomized treatment period in Protocol NS2014-1 will discontinue study drug and be asked to provide consent to be followed in this 6-month study, at their final safety visit. The study will consist of an enrollment visit, followed by bi-monthly in-clinic visits with monthly telephone visits between in-clinic visits.

Read the detailed description

Following completion of the NS2014-1 final study visit procedures, Subjects will be offered the opportunity to enroll in this longitudinal observational cohort protocol to monitor their depression and to assess durability of effect and long-term safety of NSI-189.

The Enrollment Visit begins when informed consent is signed.The duration of the follow-up period will be up to 6 months, until the start of a new antidepressant treatment. Subjects who provide consent will be seen for in-person visits every 8 weeks, with bi-monthly phone visits occurring between in-person visits. Safety assessments and efficacy assessments will be performed at each visit. No study drug will be taken during the Longitudinal Observational Cohort study.

Receives: Drug: NSI-189

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Primary Objective: Durability of Effect defined as the time until the start of a new antidepressant treatment (ADT)

    The primary objective is to determine the durability of effect of NSI-189 phosphate compared to placebo in subjects with Major Depressive Disorder as defined by the Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition (DSM 5TH EDITION). Durability of effect is defined as the time until the start of a new antidepressant treatment (ADT).

    Measured: 6 months

Secondary outcomes (9)
  1. Montgomery-Asberg Depression Rating Scale (MADRS)

    Compare the continued Montgomery-Asberg Depression Rating Scale (MADRS) response and remission rates of subjects treated with NSI-189 to those of subjects assigned to placebo. Response is defined as a 50% or greater reduction from baseline to endpoint on the Montgomery-Asberg Depression Rating Scale (MADRS) total score. Remission is defined as an endpoint MADRS total score of 10. The duration of 50% or greater reduction in Montgomery-Asberg Depression Rating Scale (MADRS) total score sustained following treatment will be noted.

    Measured: 6 months

  2. Quick Inventory of Depressive Symptomatology - Self-Rated (QIDS-SR)

    Compare the continued antidepressant efficacy of NSI-189 with that of placebo.

    Measured: 6 months

  3. Massachusetts General Hospital Cognitive and Physical Functioning Questionnaire (MGH CPFQ)

    Evaluate the continued efficacy of NSI-189 compared to placebo on the cognitive aspects associated with Major Depressive Disorder, and the onset and duration of improvement.

    Measured: 6 months

  4. Cogscreen Battery

    Evaluate the continued efficacy of NSI-189 compared to placebo on the cognitive aspects associated with Major Depressive Disorder, and the onset and duration of improvement.

    Measured: 6 months

  5. Symptoms of Depression Questionnaire (SDQ)

    Compare the continued efficacy of NSI-189 with that of placebo, as measured by the Symptoms of Depression Questionnaire (SDQ)

    Measured: 6 months

  6. Massachusetts General Hospital Sexual Functioning Inventory (MGH SFI)

    Characterize the safety and tolerability of NSI-189, compared to placebo.

    Measured: 6 months

  7. The Columbia Suicide Severity Rating Scale (C-SSRS)

    Characterize the safety and tolerability of NSI-189, compared to placebo.

    Measured: 6 months

  8. 17-item Hamilton Depression Rating Scale (HAMD17)

    HAMD17 will be used to characterize the safety and tolerability of NSI-189, compared to placebo.

    Measured: 6 months

  9. Discontinuation rates

    Characterize the safety and tolerability of NSI-189, compared to placebo.

    Measured: 6 months

Questions about this trial

What is this clinical trial studying?

An observational study of Major Depressive Disorder, run by Neuralstem Inc. at 12 sites in United States.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 2 inclusion and 3 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

How can a doctor refer a patient or contact the research team?

Contact Karl Johe, Ph.D. (NSI-189MDD@neuralstem.com), or a site near the patient. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Primary Objective: Durability of Effect defined as the time until the start of a new antidepressant treatment (ADT) (time frame: 6 months). It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT02724735, which also lists 1 linked publication.

Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 21 Sep 2016.
