We wanted to examine tolerability and efficacy of NSI-189, a benzylpiperizine-aminiopyridine neurogenic compound for treating major depressive disorder (MDD). This was a Phase 1B, double blind, randomized, placebo controlled, multiple-dose study with three cohorts. The first cohort received 40 mg q.d. (n=6) or placebo (n=2), the second cohort 40 mg b.i.d. (n=6) or placebo (n=2), and the third cohort 40 mg t.i.d. (n=6) or placebo (n=2). Twenty-four patients with MDD were recruited, with the diagnosis and severity confirmed through remote interviews. Eligible patients received NSI-189 or placebo for 28 days in an inpatient setting with assessments for safety, pharmacokinetics (PK) and efficacy. Outpatient follow-up visits were conducted until day 84 (±3). NSI-189 was relatively well tolerated at all doses, with no serious adverse effects. NSI-189 area under the curve increased in a dose-related and nearly proportional manner across the three cohorts, with a half-life of 17.4–20.5 h. The exploratory efficacy measurements, including Symptoms Of Depression Questionnaire (SDQ), Montgomery-Asberg Depression Scale (MADRS), Clinical Global Impressions—Improvement (CGI-I), and The Massachusetts General Hospital (MGH) Cognitive and Physical Functioning Questionnaire (CPFQ) showed a promising reduction in depressive and cognitive symptoms across all measures for NSI-189, with significant improvement in the SDQ and CPFQ, and a medium to large effect size for all measures. These improvements persisted during the follow-up phase. In summary, NSI-189 shows potential as a treatment for MDD in an early phase study. The main limitation of this preliminary study was the small sample size of each cohort.Molecular Psychiatry advance online publication, 8 December 2015; doi:10.1038/mp.2015.178. © 2015 Macmillan Publishers Limited Source

Although it is known that certain benzylpiperazine-aminopyridines or open chain forms thereof are effective in stimulating neural growth in in vitro tests, it has now been surprisingly found that administering these compounds in a dosage range of 10 mg/day-130 mg/day over 25-35 days is effective in treating Major Depressive Disorder (MDD) such that statistically significant results can be obtained with samples of only six subjects.

The invention relates generally to methods of treating spasticity, rigidity, or muscular hyperactivity conditions by introducing a portion of an expanded population of neural stem cells into an area of a recipient spinal cord.

The present disclosure provides a human neural stem cell comprising an exogenous polynucleotide coding for a growth factor such as IGF-1. Also disclosed are methods of using the human neural stem cells for the treatment of neurodegenerative diseases or disorders including, for example, ALS.
