Single-Dose Pharmacokinetics (PK) Study of Novel Neurogenic Compound NSI-189

The safety and scientific validity of this study is the responsibility of the study sponsor and investigators. Listing a study does not mean it has been evaluated by the U.S. Federal Government. Read our disclaimer for details.
ClinicalTrials.gov Identifier: NCT01310881
Recruitment Status : Completed

Brief Summary:
This is a subject single blinded, randomized, placebo-controlled, single dose, first-time-in-human study with three or more ascending cohorts.

Condition or disease Intervention/treatment Phase
Depression Drug: NSI-189 Phosphate Phase 1

Detailed Description:
Each subject will undergo Screening (Day -28 to Day -2). Subjects will return to the clinical site on Day -1, be admitted to the unit, and eligibility will be reconfirmed. Eligible subjects will receive a single dose of investigational medicinal product (IMP, NSI-189 Phosphate or Placebo) on Day 1 and will be followed for safety and PK until discharge on Day 3. Subjects who are experiencing any significant AEs that are considered possibly related to study drug will be kept at the unit for an additional day (or longer) until the event resolves or it is considered medically safe for the subject to be discharged. Subjects will have a telephone Follow-up on Day 4 and return to the unit on Day 7 (± 1) for End-of-study. Participation of an individual subject may last up to 36 days from the time of Screening until the End-of-study.

Primary Outcome Measures :
  1. Safety of drug assessed by number and severity of adverse events in drug vs placebo groups [ Time Frame: 7 days ]
    Values for vital signs, standard physical examination, ECG, EEG and standard clinical laboratory tests (haematology and biochemistry), and for standard neurological exam and the Columbia Suicide Severity Rating Scale will be compared between NS189 and placebo.

Secondary Outcome Measures :
  1. Pharmacokinetics of NS189 will be determined by plasma sample collection at various timepoints post-dosing, and measuring concentration of drug over time. [ Time Frame: 7 days ]
    Concentration of NS189 will be measured in plasma and standard PK values determined: AUC, Cmax, Tmax, T1/2, CL, Vz
