Phase1a, Dose-escalation Study of NNI-362 in Healthy Aged Volunteers

The purpose of this study is to examine the safety, tolerability and pharmacokinetics of single and multiple doses of NNI-362 in healthy aged population.

The early clinical development strategy consists of the initial evaluation of safety and tolerability of NNI-362. This FIH Phase I includes single and multiple ascending dose studies in healthy aged volunteers. Assessment of suicidal ideation/behavior will be performed at baseline and at all study visits and on days of inpatient confinement in conformance with FDA recommendations.

Eligibility Criteria:
Inclusion Criteria:

* Healthy aged volunteers of either sex between the ages of 50 and 72 inclusive at time of screening.

  * Subjects must be in reasonably good health as determined by investigator based on medical history, vital signs measurements, physical examination, screening laboratory results and ECG.
  * Normal age-related findings as well as well-controlled, chronic and stable medical conditions (e.g., hypertension, osteoarthritis, non-insulin dependent diabetes mellitus, osteoporosis, gout, Paget's disease, hypothyroidism) will not be exclusionary if they are not expected to compromise subject safety, study conduct, or study objectives.
  * Non-interacting medications for stable allowable medical conditions will be allowed following review and approval by the medical monitor.
  * An adequate understanding of the requirements of the study, provision of written informed consent, and agreement to abide by the study restrictions.
  * Negative urine screen for drugs of abuse within 24 h before the administration of the first dose of study drug and in the multiple dose study upon readmission to the clinical unit from outpatient status.
