Brief Summary:
The purpose of this study is to find out if different doses of Investigational Drug are safe, tolerable, and if they have an effect on Mild Cognitive Impairment (MCI).

Condition or disease Intervention/treatment Phase
Mild Cognitive Impairment, So Stated Drug: AL-108 Drug: Placebo Phase 2

Detailed Description:

Pre-Clinical experiments indicate the AL-108 compound has neuroprotective, cognitive protective and neurotrophic properties; therefore, the compound could be tested in a variety of human diseases. Human diseases include Cognitive impairment associated with aging or neurodegenerative diseases such as Alzheimer's Disease.

This clinical trial aims at providing the dose rationale as well as safety and tolerability information for AL-108 as evaluated after 12 weeks of intranasal administration in subjects with Mild Cognitive Impairment (MCI).

There are currently no drugs approved for the treatment of MCI nor accepted treatment or standard treatment approach.

  • Untreated sleep apnea or treatment for sleep apnea for <3 months.
  • Abnormal clinical laboratory test results, specifically: Alanine transaminase (ALT) or aspartate transaminase (AST) >2 х the upper limit of normal (ULN),Hematology <80% the lower limit of normal, Creatinine ≥2 mg/dL and ,Other clinical laboratory values or vital signs considered clinically significant in the opinion of the Investigator.
  • Treatment with any investigational drug, biologic, or device within the previous 30 days prior to screening.
  • Surgery involving general anesthesia within the past 3 months or planned surgery requiring general anesthesia during the study period.
