  Purpose

The purpose of this study is to investigate the effect of the rapidly acting intranasal insulin derivative (glulisine) on memory and cognition in 12 patients suffering from mild-moderate Alzheimer's Disease (AD) using a double-blind placebo-controlled single dose study. This study will further assess safety of insulin glulisine as well as the effects of this drug on olfaction.

Primary Outcome Measures:
  • cognitive performance [ Time Frame: 20 minutes post-intranasal administration ] [ Designated as safety issue: No ]
    Chance from post-saline to post-insulin glulisine for each of the following measures: RBANS,Digit Span, Boston Naming and Trail Making tests. The response to intranasal Insulin glulisine will be expressed as a percent change from post-saline [(result post-insulin - result post-saline) / ( results post-saline)] x 100%.


Secondary Outcome Measures:
  • olfactory function [ Time Frame: 60 minute post intranasal adminsitration ] [ Designated as safety issue: No ]
    Change from post-saline to post-insulin glulisine in immediate Sniff Magnitude Ratio (measured post-dose).

Detailed Description:

A single center, phase II randomized, double-blind, placebo-controlled, cross-over study designed to assess the efficacy and safety of intranasally (IN) delivered insulin glulisine versus placebo in patients aged 65-85 with mild-moderate Alzheimer's Disease (AD). Twelve AD subjects (six female and six male) will be randomized to receive a single dose of either 20 IU/IN insulin glulisine or placebo using the MAD 300 device.

  Eligibility

Ages Eligible for Study:   65 Years to 85 Years
Genders Eligible for Study:   Both
Accepts Healthy Volunteers:   No
Criteria

Inclusion Criteria:

  • Male or female subject with a clinical diagnosis of probable AD in accordance with NINCDS-ADRDA criteria and Dementia Rating Scale (McKhann 1984).
  • MMSE score of 18-26.
  • Hachinski Ischemia Score < 4.
  • Age is > 65 and <85 years
  • Females must be > 2 years post-menopausal or surgically sterile.
  • Must be able to speak, read and understand English in order to comply with testing of cognitive function, memory and physiology.
  • Must have a dedicated family member /caregiver, able to attend all visits and report on subject's status.
  • Subject and family member/caregiver have both provided fully informed written consent prior to participation. In the event that subject is legally unable to provide informed written consent due to deterioration in cognitive abilities, fully informed written consent must be provided by a legally authorized representative.
  • On a stable dose (≥ 1 months) of a prescribed acetylcholinesterase inhibitor (e.g. donepezil, rivastigmine, galantamine) and/or memantine.
  • A brain CT or MRI in the last 2 years compatible with the diagnosis of probable Alzheimer's Disease.
  • A CDR ranging from 1 to 2.

Exclusion Criteria:

  • Medical history and/or clinically determined evidence of other CNS disorders including brain tumor, active subdural hematoma, seizure disorder, multiple sclerosis dementia with Lewy bodies, vascular dementia, corticobasal syndrome, progressive supranuclear palsy, Parkinson's disease, multiple system atrophy, frontotemporal dementia, normal pressure hydrocephalus, Huntington's disease, or Jakob-Creutzfeldt disease presenting as dementia.
  • Personal medical history and/or clinically determined disorders: current B12 deficiency, positive syphilis serology, chronic sinusitis or any untreated thyroid disease, significant head trauma, or history of difficulty with smell and/or taste prior to AD diagnosis.
  • Diagnosis with any form of diabetes mellitus, actively takes insulin, or has HbA1c > 6.1 % at screening.
  • Personal history of any of the following: moderate to severe pulmonary disease, congestive heart failure, significant cardiovascular and/or cerebrovascular events in previous 6 months, condition known to affect absorption, distribution, metabolism, or excretion of drugs such as any hepatic, renal or gastrointestinal disease or any other clinically relevant abnormality that inclusion would pose a safety risk to the subject as determined by Investigator.
  • Heavy smoker (defined as smoking half a pack or more per day in the last 10 years prior to entry in the study).
  • Personal history of any psychiatric illness, except major depressive disorder (according to DSM-IV TR) currently in remission or stable with treatment for > 2 years, or any other psychiatric condition that inclusion would pose a safety risk to the subject as determined by Investigator. Patients with active depression (Geriatric Depression Score>9) are excluded from the study.
  • Currently taking any medications, herbals and food supplements that are determined by Investigator to interfere with procedural testing of cognitive function as well as ensure study safety.
  • Recent change (< 1 months) in prescribed acetylcholinesterase inhibitor (e.g. donepezil, rivastigmine, galantamine) or memantine.
  • Current or recent drug or alcohol abuse or dependence defined by DSM-IV TR.
  • Systolic blood pressure > 160 or < 90 mmHg or diastolic blood pressure > 100 or < 60 mmHg at Screening.
  • Screening laboratory results that are medically relevant and which would pose a safety risk to the subject as determined by Investigator.
  • Participation in any other research study at least 3 months prior to this study.
  • Insulin allergy.
  • History of significant traumatic brain injury
  • History of acute and chronic rhinitis and/or sinusitis.
  • Legally unable to provide informed written consent due to deterioration in cognitive abilities.
