April 8, 2020 updated by: HealthPartners Institute

A Phase II, Single Center, Randomized, Double-Blind, Placebo-Controlled Study of the Safety and the Therapeutic Effectiveness of Intranasal Glulisine in Amnestic Mild Cognitive Impairment and Probable Mild Alzheimer's Disease

This study evaluates the safety and effectiveness of intranasal (IN) glulisine in patients with amnestic mild cognitive impairment (aMCI) and probable Alzheimer's disease. Half of participants will receive IN glulisine, while the other half will receive IN placebo.

Detailed Description

Disruption of central nervous system (CNS) insulin signaling has been increasingly associated with Alzheimer's Disease pathogenesis, and consequently this disease has been referred to as a type III diabetes of the brain. Clinical trials of intranasal insulin in AD have demonstrated therapeutic effects of intranasal (IN) insulin in memory-impaired adults in terms of memory recall without significantly altering serum insulin or glucose levels. In this study, the investigators are investigating the chronic effects of the rapid acting insulin, glulisine, administered intranasally (IN) 20 IU two times daily in adults with amnestic-mild cognitive impairment (a-MCI) and mild Alzheimer's disease (AD). The investigation will enroll n=90 subjects and follow them over a 6 month period.

This study has the following objectives:

  1. Primary:

    a. To measure the chronic effects of IN insulin glulisine on cognition and function in subjects with aMCI and probable mild AD over a 6 month period.

  2. Secondary:

    1. To measure the effect of IN insulin glulisine on mood in subjects with aMCI and mild AD over a 6 month period.
    2. To measure the safety and efficacy of IN glulisine in aMCI and mild AD subjects with non-insulin dependent diabetes over a 6 month period.

  3. Exploratory:

    1. To measure the effect of IN delivery of insulin glulisine on parieto-temporal and posterior cingulate/precuneus glucose metabolism in subjects with aMCI and mild AD over a 6 month period.
    2. To measure the chronic effect of IN delivery of insulin glulisine on AD-specific cerebrospinal (CSF) biomarkers (Abeta42, tau, and phospho-tau) in subjects with aMCI and mild AD over a 6 month period.

Description

Inclusion Criteria:

Subject is/has

  • clinical and research diagnosis of amnestic-MCI OR probable mild AD in accordance with National Institute of Neurological and Communicative Disorders and Stroke and the Alzheimer's Disease and Related Disorders Association (NINCDS-ADRDA) criteria
  • Montreal Cognitive Assessment (MoCA) score 18-27
  • Hachinski Ischemia Score <4
  • 50-90 years of age
  • Females at least 2 years post-menopausal or surgically sterile
  • Proficiency in speaking, reading and understanding English
  • Dedicated family member /caregiver, who will be able to attend all visits and report on subject's status
  • (and family member/caregiver) 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
  • If AD, a brain computed tomography (CT) or magnetic resonance imaging (MRI) in the initial diagnostic workup or subsequent care that is compatible with the diagnosis of probable AD

Exclusion Criteria:

Subject has/have/is

  • medical history and/or clinically determined evidence of other central nervous system (CNS) disorders including, but not limited to 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
  • medical history and/or clinically determined disorders: current B12 deficiency, chronic sinusitis, any untreated thyroid disease, significant head trauma and history of difficulty with smell and/or taste prior to AD diagnosis
  • history of any of the following: moderate to severe pulmonary disease, poorly controlled congestive heart failure, significant cardiovascular and/or cerebrovascular events within 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
  • previous nasal and/or oto-pharyngeal surgery and severe deviated septum and/or other anomalies
  • history of any psychiatric illness, with the exception of major depressive and anxiety disorder (according to Diagnostic and Statistical Manual of Mental Disorders, version 5, Text Revision (DSM-IV TR)) currently in remission or stable with treatment for > 2 yrs, or any other psychiatric condition that inclusion would pose a safety risk to the subject as determined by investigator
  • currently taking any medications, herbals and food supplements that are medically/clinically contraindicated as determined by investigator in order to comply with procedural testing of cognitive function as well as ensure study safety. See list of prohibited medications and compounds
  • undergone a recent change (<1mo) in their prescribed acetylcholinesterase inhibitor (e.g. donepezil, rivastigmine, galantamine) or memantine.
  • undergone a recent change (<1mo) in their selective serotonin re-uptake inhibitor (SSRI) or anti-depressant medication
  • current or recent drug or alcohol abuse or dependence as defined by DSM-IV TR
  • laboratory results that are medically relevant, in which inclusion would pose a safety risk to the subject as determined by investigator
  • participated in any other research study at least 3 mos prior to this study
  • an insulin allergy

What is the study measuring?

Primary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Change in Cognition as Measured by the Alzheimer's Disease Assessment Scale - Cognitive 13 (ADAS-Cog 13)
Time Frame: Baseline and 6 months
The ADAS-Cog was developed as an outcome measure for global cognition in clinical trials for Alzheimer's disease. The ADAS-Cog assesses multiple cognitive domains including memory, language, praxis, and orientation. The modified ADAS-Cog 13-item scale includes all original ADAS-Cog items with the addition of a number cancellation task and a delayed free recall task, for a total of 85 points (0: no cognitive impairment; 85: severe impairment).
Baseline and 6 months
Change in Functional Performance as Measured by the Clinical Dementia Rating (CDR) Scale
Time Frame: Baseline and 6 months
The CDR is a 5-point scale used to characterize six domains of cognitive and functional performance applicable to Alzheimer disease and related dementias: Memory, Orientation, Judgment & Problem Solving, Community Affairs, Home & Hobbies, and Personal Care. Possible scores on the CDR are 0 (no impairment), 0.5 (very mild), 1 (mild), 2 (moderate), and 3 (severe). The total CDR ratings for each of the six cognitive/functional domains can be added to create a CDR sum of boxes (SOB). The overall SOB score ranges from 0 to 18; with 18 indicating severe impairment and 0 indicating no impairment.
Baseline and 6 months
Change in Functional Performance as Measured by the Functional Activities Questionnaire (FAQ)
Time Frame: Baseline and 6 months
The FAQ measures instrumental activities of daily living (IADLs), such as preparing balanced meals and managing personal finances. The FAQ is a sum of scores ranging from 0 (normal) to 30 (complete dependence on others).
Baseline and 6 months
