About this study

Official title: Evaluating the Efficacy of Controlled Pulsatile Intravenous Insulin on Cognition and Amyloid Burden in Patients With Alzheimer's Disease- A Pilot Study

The objectives of this project are to examine amyloid burden and cognition in a group of subjects diagnosed with Alzheimer's Disease (AD) or Mild Cognitive Impairment (MCI) before and after a six month course of insulin delivered weekly in a controlled pulsatile intravenous fashion in a clinical setting. The investigators central hypothesis is straightforward: The investigators predict that controlled pulsed IV infusion of insulin will improve cognition in patients with AD, and that this improvement will be correlated with a decrease in amyloid burden in these patients.

Read the detailed description

Visit 1: Consent/Assent will be obtained before any study related procedures are performed. Once consent is obtained subjects will be assessed to determine eligibility based on study inclusion/exclusion criteria. A history and physical with possible neurological examination will be conducted. Cognitive impairment will be assessed by having the subject complete the Folstein Mini-Mental State Exam (MMSE).

Qualifying subjects who wish to participate in the study will be scheduled to return for a study orientation visit. Subjects are required to have a study partner. Subjects will be given a copy of the study partner informed consent form (ICF) to take home with them. A potential study partner(s) must attend the orientation visit with the subject.

Visit 2: Study Orientation: ICF will be obtained from subject study partner(s). Subjects and their study partner(s) will be given information about what is required for the study. They will be given the patient logs that are to be kept at home between sessions and discussed with study staff at the following session. Subjects and study partners will be trained to become proficient in checking their blood sugar with one of the common blood glucose meters as well as how to use a supply of glucose which can cover any potential hypoglycemic reaction. Subjects and/or their study partners will be oriented to the location where the controlled pulsatile IV insulin infusion therapy will be performed. They will be instructed on where to park and where to go when they arrive.

Visit 3: Pre-Therapy Amyloid PET scan

Visits 4 - 28: Insulin Therapy Visits: Subjects will complete 25 insulin therapy sessions which will occur on a weekly basis, over 6 months. Prior to insulin treatment the following assessments will be completed: MMSE, CDT, QOLS, and CGI. Also prior to insulin therapy, as well as between insulin therapy treatments, basal O2 and C O2 measurements will be obtained.

Pre labs will be collected at visit 4, mid labs at visit 16, and post labs at visit 28.

Visit 29: Post-therapy Amyloid PET Scan

Visit 30: The final study visit will be conducted in the Psychopharmacology Research Clinic within one month of the subject completing the last insulin treatment.

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • Insulin LISPRODrug

    Also called Humalog

    Insulin is delivered in a pulsatile fashion. One treatment is approximately 10-15 units of insulin (exact dose based on weight) split into ten pulses delivered over one hour. Three treatments will be administered per session with one session per week for six month duration.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. cerebral glucose metabolism

    Cerebral glucose metabolism will be measured using pre and post FDG PET Scans.

    Measured: 25 weeks

  2. cognition

    Changes in cognition will be measured before therapy, on a weekly basis during therapy, and after therapy using the Folstein Mini-Mental State Exam (MMSE) and the Clock Drawing Test (CDT).

    Measured: 30 weeks

Secondary outcomes (2)
  1. general clinical improvement

    Changes in general clinical improvement will be measured before therapy, on a weekly basis during therapy, and after therapy using the Clinical Global Impression (CGI) and the Quality of Life Scale (QOLS).

    Measured: 30 weeks

  2. basal metabolism

    Changes in basal metabolism will be measured before therapy, during weekly treatment sessions, and after therapy using measured O2 and CO2 levels.

    Measured: 30 weeks

Questions about this trial

What is this clinical trial studying?

A study testing Insulin LISPRO in people with Alzheimer's Disease and Mild Cognitive Impairment, run by Louisiana State University Health Sciences Center Shreveport at 1 site in United States.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 7 inclusion and 3 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: withdrawn, as of the sponsor's last update on 13 Mar 2014. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in United States. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

Are results available for this study?

The study was withdrawn before enrolling participants, so there are no results.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

cerebral glucose metabolism (time frame: 25 weeks). The study lists 2 primary outcomes in all. It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 13 Mar 2014.
