About this study

The purpose of this study is to evaluate the safety and efficacy of NIC5-15in the treatment of Alzheimer's Disease.

Read the detailed description

Recent epidemiologic evidence, has suggested that diabetes mellitus significantly increases risk for the development of Alzheimer's disease, independent of vascular risk factors. Moreover, even patients who are simply insulin resistant, without frank diabetes, have been shown to share this elevated risk for the development of AD. As insulin's role as a neuromodulator in the brain has been revealed, several potential mechanisms for the interaction of diabetes or insulin resistance with AD have been suggested such as decreased cortical glucose utilization particularly in the hippocampus and entorhinal cortex; increased oxidative stress through the formation of advanced glycation end products; increased Tau phosphorylation and neurofibrillary tangle formation; and increased beta-amyloid aggregation through inhibition of insulin-degrading enzyme. The future treatment of AD might involve pharmacologic and dietary manipulations of insulin and glucose regulation

NIC5-15 is a single, small, naturally occurring molecule. Animal studies and some human trials have shown NIC5-15 to be safe and a potent insulin sensitizer at doses equivalent to 800-2000mg per day. In preclinical studies at doses higher than those previously studied in clinical trials, we found that NIC5-15 interferes with the accumulation of beta amyloid, an important step in the development of Alzheimer's pathology. These data suggest that NIC5-15 may be a reasonable therapeutic agent for the treatment of Alzheimer Disease for two reasons:

  1. It is a -secretase inhibitor that is Notch-sparing.
  2. It is potentially an insulin-sensitizer.

However critical safety and human efficacy studies must be conducted. This application proposes to conduct these early critical human studies. The goal of the studies contained in this proposal is to establish safety and efficacy of NIC5-15 for the treatment of AD. The specific objectives of this study are to:

Specific Objective #1) Conduct a multiple dose safety study of NIC5-15 to establish safety in the doses that appear to block amyloid accumulation. These studies will characterize the safety profile, pharmacokinetics, and tolerability

Specific Objective #2) Conduct a double blind placebo controlled pilot efficacy study of NIC5-15 in patients with AD. The goals of this study are to:

  1. Demonstrate feasibility for a multi-site trial that will be used to guide the design of a future larger effort. Demonstration of feasibility will include examination of accrual rate, overall recruitment, adherence to protocol, compliance with medication and willingness to complete a randomized trial, and lack of short term toxicity.
  2. Collect preliminary evidence of efficacy in terms of cognitive and global measures as well as secondary efficacy outcomes of activities of daily living, behavioral disturbances and AD biomarkers.

What is being measured

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

  1. Safety Assessments: Number of Participants With Adverse Events

    vital signs, physical exam, Symptom Checklist, complete blood count, serum chemistries, urinalysis, and electrocardiogram

    Measured: Safety Labs, Physical Exams: 6 times over 7 weeks. Adverse Events assessed 21 times over the course of 7 weeks

Secondary outcomes (1)
  1. Changes From Baseline in Clinical Measures of Cognition at Terminal Visit

    Mini-Mental Status Exam (MMSE) 0(worst)-30(best); ADAS-cog 0 (best cognitive performance across multiple domains) - 70(worst); Activities of Daily Living (ADCS-ADL) 0(least capable of function in daily and instrumental activities)-54(best)

    Measured: baseline and six weeks

Questions about this trial

What is this clinical trial studying?

A Phase 2 study testing NIC5-15 in people with Alzheimer Disease and Dementia, run by VA Office of Research and Development 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 11 inclusion and 11 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: finished, as of the sponsor's last update on 9 Jan 2017. 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. Some participants in this study may receive a placebo. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

What does this phase mean?

Phase 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

Are results available for this study?

Yes. Results are posted in the registry (first posted 9 Jan 2017). A summary is in the For doctors view, and the full results are on ClinicalTrials.gov.

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?

Safety Assessments: Number of Participants With Adverse Events (time frame: Safety Labs, Physical Exams: 6 times over 7 weeks. Adverse Events assessed 21 times over the course of 7 weeks). 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 9 Jan 2017.
