Trial summary

Parkinson disease (PD) and multiple system atrophy (MSA) are progressive neurodegenerative disorders characterized by abnormal accumulation of α-synuclein. There is no effective treatment that can slow down the disease progression and both disorders are associated with severe cognitive decline. Read more about this study

About this study

Official title: A Double-blinded Placebo-controlled Single-center Study to Evaluate the Efficacy of Intranasal Insulin 40 International Units Day as Treatment for Subjects With Parkinson Disease and Multiple System Atrophy

Parkinson disease (PD) and multiple system atrophy (MSA) are progressive neurodegenerative disorders characterized by abnormal accumulation of α-synuclein. There is no effective treatment that can slow down the disease progression and both disorders are associated with severe cognitive decline. It was shown that intranasal insulin (INI) improves learning and memory in healthy and cognitively impaired non-diabetic adults.

The proof-of-concept, randomized, placebo-controlled, cross-over pilot study ( NCT01206322) has shown that a single 40 international units dose of intranasal insulin improves visuospatial memory in diabetes and control subjects.

This proposal includes randomized, double blinded, placebo-controlled trial of intranasal insulin (40 international units daily) in treatment of PD and MSA.

The study will evaluate 22 patients with PD and 22 patients with MSA. Total duration of the study will be 2 years. The primary goal is to assess the efficacy of INI in treatment of cognitive abnormalities in both PD and MSA. The primary efficacy end point will be change of the cognitive scale ratings.

What is being measured

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

  1. Change in Verbal Fluency FAS (F, A or S Words) Total Score

    Changes in Verbal Fluency FAS (a total number of F, A or S words) generated after 4 weeks of treatment compared to baseline, FAS total score is a sum of F,A, and S raw scores. The verbal fluency FAS test is used to assess phonemic fluency and verbal memory. Participants are asked to name words starting with letters F, A and S over one minute interval. The unit is a on scale, the normative data are adjusted for age and sex. The higher score means better verbal fluency.

    Measured: Baseline and post-treatment

Secondary outcomes (3)
  1. Modified Hoehn and Yahr Scale

    The modified Hoehn and Yahr Scale (HY) is used to assess severity of Parkinson Disease and treatment response post treatment as compared to baseline. The scale ranges from 1 to 5. The lower score indicates better outcome, e.g. less severe parkinsonism.

    Measured: Baseline and post-treatment

  2. Cognitive Impairment Using Montreal Cognitive Assessment (MoCA)

    The Montreal Cognitive Assessment (MoCA) is a one-page 30-point test administered in approximately 10 minutes and is used to assess symptoms of cognitive impairment and their changes after treatment as compared to baseline. MoCA scores range between 0 and 30 with higher scores indicative of better cognitive performance. A score of 26 and above is considered to be normal.

    Measured: Baseline and post-treatment

  3. Beck Depression Inventory Score (BDI)

    Beck Depression Inventory (BDI) is a 21-items self reported inventory with a scale evaluating depressive symptoms and the changes in BDI after treatment compared to baseline. The range of scores is 0 to 63, with higher scores indicating greater severity of depression.

    Measured: Baseline and post-treatment

Questions about this trial

What is this clinical trial studying?

A Phase 2 study testing Intranasal Insulin in people with Parkinson Disease and Multiple System Atrophy, run by Peter Novak 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 4 inclusion and 6 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 23 Nov 2018. 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 23 Nov 2018). 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?

Change in Verbal Fluency FAS (F, A or S Words) Total Score (time frame: Baseline and post-treatment). It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT02064166, which also lists 1 linked publication.

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 23 Nov 2018.
