About this study

This study plans to learn more about whether a nicotine-like investigational new drug, DMXB-A [3-(2,4-dimethoxybenzylidene) anabaseine] may have positive effects on mental focus and may help us to find new types of treatment for autism spectrum disorder. Subjects will come in for a screening visit and three more drug visits. There will be at least one week between each drug visit to allow the drug to be eliminated from your system completely. During each drug visit subjects will receive either a placebo (a capsule that looks like medicine but is not real), 75 mg of DMXB-A, or 150 mg of DMXB-A. During the drug day vital signs and well being will be monitored by the study physician. Subjects will complete some paper and pencil tasks to test memory, attention, speed, and problem solving, some rating scales and questionnaires, and the study team will record brain wave patterns with an electroencephalogram (EEG) .

What is being measured

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

  1. Difference between drug and placebo on theTotal Scale Score on the repeatable Battery for the Assessment of neuropsychological Status at 2 hours after administration

    Measured: 2 hours after drug administration

  2. Difference between drug and placebo on the CPT at 30 minutes after administration

    Measured: 30 minutes after drug administration

  3. Difference between the P50 auditory evoked potential test/conditioning ratio 1 hour after administration

    Measured: 1 hour after drug administration

  4. Difference between placebo and drug on the Social Responsiveness scale 2 hours after administration

    Measured: 2 hours after drug administration

Questions about this trial

What is this clinical trial studying?

A Phase 1 study testing DMXB-A 150 mg and DMXB-A 75 mg in people with Autism, run by University of Colorado, Denver 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: stopped early, as of the sponsor's last update on 16 Jun 2016. 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 1 studies test a treatment in a small group of people for the first time or in a new way, mainly to check safety and find the right dose.

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

Are results available for this study?

The study was stopped early (reason given: difficult to find participants and no funding). Results are not available in the source record.

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?

Difference between drug and placebo on theTotal Scale Score on the repeatable Battery for the Assessment of neuropsychological Status at 2 hours after administration (time frame: 2 hours after drug administration). The study lists 4 primary outcomes in all. 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 NCT02111551, 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 16 Jun 2016.
