About this study

Official title: Assessing the Frequency of Lidocaine Ineffectiveness in the General Population vs. Males With ADHD, and Females With ADHD, With or Without PMS

This work will assess the prevalence in the general population of the ineffectiveness of the anesthetic Lidocaine compared to males with ADHD and females with ADHD with or without PMS.

Read the detailed description

Using a non-invasive, pain-free, taste-based approach to assess lidocaine effectiveness, the study will assess the frequency of ineffectiveness in the target population. We will use an identical protocol at two sites: Jacobi hospital and Boston Clinical Trials.

The controlled trial will assess the ability of lidocaine oral gel to block taste (e.g., sweet) in 100 teens and adults, half with a history of ADHD, and for females, we will compare the sub-groups with and without premenstrual syndrome (PMS).

This study will also be compared with a similar assessment among a specialized ADHD population (NCT03563573), that does not respond to existing medication..

What is being measured

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

  1. Number of Subjects With Lidocaine Ineffectiveness

    Subjects will be asked to identify each taste and its intensity on a 0 (no taste) to 10 (very intense) scale before and after application of Lidocaine. Lidocaine effectiveness was quantitated as the reduction or elimination of taste by lidocaine compared to taste scores reported before lidocaine. For each of the four before/after pairs, the change in taste intensity was calculated, a weighted average score was computed. Incorrectly identified tastes were excluded. Scores of a reduction in taste ≥50% were considered to be lidocaine effective.

    Measured: 30 minute visit, added on to a regular clinic visit

Questions about this trial

What is this clinical trial studying?

A Early Phase 1 study testing Lidocaine gel in people with ADHD and PMS, run by PhenoSolve, LLC at 2 sites 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 0 inclusion and 1 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 6 Oct 2022. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 2 sites 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.

What does this phase mean?

Early Phase 1 (sometimes called Phase 0) studies give a very small amount of a treatment to a few people, mainly to see how the body handles it.

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 14 Jul 2021). 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?

Number of Subjects With Lidocaine Ineffectiveness (time frame: 30 minute visit, added on to a regular clinic visit). 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 NCT03676725, which also lists 7 linked publications.

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 6 Oct 2022.
