Who may be able to join

  • Subject is a male or female ≥ 18 years of age and ≤ 85 years of age.

What is being measured

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

  1. To evaluate the safety of topically applied 40% lidocaine gel measuring incidence, intensity, relationship, and seriousness of treatment-emergent AEs

    Measured: 28 days

  2. To evaluate the pharmacokinetics of topically applied 40% lidocaine gel measuring Tmax

    Measured: 28 days

Secondary outcomes (1)
  1. To assess the effect of 40% lidocaine gel on 0-10 numeric pain rating scale (NPRS) scores related to acute herpes zoster

    Measured: 28 days

Questions about this trial

What is this clinical trial studying?

A Phase 1 study testing CNTX-2022 (lidocaine gel, 40%) in people with Acute-onset Herpes Zoster Pain, run by Centrexion Therapeutics at 1 site in Australia.

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 6 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 10 Feb 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 Australia. 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: Limited patient enrollment). 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?

To evaluate the safety of topically applied 40% lidocaine gel measuring incidence, intensity, relationship, and seriousness of treatment-emergent AEs (time frame: 28 days). 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 10 Feb 2016.
