What is being measured

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

  1. Evaluate the safety and tolerability of repeat injections of CNTX-4975 through assessment of incidence, intensity, relationship and seriousness of treatment-emergent adverse events

    Measured: over the course of 1 year.

  2. Evaluate the safety and tolerability of repeat injections of CNTX-4975 through treatment-emergent changes in vital signs and laboratory tests

    Measured: over the course of 1 year.

Secondary outcomes (2)
  1. To evaluate the analgesic efficacy of repeat doses of CNTX-4975 by change in NPRS.

    Measured: over the course of 1 year.

  2. To evaluate the analgesic efficacy of repeat doses of CNTX-4975 by change in Patient Global Impression of Change

    Measured: over the course of 1 year.

Questions about this trial

What is this clinical trial studying?

A Phase 2 study testing CNTX-4975 in people with Morton's Neuroma, run by Centrexion Therapeutics at 10 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 10 inclusion and 8 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 May 2018. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 10 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?

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?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

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?

Evaluate the safety and tolerability of repeat injections of CNTX-4975 through assessment of incidence, intensity, relationship and seriousness of treatment-emergent adverse events (time frame: over the course of 1 year.). 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 9 May 2018.
