What is being measured

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

  1. Capsaicin Pharmacokinetics - AUC0-t

    Single-dose systemic exposure to trans- and cis-capsaicin measured by AUC0-t.

    Measured: Day 1 (pre-dose to 12 hours post-dose) and Day 8 (pre-dose to 12 hours post-dose)

  2. Capsaicin Pharmacokinetics - AUC0-inf

    Single-dose systemic exposure to trans- and cis-capsaicin measured by AUC0-inf.

    Measured: Day 1 (pre-dose to 12 hours post-dose) and Day 8 (pre-dose to 12 hours post-dose)

  3. Capsaicin Pharmacokinetics - Cmax

    Single-dose systemic exposure to trans- and cis-capsaicin measured by Cmax.

    Measured: Day 1 (pre-dose to 12 hours post-dose) and Day 8 (pre-dose to 12 hours post-dose)

Secondary outcomes (3)
  1. Knee Injury and Osteoarthritis Outcome Score (KOOS) Assessment

    Change from baseline in KOOS of IA injected knees; 5-point Likert scale: 0 (no problems) to 4 (extreme problems); 5 subscales; each assessed separately

    Measured: Day 1 (pre-dose) or Day 8 (pre-dose) [cross over trial Qutenza® 8% patch or CNTX-4975-05 intra-articular (IA) knee injection], and Week 8 (follow-up)

  2. Incidence of treatment-emergent adverse events (TEAEs) (safety and tolerability)

    Number of participants with TEAEs, which includes laboratory test variables

    Measured: Day 1 (post-dose), Day 8 (post-dose), and Week 8 (follow-up)

  3. IA knee Lidocaine Systemic Pharmacokinetics - Concentration

    System exposure to lidocaine measured by plasma concentration

    Measured: Day 1 (pre-dose to 3 hours post-dose) or Day 8 (pre-dose to 3 hours post-dose) [Cross over trial Qutenza® 8% patch or CNTX-4975-05 IA knee injection]

Questions about this trial

What is this clinical trial studying?

A Phase 1 study testing CNTX-4975-05, Qutenza and Lidocaine (without epinephrine) in people with Knee Osteoarthritis, run by Centrexion Therapeutics 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 2 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 14 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. 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 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?

Capsaicin Pharmacokinetics - AUC0-t (time frame: Day 1 (pre-dose to 12 hours post-dose) and Day 8 (pre-dose to 12 hours post-dose)). The study lists 3 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 14 Nov 2018.
