About this study

The overall aim of this clinical study is to develop a general bioequivalence (BE) testing method using dermal open flow microperfusion (dOFM) for dermatological drug products. In this study BE of different lidocaine/prilocaine products will be assessed and factors that influence dOFM data variability will be evaluated.

Read the detailed description

The study will involve 20 healthy adult participants. Dermal pharmacokinetic (PK) profile of three different lidocaine/prilocaine products will be assessed in parallel at different skin sites on the same participant.

For BE evaluations a reference product will be compared against itself and an approved generic test product as positive control and against a non-equivalent test product as negative control. Additionally different non-invasive measurements (e.g. TEWL) will be conducted and results will be correlated with lidocaine/prilocaine PK data to identify factors that might influence skin penetration.

dOFM probes will be inserted into the dermis to monitor the dermal drug concentrations up to 12 h post-dose in topically treated skin sites. Blood samples will be drawn to rule out systemic appearance of lidocaine and/or prilocaine.

Being tested
Lidocaine 2.5% and Prilocaine 2.5% cream, USP (Actavis Pharma incorporated, USA), Lidocaine 2.5% and Prilocaine 2.5% cream (E. Fougera & Co. a division of Fougera Pharmaceuticals Inc., USA), Oraqix Parodontal-Gel (Dentsply Detrey GmbH, Germany), Dermal open flow microperfusion, Blood sampling

Study groupRoleWhat they receive
Dermal Pharmacokinetic studyExperimentalMeasurement of dermal pharmacokinetic (PK) parameter (AUC, Cmax) of lidocaine/ prilocaine using dOFM after topical application of three lidocaine/prilocaine products in 20 participants. After baseline sampling (1 hour pre-dose) the three lidocaine/prilocaine products will be applied and removed after 3 hours. ISF and blood sampling will be continued for a duration of 12 hours post-dose. Additionally different physical parameters (e.g. TEWL) will be measured.
Receives: Drug: Lidocaine 2.5% and Prilocaine 2.5% cream, USP (Actavis Pharma incorporated, USA); Drug: Lidocaine 2.5% and Prilocaine 2.5% cream (E.

What is being measured

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

  1. Area under the dermal concentration versus time curve for lidocaine

    Dermal concentrations (ng/mL) of lidocaine will be measured to calculate the area under the dermal concentration versus time curve AUC (ng*h/mL).

    Measured: 13 hours

  2. Area under the dermal concentration versus time curve for prilocaine

    Dermal concentrations (ng/mL) of prilocaine will be measured to calculate the area under the dermal concentration versus time curve AUC (ng*h/mL).

    Measured: 13 hours

  3. Maximal dermal concentration of lidocaine

    Dermal concentrations (ng/mL) of lidocaine will be measured to calculate the maximal dermal concentration (ng/mL).

    Measured: 13 hours

  4. Maximal dermal concentration of prilocaine

    Dermal concentrations (ng/mL) of prilocaine will be measured to calculate the maximal dermal concentration (ng/mL).

    Measured: 13 hours

Secondary outcomes (2)
  1. Blood lidocaine concentrations versus time curve

    Lidocaine concentrations (ng/mL) in the blood will be measured to obtain the concentration-time curves in the blood.

    Measured: 13 hours

  2. Blood prilocaine concentrations versus time curve

    Prilocaine concentrations (ng/mL) in the blood will be measured to obtain the concentration-time curves in the blood.

    Measured: 13 hours

The record lists 1 site in Austria. 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.

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?

Area under the dermal concentration versus time curve for lidocaine (time frame: 13 hours). 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 NCT04050826, which also lists 5 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 12 Oct 2020.
