Trial Outcomes & Findings for Study to Compare Active Tymbion Iontophoresis to Sham Tymbion Iontophoresis for Anesthesia of the Tympanic Membrane (NCT NCT03119181)

NCT ID: NCT03119181

Last Updated: 2020-01-18

Results Overview

The VAS consists of a 100 millimeter (mm) line with a statement at each end representing the extreme limits of pain intensity (where 0 represents "No pain" and 100 represents "The worst imaginable pain"). The subject reports their pain intensity by making a mark along the line and the line is measured to convert the subject response to numeric score (0-100 in millimeters). The data will be summarized as the difference in mean VAS scores between the two treatment groups (active Tymbion iontophoresis compared to sham Tymbion iontophoresis).

Measure
Active Tymbion Iontophoresis
Unilateral treatment with active iontophoresis of Tymbion (2% lidocaine HCl/ 1:100,000 epinephrine) using the Tusker Medical Tula Iontophoresis System. Device: Iontophoresis System (IPS) with Drug: Tymbion lidocaine/epinephrine solution: The external ear canal will be filled with Tymbion drug solution. The Iontophoresis System (IPS) will be used to deliver current to the Tymbion solution to facilitate drug penetration into the tympanic membrane (TM) tissue to anesthetize (numb) the TM
Sham Tymbion Iontophoresis
The sham iontophoresis procedure will be identical to the active Tymbion iontophoresis in that Tymbion (2% lidocaine/ 1:100,000 epinephrine solution) will be placed in the external ear canal, however the iontophoresis current delivery (which facilitates penetration of drug into the tympanic membrane tissue) will not be activated. Tymbion Lidocaine/epinephrine solution: The external ear canal will be filled with Tymbion drug solution
