Efficacy of the Erchonia Corporation THL™ for Providing Relief of Tinnitus Symptoms

Clinical Efficacy and Human Factors Validation Testing for Prescription Home Use of the Erchonia Corporation THL™ for Providing Relief of Tinnitus Symptoms

The purpose of this clinical study is to determine the effectiveness of the Erchonia® THL™, manufactured by Erchonia Corporation (the Company), for prescription home use in providing relief of tinnitus symptoms when used by individuals in their own homes.

Human Factors Validation Testing will initially be conducted to valuate a lay person's ability to understand and apply as applicable the information contained in the THL™ Use Device Proper Use Reference Guide, and device packaging and labeling materials to correctly, safely, and successfully activate and operate the THL™ to administer the treatment; and to identify any and all use difficulties, problems and errors, including those pertaining to critical tasks and close calls demonstrated by the lay person during device operation, and to subsequently mitigate each identified instance of use error through device and/or materials modification, and to subsequently evaluate the effectiveness of each modification, as applicable

Phase Two will commence following the successful completion of Phase One. Phase Two comprises the performance of a double-blind, randomized, placebo-controlled, clinical study of the efficacy of the Erchonia® THL™, manufactured by Erchonia Corporation (the Sponsor), for prescription home use application in providing relief of tinnitus symptoms when used by individuals in their own homes.
