Clinical Trial Summary

The purpose of this clinical study is to determine the effectiveness of the Erchonia® EVRL™, manufactured by Erchonia Corporation (the Company), in providing prescription home use application for temporary relief of diabetic neuropathy foot pain in individuals diagnosed with diabetic neuropathy by a suitably qualified and licensed health professional.

Description:

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 EVRL™ Use Device Proper Use Reference Guide, and device packaging and labeling materials to correctly, safely, and successfully activate and operate the EVRL™ 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® EVRL™, manufactured by Erchonia Corporation (the Sponsor), for prescription home use application in providing temporary relief of diabetic peripheral neuropathy foot pain.

Eligibility

Inclusion Criteria:

• Previously diagnosed with diabetes induced peripheral neuropathy by a suitably qualified and licensed health professional within the past 6 months
• Over the age of 18 years of age
• Able to read and write English.
• Constant feet pain on-going over at least the past 3 months.
• If using analgesics (pain medication), you must be on a stable analgesic regimen (i.e., no changes to the prescribed analgesic regimen) over a period of at least 14 days prior to enrollment; and willing and able to not have planned upward dose titration of analgesics during the study period. You may elect to decrease analgesic use during the study. Cannabis prescribed for medicinal purposes would qualify as an analgesic in this context.
• Willing and able to refrain from engaging in any non-study procedure therapies for the management of foot pain throughout the course of study participation, including conventional therapies such as physical therapy, occupational therapy and hot or cold packs, as well as alternative therapies such as chiropractic care and acupuncture.
• Agrees to refrain from taking a dosage of analgesic (pain medication) for at least 6 hours before a scheduled VAS foot pain rating is to be recorded.
• Subjects' degree of foot pain on the 0-100 VAS, with "0" being no pain and "100" being worst pain imaginable, is 50 or greater.

Exclusion Criteria:

• Pregnant or think you might be pregnant.
• Open wounds (sores, cuts, ulcers, etc) around the feet
• Cancerous growths around the feet
• Difficulty with hand dexterity sufficient to impact ability to administer treatments with the laser such as from severe arthritis in the hands, Multiple Sclerosis, Cerebral Palsy, Parkinson's Disease, Huntington's Disease, etc.

Intervention

Device:
• Erchonia® EVRL™
The Erchonia® EVRL™ is made up of (1) 635 nanometers red laser diode and (1) 405 nanometers violet laser diode mounted in a portable handheld device. The diodes are positioned approximately 3 to 6 inches from the top of the foot. The treatments will be self-administered by the subject at his or her's place of residence, two times per day for 21 days. Each procedure administration lasts 5 minutes per foot, for a total of 10 minutes.
• Placebo Laser
The Placebo Laser has the same appearance as the Erchonia® EVRL™ but does not emit any therapeutic light. The diodes are positioned approximately 3 to 6 inches from the top of the foot. The treatments will be self-administered by the subject at his or her's place of residence, two times per day for 21 days. Each procedure administration lasts 5 minutes per foot, for a total of 10 minutes.

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Number of Participants With a 30% or Greater Change in Pain Rating on the Visual Analog Scale (VAS)	The Visual Analog Scale (VAS) from baseline to endpoint (6 weeks) measurement is calculated for each subject. Individual subject success is defined as a 30% or greater change in VAS pain scores across the evaluation period. A negative (-) percent change indicates a decrease in pain level and is positive for individual subject success. A lower Visual Analog Scale pain score from baseline to study endpoint represents a better outcome, whereas a higher score from baseline to study endpoint represents a worse outcome.; For the primary study outcome, the overall study success is defined as a 35% or greater difference between the proportion (number) of individual successes in each treatment group.	Baseline and 3 weeks
Secondary	Neuropathic Pain Symptom Inventory (NPSI)	The NPSI is a 12-item self-administered patient-reported outcome (PRO) assessment tool with a recall/ observation period of over the past 24 hours. It contains 10 descriptors representing 5 distinct dimensions on the basis of factor analysis: burning pain, deep pain, paroxysmal pain, evoked pain, paresthesia/dysesthesia, and 2 temporal items designed to assess pain duration and the number of pain paroxysms. The NPSI has been validated in patients with definite neuropathic pain of peripheral or central origin.	Baseline and 3 weeks
