Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Detailed Description

This clinical study is a single-arm, active treatment group only, non-inferiority prospective design to evaluate the efficacy of the Erchonia® EVRL™ for prescription home use application in providing temporary relief of foot pain due to idiopathic peripheral neuropathy. There will be a single active treatment only subject group in this study. All enrolled subjects will self-administer the treatments with the active (true) Erchonia® EVRL™ laser in his or her own home.

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

  • Adult
  • Older Adult

Accepts Healthy Volunteers

No

Description

Inclusion Criteria:

  • Previously diagnosed with idiopathic peripheral neuropathy by a suitably qualified and licensed health professional within the past 6 months.
  • Over the age of 22 years of age
  • Able to read and write English
  • Constant feet pain on-going over at least the past 3 months
  • Subjects using analgesics (pain medication) 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 study enrollment; and be willing and able to not have planned upward dose titration of analgesics during the study period. Decreasing frequency of analgesic use during the study is permitted. Cannabis prescribed for medicinal purposes qualifies as an analgesic in this context
  • Willing and able to refrain from engaging in any non-study therapies for the management of foot pain throughout the course of study participation, including conventional therapies such as physical therapy, occupational therapy, hot or cold packs, and 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
  • Subject's 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:

  • Diabetic, referred to as having hemoglobin A1c (HbA1C) of 6.5% or higher
  • Previously diagnosed with any definitive (i.e. not idiopathic) cause of peripheral neuropathy by a suitably qualified and licensed health professional within the past 6 months, such as diabetes, injury, infection, toxins and poisons, alcoholism, medications such as chemotherapy, autoimmune disorders, etc..
  • Pregnant or possibly pregnant, breastfeeding, or planning pregnancy during the intended course of study participation
  • Open wounds (sores, cuts, ulcers, etc.) on or around the treatment area on the feet
  • Cancerous growths or lesions on or around the treatment area on the feet
  • Difficulty with hand dexterity sufficient to negatively impact the 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 / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available.

Experimental: 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.
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.

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Number of Participants With a 30% or Greater Change in Pain Rating on the Visual Analog Scale
Time Frame: Baseline and 3 weeks
The Visual Analog Scale (VAS) will be used to assess pain from baseline to the 6-week endpoint for each subject. Subjects will be instructed to indicate the overall level of pain experienced in their feet by placing a cross (X) on a 10-centimeter horizontal line. The left end of the line will be labeled "0," representing "no pain," and the right end will be labeled "100," representing "the worst pain imaginable." 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 VAS pain score from baseline to study endpoint represents a better outcome, whereas a higher score from baseline to study endpoint represents a worse outcome.
Baseline and 3 weeks

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Measure Description
Time Frame
Neuropathic Pain Symptom Inventory
Time Frame: Baseline and 3 weeks
The Neuropathic Pain Symptom Inventory (NPSI) is a 12-item self-administered patient-reported outcome 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 a maximum total score of 100, a lower score from baseline to study endpoint represents a better outcome.
