Evaluation of Safety of Low Level Laser Device Treatment in Chronic Wounds


This is a randomized, double blind, placebo-controlled study to evaluate the safety of the low level laser MC-8XL device treatment in subjects with an unsuccessfully treated Diabetic Foot Ulcer (DFU) that has been present for at least 3 months.

Eligible subjects will be randomized to either Treatment group or Control group, following which, treatment of each subject will be provided by a qualified nurse at the clinic or in the home setting, everyday for up to 16 weeks.

Study assessments and adverse events monitoring will be also performed throughout the study.

Study Type

  • Study Type: Interventional
  • Study Design
    • Allocation: Randomized
    • Intervention Model: Parallel Assignment
    • Primary Purpose: Other
    • Masking: Double (Participant, Investigator)
  • Study Primary Completion Date: June 14, 2018


  • Device: MC-8XL low level laser device and Standard wound care
    • The MC-8XL, a handheld Low Level Laser Therapy (LLLT) device, comprised of an infrared laser diode that generates wavelength of 808 nm and a green laser diode with a wavelength of 525 nm will be used to treat the experimental group. Along with the active LLLT, generally accepted standard wound care procedures will be used during the clinical trial by a qualified study nurse or doctor. These procedures will include wound cleaning and drying before irradiation with the laser device (sham or active). Each ulcer will be also assessed and debrided if needed. After irradiation, each ulcer will be dressed with saline gauze dressing and offloaded.
  • Device: Sham laser device and Standard wound care
    • The Sham device is of similar appearance, emitting only green light for indication with a wavelength of 525 nm of a low power, with inactive IR laser which will be used in the Control group. Along with the sham device, the same generally accepted standard wound care procedures will be used.

Arms, Groups and Cohorts

  • Experimental: Treatment group
    • The treatment group will be treated with the MC-8XL laser device, emitting 808 nm laser beam with a green laser beam. Intervention: MC-8XL low level laser device and Standard wound care
  • Sham Comparator: Control group
    • The control group will receive treatment with a sham laser device, emitting a low power green light with inactive Infrared (IR) laser for indication only. Intervention: Sham laser device and Standard wound care

Clinical Trial Outcome Measures

Primary Measures

  • Safety
    • Time Frame: On a weekly basis until the end of the 16 week treatment period
    • assessing device related and general adverse events

Secondary Measures

  • Wound Healing
    • Time Frame: On a weekly basis until the end of the 16 week treatment period or until complete wound closure
    • Percent of wounds achieving complete wound closure, wound granulation and percent change in ulcer size/area

Participating in This Clinical Trial

Inclusion Criteria

  • Provide signed and dated Informed Consent Form
  • Willing to comply with all study procedures and be available for the duration of the study
  • Male or female, aged 18 to 90

  • Presence of any suspicious pre-cancerous or cancerous lesions, or having cancer.
  • Being on medications that are immunosuppressive, may affect peripheral blood flow or may affect normal wound healing.
  • Being on medications that might cause photosensitivity.
  • Participation in any other clinical trial testing a device or drug.
