Eligibility Criteria
Inclusion
- Confirmation of the presence of fungal infection through a positive KOH stain finding and a positive fungal culture finding
- Identification through fungal culture of the growth of Trichophyton rubrum (T. rubrum) or other common dermatophyte
- Visual clinical presentation of onychomycosis in the target great toenail is distal subungual onychomycosis (DSO), visualized as a nail with normal surface texture and thickness but variable "bays" of white nail that extend from the distal nail tip proximally into the area of the nail bed
- Clinical involvement of onychomycosis in the target toenail is between 20%-50%
- Subject is willing and able to refrain from employing other (non-study) treatments (traditional or alternative) for his or her toenail onychomycosis throughout study participation.
- Subject is willing and able to refrain from the use of nail cosmetics such as clear and/or colored nail lacquers throughout study participation
- Male or female
- 18 years of age or older
Exclusion
- Lack of confirmation of the presence of fungal infection through a negative KOH stain finding and/or a negative fungal culture finding
- Visual clinical presentations of onychomycosis in the target great toenail that are inconsistent with the clinical presentation of distal subungual onychomycosis (DSO), in whole or in part (i.e. indicative of mixed etiology); specifically visual clinical presentations consistent with one or more of the following:
- Proximal subungual onychomycosis (PSO): visualized as a white discoloration below the nail plate at the base of the nail, near the lunula. The distal nail retains normal appearance and texture. PSO involves infection near the matrix, deep to the nail. It may be associated with trauma to the nail or to immune compromise
- Superficial white onychomycosis (SWO): visualized by the appearance of a white coating on the nail surface that can be eliminated by filing or buffing the surface of the affected portion of the nail
- Complete dystrophy: Nails which are 100% dystrophic are manifested by yellowing and thickening of the entire nail unit
- Other nail changes: Nails that visually present with changes that appear as parallel lines, small pinpoint depressions, brown spots, black or brown linear streaks, complete yellowing of all nails without textural change, green debris below the nail, or notches in the nail margin
- Less than 2mm clear (unaffected) nail plate length beyond the proximal fold
- Presence of dermatophytoma (thick masses of fungal hyphae and necrotic keratin between the nail plate and nail bed)
- Infection involving lunula e.g., genetic nail disorders, primentary disorders
- Severe plantar (moccasin) tinea pedis
- Psoriasis of the skin and/or nails, lichen planus, or other medical conditions known to induce nail changes
- Onychogryphosis
- Trauma from ill-fitting shoes, running, or overly-aggressive nail care
- Previous toenail surgery
- Uncontrolled diabetes mellitus
- Peripheral vascular disease
- Recurrent cellulitis
- Lymphatic insufficiency
- Immune compromise (whether due to underlying medical disorders or immunosuppressive treatments)
- Other compromised states of health
- Known photosensitivity disorder
- Use of oral antifungal drugs in the prior 6 months
- Use of topical treatment of the skin or nails within the prior 2 months
- Any abnormality of the toenail that could prevent a normal appearing nail from occurring if clearing of infection is achieved.
- Current trauma, open wound on or about the treatment area
- Deformity of the target toe/toenail secondary to fungal infection/onychomycosis due to prior injury, surgical procedures or another medical condition
- Pregnant or planning pregnancy prior to the end of study participation
- Serious mental health illness such as dementia or schizophrenia; psychiatric hospitalization in the past two years
- Developmental disability or cognitive impairment that would preclude adequate comprehension of the informed consent form and/or ability to follow study subject requirements and/or record the necessary study measurements
- Involvement in litigation and/or receiving disability benefits related in any way to the parameters of the study
- Participation in a clinical study or other type of research in the past 30 days.
