This is an open, single site, pilot study in Canadian subjects diagnosed with mild to moderate toenail onychomycosis caused by dermatophytes. A total of 45 subjects will be enrolled in the study. All eligible subjects who provide written informed consent will be randomized to one of three groups (15 subjects in each group): Group A, B or C.~The treatment regimen for each group is as follows:~Group A: Subjects will receive treatment on Day 0 and then weekly in the first month followed by monthly treatment for a further 4 months (9 treatments).~Group B: Subjects will receive treatment on Day 0 and then every two weeks in the first month followed by monthly treatment for a further 4months (7 treatments).~Group C: Subjects will receive treatment on Day 0 and then once every two weeks in the first six months (12 treatments).~For all groups, patients not achieving 'FDA efficacy' levels at Month 6 End Visit and/or Month 9 End Visit will be offered continuation of treatments once monthly for 3 months to determine if additional treatment will continue to be safe and increase efficacy. Patients may refuse additional treatment, while continuing in safety follow-up to Months 9/12.~Subjects will be followed up every 3 months for safety and efficacy to Month 12, and at any treatment intervals occurring between these main visits. Efficacy will be assessed by changes in affected nail area and length, both in clinic and through photos. Mycology sampling will be performed at pre-determined intervals to assess fungal presence and viability post-treatment.
This is an open, single site, pilot study in Canadian subjects diagnosed with mild to moderate toenail onychomycosis caused by dermatophytes. Three microwave treatment frequencies will be compared for efficacy and safety, evaluated by frequency of treatment-related adverse events, clinical improvement of a treated target toenail and inactivation/elimination of fungus in the target toenail. Outcomes will be evaluated at Month 6, Month 9 and Month 12 after initiation of treatments. Subjects not achieving 'temporary increase in clear nail' at Month 6 may receive extra microwave treatments to Month 9 or Month 12 to improve outcomes.
