Early Feasibility Study to Evaluate the Efficacy and Safety of the RenewalNail™ Plasma Treatment System in Patients With Mild to Moderate Onychomycosis (Fungal Nail)
Early Feasibility Study to Evaluate the Efficacy and Safety of the RenewalNail™ Plasma Treatment System in Patients With Mild to Moderate Onychomycosis (Fungal Nail)
Early feasibility study to determine if a three-treatment protocol with the RenewalNail™
 plasma treatment system over a week will result in mycological cure and/or clear nail growth
 on the treated hallux toe.
The Sponsor has developed the RenewalNail™ plasma treatment system to topically treat fungal
 infected toenails. The goal of the RenewalNail™ therapy is to overcome the shortcomings of
 both topical and oral therapies by combining the safety of a topical treatment with the
 efficacy of an oral treatment.

 The primary objective of this early feasibility study is to evaluate the efficacy and safety
 of the RenewalNail™ plasma treatment system and Protocol in achieving mycological cure for
 the patient. The Protocol calls for three 45-minute treatments performed over a week to
 achieve mycological cure. Mycological cure will be assessed with two consecutive mycological
 culture tests done over a week. Two consecutive negative results will confirm the elimination
 of fungus causing onychomycosis infection, as recommended by recent FDA guidance. There will
 be no placebo arm in the study.

 Secondary objectives include assessing if the treatment protocol results in clear nail growth
 for the patient over a 5-month interval.

 masses) of fungal hyphae and necrotic keratin between the nail plate and nail bed) on
 the target nail;

 -  Subjects with onychomycosis infection involving lunula of the affected toenail(s) or
 spikes of disease extending to nail matrix in the affected big toenail(s);

 -  Subjects with conditions other than distal subungual onychomycosis known to cause
 abnormal nail appearance such as psoriasis, severe moccasin-type tinea pedis requiring
 treatment, symptomatic interdigital tinea pedis, lichen planus, or other abnormalities
 that could result in a clinically abnormal nail;

 -  Subjects whose foot is too large (larger than US men's size 13) or too small (smaller
 than US women's size 3) to properly fit into the plasma treatment device;

 -  Subjects with a history of multiple repeated failures with previous therapies for
 onychomycosis;

 -  Subjects whose affected big toenails cannot become normal in the opinion of the
 investigator;

 -  Subjects with abnormality of the affected big toenail(s) that could prevent a normal
 appearing nail if clearing of infection is achieved;

 -  Subjects with trauma to the affected big toenail(s) as identified by the study doctor;

 -  Subjects who received topical antifungal treatment of the nails within 2 weeks before
 study initiation;

 -  Subjects who received systemic antifungal treatment within 3 months before study
 initiation;

 understand the study and thus give written informed consent;

 -  Simultaneous participation in another clinical study or participation in another
 clinical study in the 30 days directly preceding treatment;

 -  Subjects who are unwilling or unable to refrain from employing other (non-study)
 treatments (traditional and alternative) for their toenail onychomycosis throughout
 study participation;

 condition being studied that, in the opinion of the investigator, would interfere with
 study evaluations or optimal participation in the study;

 -  Subjects who may be unreliable for the study including Subjects who engage in
 excessive alcohol intake or drug abuse (no testing required), or Subjects who are
 unable to return for scheduled follow-up visits;

 -  Subjects who feel they cannot sit for 45 minutes at a time during the treatment.
