Design outcomes

Primary

MeasureTime frameDescription
Number of subjects diagnosed with presence of subungual culture after 3rd treatment session3 weeks after baselineBased on presence of fungal infection from culture assessment
Number of subjects with clinical cure based on photographs after the 3rd treatment session3 weeks after baselineBased on visual assessment of photographs: presence or absence of fungal infection

Secondary

MeasureTime frame
Compare rates of mycological and clinical cure after three treatments between two groups with different ALA incubation times3 weeks after baseline
Evaluate the durability of treatment outcomes with subungual culture and photographs at 24 weeks24 weeks after first treatment
Evaluate tolerability to treatment using a Visual Analog Scale (VAS) pain scale questionnaire at each treatment visit1 week after baseline
