`
`Abstract
`
`Background Terbinafine nail solution (TNS) was developed for the treatment of onychomycosis.
`Objective To assess the efficacy of TNS vs. vehicle and amorolfine 5% nail lacquer.
`Methods Subjects with mild-to—moderate toe onychomycosis (25% to 375% nail-involvement, matrix uninvolved)
`were randomized to receive either TNS or vehicle in two double-blind studies, and to TNS or amorolfine in an active-
`controlled, open-label study. Primary endpoint was complete cure (no residual clinical
`involvement and negative
`mycology) at week 52. Secondary endpoints were mycological cure (negative mycology defined as negative KOH
`microscopy and negative culture) and clinical effectiveness (s10% residual-involvement and negative mycology) at
`week 52.
`
`Results Complete cure was not different between TNS vs. vehicle and amorolfine. Mycological cure was higher
`with TNS vs. vehicle, as was clinical effectiveness with TNS vs. vehicle, and TNS and amorolfine were not different
`for secondary efficacy endpoints. Patients achieving mycological cure had a better clinical outcome, and efficacy
`was improved in subjects with milder disease. Post hoc analysis suggests that nail thickness is an important
`prognostic factor. Moreover, mycological cure may require 6 months of treatment regimen while complete cure and
`clinical effectiveness may be achievable only after 10 months. A simulation study suggests that longer treatment
`duration would have resulted in higher complete cure with TNS vs. vehicle. Study treatments were well-tolerated.
`Conclusion Primary efficacy objectives were not met in the studies reported herein. Possible reasons for failure to
`achieve significant outcomes include insufficient length of treatment; stringency of primary endpoint and severity of
`nail involvement of study population.

`
`Introduction
`
`Onychomycosis is the most common cause of nail dystrophy,
`affecting 12-13% of the general population,1’7 and 25% of the
`geriatric and diabetic popL1lation.6’8’9 The disease can be painful or
`cause functional disability, psychosocial problems and compro-
`mised quality of life.‘°"2
`Topical treatments are generally reserved for mild cases of ony-
`chomycosis as they are less effective than systemic oral therapy
`due to reasons including poor penetration, less depot effect and
`less depot area.” However, systemic therapy is not recommended
`in some patients due to the risk of possible drug—drug interactions
`and patient co-morbidities.”’15 Because of the slow growth rate of
`toenails, treatment of toe onychomycosis is more challenging than
`finger onychomycosis and it may take up to 18 months of therapy
`to achieve clearance.]("2° Although topical agents like amorolfine
`5% (marketed in Europe) and ciclopirox 8% (available in Europe
`and US) formulated as lacquers have improved drug delivery to
`nails,2I cure rates are lower than with systemic therapy and
`re-infection or relapse often occurs, as is the case with oral anti-
`fungal tl1erapy.”’l6’22’23
`Terbinafine, a synthetic allylamine is a well-established broad-
`spectrum anti-fungal drug,“ with unique clinical efficacy combined
`with good tolerability.17’25 Based on the reservoir effect observed
`with a film-forming solution of terbinafine l%26’27 (allowing for a
`single-application treatment of interdigital
`tinea pedis), a nail
`solution [topical
`terbinafine HC1 nail
`solution (TNS)] was
`developed. This formulation demonstrated mycological and clinical
`efficacy in in vitro28 models of onychomycosis and was superior to
`ciclopirox 8% nail lacquer in a Phase II study.” This article presents
`results from three large clinical studies [two vehicle-controlled
`(2301 8t 2302) and one active comparator-controlled study
`(2303)] which assessed efficacy and safety of TNS used for 24
`weeks and 48 weeks in patients with mild-to-moderate toenail
`onychomycosis.
`
`Methods
`
`Study design
`
`controlled study, subjects received either TNS or amorolfine 5% nail
`
`lacquer for 48 weeks followed by a treatment free period of 4 weeks.
`The total duration of each study was 52 weeks. Subjects were
`randomized using a validated automated system in equal ratios.
`The studies were conducted in accordance with the ethical prin-
`ciples specified in the Declaration of Helsinki and in compliance
`with the requirements of local regulatory committees and all sub-
`jects provided written informed consent.
`
`Subjects
`
`Subjects aged 12-75 years with mild-to-moderate toe onychomy-
`cosis of the great toenail due to dermatophytes were included.
`Mild-to-moderate toe onychomycosis was defined as a toenail
`involvement of 225% to 575% without spikes and without matrix
`(lunula) involvement, and nail infection was confirmed by positive
`KOH microscopy and culture of a dermatophyte. The subjects
`who had nail abnormalities, obscuring appearance of infection-free
`normal nail (including traumatic or onychogryphotic nail) or in
`whom the target toenail had <2 mm unaffected nail plate length
`beyond the proximal fold were excluded. Also excluded were those
`
`with severe plantar tinea pedis requiring systemic therapy, mixed
`infections (dermatophyte and non-dermatophyte), der1natophy-
`toma (thick masses of fungal hyphae between the nail plate and
`nail bed),3° those receiving systemic or topical anti-fungal therapy
`within 6 months or 3 months, respectively, and those who used
`any commercial topical nail medication within 1 month. Subjects
`with severe diabetic foot neuropathy, malignancy, and sensitivity
`to the study medication were also excluded.
`
`Treatment
`
`Terbinafine nail solution or vehicle were supplied in identical
`packaging and were to be applied daily to all affected toenails with
`no surgical debridement, chemical avulsion, excessive grinding or
`filing of diseased nails. Amorolfine 5% nail lacquer was supplied
`as commercially available and was used as per label, twice weekly
`and with filling of the nails, as described in the package insert.
`
`Efficacy and safety assessments
`
`In the vehicle-controlled studies, subjects received either TNS or
`vehicle for 24 weeks or 48 weeks followed by a treatment free period
`of 28 weeks or 4 weeks respectively. In the active comparator-
`
`The primary efficacy measure was the proportion of subjects achiev-
`ing complete cure (no residual clinical involvement and negative
`KOH and culture) of the target toenail at week 52. The secondary

`
`
`efficacy endpoints were rates of mycological cure (negative KOH
`microscopy and negative culture for dermatophyte), clinical effec-
`tiveness (S10°/> residual involvement of the target toenail, negative
`culture and negative KOH microscopy) and clinical cure (no resid-
`ual involvement of the target toenail) at week 52. In addition, the
`proportion of subjects achieving a negative culture and 250%
`decrease in per cent involvement of the target toenail was analyzed.
`The safety assessments included monitoring and recording of all
`adverse events until week 52.
`
`Susceptibility testing
`
`Terbinafine susceptibility, expressed as minimum inhibitory con-
`centration (MIC) and minimum fungicidal concentration (MFC),
`for all strains isolated at baseline was assessed using the method
`
`developed under auspices of the Clinical and Laboratory Standards
`Institute (CLSI)."’32
`
`Statistical analyses
`Data from the two vehicle-controlled studies were combined for
`
`analysis. The intent-to-treat (ITT) population included all subjects
`who were randomized and
